You're semi-mistaken for the deprecated API:

http://git.videolan.org/?p=ffmpeg.git;a=blob;f=libavcodec/avcodec.h;h=f0ccfee940ae50979132134154fb4380e4bcb05e;hb=HEAD#l1979

It will simply crash on many codecs (e.g. MPEG-based ones) if
these ruels are not followed.

As for the new API, uou are entirely mistaken:

http://git.videolan.org/?p=ffmpeg.git;a=blob;f=libavcodec/avcodec.h;h=f0ccfee940ae50979132134154fb4380e4bcb05e;hb=HEAD#l2102
