Audio out of sync on Chrome, Edge and Firefox on Windows 11 - cfcman - 2024-11-15

From looking at Reddit it seems that this is not uncommon. Does anyone have a fix/workaround for the audio sync problem when viewing on a web browser on Windows 11? I've tried Chrome and Edge, and the audio is badly out of sync. I can't get playback to work at all on Firefox - just get a spinning wheel.

I'm using then latest version of Jellyfin (as at 15/11/24) on Ubuntu 20.04.

Can you share your jellyfin logs via pastebin? And the media info for your videos? Does this happen with every video or just some?

RE: Audio out of sync on Chrome, Edge and Firefox on Windows 11 - cfcman - 2024-11-15

This happens for all media - e.g. recorded TV, downloaded media as well as live TV
My logs are here:

I'm not sure how to get media info from jellyfin??

RE: Audio out of sync on Chrome, Edge and Firefox on Windows 11 - TheDreadPirate - 2024-11-15

Are these all live TV recordings in TS containers?

RE: Audio out of sync on Chrome, Edge and Firefox on Windows 11 - cfcman - 2024-11-15

Yes that's right - some recorded using Jellyfin DVR and some on a Humax PVR.

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.

RE: Audio out of sync on Chrome, Edge and Firefox on Windows 11 - cfcman - 2024-11-15

I don't have /usr/lib/jellyfin-ffmpeg/ffmpeg on my server - should that have been installed with Jellyfin?

EDIT: I guess maybe because I'm running Jellyfin in a Docker container. Is there any way that I can access ffmpeg from within the container to do this conversion??

RE: Audio out of sync on Chrome, Edge and Firefox on Windows 11 - cfcman - 2024-11-15

Ok in the end I installed ffmpeg separately, and ran it. This is the log that it produced:

ffmpeg -fflags +genpts+igndts -i "/media/barracuda4tb/Videos/TV/BBC London News; Weather/BBC London News; Weather 2024_11_15_13_35_00.ts" -map 0 -codec copy -max_muxing_queue_size 2048 -max_interleave_delta 0 -avoid_negative_ts disabled BBC_London_News_MP4.mp4

RE: Audio out of sync on Chrome, Edge and Firefox on Windows 11 - cfcman - 2024-11-15

Interestingly, Kodi is able to playback the same files without any issues, but I guess that's because the decoding is being done on the Kodi client?

RE: Audio out of sync on Chrome, Edge and Firefox on Windows 11 - gnattu - 2024-11-15

LiveTV recorded files will have audio desynced after remuxing. A workaround is to disable prefer fmp4 container but that also means you loss HEVC and AV1
