Audio out of sync on Chrome, Edge and Firefox on Windows 11

The problem is two fold, they are in TS containers and they are transcoding when played back. TS containers are really not meant for playback. They can work fine some of the time, especially if they are direct played. This is the case for my recordings. But, often, when transcoding or remuxing TS recordings you can get these kinds of de-sync issues.

What you can try to do is manually remux your videos into MP4. Do not overwrite the originals. We are just testing if this works.

Code:

/usr/lib/jellyfin-ffmpeg/ffmpeg -fflags +genpts+igndts -i "/path/to/video/ts" -map 0 -codec copy -max_muxing_queue_size 2048 -max_interleave_delta 0 -avoid_negative_ts disabled newFile.mp4

Then add that new file to a test library and see if it plays ok.
