I confirm I got my Orange Pi Zero 3 playing hardware decoded videos: * armbian official, built with the EDGE kernel 6.13.11, xfce environment * followed all the instructions in the first post of this thread * connected to a 1080p LCD monitor with HDMI * MPV plays a 1080p video with frame "tearing" with a window 800 pixels height. CPU usage 25% in all 4 cores * 720p video can be resized to almost full screen, but then it suffers tearing when resized larger. 10% to 15% CPU usage. * with all videos, when I try to play full screen, MPV plays the video every other frame, and shows a static frame (the frame that was showing when I double-clicked for full screen)

@Sirmalinton Are you sure this could be the reason? I have NVME's with btrfs running with following options in fstab defaults,noatime,nodiratime,compress=zstd,nodiscard,max_inline=0 And temperature is quite acceptable (see screenshot below). I had initially set up my NAS is the standard metallic case which was quite useless. So I got a 3d-printed one with a fan on the top to keep everything cool. See my post in another thread https://forum.armbian.com/topic/48705-cm3588-overlay-for-fan-speed-change/#findComment-214042. Now I don't have to worry about the temperatures at all. I must also mention that my NVME's have heatsink attached.

We provide mainline based kernels via repository. They are up2date with what exists, but support is not complete and also not tested on this particular hardware.

I did see that script. I disabled CGROUP_SCHED by commenting it out. I don't think that is the "right way", but it worked for now.

There is another feature of framework, "armbian-kernel", sections that applies on top of (basic) configs: https://github.com/armbian/build/blob/main/lib/functions/compilation/armbian-kernel.sh#L205-L336 (Docker as example)
