; is a tool for repairing Matroska video ( .mkv
) files that get stuck during playback.
If you have a .mkv
file that hangs during playback, it is likely that there are discontinuities in its timestamps. Open it in FixMKVGaps
and it will immediately analyze it.
After a few minutes, it will give you the result of the analysis: it will tell you if the file is correct (but only from the point of view of time codes) or if there are gaps. He will also tell you where they are.
If the mkvmerge
tool is installed on your system, FixMKVGaps
will use it to remux your .mkv
file by removing all the “gaps”.
It will leave the original file unchanged and create a _fixed.mkv
file that will be the repaired file. You can then delete the old one, if you want, and read without blocking the new one.
