Before reporting a bug

Please make sure that you've read the documentation before submitting a bug report. If you're sure you've found a bug - e.g. if one of my programs crashes with an obscur error message, or if the resulting file is missing part of the original data, then by all means submit a bug report.

Reporting bugs via GitLab issues

I use GitLab's issues system as my bug database. You can submit your bug reports there. Please try to be as verbose as possible and answer at least the following questions:

1. Which MKVToolNix version are you using? Have you also tried the latest release?
2. Which operating system and architecture (32bit vs 64bit) are you using?
3. What did you try to do? If possible include the command line if the problem is not strictly limited to the GUI part of one of the programs.
4. What was the expected result?
5. What happened instead?

If at all possible please provide sample files as well so that I can reproduce the issue. If you don't have a place to upload them to, you can upload them to my SFTP server.
