Video/audio command line converter.
 
https://ffmpeg.org/ does the source code. They list a couple compilation sites, of the two this one was easier to understand: https://www.gyan.dev/ffmpeg/builds/
 
I needed to be able to extract my 24-bit PCM audio from my hybrid mp4s out of OBS, because LosslessCut is tripping on the audio in that combination. So I can extract the audio with Ffmpeg like
 
ffmpeg -i mobed.mp4 -c:a copy mobed2.wav
 
then put add audio in LosslessCut as a new track, disabling the original audio track, and then LosslessCut is okay.
 
So great. Although hopefully LosslessCut will just get it sorted at some point. 'p'

I made a .bat file in the Ffmpeg bin directory--where ffmpeg.exe is--to do the audio extract for any mp4 placed there:
 
for /r %%i in (*.mp4) do ffmpeg -i "%%i" -c:a copy "%%~ni.wav"
