[FFmpeg-devel] [PATCH 1/2] swscale: rgb_to_yuv neon optimizations

[Dmitriy Kovalenko]

All the comments were addressed, except the prefetch one in the patch version 2 I sent earlier today. And how did you test the prefetch, because I literally run a native benchmarking on the device right now and I see that with the patch applied I am getting 5% of performance improvement. Maybe there is an issue in the way you measure the timers? I can for sure remove them because I anyway use my own implementation that is 5-10x faster than the ffmpeg's, but I am genuinely curious how is it possible that you see different benchmarking results.
