ffmpeg | branch: master | Shivraj Patil <shivraj.patil at imgtec.com> | Tue Jun 9 21:08:26 2015 +0530| [271195f85bbce284ac80ed31c62fba9b7e74e99d] | committer: Michael Niedermayer
avcodec/mips: MSA (MIPS-SIMD-Arch) optimizations for HEVC loop filter and sao functions
This patch adds MSA (MIPS-SIMD-Arch) optimizations for HEVC loop filter and sao functions in new file hevc_lpf_sao_msa.c
Adds new generic macros (needed for this patch) in libavutil/mips/generic_macros_msa.h
In this patch, in comparision with previous patch, duplicated c functions are removed.
