You could also learn to use mkvextract from the command line. It's not that hard.

It's not hard, I'm used to command lines at home and work, but it's a pain in the butt as I have a lot of files to process. I'm going through my video archive to re-encode the AC3/DTS/etc. tracks to put them on my networked media tank using a different audio format (AAC).

End users having to do anything in the command line in 2012 bewilders me. Should be totally unnecessary. I know this is a "power user" program (and a great one at that) but still, GUIs are so much easier to use.

In theory, this'd be fixed pretty quickly. However, AFAIK, none of the three main GUIs (MKVExtract GUI, MKVExtractGUI-2, MKV Cleaver) have been updated in ages (years even)!

As a tip: eac3to makes it unnecessary to demux the audio tracks, as it can work directly on mkv files.

@Boulder,
You can process many files by using a for loop. Just open a command window and type "for /?" to get the syntax. You can also Google for more clarification and examples. Once you set up your batch/command file to do what you want, it just requires minimal after that. If you're more comfortable with a language like Visual Basic, you can always use Windows Host Scripting. Whatever tool you decide to use, if it has a CLI then you're good to go.

Here's an example for you that uses the MediaInfo CLI to display and log some basic info about, in this case, TS files found in the folder where this file is executed:
Code:
@echo off
setlocal EnableDelayedExpansion
set SEARCH=*.ts
set LOGFILE=MEDIAINFO.LOG.TXT
set vformat=
set vscantype=
set vscanorder=
set vfps=
if exist "%logfile%" del "%logfile%"
for /f "delims=" %%i in ('dir /b "%SEARCH%"') do (
	set vformat=
	set vscantype=
	set vscanorder=
	set vfps=
	echo PROCESSING %%i
	echo PROCESSING %%i >> %LOGFILE%
	rem GET video format
	for /f "delims=" %%f in ('mediainfo --Inform^=Video^;%%Format%% "%%i"') do (
		set vformat=%%f
	)
	for /f "delims=" %%s in ('mediainfo --Inform^=Video^;%%ScanType%% "%%i"') do (
		set vscantype=%%s
	)
	for /f "delims=" %%s in ('mediainfo --Inform^=Video^;%%ScanOrder%% "%%i"') do (
		set vscanorder=%%s
	)
	for /f "delims=" %%f in ('mediainfo --Inform^=Video^;%%FrameRate%% "%%i"') do (
		set vfps=%%f
	)
	echo Format: !vformat!, Scan Type: !vscantype!, Scan Order: !vscanorder!, FPS: !vfps!
	echo Format: !vformat!, Scan Type: !vscantype!, Scan Order: !vscanorder!, FPS: !vfps! >> %LOGFILE%
)
:end
endlocal

Thanks, I may not need it for this particular job but I got something else that such approach would benefit

Good news, everyone! The author of MKVExtractGUI2 has just posted on my bug tracker that he's updated his GUI:

I was holding off on doing anything until there was news of anything updating.

I figured it would be a week or so lol.

Thanks for the info.

Don't post this HERE. The author doesn't read the thread. And I don't support any of the mkvextract GUIs as they're not my products.

Got a small (?) feature request for mkvmerge&mkvextract: add the possibility to cut 'from-to' where from and to can be times or chapters.

It's a bit like the splitting by timecodes option.
When using mkvmerge to split by timecodes and feeding it with something like 01:20:10.000,01:23:12.400 I would end up with 3 files (middle one is the one I want) since mkvmerge would create one from 00:00:00.000 to 00:20:10.000, one from 00:20:10.000 to 01:23:12.400 (start chapter 11) and one that goes from 01:23:12.400 (start chapter 12) to the end of the clip.
I know I could abort mkvmerge after the file I want is created (to avoid the last file to be created), but the first file will still be created, which is a pain if the source file is long&large,...

Yeah yeah, has often been requested, will be implemented sometime this decade. Implementing stuff like that is a pain, too.

No hurry, I just stumbled over this scenario a few times in the last few days.
(will probably request it again, when enough time has elapsed and I run into the scenario again )

There's also a bug report for such a feature request already: https://www.bunkus.org/bugzilla/show_bug.cgi?id=518

Oh, didn't know that. I didn't look in the bugzilla since it's not really a bug but more a missing feature in my eyes.

Oh it certainly is, but I also use Bugzilla for tracking feature requests.

Just wondering,.. If I have a bunch of mkv files with multiple audio and video streams in them, and I want to check if one or more of these streams was 'streched' to be synch, how do I do that? (ideally get the strech factor)
Is there some indication, about the streching in a mediainfo, mkvmerge, mkvinfo output I overlook atm., or is the only may to extract, remux and see which streams are asynch after the remux?
(another way maybe to extract the time codes for each track and compare them,..)
