Can start media but only get audio

[sethasaurus]

I believe this has only become a problem since a recent update.
I'm using Ubunutu. The server runs and I can access media and play it via a browser. jellyfinmediaplayer works as far as showing content, metadata, etc but will only play the audio from a movie, and no video output.

Errors I get when running jellyfinmediaplayer from the command line:
QSocketNotifier: Can only be used with threads started with QThread
libpng warning: iCCP: known incorrect sRGB profile

I get multiple errors in the jellyfin log, like this: (a couple every second, when attempting to play a movie file)
[2025-02-19 14:26:34.248 +00:00] [ERR] Error reporting playback progress

jellyfinmediaplayer.log shows:

Delete your JMP cache.

C:\Users\yourUser\appdata\local

Delete both "jellyfinmediaplayer" and "Jellyfin Media Player" folders.

[sethasaurus]

Thanks very much for the quick response! Just left the house but I'll try that when I get home. 👍🏻

C:\Users\yourUser\appdata\local

Delete both "jellyfinmediaplayer" and "Jellyfin Media Player" folders.

OK I deleted the cache and it's working. Thanks for the tip.

On Ubunutu, the location is :

~/.cache/Jellyfin Media Player
