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.	10 years ago
