Screensaver during playback every 20 minutes

[bits0rcerer]

On my LG OLED48C17LB running webOS 6 and the LG store version of jellyfin, I get the screensaver around every 20 minutes during playback. The playback goes on but i see the fireworks and i have to press a button on the remote.

I am also having this issue. Did you ever find a resolution?

I am also having this issue on LG C1 on the latest firmware. The fireworks screen saver comes on every 20 min when using the jellyfin app from the webos store. If I access jellyfin in the TV web browser, I don't have any issue with the fireworks screen saver showing while playing a video.

Screen Saver always works except while playing a video in the full screen mode, and you cannot disable it without the option.

The app doesn't switch to fullscreen - it is maximized. In the browser, it does this to hide the browser UI.

I'm not sure if it is possible to switch to fullscreen from the frame that is used to display the hosted webui. Also, the same problem exists with the photo library, where there is no video to switch to fullscreen.

We probably must specify screenSaverProperties in the appinfo.json.
