[Libav-user] pass-through "re-containering" with libavXXXX

["René J.V. Bertin"]

Hello list,

Can someone point me to a bare-bones (possibly pseudo-code) implementation using libavformat, libavcodec etc. of a command like

ffmpeg -i somekindofIncomplete.mp4 -vcodec copy wellFormed.m4v

that takes an incomplete mp4 file (that doesn't play back in most players) and repackages the content without transcoding in a well formed m4v container?

Thanks in advance,
René
