Batch demux and remux of mkv?

[jp80]

Hi,

I wish to demux and remux a lot of video in mkv to change the default language and subs settings so that japanese dub and english sub is chosen on play.
The problem is it takes a lot of time to do it manually, so I wonder if there is a way to do it automatically, even only by remuxing from demuxed video and audio files?

Run mmg.exe, open the first file, set it up to do with you want it to and copy the command line
From there you should be able to modify the command line to run mkvmerge.exe on each file in a DOS batch file

tx for your answer, it lead me to discover you could use job queue in mmg which is what I needed!

Well I just tried the output files after having set the default audio and subs I wanted for their jobs in the queue, but when I played them they were still the same as before :( ...

Well you could use something like:
for %%f in (*.mkv) DO (mkvextract.exe tracks "%%f" 1:"%%~nf.avi" 3:"%%~nf.ogg" 4:"%%~nf.srt")
to extract and then a similar line to remux, or something like the above directly with mmg and the mkv file.

No need to use mkvextract. mkvmerge can read directly from Matroska files.

Exactly why I said or something like the above directly with mmg and the mkv file. Just going by the title that said demux and then remux.
