Tried to install on Linux Mint 19.3, and got following message:
Error: Dependency is not satisfiable: libavcodec-ffmpeg56(>=7:2.4) | libavcodec-ffmpeg-extra56(>=7:2.4).
I got a similar error trying to install an older version some time ago, and it was a pain in the butt trying to locate these files for installation, so much so, that it is not worth the trouble. If you produce software and claim it works under Linux, why don't you have the sense to check it, and ensure that dependencies are met, instead of wasting other peoples time?

Tha 64-bit build od MP4Box requires the files 'libeay32.dll' and 'ssleay32.dll'. Which is weird, IMNSHO — from what I have read thus far, these two files are OpenSSL stuff, and I see no point in making an MP4 multiplexer depend on SSL functions...
