[FFmpeg-devel] [PATCH 2/4] avcodec/mips: MSA (MIPS-SIMD-Arch) optimizations for AVC intra prediction functions
shivraj.patil at imgtec.com
shivraj.patil at imgtec.com
Wed Jun 10 16:18:39 CEST 2015
From: Shivraj Patil <shivraj.patil at imgtec.com>
This patch adds MSA (MIPS-SIMD-Arch) optimizations for AVC intra prediction functions in new file h264pred_msa.c
Adds new generic macros (needed for this patch) in libavutil/mips/generic_macros_msa.h
