Certain content on mobile giving playback error - Axtasium - 2025-02-23

I am trying to play certain video on my phone and it will not work. It works on pc fine, and if I set the player on mobile to use vlc externally, it also works just fine, just not using the web or integrated player on the app. Is it because MKV files are unsupported on the mobile app or am I missing something maybe?

Can you share your jellyfin logs via privatebin.net? And if there are related ffmpeg logs, share those too.

Also, what are the specs of the server? Both OS and hardware? And what kind of phone?

Its running on my Ugreen nasync dxp6800 pro (It uses a custom Linux Distro, I can look up specifics if you prefer that, or you can just google it), and the phone is a Samsung S23 Plus. As far as the logs, would that be on the system jellyfin is running on or my phone? if its supposed to be on the system, I have zero logs.

Go to the Jellyfin dashboard in a browser. In the left side scroll to the bottom of that list of Dashboard menus and open the logs Dashboard.

Before sharing the latest log, log_20250225.log, replicate the problem first then share that log via privatebin.net. Just click on the log, it will open the log in your browser, select all, copy, paste into privatebin.net, save, share the link.

It looks like it is trying to transcode but failing. Can you also share a ffmpeg log? And share how the container is configured? Did you pass the GPU into the container?

Heres the FFmpeg log

On the note of how its configured, I know like basically no Linux at all and just followed a guide so I have zero idea to be honest. All I know is that its only an issue on mobile, on my desktop it plays just fine, so I'm not sure if its something with the mobile app or if I goobered something not knowing what i was doing.

I can give you a link to the guide I used if youd like it, but I used Docker on the NAS and manually SSH'd into it and installed portainer and Jellyfin. I have hardware acceleration enabled in Jellyfin using Intel QuickSync as its an intel cpu with integrated graphics. Beyond that I really dont have too much of an idea as Linux is a bit over my head at the moment.

If the desktop is direct playing, the GPU does not come into play. If the phone needs video transcoding, but you didn't setup the container correctly, that would explain why it fails.

You'd need to provide either a YML file for the docker container or screenshots of portainer. It looks like the GPU is not accessible to the container based on the ffmpeg log you provided.

Alright, sorry for the inexperience on my part. I'm not sure where to get a YML file, but ill look and see if I can get it and send what ive got for now. I'm not sure what you need from portainer either so Ill add some images. All I DO know is that its off. The guide says it included enabling it, auto updates, and auto restarts, but docker lists it all as disabled. I guess I configured it wrong in that case but not sure how to fix it. Sorry for all the images, but I'm gonna dump the stuff I can see from portainer and docker. lmk If there's more you need or what I should/need to do.

Heres what I was given to use to create the Jellyfin stack as well.
