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 <https://www.ffmpeg.org/fate.html>

You can also use checkasm to benchmark your arm64 neon codes. For example ‘checkasm —test=hevc_sao —bench’ to test sao function performance.

You should also split your pathch into smaller one. For example patch about sao mc and idct. Every patch should tell us speed-up ratio by using checkasm.
