I have a few question about mplex related to audio offsets.
1) It appears that I have to invert the sign of the offset with mplex. For example, if I have a mpeg with an audio offset of 118ms, I have to use -118ms in mplex. For other applications like avisynth and virtualdub, I specify 118ms. Why is mplex backwards? 2) After muxing a video with mplex, I decided to check the offset with dvd2avi and pvastrumento. I get very different offsets. If I specify -118ms for a file, dvd2avi tells me the offset is 17ms. Using bbinfo, I got the following for the first video and audio packs: video PTS: 244ms video DTS: 144ms audio PTS: 262ms The same video, muxed with bbmpeg gives the following: video PTS: 280ms video DTS: 180ms audio PTS: 398ms and dvd2avi and pvastrumento report the correct audio offset of 118ms. There are some more examples in this thread on doom9.org http://forum.doom9.org/showthread.php?s=&threadid=63484 Does anybody know why mplex is behaving this way? Is this something to be concerned about? ------------------------------------------------------- This SF.net email is sponsored by: SF.net Giveback Program.
