30.2 New Features
Added support for Multitrack Video streaming [palana]
On Twitch, this is known as Enhanced Broadcasting. For more information, see: https://help.twitch.tv/s/article/multiple-encodes
The supported audio channel configurations are stereo or mono.
This feature is currently only available on Windows and requires an NVIDIA GTX 900, GTX 10, or RTX 20 series GPU or newer or an AMD RX 6000 series GPU or newer. Support for other operating systems and GPU vendors is planned.
When this feature is enabled, the following data about your system will be sent to the streaming service when starting a stream:
OBS version and audio/video settings (Resolution, framerate, audio channels/tracks)
CPU info (Name, speed, core counts)
GPU info (Model, memory, driver version, device ID, vendor ID)
Memory info (Free, total)
OS info (name, version, arch, emulation)
Windows info (Gaming feature status: Game Bar, Game DVR, Game Mode, Hardware-accelerated GPU Scheduling)
Multitrack Video settings (Maximum streaming bandwidth, maximum video tracks)
Added support for Enhanced RTMP/FLV multi-track audio and video [palana/kc5nra]
Replaces the old metadata-based "VOD Track"
Added "Hybrid MP4" output format (BETA) [derrod]
Combines fault-tolerance of fragmented MP4 with wide compatibility and faster access times of regular MP4. For more information, see: https://obsproject.com/kb/hybrid-mp4

OBS Studio 28.1.1 Hotfix Changes

Fixed NVENC preset not being migrated properly in simple output mode [RytoEX]
Fixed the inability to start the encoder when NVENC is set to a bframe count higher than is supported by the device [RytoEX]


OBS Studio 28.1

NOTE: Some plugins may not be compatible with OBS 28. You can check the status of the most common plugins on the OBS Plugin Compatibility page.

28.1 Changes
Added NVENC AV1 hardware encoder on Windows [Jim]
Currently only works with the NV12 (OBS default) and P010 color formats
Currently does not support the "rescale" feature in advanced output mode
Only available for RTX 40 Series video cards from NVIDIA
Updated NVENC presets [Jim]
Presets have been split into 3 different settings: Preset, Tuning, and Multipass mode
Presets are now P1-P7, lower numbers being lower quality, higher numbers being higher quality. Note that higher presets may incur higher GPU usage which could impact the performance of games running simultaneously with OBS. The number of simultaneous NVENC encoding sessions may be lower when using the highest presets. OBS will automatically map your current NVENC settings to the closest preset when upgrading.
Tuning is used to determine whether to prioritize latency or quality. It has three settings: High Quality, Low Latency, and Ultra Low Latency.
Multipass Mode is used to determine whether a second pass is used in encoding, and has three settings: Disabled, Quarter Resolution, and Full Resolution. Enabling this will give higher quality at the cost of more GPU resource usage.
Fixed a bug where Direct3D 9 games stopped capturing properly with game capture on Windows 11 22H2 [Rodney]

OBS Studio 28.0

If you would like to support the OBS Project, please consider contributing to our Patreon or Open Collective!

NOTE: Some plugins may not be compatible with OBS 28. You can check the status of the most common plugins on the OBS Plugin Compatibility page.

This release marks the 10th anniversary of OBS! 10 years ago today, the first version of OBS was released by Jim. Now we have hundreds of contributors and countless users. We're very grateful for all the support, and we're happy that so many people find it useful!

28.0: 10-bit and HDR Video Encoding Support
OBS now supports 10-bit and HDR, courtesy of rcdrone, YouTube, and Luxoft. New color format and color space settings have been added in the advanced settings to allow this.

Important notes about HDR and 10-bit:

HDR and 10-bit can only be encoded with AV1 and HEVC encoders.
10-bit HEVC encoding requires NVIDIA 10-series, AMD 5000 series, or newer GPU. Intel QuickSync and Apple VT are not yet supported.
The recommended settings for HDR are Color Format P010 and Color Space Rec. 2100 PQ.
If you wish to encode 10-bit SDR, you can use Color Format P010 with an SDR color space (e.g. Rec. 709, Rec. 601). However, AV1 or HEVC will still be required.
HDR streaming is currently only supported via YouTube's HLS service via an HEVC encoder.
When composing in SDR, games that operate in HDR can now be properly tonemapped to SDR.
Video capture devices can be used to capture and stream in HDR if the device supports it (e.g. EVGA XR1 Pro, Elgato 4K60 Pro Mk.2, AverMedia Live Gamer 4K).
For a list of tested devices, see https://obsproject.com/kb/video-capture-devices-with-hdr-support
Certain filters will not function if a source is rendering with HDR:
Apply LUT, Chroma Key, Color Key, Image Mask/Blend, Luma Key, Sharpness
Mac/Linux support is limited. HDR preview does not work, and several inputs/encoders still need to be updated.
28.0: Updating to Qt 6
As of May 2020, version 5 of the Qt user interface toolkit ceased public development and is no longer being updated. Since then, our need for a more up-to-date version has been increasing as time goes by. With version 28.0, we felt it was important for us to update our user interface toolkit to the latest version; not just to gain access to the latest features, but also for the latest bug fixes and improved support for newer operating systems and architectures such as Windows 11 and Apple Silicon. Unfortunately, this also means that certain plugins that depend on version 5 of Qt will no longer work when you upgrade to version 28.0 and will need to be updated.

During this beta period of OBS 28.0, many of those plugins which rely on Qt version 5 may not yet be updated yet, and we'll be working with third-party plugin developers in order to get them updated before the final release deploys.

Additionally, Qt 6 has dropped support for Windows 7 & 8, macOS 10.13 & 10.14, Ubuntu 18.04 and all 32-bit operating systems. As such, OBS will no longer be supported on these platforms.

For more details, please refer to our Discussion Post: Plan to Upgrade OBS Studio to Qt 6.

28.0: Native Apple Silicon Support
With OBS 28, OBS now has native builds for Apple Silicon systems. This means that OBS will run more optimally and without x86 emulation. Unfortunately, an important caveat for this is that many third-party plugins may not yet be readily available for Apple users running native Apple Silicon builds. Users can still use x86 builds of OBS if they desire a wider selection of third-party plugins that are not yet available natively for Apple Silicon.

OBS Studio 25.0.8 Hotfix Changes

Added status icons next to the timers for recording and streaming
Added white icons for dock titles
Added an actual name for files when browsing for LUT files
Fixed media source not closing file when inactive
Fixed certain services not properly updating their server information on Windows
Fixed multiview not rendering correctly on macOS
Fixed a minor memory leak
Removed the requirement for the replay buffer hotkey now that there's a button to record a replay


OBS Studio 25.0.7 Hotfix Changes (macOS)

Fix an issue with text sources on OSX 10.13
Fix an entitlement issue that was breaking plugins
Fix running OBS on macs with case sensitive file systems


OBS Studio 25.0.6 Hotfix Changes (macOS)

Prevent closing vst plugin windows from the window UI for now to avoid a crash. You can still close them from the filter properties.
Make syphon plugin use ARC to fix some memory issues we ran into


OBS Studio 25.0.5 Hotfix Changes (macOS)

Fixed a crash that could occur when using secure input fields on macOS. Because of a likely bug with macOS Catalina that was causing this crash, if you use secure input while using OBS, external hotkeys will no longer function for the duration of the program, so if you use hotkeys with OBS, we do not recommend using secure input while using OBS. (This is a temporary fix to the crash because the only way to fully work around it is likely rewriting the entire macOS hotkey system to a different hotkey-capturing method)

Fixed an issue where performance would be severely impacted when using Studio Mode on macOS


OBS Studio 25.0.4 Hotfix Changes

Added an option to use MixrElixr when using Mixer in the streaming section of settings

OBS Studio 25.0

New Features
Added the ability to capture Vulkan-based games with game capture. Big thanks to Ubisoft Montreal for submitting this feature! [Littlematth/jpark37/Jim]

Added a new capture method to window capture which allows capturing browsers, browser-based windows, and Microsoft Store (UWP) programs [jpark37]

By default, it will use "Automatic", which will use the normal method on most windows, and the new method on browsers, browser-based windows, and Microsoft Store (UWP) programs
The downside of the new method is that it can cause a bit of cursor lag, as well as a highlighted border around the captured window. The border itself does not get captured, however.
You can choose which capture method to use in window capture properties
Added advanced scene collection importing (on the menu bar, Scene Collection -> Import) which allows you to import from other common streaming programs [Dillon]

Added Media source hotkeys to allow control of playback (stop/pause/play/restart) [cg2121]

For now, these are just hotkeys. User interface for this is also planned for future updates
Added the ability to drag and drop URLs to create browser sources (after displaying a confirmation prompt to ensure it was by intention) [WizardCM]

Developers can add an embed to their web pages that let them pre-specify parameters that automatically get set in the source when it's dragged into OBS. See this link for more details: https://obsproject.com/tools/browser-drag-and-drop
Added T-bar to studio mode [cg2121]

Note that this will not work while using a Stinger transition or the "Cut" transition
Added support for the SRT protocol (https://en.wikipedia.org/wiki/Secure_Reliable_Transport) [boxerab]

This is available by choosing "Custom" under Stream settings > Service, then entering your srt:// path into the Server box.
Added a button grid mode to the scenes list, which can be toggled via right-clicking on the scenes list [Dillon]

Added ability to lock volume values of audio sources via their right-click context menu in the mixer [cg2121]

Added source icons to the source list that give a more visible indication of their function (can be disabled in the View menu) [cg2121]

Added support for cube LUT files in the LUT filter [jpark37]

Added an option to show all audio sources to advanced audio settings [exeldro]

Added an option to use percent rather than dB in advanced audio properties via right-clicking items in the window [cg2121]

Added a system tray icon to show when the recording is paused [Programatic]

Added a "Custom Quantization Matrix" option to QSV encoder (available on Ice Lake or newer) [brittneysclark]

Added an option to toggle looping to the scroll filter [Dillon]

Added a "Fade to Black" option for quick transitions in studio mode [cg2121]

Added string specifiers to the Filename Formatting option in advanced settings which allows you to specify certain settings such as resolution and FPS to recording filenames [exeldro]

Added a hotkey to reset the stats window/panel [cg2121]

Added help icons when an property has a tooltip associated with it [WizardCM]

Added monitor names in monitor selection context menus [WizardCM]

Video settings now shows aspect ratio of canvas and output resolutions [cg2121]

Changes/Tweaks
Increased default size of color source to the size of the canvas [cg2121]
Increased default size of text in text sources [cg2121]
Increased the number of files you can open with the image slideshow at once [Jim]
Added various minor performance improvements [jpark37]
The mask filter will now reload the mask automatically if the mask file has been modified [omkelderman]
The browser source now uses a monospace font for the custom CSS property [WizardCM]
Redesigned Decklink output UI by combining the start and stop buttons and highlighting them when the output is active. [cg2121]
Removed the older deprecated NVENC encoder in advanced output mode to prevent confusion. You will now only see "NVENC (new)" (which we will eventually rename back to just "NVENC"). Rescaling is now supported on it (automatically falls back to the older implementation internally)
Bug Fixes

OBS Studio 24.0.6

25.0.6 Hotfix Changes
---------------------

Fixed macOS Catalina issues
Fixed macOS Python scripting support
Fixed a bug where audio bitrate would not be properly set to the specified value in simple output mode
Fixed a bug where videos on loop could sometimes get frozen when switching scenes
Fixed a bug with Linux Display Capture where the crop value would shift the cursor's captured position incorrectly

Fixed an issue where audio monitoring on Windows would have a bit of unintended latency introduced by 24.0.2


OBS Studio 24.0.2

As usual, if you would like to support our project, please check us out on Patreon or OpenCollective!

Changes
Hardware accelerated decoding on the media source is now disabled by default rather than enabled by default. Some users use a ridiculous number of media sources, and turning on hardware accelerated decoding for every single one of them could cause some stability issues.
When running OBS as administrator, games will now be much less likely to cause lag to the video of OBS (we will eventually get this improvement working without requiring administrator, currently this does not work unless OBS is running as administrator)
Fixed an issue where media keys on your keyboard could trigger video/audio to stop/start playing in browser sources
Fixed an issue where part of the OBS output would be green when using OBS from a VM
Fixed an issue where stingers could sometimes cut off prematurely before they were finished
Fixed a freeze that could happen when using NVENC and changing the bitrate while in use while lookahead was enabled
Fixed a bug where OBS could sometimes stop recording due to lack of disk space despite having plenty of disk space
Improved the playback accuracy of media sources and stingers (this was the same issue that caused stingers to sometimes play back a bit erratically)


OBS Studio 24.0.1 Hotfix

Browser sources will now have their pre-24.0 audio behavior by default; to use OBS to control the browser source audio, users must now use the "Control Audio via OBS" option in the browser source properties. This change was made as a safety precaution because it changed user configurations compared with how the browser audio used to function, which confused some users.
Fixed an issue where certain cameras (particularly C920 cameras) would output with a lot of delay depending on the drivers installed
Fixed a crash on startup
Fixed a crash that would happen when closing the Mixer chat window


OBS Studio 24.0

New Features
Added the ability to pause while recording to allow seamless on-the-fly removal of video segments. This can only be used when not sharing an encoder with the stream. [Jim]
Added an option to automatically adjust bitrate when congestion occurs to advanced settings, which is an alternative to dropping frames (available in advanced settings). Note that this currently only works with RTMP, and severe congestion may cause increased delay to viewers. [Jim/pkv]
Added the ability to select multiple sources on the preview by box selection [Dillon]
Added the ability to create custom browser docks in the View -> Docks menu. This allows you to open extra dockable webpages whenever OBS opens [Jim]
Browser sources can now have their volume adjusted via the audio mixer, or have filters applied to them. Additionally, you can now change whether the browser source outputs to speakers or to stream only via the audio monitoring settings in advanced audio properties. [Osiris/pkv/Jim]
Added a script to pause recording when a specific scene is active [cg2121]
Added a "Hotkey Focus Behavior" option to advanced settings, which allows you to set whether hotkeys are disabled depending on whether you have the main window in focus or not [jb-alvarado/Jim]

Fixed a bug where pause would desynchronize audio/video the more often it was used
Fixed a bug where pausing could cause a crash or freeze when pausing/unpausing over and over too quickly
Browser docks now fully shutdown when hidden (prevents playback of any video/audio that may have been playing by browser)
Added an option to browser sources, "Reroute audio through OBS", which is enabled by default. This allows the user to turn off the new browser audio handling if they need to for whatever reason (usually only useful when you need to monitor with a different device than what OBS is set to monitor with)
Release Candidate 2 Fixes
Fixed a bug where browser source audio would cut out with certain stream notifications
Fixed a bug where browser sources would sometimes stop rendering
Fixed an issue where x264 would spam the log every time the bitrate changed when dynamic bitrate was activated

OBS Studio 23.1

New Features/Improvements
Added optional Twitch activity feed panel when account is connected to OBS (hidden by default)
Added Restream.io account integration
Added option to select color range to Linux video device source
Added ability to copy and paste filters from the mixer
Added preview/program labels to studio mode
Added new settings icons
Added a checkbox for bandwidth test mode in settings when using Twitch account integration
Added 25/50 PAL framerate values in video settings
Added "Area" scale filtering for sources as an alternative to point scaling. May preserve more detail on retro games
Added the ability to select video / audio connectors on the Decklink source from inside OBS
Added the ability to swap Front Center and Low frequency effects channel on the Decklink source
Improved the attack/release processing of the expander audio filter
Bug Fixes/Tweaks
Reverted 23.0 changes to slideshow, and instead introduced a 250 megabyte memory limit to image slideshow so people can't accidentally exhaust their memory by loading countless images from a folder. This fixes an issue where large image counts would cause increased CPU usage and rendering lag when transitioning images, or when switching scenes in some cases.
Removed the close buttons from primary docks (scenes, sources, transitions, mixer, controls). These docks can still be hidden, but now must be explicitly hidden with the view menu instead. This change does not apply to secondary docks, such as chat, stream information, or stats.
On Linux, the tray now uses icons from the system theme
Fixed a bug when upmixing from mono to stereo would cause the volume to be quieter
Fixed a bug where NVENC wouldn't show up for the NVIDIA Quadro P5000
Fixed another case where the last frame of an NVENC stream/recording could show up as the first frame in a subsequent stream/recording in the same running session
Fixed another case where output could be green for certain devices
Fixed a crash that could happen if you clicked settings too quickly after starting up with streaming account integration, or if you exit the program too quickly

Auto-remux no longer deletes the old file, just as a safety precaution


OBS Studio 23.0

You can now support OBS development on Patreon and Open Collective. Read our announcement blog post for more details.

Service Integration (Windows)
Added the ability to optionally connect your account to Twitch or Mixer from within OBS (with more services in the works). When your account is connected, you do not have to enter in a stream key, and gain access to special features related to that service, such as a chat panel or stream configuration/statistics panels.
Twitch integration: Added Twitch chat panel (with BTTV/FFZ support), the Twitch "Stream Information" dashboard panel allowing you to change your stream title/game/etc from within OBS, and the Twitch "Stream Stats" dashboard panel which shows statistics such as viewer count (Stream Stats is hidden by default, you can unhide it in the View menu -> Docks submenu).
Mixer integration: Added Mixer chat panel
Panels such as chat panels used with services are dockable; you can dock/undock the windows to customize how you want them to be placed when using OBS.
YouTube, Facebook, and more services are still in the works; more to come soon.
Service integration is currently only available on Windows for now, though Linux and Mac support is planned for a later date.
NVENC and Encoding Improvements (Windows)
A new implementation of NVENC has been added which has improved performance, reducing system and resource impact. To enable, go to Settings, Output Tab, and in Encoder select Hardware (NVENC) New. Note that the new implementation is not available on Windows 7 due to limitations in the operating system; the old implementation will be used instead in that case.

Added new features to the new NVENC implementation:

Psycho-visual Tuning: Enables encoder settings that optimize the use of bitrate for increased perceived visual quality, especially in situations with high motion, at the cost of increased GPU utilization. This increases subjective image quality. Qualitative measurements like PSNR may score lower but video may appear better to human viewers.
Look-ahead: Enables dynamic B-frames. If disabled, the encoder will always use the number of B-frames specified in the 'Max B-frames' setting. If enabled, it will increase visual quality by only using however many B-frames are necessary, up to the maximum, at the cost of increased GPU utilization.
General Changes
Added a Limiter audio filter.
Added an Expander audio filter.
Added VAAPI video encoder on Linux.
Added batch remuxing support to the Remux Recordings dialog.
Added an option to automatically remux recordings to MP4 in Advanced settings.
Added a Decklink output tool to the tools menu. This allows you to output OBS to a Decklink device.
Added an optional Stats dock. This dock is disabled by default; you can enable this dock in the View menu -> Docks submenu.
Added multi-track audio support to FFmpeg output in advanced output settings.
Added an About dialog to the Help menu.
Added a filter (search) option to the Hotkeys section of the settings window.
Added a fourth Mic/Auxiliary audio option in Audio settings.
Added stereo balancing (panning) to the Advanced Audio Properties dialog.
Added an option to change the OBS base/output resolution to the size of a source in the right-click context menu of the source. Only works when no outputs are active.
Added a "deactivate when not showing" option to the Decklink source.
Added an Invert Polarity audio filter.
Added an F2 shortcut to rename sources or scenes when selected.
Added VLC source support to the Instant Replay script.
Added a "What's New" dialog that may pop up on startup in the case of announcements or important news
Fixed a bug where screen reader tools for the visually impaired would not read out the items in the source list box in the main window when selected.
Fixed a bug where fullscreen projectors would always be on top despite that setting being unchecked.
Fixed an issue on windows where window capture would use an abnormal amount of CPU usage when its target window was not available
Fixed a number of race conditions and minor memory leaks, improving overall program stability.
When your mouse cursor is hovering over a source in the preview or in the source list, a light rectangle will show up around it indicating that it can be selected.
When a source is dragged outside of the preview area, there is a new visualization for the unseen area of that source while selected.
Simplified and improved the user experience of the "Stream" page of both the settings and auto-configuration windows.
The source selection rectangle has been improved.
The slideshow source now only loads a maximum of 15 images at a time, and dynamically loads images beyond that count as they cycle. This was done to prevent people who put countless files in the slideshow source from running out of memory.
When in studio mode, you can no longer transition if you're already in the middle of a transition.
Removed a number of internal/uncapturable Microsoft program windows from the game/window capture window lists.
Increased the Instant Replay script retry interval.
Docks are now unlocked by default. You can lock/unlock docks in the View menu -> Docks submenu.

Increased the default size of the Twitch "Stream Stats" panel so that affiliates/partners can see their subscriber count/points
New NVENC settings are no longer exposed to the older version of NVENC (for now)
Added a missing text string for the Remux recordings dialog
The slideshow source now will update when you press OK or Apply on its properties rather than when you modify any setting. This prevents the source from reloading its images on any change.
Removed unused 'help' icons from from the title bar of many various dialogs, both new and old


OBS Studio 23.0 Release Candidate 1

Service Integration (Windows)
Added the ability to connect your account of certain services directly from within OBS (with more services in the works).

When using Intel video adapters with the program, the browser source's hardware acceleration is now disabled by default due to incompatibilities with many Intel integrated video adapters
Removed the "Beta" warning from the Auto-Configuration tool

OBS Studio 22.0.1 Hotfix

Fixed a bug where the browser source wouldn't read local files properly

OBS Studio 22.0

General Changes
Major improvements to the browser source:

Added hardware acceleration to the browser source on Windows for greatly improved performance, reduced resources, and allowing advanced rendering functionality such as WebGL. This reduces CPU usage, reduces RAM usage, and even reduces GPU usage. This option is enabled by default; it can be disabled in the advanced section of settings if needed if there are any unexpected issues.
Updated to Chromium version 68
Refactored the entire plugin and pruned approximately 13,000 lines of code (very satisfying for me in particular)
The browser source now has accurate frame synchronization on Windows
Fixed all memory leaks of the browser source
Added the ability to use web browsers as widgets (which isn't currently exposed much, but will allow a lot more custom functionality later)
Added source grouping, allowing the ability to group multiple sources together as a single transformable group:

To add a group, you can either select a few sources and then right-click and choose "Group Selected Items", or you can create an empty group in the Add menu
You can seamlessly drag and drop items in and out of groups
You can ungroup a group without affecting the group in other scenes by right-clicking the group and choosing "Ungroup"
Groups show their list of sources as a sub-list within the main scene list, which can be collapsed and hidden if desired
Groups can be referenced (shared) between multiple scenes like any other source
Groups can have their own effect filters applied to them
Added the ability to set a custom background color to items within the source list to color-code them for improved organization:

To set the item's background color, right-click the source item within the source list, and go to "Set Color"
You can use a preset selection of colors within the menu, you can choose a custom color, or you can reset it to default
Added a "Vertical Layout" option to the mixer's right-click context menu to make the mixer display vertically rather than horizontally (#1257)

The multiview can now be configured to show up to 24 scenes at once in general settings if desired (#1260)

Added an option to audio settings to allow the user to change the audio meter type: "Sample Peak" and "True Peak" (#1189)

Added secure streaming (RTMPS) support for services that support it, such as Facebook (#1360)

It is now possible to use more than one Intel QSV encoder at once (#1341)

It is now possible to use alt-cropping even on sources that are set to a bounding box transform. This fixes the issue where, for example, alt-cropping would not work after you pressed Ctrl-F on a source. Note that in that case, the rectangle's size will not change, but the contents will realign to the rectangle. (01ac60c)

Windowed projectors are now saved and loaded on shutdown/startup (#1195)

Audio sources within the mixer now always displayed alphabetically (#1242)

Significantly reduced GPU usage when the program is idle (I.E. when the program is not streaming or recording) (45b5291)

Added a confirmation dialog when the user has not added video sources to any scenes, warning them that they are about to stream a blank screen. This ensures that new users do not inadvertently stream without at least first adding some sources. (310c98e)

The program will now default to the NVIDIA GPU when on laptops that have both NVIDIA and Intel integrated adapters. This can still be overridden in the NVIDIA control panel if desired

Bug Fixes
Fixed a bug where videos recorded with certain formats would report that they were 1000 FPS in their metadata when they actually weren't (1f592d1)
Fixed a bug where the active monitoring device wouldn't properly change when switching between profiles (#1258)
Fixed a bug where pasting filters without a destination source selected would cause a crash (b0cd7fe)
Fixed a bug where projectors would close whenever "Always On Top" was toggled (#1207)
Fixed a bug where the recording option "Generate file without space" was not working with the replay buffer (#1276)
Fixed a bug where certain size cursors would appear the incorrect size in Game/Window/Display captures on Windows (#1284)
Fixed a bug where in-program hyperlinks would show up with a bad contrast (dark blue) even in dark themes (e1ab9a0)
Fixed a bug where stream output would stop if a stinger transition had a very late transition point assigned to it (an invalid floating point calculation would be put in to the audio data, which would in turn cause the audio encoder to fail and stop encoding, and thus stream output to stop) (0bd2e23)
Fixed a bug on macOS where VLC would not be found for the VLC source despite VLC being installed (ec366cf)
Fixed a bug on macOS where audio monitoring devices would not show up correctly, and fixed a few minor issues with audio monitoring on macOS (#1318, #1345)
Fixed a bug where Mixer's FTL service would cause a crash on macOS (#1374)
Fixed a bug where the color property (when showing the properties of sources/filters) would not show the actual color the user had set it to (#1305)
Fixed a bug where hotkey labels would not update when sources and transitions are renamed, and could cause the hotkey to not be saved correctly (#1310)
Fixed a bug where creating a new profile with advanced output mode active would not enforce the service's settings (such as keyframe interval) (310c98e)
Fixed a bug where hotkeys for start streaming and stop streaming would disappear when going in/out of studio mode (caceb62)
Fixed a few minor memory leaks (#1287, #1292)

OBS Studio 22.0 Release Candidate 2

Release Candidate 2 Fixes
Fixed a bug where the browser source would always be created on startup despite not showing regardless of whether "shutdown when not showing" is set
Fixed a bug where keyboard interaction didn't work on macOS browser source with Release Candidate 1
Fixed a bug where hotkeys for start streaming and stop streaming would disappear when going in/out of studio mode
Fixed a bug where using "Auto" for the twitch server would cause it to select an incorrect server
Fixed a bug where moving sources that were flipped in to a group would cause them to unflip and displace their position. Moving sources in and out of groups should now preserve their flip correctly.
Fixed a bug where you could not use reset transform, flip horizontal/vertical, rotate, center, fit to screen, stretch to screen, or edit transform on group sub-items
Fixed a bug where group sub-items would not snap correctly
Fixed a bug where it was not possible to select the handles of group sub-items that were in a group that had its transform scaled down
Fixed a hang when using multiview and a scene had "show in multiview" disabled by the user
General Changes

OBS Studio 22.0 Release Candidate 1

General Changes
Added source grouping, allowing the ability to group multiple sources together as a single transformable group:

To add a group, you can select a few sources, then right-click and choose "Group Selected Items", or you can create an empty group in the add menu
Groups show their list of sources as a sub-list within the main scene list, which can be collapsed
Groups can be shared between scenes, and thus can be duplicated or referenced between multiple scenes
Groups and can have their own effect filters applied to them
You can seamlessly drag and drop items in and out of groups, or ungroup seamlessly
Completely reworked the browser source:

Refactored the entire plugin and pruned 13,000 lines of code (very satisfying for me in particular)
Added a hardware acceleration option to the browser source on Windows for greatly improved performance, reduces resources, and allows advanced rendering functionality such as WebGL. This option is enabled by default, but can be disabled in advanced settings.
The browser source now has accurate frame synchronization on Windows
Fixed all memory leaks of the browser source
Added the ability to use web browsers as widgets (which isn't currently exposed much, but will allow a lot more custom functionality later)
Added the ability to set a custom background color to items within the source list to color-code them for improved organization:

To set the item's background color, right-click the source item within the source list, and go to "Set Color"
You can use a preset selection of colors within the menu, or you can choose a custom color
Added a "Vertical Layout" option to the right-click context menu of the mixer to make the mixer display vertically rather than horizontally (#1257)

The multiview can now be configured to show up to 24 scenes at once in general settings if desired (#1260)

Added an option to advanced settings to allow the user to change the audio meter type: "Sample Peak" and "True Peak" (#1189)

Added secure streaming (RTMPS) support for services that support it such as Facebook (#1360)

It is now possible to use more than one Intel QSV encoders at once (#1341)

It is now possible to use alt-cropping even on sources that are set to a bounding box transform. This fixes the issue where, for example, alt-cropping would not work after you pressed Ctrl-F on a source. Note that in that case, the rectangle's size will not change, but the contents will realign to the rectangle. (01ac60c)

Window projectors are now saved and loaded on shutdown/startup (#1195)

Audio sources within the mixer now always displayed alphabetically (#1242)

Significantly reduced GPU usage when the program is idle (I.E. when the program is not streaming or recording) (45b5291)

Added a confirmation dialog when the user has not added video sources, warning them that they are about to stream a blank screen. This ensures that new users do not inadvertently stream without at least first adding some sources. (310c98e)

The program will now default to the NVIDIA GPU when on laptops that have both NVIDIA and Intel integrated adapters

Bug Fixes
Fixed a bug where the active monitoring device wouldn't property change when switching between profiles (#1258)
Fixed a bug where pasting filters without a destination source selected would cause a crash (b0cd7fe)

21.1.2 (Windows hotfix)
Fixed an issue with the new 2018 Windows 10 release (1803) that would cause game capture to perform poorly on Direct3D 9.0c games.
Fixed an issue with the auto-updater not being able to see updates in 21.1


21.1.1 (macOS Release)
Fixed a bug on macOS where if an audio capture device was set to "Default", the device would not change until the program was restarted.


OBS Studio 21.1
General Changes
Updated the Browser source to Chromium 63. This includes many important and critical updates to the Browser backend.

The new Chromium build for the browser source now supports APNG (animated PNG) image files.
Fixed a few bugs and a potential crash on shutdown with the browser source, with more fixes and improvements to come in coming updates.
Fixed a bug where the bit icons in certain donation alerts didn't load properly (fixed with the Chromium update for the browser source).
Dockable windows can now be nested.

Updated the program to use the latest Microsoft development toolchain (Visual Studio 2017) for the Windows version.

Changed log file uploading to hastebin (for now) instead of anonymous github gists due to github removing anonymous gist support.

Fixed an issue where the AMD encoder wouldn't show up for some people since 21.0.

Bug Fixes
Fixed a bug where you could import a scene collection with an already-existing name.
Fixed an issue where a spontaneous rare audio glitch could happen when encoding audio on Windows. This was caused by a Microsoft audio encoder library which was used by default on Windows at bitrates between 96 and 192 kilobits per second; this library has now been replaced.
Fixed a potential crash on startup.
Fixed a few scripting-related crashes.
Fixed a bug where setting a blank replay buffer prefix would reset to the default prefix when the program was restarted.
Fixed a bug where the slideshow source would get stuck on the last image is the slideshow image list was cleared.
Selection rectangles are no longer drawn for audio-only sources.


21.0.3 Hotfix (macOS)
Updated the Qt version to 5.10.1 to fix crashes caused by Qt 5.10 (particularly when opening the filters window)


OBS Studio 21.0.2 macOS Release
Fixed an issue with Qt 5.10 moving the macOS theme to a plugin
Additional packaging to make sure Lua works on macOS
Fixed MP3 audio support in the browser source on macOS


OBS Studio 21.0.1 Hotfix
Fixed a crash with the stinger transition.
Fixed a bug where Hauppauge and Live Gamer Portable devices were not outputting audio/video.
Fixed a lock on startup that could occur depending on how audio ducking was configured.

OBS Studio 21.0.1
Scripting
Added Luajit/Python3 scripting support. Scripting can be accessed via the "Tools" menu -> "Scripts".
Lua is supported via Luajit, which comes with the program. Lua is recommended for high performance scripts, automation, and sources.
Python is available if access to its convenient libraries is desired. On windows, to use Python, Python version 3.6 must be installed separately ("x86-64" version if 64bit OBS Studio, "x86" version if 32bit OBS Studio), and the Python 3.6 install path must be configured in the Python settings tab.
Scripting documentation can be found in the developer documentation: https://obsproject.com/docs/scripting.html
Added an example Lua script: An "Analog Clock" source which draws an analog clock (added like any other source when the script is active)
Added an example Lua script: A "Countdown Timer" script which sets the text of a text source to a countdown timer which counts down when that text source is displayed on stream.
Added an example Lua script: An "Instant Replay" script which automatically save a replay if there's an active replay buffer, and then plays back that replay in a specified media source after that replay has saved.
Added an example Python script: A "URL Text" script which sets the text of a specified text source to the text downloaded from a specified URL every specified interval.
New Audio Features
Added sidechain/ducking support to the compressor filter. This allows the ability to lower the audio level of an audio source based upon how loud another source is. For example, to apply microphone ducking to a desktop audio source, add a compressor filter to the desktop audio source, then select the microphone audio source in the "Sidechain/Ducking Source" property.
Added surround sound audio output support, which allows outputting 2.1, 4.0, 4.1, 5.1, and 7.1 audio to stream/recording. (When using this feature, please also make sure to increase your audio bitrate to support all the channels in output settings. Although some services like Twitch support it, note that certain services such as YouTube may not fully support surround sound streaming, and may not downmix them correctly for stereo viewers)
Added new audio meters to allow the ability to see the audio levels of each audio channel of that source. This allows the ability to know if there are any issues with a specific audio channel (e.g. if just the left or right audio channel is somehow low or muted).
Changed audio meters to behave like peak programme meters. This will make it easier to see if your audio is clipping and set your audio levels correctly. For more information, see: https://obsproject.com/wiki/Understanding-The-Mixer
Added an "Audio Meter Decay Rate" option in audio settings to allow selecting a specific delay rate (fast, medium, slow) for the audio meters if desired.
Added the ability to rename audio sources via right-clicking them in the audio mixer, including desktop and microphone audio capture sources added via audio settings.
New Production and Studio Mode Features
Added a "Multiview" projector (accessible via the View menu), which allows the ability to view the preview/program and up to 8 scenes at the same time. Scenes in the Multiview can be clicked to change the scene (or the preview scene in studio mode). You can blacklist certain scenes from displaying in the multi-view by right-clicking the scene in the scenes list and unchecking "Show in Multiview". You can also change the Multiview's layout style in general settings.
Added an option in general settings that allows you to transition to a scene in studio mode simply by double-clicking on it. This also applies to the multiview projector.
Added separate projectors for both preview and program views in studio mode.
Added a portrait/vertical layout option for studio mode in general settings which makes the preview/program views vertical relative to each other instead of horizontal
Added per-scene transition overriding, which allows you to select a specific transition to use for a specific scene. To use this feature, right-click on the scene in the scene list, and select the transition/duration via the right-click context menu. (This override does not apply to studio mode quick transitions)
Developer Documentation
Spent about a week or so and finally wrote full developer API documentation/reference (useful for both native and script developers), which can be found here: https://obsproject.com/docs
Other General Changes and Fixes
Added a new program theme: Acri.
Changed the default program theme to dark mode for new users.
Changed the text of "Multi-adapter Compatibility" in game capture to "SLI/Crossfire Capture Mode (Slow)". This was changed because the wording "Multi-adapter Compatibility" was a bit vague, and users are not typically aware of the potential performance impact when using the option.
Optimized the preview pane and reduced GPU usage by 2-8% depending on how many sources were in the preview.
The streaming/recording buttons in the main window now highlight while streaming/recording.
Fixed a bug on Windows where desktop audio capture could go slightly out of sync with display/game/window capture on certain audio devices
Fixed an issue where certain Elgato devices would not output audio by default, and would require users to select the audio device manually.
Fixed a bug with studio mode where scenes that are set to fully duplicate would not retain their filters.
Fixed a stuttering bug on Linux with audio monitoring
Fixed MP3 audio support in the browser source on macOS
Fixed a few Dark/Rachni theme issues
Fixed a lot of minor bugs and a few minor memory leaks

Fixed a crash when using certain lossless RGB media files with the new media source


OBS Studio 19.0

General Changes:
Added an auto-configuration wizard to the tools menu and on first-time use, which will attempt to automatically test and configure video/encoding/streaming settings based upon your system and internet connection. This wizard is currently in beta and may be subject to change, feedback is appreciated here: https://obsproject.com/forum/threads/obs-studio-19-0-0-auto-configure-feedback-megathread.68509/
Added a stats dialog to the view menu (with the option to show it on start it up in general settings). The stats dialog shows advanced statistics, such as: average frame rendering time, frames lost due to encoding/rendering/network lag, HDD space left in recording location, and how much data has been output total.
Added a "Render Delay" filter that allows delaying non-async video sources such as display capture or window capture. Note this is only meant for minor sync adjustments (e.g. syncing your screen capture to a webcam), and because the delayed frames are stored on very limited VRAM, the allowable maximum delay is 500 milliseconds (which is 250 megabytes of VRAM on a 1080p 60 FPS source)
Added the ability to copy and paste filters between sources
Added Ctrl-E as a shortcut to edit transform of sources
Added a command line option to start as always on top (--always-on-top)
Added a "shuffle" option to the VLC video source
Added the ability to copy and paste sources (with transforms) from one scene to another
Added specific error messages displayed to the user when fail to connect
Added an option to the blackmagic source that allows you to specify the channel format
Added the ability to project a source, scene, or the preview on to a resizable window in the right-click context menu when right-clicking on sources or the preview
Reworked the media source: media files set to activate when switching to a scene will now immediately start play back when you switch to their scene without requiring time to load
Reworked the media source: media files will now loop properly with no abnormalities in sound playback
Fixed a bug where scenes could be unintentionally lost under specific crash circumstances (backup files were always present, but were not being used -- this is now fixed)
Fixed an issue where the blackmagic source can start up or spontaneously go out of sync
Fixed dragging and dropping text files to create a text source on non-windows systems
Fixed a bug where devices outputting NV12 (e.g. Logitech BRIO cams) would have distorted colors
Fixed a bug where frame dropping would not happen properly when using the ultrafast x264 preset
Fixed a bug from 18.0.2 where "downmix to mono" would no longer save
Fixed a potential crash under specific circumstances when OBS is set to minimize to task tray
When dragging and dropping text files to create a source, those sources will now have the same name as the text file being dropped
All dialogs should now have close buttons (useful on certain window managers such as gnome)
Filter names are now sorted when adding new filters
Windows Changes:
Added an option to disable audio ducking on windows, now on by default. Prevents the system from lowering volume of programs when the mic is activated by OBS
Added HEVC recording support to the AMD encoder
Added Two-Pass and Full-Range color support to the AMD encoder
The AMD Encoder has been completely rewritten from scratch for improved stability, performance and new features. All advanced configurations will break due to this change
The cursor will now be hidden when you are alt-tabbed out of the captured game/window when using window or game capture
Fixed an issue where the device source would activate on startup even when it's in another scene and set to deactivate when not visible
Fixed and clarified window capture prioritization. "Title" will now match any window of the exact window title, "class" will try to find a window by the title otherwise match any window of the same window type, and "exe" will match any window of the same title or if not found any window of the same program.
Fixed a crash when using QSV to encode
Fixed a bug where log files wouldn't be created when the current windows user had unicode characters in the name
Fixed an issue with the AMD encoder which would make it difficult to seek on certain file types
(Repeating 18.0.2 in case it was missed) Fixed poor game capture performance with some DirectX 9 games on the Windows 10 "Creator's Update" as well as some cases Windows 7
Linux Changes:
Added the auto scene switcher to linux
Fixed a potential crash in the settings dialog
Mac Changes:
Fixed an issue where you would not always be able to select all available fonts in the text source


OBS Studio 18.0.2

Hotfix Changes:
Fixed an issue on windows where game capture would have poor capture performance with 32bit DirectX 9 games (primarily Valve games) on the new Windows 10 "Creator's Update", and in some cases Windows 7.
It is now possible to monitor audio from desktop audio capture sources as long as the device you're using to playback the audio monitoring does not match the device of the capture source you're trying to capture (to prevent an audio feedback loop).


18.0.1 Hotfix Changes

Fixed a number of bugs with the "Enable new network code" option in advanced settings on Windows, including high CPU usage, issues reconnecting, and issues with low latency mode not working as intended
Fixed a few potential crashes with the AMD AMF encoder on Windows
Fixed a few issues with VST plugin, such as VST save/load states and a crash when OBS is set to mono
Fixed a bug where the audio monitoring device would always be set to default audio playback device when the program started up
Finally fixed an issue with avermedia LGP and LGP-lite devices used directly with OBS where their audio would not play back correctly (the stream engine should no longer be needed to play back these devices)
The program will no longer fail to start if you use command line parameters that aren't specific to OBS itself (i.e. command line parameters specific to the browser plugin)
Sync offset will now work with audio monitoring on Windows when video is also present on that source


OBS Studio 18.0

Improved program startup time
Fixed a bug when using the QSV encoder where if frames were dropped due to network issues, frames would not stop dropping.
Fixed a crash on startup with some AMD switchable graphics laptops.


OBS Studio 0.16.5

Windows Hotfix Changes:

Fixed a crash that occurs with active window capture sources when the windows 10 AU driver issue occurs and the graphics subsystem rebuilds.


OBS Studio 0.16.4

Windows Hotfix Changes:

Reverted the "Improved UI appearance on high-DPI displays" change because it was apparently making the window far too large on some displays.
Fixed DLL issues with the AMD AMF encoder


OBS Studio 0.16.3

Windows Hotfix Changes:

Added a workaround for a graphics driver issue occurring on Windows 10 Anniversary Update (1607) that would cause the program to appear to freeze and stop streaming/recording.
With this workaround, when the issue occurs, the D3D11 graphics subsystem now fully releases and then rebuilds all Direct3D references (basically restarts the graphics subsystem and reloads all data) to allow the program to continue working rather than freeze/crash.
Note that when it occurs while streaming or recording, a few frames may display as green in the encoded output.
Added support for capturing DirectX 12 games with game capture.
Added an output timer tool to the tools menu which allows you to schedule the stream or recording to stop after a specific amount of time.
Added support for dropping text files on to OBS to create a text source.
Added a splitter to the properties window so you can now adjust the bottom/top panes.
Updated AMD AMF encoder to latest version. The options have been modified to improve ease of use.
Improved UI appearance on high-DPI displays.


OBS Studio 0.16.2 Hotfix Changes:

Added a Gradient feature to the GDI+ text source (not fully localized yet however)
Fixed an NVENC crash that could happen occasionally
Fixed a few minor issues with AMD encoder presets
Once again, fixed a bug where the window's position would reset on startup (hopefully)


OBS Studio 0.16.1 Hotfix Changes:

Fixed a bug where the main window's position/size wouldn't save on exit
Fixed a bug where files under 3 bytes wouldn't be read by text sources
Changed text source file change update interval to one second


OBS Studio 0.16.0

General Changes:

Added a automatic scene switcher via the tools menu on windows/mac (and linux eventually) that can switch scenes based upon what program/window is currently in focus on the system. More features to be added in future versions. On macs, you can only select applications, not windows. Note that you can also use regex to match a window name.
Added a system tray icon, with the ability to control the program via the system tray, and the ability to hide to system tray.
Added the ability to drag and drop image/video files in to the program to create new sources on the fly (note that on windows this may not work properly if the program is running as administrator, the source being dragged from may also need to be run as administrator)
Added an FPS indicator to the status bar, mostly used to diagnose whether a source in the scene is causing rendering to lag.
Added a "b-frames" option to the NVENC encoder, and set the default to 2. Also fixes an issue where b-frames weren't being used by default, which would impact video quality.
Added a front-end API for developers
Fixed an issue where frames wouldn't drop under certain circumstances and become more delayed than expected.
Fixed an issue where the program couldn't connect to certain types of custom servers.
Fixed a bug where NVENC H.264 profile wouldn't be set.
Fixed a bug with the browser source that would cause it to sometimes freeze under certain circumstances (especially changing settings, deleting the source, starting the program, or shutting down the program).
Fixed a bug where URLs wouldn't work with the VLC video source.
Fixed a bug where hidden sources used by the slideshow source would show up in the "existing source" list when adding a new image.
Streams will now always stop after a maximum of 30 seconds regardless of buffering (though buffering should no longer happen)
You can now click "Stopping Stream..." or "Stopping Recording..." to force them to stop if they are stuck in a "stopping" state for whatever reason (typically streaming, caused by buffering such as with the aforementioned frame drop issue)
Windows-specific Changes:

Added an AMD H.264 encoder for AMD video cards on windows (also pre-configured settings available in simple output mode). Note that this plugin should still be considered an early/experimental build; please report issues on the plugin's repository here: https://github.com/Xaymar/OBS-AMD-Advanced-Media-Framework
Added an improved text source with many more features and better drawing language support, and deprecated the old text source. Any lingering text sources you have saved will still use the old source, so if you want to use the new text source you'll have to create a new text source for them. A new text source is also in the works for mac/linux.
Added a tooltip to the "use buffering" property in the video device capture source properties that explains its function.
Game capture should now no longer require a hotfixes every time windows updates and changes D3D9 libraries.
Linux-specific Changes:

Added the ability to specify a custom audio device when using the ALSA audio capture source.
Fixed a design flaw with the pulseaudio capture where the source would have no properties if the device was unplugged since last time the program was opened.


OBS Studio 0.15.4 Hotfix changes (windows):

Fixed a crash in game capture when going from window mode to hotkey mode


OBS Studio 0.15.3

Added a noise suppression audio filter (using speexdsp)
Added "Luma Wipe" transition (by HomeWorld)
Added the ability to lock the preview
Added all supported file types to VLC video source when browsing
Added the ability to add URLs to VLC video source
Added "Bind to IP" network option in advanced settings allowing users to specify which network adapter/address to stream from
Fixed an issue with VLC video source where media with more than two audio channels wouldn't be downmixed to stereo properly
Cleaned up log file readability significantly (still more work to be done, but it's a start)
Limited reconnect timeout (exponential backoff) to 15 minute intervals max. Fixes an issue where reconnect timeout could have intervals of days if it kept reconnecting unattended
Windows-specific Changes:

Once again fixed game capture performance issues with Direct3D 9.0c games on yet another windows 10 update. (In case anyone is wondering why this happens, this has to be done for every time Microsoft modifies D3D9. We may be able to find a better way to do this in the future)
Added game capture hotkey feature. To use, set it to hotkey mode in game capture properties, and set a hotkey for it in the hotkey section of settings like all other hotkeys. There are hotkeys for both capturing a window and for deactivating capture
Fixed a bug where AAC encoded with windows media foundation on windows 8 and above wouldn't play back in certain programs properly
Linux-specific Changes:

Fixed a display issue with projectors on certain window managers
Fixed a bug where studio mode wouldn't display window captures in the program (output) view

Fixed a crash that would happen if you deleted a scene being used as a source in another scene when it automatically switched to that scene after deletion
Fixed a bug where quakelive wouldn't capture properly


OBS Studio 0.15.0

General Changes:

Added an image slideshow source. The image slideshow has an playlist (which you can also add directories to as well), the ability to use different types of transitions, and the ability to randomize the output
Added a VLC video source with playlist support via libVLC. Note that this currently requires VLC to be installed on your computer (on windows, for the architecture you're using OBS with. For example, if you're using 64bit OBS Studio, you need 64bit VLC). libVLC library files will most likely end up being optionally provided by the installer in the future. This plugin works with windows and mac, and should work with linux (though hasn't had as much testing there).
Added "View" menu to allow hiding parts of the user interface (just listbox toolbars, status bar, and transition pane currently)
Added the ability to to set the scaling sampling filter for each item within a scene (point, bilinear, bicubic, and lanczos filtering). Right-click a source within a scene to set the sampling. This allows improving general source scaling quality for each item within a scene if desired (at the cost of additional fillrate).
Added "Scale/Aspect Ratio" filter which can force a specific resolution or aspect ratio on a source (with a specific desired scale sampling filter).
Added an option to automatically start recording when streaming
Added "Hide cursor over projector" option to general settings
Added the ability to delete multiple selected sources
Changed "Crop" filter to "Crop/Pad" filter to allow it to pad in addition to crop.
You can now add other scenes as sources within scenes. Note that it will automatically detect and prevent infinite recursion, you cannot add a scene or source if it causes infinite recursion.
When stopping recording/streaming, it will no longer cut off video at the end. It will now stop in accordance to the timing in which you hit the button. Buttons will now say "stopping stream" or "stopping recording" while waiting for the point in which to stop the stream/recording to ensure it stops at the right timing.
You can now specify directories with the file formatting option in advanced settings.
Increased the maximum delay for the async delay filter to 20 seconds
Whenever an image source gif appears on the stream/recording output, it now restarts the gif from the first frame
Fixed another potential freeze/crash when disconnecting/reconnecting
Fixed NVENC lossless mode, should now work as intended
Fixed a bug where regular lossless codecs and lossless via simple output mode were only using one core
Fixed a bug where the rate control would not be set for x264 under certain circumstances
Windows-Specific Changes:

Fixed a bug where audio output devices wouldn't show up in the video device capture source under certain circumstances
Fixed a bug with game capture where certain blizzard games could crash if the device was lost and reinitialized in the game
Improved game capture capture performance for certain OpenGL games
Added process priority option to advanced settings
Linux-Specific Changes:

Fixed the long-standing crashes with linux window capture
Fixed a bug were window capture would not display window titles with the right text encoding
Mac-Specific Changes:

Fixed an issue with syphon capture only capturing a portion of the target (hopefully)

* Made it so you cannot assign left/right mouse buttons as hotkeys (listen, I know that some people are going to disagree with this, but it's causing some serious problems for new users. They accidentally click the mouse in the box and then don't realize they set a hotkey to their mouse button, and then say "why is this action occuring every time I click my mouse?" ..Please, find a different key/button to use or put it in the ini file manually)

On top of that, reconnecting will no longer stop everything, you will keep recording while reconnecting. Notification also added to the status bar when streaming and/or recording is on/off. (Thanks to the awesome Paibox/Palana duo)
* Because the above required more room, the "Dashboard Link" button has been removed.
* Add NVEnc encoder (Written by BtbN. NOTE: requires nvidia key on non-quadro nvidia video devices)
* More improvements to QSV (Palana)
* Fix mic/device gradual syncing issues, remove "Mic Sync Fix Hack" in advanced because it fixes that problem. This was an issue that mostly happened with mics, the Avermedia Live Gamer Portable, and next-gen consoles (Jim)
* Fix mic removal/disconnection flaw, if your mic gets disconnected it's no longer required to restart the stream, it will automatically reacquire when it's plugged in again. (Jim. FINALLY. Why, Jim, did you take so long with this? This was a serious issue. Why am I referring to myself in the third person? ..Why am I talking to myself?)
* Can now "reset" your mic if necessary in audio settings if for whatever reason the mic audio device needs to be reset, which will cause it to reacquire itself. (Jim)
* Fix a bug with using two push to talk hotkeys, make it so that if both buttons are down, only when the second button is released will it deactivate push to talk. (Jim)
