Hi, How can I get FFmpeg to detect and use ARM Neon code at runtime?
Problem: If I compile with -mfpu=neon then FFmpeg blows up with SIGILL (ILLOPTPC) when run on a non-Neon CPU. If I compile with -mfpu=vfvp3 then FFmpeg runs fine, but presumably without the optimized code because this is what I currently have and I am getting performance complaints... Would it be possible for FFmpeg to detect Neon at runtime? This is for Android and the Android NDK does includes a demo project that shows how to do CPU feature detection at runtime... that's the easy bit. I don't know how or where to begin updating FFmpeg to use it. Thanks, Reuben
