On a related note, have you considered how the constant qp mode should work? I found this discussion: http://forums.guru3d.com/showpost.php?p=5369519&postcount=10 which noted that x264 sets the I and B frame quantizers to ratios of the P quantizer in crf mode (equivalent to const qp), while nvenc sets all three to the same value. Should nvenc set different values too? Thanks, --phil _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
