[FFmpeg-devel] [PATCH v2] avcodec/mips: [loongson] optimize memset in h264dsp.

2018-08-30 Thread Shiyou Yin

Optimized memset with mmi in following functions: 1. ff_h264_add_pixels4_8_mmi. 2. ff_h264_idct_add_8_mmi. 3. ff_h264_idct8_add_8_mmi. This optimization improved h264 decoding performance about 1fps(tested on loongson 3A3000). Change-Id: I4e8b75510e6a34b4c80f84ad784b00377570c4ec --- libavcodec/
