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 Trac
I use Trac as my bug database. You can submit your bug reports there. Please be as verbose as possible - e.g. include the command line, if you use Windows or Linux etc.pp. If at all possible please include sample files as well so that I can reproduce the issue. If they are larger than 1M then please upload them to my FTP server (the address is "ftp.bunkus.org", user name "upload", password "only" -- each without the quotes) and put the file name into the bug report.
Reporting bugs via email
If, for some reason, you really don't want to or cannot use Bugzilla then you can also email me with a bug report. Please try to be as verbose as possible and answer at least the following questions:
- Which MKVToolNix version are you using? Have you also tried the latest release?
- Which operating system and architecture (32bit vs 64bit) are you using?
- 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.
- What was the expected result?
- What happened instead?
Please note that I cannot help you properly if you don't give as much information as possible. I will probably refer you back to these questions. This is not because I'm rude but because I'm actually trying to help you, but it isn't always possible to do that without knowing the whole picture.
