MKVToolNix does not show subtitles for some Media
Hello,
MKVToolNix does not show subtitles for some Media files. (They're usually MP4)
Screenshots: You can see the subtitles are available when playing with VLC or any other player. https://i.imgur.com/ldqsSh9.png
But.. as you can see from this screenshot MKVToolNix doesn't detect the subtitle. https://i.imgur.com/4XdnVPW.png
So can you fix this issue please? Thank you.
