Mans? ...Rich? etc :) ) I agree. The problem right now is that avcodecgetcontextdefaults() doesn't know which codec the context is intended for. I suggest we create a new avcodecgetcontextdefaults2(), or whatever, taking an AVCodec as an argument, and doing the same as the present avcodecgetcontextdefaults, then fetching overrides from the codec. The per-codec defaults could be supplied either by means of a pointer to a function that when called filled in various values, or perhaps somehow using the AVOption stuff. Is this a bad idea for some reason I haven't thought of?

the idea sounds good, so if noone has a better one, feel free to implement that ...
