Michael Niedermayer	09450c5509	avcodec/h264: fix time_base and framerate They are not just inverses of each other. This should restore behavior to before the introduction of framerate Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Anton Khirnov	7ea1b3472a	lavc: deprecate the use of AVCodecContext.time_base for decoding When decoding, this field holds the inverse of the framerate that can be written in the headers for some codecs. Using a field called 'time_base' for this is very misleading, as there are no timestamps associated with it. Furthermore, this field is used for a very different purpose during encoding. Add a new field, called 'framerate', to replace the use of time_base for decoding.	11 years ago

Christophe Gisquet	585047bb7d	h264: do not return on sidedata allocation failure Not having allocated it is not a good reason to leave the object in an undetermined state.
