Was running Ubuntu Noble and mpv-0.37 is from Noble-repo. On Trixie the mpv is version 0.40 (Debian Trixie repo) which somehow does not seem work with the ffmpeg-v4l2request. Are you running Trixie or Bookworn? Is your device Opi5-Plus or RK3588? So far on my Opi5-Plus no luck with 10Bit Hevc or any 10Bit video on mpv with mainline kernel.

I confirm that when building an image with the Edge 6.18 kernel, WiFi does not work. Also, when building an image with the Xfce desktop, the image is approximately 3 GB (it should be more than 4 GB), but it is not there, only the command line works.

Hi everyone, I have rock 5c with PWM fan. I want to control the fan speed manually. Running on Armbian 25.11.1 Noble. Sorry if its obvious I am newbie to this

I was surprised when mine played H265 10 bit. I thought I'd read somewhere v4l2 was limited to 8 bit. Obviously that was incorrect.

I'm very new to Armbian so I could be off track here but I noticed your running MPV version 37. When I ran the instructions for the first time I already had mpv installed (version 40 or something) so it didn't get updated. I ended up uninstalling MPV and running the instructions again. Now I have version 35.1 which fixed the drm_prime errors for me. The version difference could be because you are on 26.2 of Armbian and I'm on 25.05, I haven't got my head around all the different versions of things yet. Maybe try uninstalling MPV and trying the commands again and see what version it gives you.
