I don't think it is reasonable for all of this to be public API surface of ffmpeg.

A separate library containing the headers and exposing some set of functions like this might make more sense.

If this has to be in ffmpeg then it really needs to all go in one library (libavcodec I guess) so that it's not exposing all this internal detail in the public API.

Thanks,
