gMKVExtractGUI

[gpower2]

As a personal bet, I developed a small GUI utility to use mkvinfo and mkvextract cli tools from MKVToolnix pack, in order to extract tracks, chapters and CUE sheets from mkv files.

Though there are already other GUI utilities, I found them rather slow (original MkvExtract GUI), or inefficient (MkvExtractGUI-2 does not extract attachment tracks correctly).

So, gMKVExtractGUI was born, written in pure C# .NET v2 (.NET v4 since v1.9.0) and it works!

Current version is v2.12.0 and you can always find the latest executable file here:

https://github.com/Gpower2/gMKVExtractGUI/releases

Note: After version v2.9.0, I switched from SourceForge to Github, and all new versions will be released there henceforth.

Buy me a beer

From v1.6.4 Linux is fully supported through MONO framework.
For use with MKVToolNix v9.0.0 and later, v1.7.0 or newer is required.
From MKVToolNix v9.6.0 and later, the JSON output from mkvmerge is used, so Newtonsoft.Json.dll is required (bundled).
From v1.9.0 .NET Framework v4 is required.
Batch support is supported from v2.0.0.
Dark mode is supported from v2.8.0.

Key features:

• Use almost 100% of mkvextract functionality (supports extraction of tracks, attachments, chapters in XML, OGM and CUE, timecodes, tags and CUE sheet)
• Use mkvinfo to analyse mkv elements really really fast
• Automatically detects MKVToolnix installation directory from registry
• It doesn't require the executable to be placed inside MKVToolnix directory, but it still checks for it if registry search fails
• Uses file extensions for tracks according to CODEC_ID as defined in official mkvextract documentation
• Uses separate thread for invoking mkvextract in order to have a responsive GUI
• It incorporates a job mode for batch extracting (new in v1.6)
• Supports Linux through MONO (new in v1.6.4)
• Supports all MKVToolnix versions from v4.x and newer
• Supports batch extraction of multiple files (new in v2.0.0)
• Supports custom output filename patterns (new in v2.5.0)
• Supports adding sub-directories in the custom output filename patterns (new in v2.7.0)
• Supports dark mode (new in v2.8.0)

Hope you enjoy this little utility and feedback is always appreciated!

[wanezhiling]

can't remember settings.

[wanezhiling]

I tested all my mkv files, empty in the list.

[gpower2]

What version of MkvToolnix do you use?
Did you get any error message when you selected the video file?

[wanezhiling]

offical 6.7.0 installer
No error, just empty.

[gpower2]

It seems that mkvinfo didn't spit out anything about the file.
It is really strange since I made most of my tests with 6.7.0 and didn't have any problems.

Did you extract both exe and dll files?
I'll build a version with debug information and upload it in the afternoon to check this, thanks for your feedback!

[wanezhiling]

Of course.

[Taurus]

Same here as in wanezhiling post ->empty list

Edit: Tried it on Win XP 32bit and on Win7 64bit -> the same.

[gpower2]

I just tested it again and I didn't have any problems here:



I'll upload the new version as soon as I can to see what's happening with you guys...

[sneaker_ger]

Could it be a problem with non-English versions of Windows? May want to look into --command-line-charset and/or --output-charset then.

[gpower2]

Perhaps the --ui-language could be the solution, I am working on adding a log form in order to see the true output of the operations.
Won't be long now.

@sneaker_ger
Did you try it yourself? Did you run into any problems?

[sneaker_ger]

Ah, yes, I forgot the --ui-language option. Yes, I tested it on a non-English Windows with the same symptoms as the other reporters.

Also: does it only check file extension? Then .mka, .mks, .mk3d and .webm are missing. (Though I don't think file extensions are a good way to check.)

[gpower2]

New version v1.2 is out, hoping to solve the problems you all had.
In case the problems persist, you can view the log and paste it here in order to examine the root cause of the problems.

Have it a try and thanks again for all the feedback!

[mastrboy]

Are you going to add batch (multiple files) support, similar to MKVCleaver?

[gpower2]

I'm surely considering it, I just haven't figured out yet how to implement the workflow of the batch. I'm thinking more of a job manager thingy, but it would be some time before it gets out...

[wanezhiling]

Funny, it only works with mkvtoolnix 6.7.0, an error occurs with old versions, 6.6.0 eg

[gpower2]

Probably some option is incompatible with older versions, I'll check it and come back with a fix (hopefully).

At least it works with 6.7.0 now, right?

@mastrboy
Any thoughts on the batch processing mode? It would be nice to have some feedback from users first.

[[ReX]]

You should probably use mkvmerge with "--identify-for-mmg" instead of mkvinfo.

Here's a scenario where mkvinfo fails:
1) Take a MKV file (file.mkv) with attachments (fonts, for instance)
2) Check if the output of mkvinfo shows attachments (yes)
3) Add a font attachment to it using mkvpropedit

mkvpropedit "file.mkv" --attachment-name "arial.ttf" --attachment-mime-type "application/x-truetype-font" --add-attachment "C:\Windows\Fonts\arial.ttf"

4) Check if the output of mkvinfo shows attachments (no)

[gpower2]

Hmm, I never thought of checking mkvmerge for command line parameters to identify mkv properties!
Still, isn't that a limitation/bug on mkvinfo's side? Shouldn't we open a ticket to MkvToolnix's bug tracker?

Anyways, I will check that option too, maybe I'll put a setting to select which road you want to take. Thanks [ReX]!

[rsotome]

Hmmm, so far, so good, really nice extraction program.

A batch option would be very useful, but I understand you'll need time to implement something like that.

Something that would really be very useful would be the ability to extract the video track straight into an mkv container, instead of the raw video, is that possible?
