Hi Paul,Thanks for the report. Now I know why abel.debian.org or qemu-user-static doesn't reproduce the bug. It is because your environment supports "neon" and ffmpeg will use that for acceleration.
But abel and qemu-user-static doesn't support neon. I think if you "cat /proc/cpuinfo" and neon will be in the Features.
I'll see if I can use cpuflags in ffmpeg to disable neon on my test. So that it can pass.
