14 DAY TRIAL // MKVToolNix is a complete set of tools to create, alter, and inspect Matroska files under Linux and other platforms. This application has been updated and the developers have made a number of important changes and improvements.
There aren't too many tools on the Linux platform that can perform this specific task, but the same is not true for Windows. This is one of the reasons MKVToolNix is such a famous application. The fact that it's among the best apps of its kind on Windows also shows just how good the app is.
It's difficult to draw comparisons with other similar applications when there are none available, but some of the media players on Linux have various plug-ins that can perform this kind of operations, although on a simple scale.
What the devs are saying about the MKVToolNix
"With these tools one can get information about (mkvinfo) Matroska files, extract tracks/data from (mkvextract) Matroska files and create (mkvmerge) Matroska files from other media files. Matroska is a new multimedia file format aiming to become THE new container format for the future," say the devs on the official website.
The release notes cover all the supported platforms, so don't be frightened if you find something for Windows only. If it's not specified, then it probably applies to all the operating systems.
According to the changelog, a first preview version in the Windows installer and portable releases has been added, calculating the AC3 delay from garbage data is now working properly when reading AC3 from AVIs, SSA/ASS files with sections after "[Events]" in their "CodecPrivate" are now handled correctly, the handling of certain edit list types in MP4 files that are used for positive track delays has been improved, and the compilation with Boost 1.56.0 which changed the indexed range adaptor in an incompatible way has been fixed.
Also, when editing files with missing track UID elements, such an element will be generated automatically, reading Matroska files with missing track UID elements will no longer cause mkvmerge to abort with an error, and a few other changes and fixes have been implemented.
Where to get it
With MKVToolNix, users can get information about (mkvinfo) Matroska files, extract tracks/data from (mkvextract) Matroska files, and create (mkvmerge) Matroska files from other media files.
