FireTV Stick Fails Playback when Transcoding Video if Subtitles are Enabled - boimouse - 2024-12-13
Hi There,
I am wondering if anything is in the works for this issue. If I am running the Jellyfin App on my FireTV Stick 4k Max, I find that getting a video to transocde works just fine (which is exactly what I want), the problem is when I enable subtitles. The video will fail to playback if subtitles are enabled. Additionally, if I watch a video with subtitles enabled without transcoding, then everything is fine. Then if I force the video to transcode, the subtitles are automatically disabled and the video is played fine until I try to reenable the subtitles (which then the playback fails again).
I checked if this was the case on my computer within Brave Browser and it was totally okay to play subtitles while transcoding a video (this leads me to believe it may have something to do with how the FireTV Jellyfin app handles subtitles.
P.S. The raw (embedded) subtitle files I have been testing with are simple mov_txt files which are basically subrip (.srt).
Android TV App Version: 0.18.2
Jellyfin Server Version: 10.10.3

Can you share your jellyfin and ffmpeg logs from the failed playback?

Thank you for the quick response.
Here is the log you requested. I know the video in the log here is an HDR10 video but I also tried it with non-HDR content and the same problem occurred.
In this example of the error I am experiencing, the process to recreate it was as follows: I began playing the video, then I enabled subtitles, then I forced the video to transcode (sometimes the subtitles get automatically disabled so I would re-enable them during the transcoded video playback which would recreate this issue as well), then it seemed to attempt to transcode and then it failed to playback the video and crashed the player.
P.S. I noticed in the log that it seems to be using the "VAAPI" preset for hwaccel but in the transcoding dashboard, it is selected as Intel QuickSync (QSV). I'm not sure if that has anything to do with it but I have an Intel GPU installed which I have been using.

Can you switch your container to host networking? It looks like the server is dying due to the websocket dying unexpectedly.

Here is the log after changing the container it to "Host Network."
I used the same steps to recreate the issue on the FireTV.

Are you connecting this FireTV client to Jellyfin through a VPN? Tailscale?

Yes I am using Tailscale from a TrueNAS Scale machine.

Is it possible to try without the VPN? To eliminate that as a factor.

I can but I would have to wait until I’m home to test that.

Here is the attempt without the VPN (all through local network "192.168...." and the container is set to broadcast on the host network).
I also attempted this through another android device (phone) and it transcoded with subtitles without crashing (they were out of sync but it didn’t fail to play back the video).
