Mickaël Raulet	6ecc3fd612	x86/hevc_mc: use aligned loads Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Christophe Gisquet	52f2adc015	avcodec/hevc: Update the USE_SAO_SMALL_BUFFER case for the alignment requirements in FFmpeg Use edge emu buffers And enable the code unconditionally Speed difference without USE_SAO_SMALL_BUFFER and with the new code: Decicycles: 26772->26220 (BO32), 83803->80942 (BO64) 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.
