That seems like a buggy firmware of your TV. Probably incorrectly detects RGB Full/Limited. Look if there is a setting that controls HDMI black level.
-
Go to "Passthrough output device" setting and switch to the correct port.

9.2.8 use mmal. 10 use drmprime. I suppose drmprime implementation on RPi is somehow more taxing than mmal.

The sample file is corrupt
The issue is that the stream gets corrupt when using a tv server and client on the same Pi + deinterlacing. This is totally RPi-specific.

The last time I tried tvheadend with my TBS 5520SE I had exactly the same issue.
Try VDR/VNSI instead of tvheadend. That's what I use with no such issues.

Are you interested in more detailed bug reports?
My builds are just a preview of lrusak's work-in-progress (the HDR part). No need for detailed bug reports at this point.

No X11 = no xrandr.
You can use proptest to switch to RGB full.

I had the same issue on a pi3. The issue was that when running both tvh client and server on the same pi AND using advanced deinterlacing method - green artefacts would appear from time to time, also continuity counter errors in tvh log.
The solution was to use BOB deinterlacing instead of "advanced". However, BOB looks much worse than advanced.
Another solution was to increase the arm_uc value, e.g.:
I don't have pi4 so no idea if this would work.

I still think it is a codec issue in the nightly build.
It's an issue with Intel media-driver. The fix is already in the media-driver master branch. I compiled and tested a build with an updated media-driver and HW acceleration works fine on my i5 12400 box.

I assume you are using rpi kernel 5.15.18.
Looking at the git commit history it looks like this commit was merged to kernel 5.15.17, so you may want to revert it for testing.

Your CPU is too weak to decode 4K video in software.
I believe that current LE master does support nvidia after this PR. The image has to be built with Wayland (PROJECT=Generic ARCH=x86_64 DEVICE=wayland).

Just copy the image to storage/.update and reboot

I posted a newer build here. No idea if anything changed for AMD.
