FFMPEG does not have /arm tree in ffmpeg/libswscale branch. So YUV-RGB conversion takes too much time (20-22 ms for VGA video). This is critical for 40-ms inter-frame intervals (25-fps video). Developers who are competent in NEON can write this procedure using NEON intrinsics. I've tested library written by Robert Watts: yuv2rgb<http://wss.co.uk/pinknoise/yuv2rgb/>. It have C and ASM versions for various video modes and works 2 times faster (for ASM version) than FFMPEG-libswscale but works correctly only in 16-bit RGB output format.
