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
Reimar Döffinger	e8d0b84e8a	h261dec, ituh263dec: Move condition. Stops compiler from doing incredibly stupid things. With vsynth1-flv inner loop goes from 3501 to 3275 decicycles. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	10 years ago

Reimar Döffinger	2a00812d82	h261dec, ituh263dec: Avoid unnecessary -1 inside inner loop. 3646 -> 3597 decicycles in inner loop when decoding vsynth1-flv. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	10 years ago
Reimar Döffinger	935453102b	ituh263dec: Optimize new RL_VLC based decoding. Together with the switch to RL_VLC this results in a speedup of about 30% in this inner loop. Overall speedup only relevant for medium to high bitrate streams. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	10 years ago

Ronald S. Bultje	17fad33f81	Change all uses of restrict to use av_restrict instead. Defining restrict results - for some compilers - in changing other uses of the restrict keyword also, e.g. __declspec(restrict) gets changed to __declspec(__restrict) on MSVC. This causes compilation failures. Therefore, using a private namespace macro instead is more reliable and robust. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
