Blending testsrc and testsrc2 at hd720 yuv420p I get ~81fps using my addition. Using lut2 I get ~80 fps. Using no filters and rendering just those 2 source I get 103 fps. That is without SIMD though. With SIMD I would expect blend to win. I'm actually surprised that evaluating the expression isn't dead slow. _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
