Hi, I have quite a few mkv files with audio out of sync when storing xvid to native mpeg-4 asp. The weird thing is all of these files play perfectly fine in mkv with vfw hack. So basically, is there a way to revert back the changes? If not, can you make it available in the next release? Cause I don't like going thru every single one of them to fix synchronization when they are originally in sync prior to muxing. You know, kind of like how you reintroduced the "--engage allow_avc_in_vfw_mode" hack, make a similar feature like "--engage allow_asp_in_vfw_mode" hack or "--unengage native_mpeg-4" ...well something to that effect. The crappy thing is I don't have the original a/v files prior to muxing in mkv nor do I like the fact of going thru the whole encoding process again.

btw, for playback, I use MPC (internal filters disabled) + ffdshow + Haali's splitter.

I found out that the file is ogm/ogg with renamed to avi extension.
However, I think the 0x674f is code OGG. Why the mmg said the audio track unknown? I have another ogm file that the mmg can detect the audio track as vorbis.

Real OGM files with properly muxed Vorbis tracks are fully supported. AVI with OGG/Vorbis inside are not supported, and will not be supported. OGM files which use the ACM mode of storing audio (the same mode that you can store MP3 in OGM) for Vorbis are the same case as AVI with Vorbis -- no, they're even worse. And won't be supported either.

That's mean the 0x674f is the ID of OGG for ACM mode?

Since these brain-dead files can't be that common, why not just use vdubmod or avimux gui to extract the audio track? You'll have to unencapsulate it then (probably by just deleting the header) and it should work after that.

If a stretch AND a delay is applied on a sub track, which one is first applied ?

I am having trouble importing SRT files created by Pelican9's Supread.exe tool - is there something that needs to be added to the SRT file to make it recognizable by mkvmerge?

It starts and ends like this:

Code:
1
0:01:48.041 --> 0:01:50.442
Bloody kids.

2
0:02:36.890 --> 0:02:40.554
How fastidious you've become,
Wormtail.

...

1508
2:23:00.772 --> 2:23:04.538
-Harry will, won't you?
-Yeah. Every week.

1509
2:37:01.345 --> 2:37:03.336
[ENGLlSH]
Thanks.

The timestamps have to use "," as the decimal separator, not ".".

Edit: Or you could just use this build: http://www.bunkus.org/videotools/mkv...20070316-1.rar

If you mean the two components of the --sync switch: First the delay, then the stretch factor. The --delay argument is added last.

No, not yet. I'll post when I know more, but that won't be for a couple of days.

I don't know if this has been already reported, but I have trouble merging a 3 part files that has been previously split using mkvmerge with the "link" options.

The file here is a matroska with MPEG2 + 2 AC3 audio tracks
Once the first file has been processed, I get a:

Negative timecodes? Oh oh... Looks like mkvmerge has overflow issues somewhere. Can you give me some more details about the file? Like duration, how you created it etc.

If I rememeber correctly the files were created using mkvmerge with elementary streams. The MPEG2 stream has been extracted from a Bluray Disk using the xport tool. The movie is 1:30 minutes and spans around three 4.5Gb Files.
Note I have managed to merge them using Haali filter and Haali matroska filter so it seems the files are not corrupted.

I hope this helps

Well, partially. In your case there were no negative timecodes involved, even though the error message is the same. Therefore the reason may or may not be the same.

Is there a way to stretch, THEN delay, via command line ?
