Version history / Release notes / Changelog:
2015-01-04 Moritz Bunkus <moritz@bunkus.org>
* Released v7.5.0.
* mkvmerge: bug fix: If the target drive is full then a nicer error message is output instead of simply crashing due to an uncaught exception.
* mkvmerge: bug fix: Fixed reading MPEG transport streams in which all PATs and/or PMTs have CRC errors. Fixes #1100.

2015-01-03 Moritz Bunkus <moritz@bunkus.org>
* all: bug fix: Re-wrote the whole checksum calculation code. This lead to a fix for the Adler32 checksum algorithm that was triggered under certain circumstances. Adler32 is used in mkvinfo's output (e.g. in summary mode or if checksums are activated), in the h.265/HEVC bitstream and TrueAudio (TTA) file headers.

2015-01-01 Moritz Bunkus <moritz@bunkus.org>
* mkvmerge: bug fix: fixed handling of HE-AACv2 with object type »parametric stereo«.
* mkvmerge: new feature: implemented support for MP4 DASH files. Implements #1038.

2014-12-31 Moritz Bunkus <moritz@bunkus.org>
* mkvmerge: new feature: implemented reading MPEG-H p2/HEVC video tracks from MP4 files. Implements #996.

2014-12-30 Moritz Bunkus <moritz@bunkus.org>
* mkvinfo: bug fix: track statistics: the duration (and therefore the estimated bitrate) was wrong for files in which the frame with the maximum timecode wasn't the last frame in the file. Fixes #1092.
* mkvmerge: new feature: implemented support for AAC in LOAS/LATM multiplex if read from MPEG transport streams or raw LOAS/LATM AAC files. Implements #877 and fixes the underlying issue in #832.

2014-12-21 Moritz Bunkus <moritz@bunkus.org>
* build system: libEBML and libMatroska have been changed to provide pkg-config configuration files. Therefore MKVToolNix' build system has been switched to look for both libraries via pkg-config.

2014-12-20 Moritz Bunkus <moritz@bunkus.org>
* all: bug fix: several fixes have gone into libEBML and libMatroska that prevent illegal memory access (both reading from and writing to unallocated addresses). The bugs #1089 and #1096 have thus been fixed.

2014-12-19 Moritz Bunkus <moritz@bunkus.org>
* build system: libMatroska v1.4.2 is now required as part of a fix for #1096.

2014-12-18 Moritz Bunkus <moritz@bunkus.org>
* build system: libEBML v1.3.1 is now required as a part of a fix for #1089.
* mkvinfo: bug fix: mkvinfo will abort with a proper error message if the first element found is not an EBML head element. See #1089.
* all: enhancement: improved exception messages that can occur when reading damaged Matroska files to make it clearer for the user what's happening. See #1089.

2014-12-16 Moritz Bunkus <moritz@bunkus.org>
* mkvmerge: new feature: Added support for reading h.265/HEVC video tracks from MPEG transport streams. Implements #995.
* mkvinfo: bug fix: Timecodes output with ms resolution are now rounded to ms instead of simply cut off. Fixes #1093.

Great program Please don't post complaints or questions here. If you have problems and can't find an answer in the forums here then go to the 'Visit developer's site link" above.
will take you to this
15 Dec 2012: Closed the forum again and moved the "FAQ over to trac." (link)
Follow the link and search MKVToolNix bug tracker and FAQ.

The development team is very active and many bugs are fixed and versions are updated every 2 or months. (NOTE: I am just a user and not a member of the development team).

Header Stripping should be disabled by default in the next release. It would make it a lot easier for those having issues. The software works 100%. You just need to know what you are doing. Excellent work to the developers!

For those people who've left comments complaining about later versions of MKVMergeGUI creating MKVs which won't play on standalone devices, 99.99% of the time it's due to header removal compression. This feature is part of the MKV spec but it's not supported by many/most standalone devices. The solution is to go into MKVMergeGUI's options and to check "disable header removal compression for audio and video tracks by default". Once that's done MKVMergeGUI should once again create MKVs which will play on standalone devices.

Why header removal compression is enabled by default I don't know. It's probably the number one reason for "MKVs created by MKVMergeGUI won't play using my device" threads being started in forums. If not, it's maybe the only reason.

For those wishing to extract streams from MKV files, MKVCleaver is a nice companion tool to MKVMergeGUI.

This is now working on EVERY FILE I try it with. I need to remove DTS or HD audio from files and replace with AC3 for my Samsung HDTV.
This is so simple a kid could use it.
GREAT UTILITY!

None of the files output from version 4.0.0 onwards will play in any of my devices (Blu-ray player, multi-media TV, DVB box). I either get a file format not supported error or it will cause the device to freeze and then go in to standby. Newer versions (from around 5.0.0) also for some reason incorrectly save the files as using variable frame rate mode when they are in fact constant. Earlier versions do not do this. I don't know which changes made are to blame, but files from 4.0.0 up just aren't as compatible as from versions before this. My scores therefore are for version 3.4.0 and earlier.

Files muxed with v5.3.0 does not work in XBMC.
If I mux them in an earlier version, it works.

Anyone else experienced this?

Indeed, the problem is in your subs. I suggest Subtitle Edit. From the Tools tab you select Fix Common Errors. Check all the stuff you wish to fix. One option is to fix subs appearing on more than two lines.

If you are using Media Player Classic/ Home Cinema you can override the placement of subs
(Options->Subtitles->Default Style)

MKVtoolnix has got nothing to do with position of subtitles as far as I know.
If you have problems with subtitles, they are in the subtitles themselves.

Great tool one small annoying problem is that subtitles appear to be restricted to the middle third of the screen and break over 3 to 4 lines. Cannot see how you can change this.

Confirming the issue mkvextractgui fails with mkvtoolnix v5.2.1 but works splendid with 5.2.0.
Extracts different tracks than selected, or gives error and doesnt extract anything, or extracts but doesnt create any file.

Works great as usual.
MKVCleaver is a bit dated and is broken with this version, try MKVExtractGUI-2.

Version 5.2.0 breaks MKVcleaver (it's extracting wrong tracks). Went back to 5.1.0 and all's fine. Great tool though.

I used This version 3.3.0 because, I can play the movie in my DVD via USB. all version above this until you reach 4.8.0 does not work on my Philips DVD and My Philips can not read it. and easily, Just the DVD hangup when I put the USB in and try to play file. except for version 3.3.0, all files are playing very smoothly,

Making chapter inside Matrsoka files, really something great, But I wonder is there any way to import chapter into MKV from DVD.

About the tools itself, It is really great...

Thanks people

It did what I needed it to do, which was to make corrections to language from 'Undefined' to 'English', and also remove the "Created with AutoMKV 0.98.4 etc, etc...". Looks like it can add chapters too.

I had a difficult time figuring out why it would not play on my Sony BluRay player (BDP-BX37). Turns out I had to turn off header compression (fixed globally under "File>Options>Disable header removal compression for audio and video tracks by default".

I would like to see more through documentation.

Excellent tool for splitting/merging/redoing audio for MKV/H264/mp4 files...

Dunno why the latest version 4.9.1 wouldn't "append" files, all previous versions 4.80./4.9.0 have no problems appending files after splitting.

Version 4.9.1 fixes the freezing problem on opening files.
An essential tool for muxing mkv.

For those who have problems with their mkvs playing on commercial players, turn header compression off. Click on the audio / video stream, Then below click on the tab "Extra Options". On "Compression" select none.

Just like all ready mentioned in the comments,
The latest versions of MKVmerge give still problems for Playback on Multimedia systems
Sound OK, Video: --> Black screen.
The one I'm using is MMS P1080 from Traxdata.
What is the reason of this? Can't this be modified/resolved?

Great Program!!
I have never had any problems with it!!
As stated, i think mostin5000 needs to learn what a false positive is!!
Checking the latest version on Virus Total it comes up with 1 out of 42 by some no name unknown antivirus software, and also as stated, i don't think i would trust mcafee to screen my coffee, Zone Alarm, well...

It has not caused 1 single problem on my 2 systems and has been a great asset!!

mostin5000 doesn't know how to use antivirus or antimalware software. This software contains none. It is open source and Mosu is a frequent poster on doom9's forums, where he provides excellent support and assistance to users for free. "Shutdowner" is a generic label applied any software that has the ability to shut down Windows - mkvtoolnix bundles this options so users doing long muxing tasks can leave their PCs unattended and not waste power. McAfee and ZoneAlarm are bloated and poorly, ineffectual, written to a laughable extent - UNLIKE mkvtoolnix, which is an excellent utility and the application of choice for muxing Matroska files on any platform.
