How to edit MKV data without remuxing (change default audio, rename lang)

[spycam]

Well, i would like just to edit language codes of the audio streams, as they all seem to be marked as ENG but they are different languages, also, i would like to set which audio stream is the default one to play when MKV is set to play.

Is it possible to make that without remuxing the whole video? I'm talking about large MKV files of 20 Gb and more.

What software could i use for that?

"mkvpropedit -- Modify properties of existing Matroska(tm) files without a complete remux"


You can try jmkvpropedit, a GUI for mkvpropedit

OK, that worked, but there is another problem i found.
The MKV files muxed with mkvmerge are better as the ones muxed with AVIMux-GUI have problems with seeking when watching them on VLC.
Is there a way to fix that without remuxing as well? What tool?

Just remux it with MKV Toolkit....

remuxing take only a couple of seconds anyway

Remuxing 10 MKVs of 20gb each does not take seconds

[teodz1984]

1. Run mplayer with -forceidx:
mplayer -forceidx myfile.mkv

-forceidx
Force index rebuilding. Useful for files with broken index (A/V
desync, etc). This will enable seeking in files where seeking
was not possible. You can fix the index permanently with MEn-
coder (see the documentation)


2. re-create the container with FFmpeg with something like:

ffmpeg -i myfile.mkv -acodec copy -vcodec copy my_newfile.mkv

Do a batch merge with mkvmerge,add to job queue and manage jobs and start.

The things you offer do full remuxing of the MKVs with the need of creating new files.

What i was asking about was to fix MKV files without remuxing to new files

[teodz1984]

If you complain that h AVIMux-GUI did a botched job remuxing MKVs the ONLY FIX is the remux them with MKVToolkit......
Something about indexes or cues not properly created....

Sometimes even problematic MKVs made with old unstable versions of MKVtoolkit can be fixed by a remux....

What i was asking about was to fix MKV files without remuxing to new files
Aside form MKVProp edit which is part of MKVToolkit.... I don't see anythinng else

Unless you want to program one for your needs.

Also try another media player like KMPlayer or Potplayer who do a better job playing MKVs than VLC

spycam ,
If you are so lazy not to do the quick fixes given above... then learn to just live with your quirky MKVs....
Just play them and don't seek them while playing....

The latest versions of MKVToolNix (8.x) contain a new mkvtoolnix-gui application which includes a full header editing interface
