Yes, this patch only enhances that parameter. Was more meant in general, as I never fully understood what that parameter does. The constqp rc mode uses the -qp parameter to set its constant quality. This is something different, and from my observation is fully independent, at least I see no difference when setting this parameter in constqp mode. _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
