Nice to see the work for aarch64! We are also in the process of doing NEON optimization for HEVC decoding. (http://ffmpeg.org/pipermail/ffmpeg-devel/2017-October/218233.html <http://ffmpeg.org/pipermail/ffmpeg-devel/2017-October/218233.html>) Now we are just about to finish arm 32-bit work and ready to send some patches out. Looks like for aarch64 we can join force:) What do you think? > > The patch contains optimizations for most heavily used qpel, epel, sao and > idct > functions.
