I can't bench on anything but x86, which is why i sent this patch to get other people's opinions. You tried other 32 bit architectures like arm7 or PPC? fast_64 is a configure time constant used in a lot of speed critical modules to choose between using 32bit or 64bit ops, so seeing how this new bitstream reader uses a 64bit cache I'd expect it to be slower in such targets as well. _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
