Michael Niedermayer	0e7444f6e4	avcodec/hevc: Remove current_sps The variable should not be needed anymore Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
James Almer	ba625dd8a1	avcodec: use av_mod_uintp2() where useful Reviewed-by: Michael Niedermayer <michaelni@gmx.at> Signed-off-by: James Almer <jamrial@gmail.com>	10 years ago
Anton Khirnov	7693ba0a0e	hevc: export stream parameters from extradata This allows the callers to have a hint of the probable stream parameters without actually decoding anything.	10 years ago
Anton Khirnov	1ae7afd256	hevc: split out setting AVCodecContext parameters Additionally always set the software pixel format, so it's available even if ff_get_format() is not called later. This will be useful for exporting stream parameters from init().	10 years ago

Peter Meerwald	eea769df32	hevc: Use generic av_clip function, not C implementation hevc seems to be the only place where the C implementation of the av_clip function is explicitly selected, precluding platform-specific optimizations Signed-off-by: Peter Meerwald <pmeerw@pmeerw.net> Signed-off-by: Anton Khirnov <anton@khirnov.net>	10 years ago

Christophe Gisquet	9a2f5d825a	hevc: free sao buffers when receiving a new SPS The buffer pointers would be otherwise overwritten, causing a leak on e.g. PERSIST_RPARAM_A_RExt_Sony_1. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago

Christophe Gisquet	00fe77855b	avcodec/hevc: Do not zero is_pcm on allocation Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Fabrice Bellard	da81cc38e8	avcodec/hevc: reduce memory for SAO cherry picked from commit 5d9f79edef2c11b915bdac3a025b59a32082f409 SAO edge filter uses pre-SAO pixel data on the left and top of the ctb, so this data must be kept available. This was done previously by having 2 copies of the frame, one before and one after SAO. This commit reduces the storage to just that, instead of the previous whole frame.

Changjiang Wei	6f2068e626	avcodec/hevc.c: for big negative mvy value, should wait line 0 of ref frame due to edge extending Reviewed-by: Mickaël Raulet <mraulet@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 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
