Of course they have to. But a library is there to help programming
applications, not to act as a dictator or a spoiled brat, and therefore the
API requirements should be reasonable and practical.

Now, let me state it clearly:

lavc should be usable to decode (up to a timestamp on the decoded frame)
MPEG-4 or H.264 with B-frames coming from an AVI decoded by a lightweight

If you do not share this principle, I guess we should simply agree to
disagree and stop there.

Well, I sincerely think I can not be blamed for the API divergence.

By the way, is someone working on removing guess_correct_pts from ffmpeg and
ffplay? That would be coherent with the rest of the discourse.
