Subtitle Extract plugin not working

[TheDreadPirate]

As with most things related to media servers, it depends on what the client is capable of. For the record, remuxing is simply changing the container before sending it to the client. No encoding. A potato can remux in real time.

Remuxing is sometimes necessary TO direct play the video/audio/subtitles. Some clients don't support playing audio and subtitle tracks that aren't the first one. Remuxing is necessary in those situations.

As for your database error. Do you have the Playback Reporting plugin installed? Disable it. I've reported this bug to the plugin git.

You can leave it disabled or delete the separate database the plugin creates and start over (I did the latter).
