Solved Jellyfin Play Issues

[privsec]

Previously I have been able to watch media files on my Jellyfin instance that were in the mkv format.

I would use the iOS app to watch these files.

As of today, when I attempt to watch a show, I get this error

This occurs with every file on attempt to play the show.

Do you see anything in the app logs while trying to play such a file? Can you play it in the browser and if not also check the browser console logs. Presumably it has something to do with transcoding, given the format involved.

@nebulon
When I reviewed the logs, the only http status codes there was 200.

There are WRN logs but no error messages

Files do not play in browser either. I only have a phone near me for now, I’ll check the desktop browser shortly

Here are the logs from the app

@nebulon
It works without an issue in the browser on desktop

[nebulon]

This seems very much like a transcoding issue then. Unfortunately I am not able to reproduce this here to debug further. Can you also ensure that the app has a high enough memory limit to rule that out?

[privsec]

@nebulon
It is allotted 23 gbs of ram

How do I address transcoding issues, do you know?

[girish]

I have added VAAPI support in the latest package. https://docs.cloudron.io/apps/jellyfin/#hardware-transcoding has some information. Works on my server (tm).

@privsec Maybe it's the same issue: from time to time there is no way to see anything with the iOS yellyfin app. That's when I kill the iOS app and restart. Boom. It works again.
