Does this work on Pro Logic-encoded files (ticket #4085) or does this filter use a different algorithm? Does a filter have advantages over an implementation in libswresample? Iirc, our Pro Logic downmixer has an issue with "phase shift" (ticket 3455 / 4175): Does this filter give expected output for FFmpeg-encoded files or original Pro Logic files (or is there no difference on upmixing)? Thank you, I believe this is a very important feature, Carl Eugen _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
