mkvmerge,mp4box - wrong fps, tsMuxer-right

cybpsy · 18th May 2009, 02:49

Hello!

I have demuxed video from blu-ray using eac3to 3.16.

I've got this record in log about it:

Code:

M2TS, 3 video tracks, 11 audio tracks, 28 subtitle tracks, 1:52:14, 24p /1.001
1: Chapters, 20 chapters
2: h264/AVC, 1080p24 /1.001 (16:9)

Next I try to remux it with audio (from this BD) to mkv using mkvmerge 2.8.0 (I've also tried 2.7.0) but I get file of length 1:52:24 and audio is out of sync in it. Audio has correct length of 1:52:14, video before muxing also is 1:52:14 (dgavcindex+avcsource in avisynth script), but after muxing when I set fps to 24000/1001 I get 1:52:24. I've also tried to mux video to mp4 using mp4box - result is the same. But when I use tsMuxer and m2ts format - everything is OK

I have even tried to set fps exactly as number of frames of my video divided to 6734 (number of seconds), but I've failed and got 1:52:24 video after muxing. Please anybody help me with this problem.

I've found the answer. I should demux to mkv using eac3to, not raw avc.
