Title: Second audio track and subtitles missing [Solved]
Post by: lello on March 19, 2022, 01:57:08 am

Strangely I can't see the full subtitles and second English track of some files. Thinking it was a problem of MC29, I tried to open them with MC28 but the problem remained.

I then downloaded VLC, and here everything works correctly: what can this depend on? This is the first time this has happened to me.

If it helps, I am attaching the Mediainfo file obtained with SoT.

Thank you

The only reason tracks wouldnt be shown on some MKV files in particular is when those tracks are set to disabled in the file - in which case not showing them is what the MKV spec indicates, unfortunately other players just ignore that and show them anyway.

Unfortunately MediaInfo does not show this information in its output to clearly give this indication.

If you have created these files yourself with eg. mkvmerge, you should be aware that when you re-mux from eg. MP4, it can copy these flags from the input, and you should make sure all tracks are actually set to enabled.

You're right. Thanks to mkvtoolnix, I found that those tracks weren't enabled.
I made the necessary corrections, and now everything works. :)

Thanks Hendrik
