SOLVED: Stream starts fast in browser, but slow on Android TV

[Curler1]

In the Jellyfin app on your TV, what is the audio output setting set to?  Direct or downmix?  And how about your refresh rate scaling?  Disabled, scale on device, or scale on TV?

Do you have trickplay support enabled on the CCwGTV?

I just checked. Audio autput is set to direct, refresh rate scaling is disabled and trickplay support in developer options is also disabled.

I just also tried to play around with all of these settings, but the loading times did not change noticeably. Any special combination of settings I could try?

I'll also try completely resetting the CC device again.

Resetting the device again did not change anything.

But I might have found the problem. I checked the main Jellyfin logs again and saw, if I interpret the logs correctly, that the subtitle extraction process takes more than a minute before playback starts:

Code:

[2025-02-17 10:55:09.858 +08:00] [INF] [26] MediaBrowser.MediaEncoding.Subtitles.SubtitleEncoder: "/usr/lib/jellyfin-ffmpeg/ffmpeg" "-i file:\"/data/media/movies/REDACTED.mkv\" -copyts -map 0:4 -an -vn -c:s copy \"/config/data/data/subtitles/0/09cd679b-efa3-7d84-3f7b-a8aada8540f9.srt\""
[2025-02-17 10:56:18.366 +08:00] [INF] [62] MediaBrowser.MediaEncoding.Subtitles.SubtitleEncoder: ffmpeg subtitle extraction completed for "file:\"/data/media/movies/REDACTED.mkv\"" to "/config/data/data/subtitles/0/09cd679b-efa3-7d84-3f7b-a8aada8540f9.srt"

Am I interpreting the logs correctly? Could this be the problem?

I already turned off "Allow subtitle extraction on the fly" and set "Disable different types of embedded subtitles" to "Allow None" for every library, but nothing changed.

Update: Ok I also had to rescan all libraries while replacing all metadata. Now all the embedded subtitles do not show up anymore and playback on Android TV starts quickly again. I'll mark this as solved. Thank you for your help @TheDreadPirate
