Enable assembler for x264 and ffmpeg for x64_86 builds
Please enable assembler optimizations for x264 and ffmpeg when building for x64_86 (they support PIC properly). Understandably this cannot be done for x86 build as these projects do not support PIC with x86 assembler properly.
Basic modification is to add yasm to make depends, and remove the disable-asm configure statement. I’ve measured 100%+ speed difference when re-encoding h264 with ffmpeg.
I would post patch, but I’m unsure how to do this so that x86 gets no-asm and x86_64 gets asm.
