This page is meant to be a starting point for people looking to find information why the tools don't work as expected their or why their player doesn't play a file created by mkvmerge/MKVToolNix.

Information by version number

9.4.2, 9.5.0: stuck on muxing MPLS/Blu-rays

Muxing MPLS files from Blu-rays can cause mkvmerge to get stuck in an endless loop. The issue has already been fixed, and new pre-builds for Windows are available.

Current versions: Error message "JSON output could not be parsed"

It seems that certain anti virus tools prevent mkvmerge from getting executed properly. See this FAQ entry for more information.

General help

mkvmerge includes a lot of features that you can turn on and off in order to influence how the output file will be constructed. The page Improving playback compatibility with players lists them all including a description of typical symptoms.

Most articles in the playback FAQ category are also worth a look.
