Re: [FFmpeg-devel] [PATCH] 8-bit hevc decoding optimization on aarch64 with neon

Hi Rafal, It’s very nice to see your work on hevc arm64 neon optimization. You should test if your codes can pass FATE firstly. The main purpose is to test if your codes can pass all hevc-conformance bitstream. About fate please refer to https://www.ffmpeg.org/fate.html
