Michael Niedermayer	12c3e120fe	avcodec/ituh263dec: Use 0xffff as error code in h263p_decode_umotion() This matches ff_h263_decode_motion() both functions error codes are interpreted by the same common code Fixes: 690/clusterfuzz-testcase-4744944981901312 Found-by: continuous fuzzing process https://github.com/google/oss-fuzz/tree/master/targets/ffmpeg Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	8 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.	10 years ago
