DLNA Panasonic Internal Server Error 500

[gnmbj0ß94678]

Hey guys,

I'm running into Internal Server Errors 500 when trying to cast to a Panasonic TX-58GX800W using DLNA.
Why cast to? The OS is My Home Screen 4.0 and it has no Jellyfin app, and the TV itself does not show/discover Jellyfin as DLNA device.
Therefore I can only cast to the TV, but this generally works with other apps.

Jellyfin is 10.8.13 and was installed using Windows installer.
Here are logs using DLNA debug logging:

Code:

...

Do you have transcoding setup?

[gnmbj0ß94678]

Yes, but it should not trigger on 1080p h264 anyways for this TV.

Try creating a DLNA profile of your device since it doesn't have one. It is using the default profile.

[gnmbj0ß94678]

Ah, I did not notice that it couldn't match a profile, despite calling it correctly Viera.

Well, I copied over the system profile for Panasonic Viera, with slight adjustments, e.g. VIErA instead of Viera.

Now it matches the profile, but I still get 500s:

Playback for a h264.mp4 did work, but only if nothing is currently playing - if something is playing -> 500. That's unexpected behaviour?

Unfortunately, I don't know much about DLNA and how Jellyfin behaves when using it (I don't have any DLNA devices).
