[Matroska-devel] Tagging MKV files

Hey,

You've obviously done something wrong ;) Three things:

1. Look at your file with mkvinfo -v -v and look for "suspicious"
things. I cannot really be more precise; things like "unknown
elements" or "dummy element" would definitely be suspicious.

2. You can also use "mkvmerge --identify-verbose yourfile.mkv" before
and after your modification. It should show identical output safe for
the tags. However, this is a pretty superficial test, so you cannot
derive validity from a successful comparison.

3. The seek head positions they point to are relative to the segment
position! Check that with mkvinfo -v -v and compare it with known-good
files.

Kind regards,
mosu
