Um I beg to differ. I have an mp4 container with pcm-s24be and it plays
beautifully. However, it was done with a piece of software for Windows.
While it uses ffmpeg and almost all of the codecs; I have no way of seeing
what and how it is going about this. 

So, I know it can be done. The question is how.

Stop asking me for the file. I cannot give it to you. It is a commercial and
is copyright protected. Not a fan of getting sued. It is the only one I have
where ProRes was used in the post.

Look, in all honesty, I have asked for help on this list a number of times.
Not once have I been given a working solution. The documentation for ffmpeg
is sparse at best. 

Can any of you point me in the direction of good books to learn ffmpeg?
