No video playback on Intel N200 minipc (MSI Cubi N ADL)

I would like to run Libreelec on my newly aquired MSI Intel N200 based minipc. After installing a fresh copy of the latest LE-generic, and made some basic settings, i didnt expect to run into problems, having used very generic hardware.

But to my surprise, after starting a hevc encoded video file, there is no playback. An exact description would be: the tv switches to the appropriate resolution and framerate (24p in this case), the playback starts, but i only hear the soundtrack of the videofile and the tv shows the LE interface. Switching to full screen playback does show the player osd buttons, but no video.

My logs can be found here:

Am i doing something wrong?

The device i'm trying to use is this one:

It is on its latest firmware, has al drives secure erased before installing LE (and all ssd's have their latest firmware), nothing out of the ordinary.

-edit: h.264 and vp9 playback seem to work fine. My issues are at least with hevc playback. Even av1 playback appears to work.

Don't enable DRM PRIME on Generic.

Thank you, that did the trick.

I didnt know what prime decoding was, i had to read up on that. I found this topic:

Thread

RPi5 "DRM Prime Decoding"

I'm sorry if this is a stupid question. I swear I tried searching first.

Can somebody explain what DRM Prime decoding is and the pros/cons of having it enabled? (RPi5)

where it was said that prime decoding is more efficient then non-prime decoding.

If i might ask, will prime decoding come to the generic build? Or is there something wrong with the generic build that prevents prime decoding from working?
