Hi Michael, Here is a totally shot in a dark fix attempt for NEON register clobbering for deblocking. Could you test it with qemu and check if it works.

If they cant, then i probably can test it too if its a patch which applies cleanly to ffmpeg and testing fate-hevc with --enable-neon-clobber-test under qemu is what is needed i could test on a arm board too if needed > > I also have SAO, qpel and epel NEON patches for latest FFmpeg.
