Rpi 4, green artifacts with 10.0.2 - 10.0.4 version on ff-h264_v4l2m2m-drm_prime streams

Quote from kimosak

Hello,

I am facing issue with LibreELEC 10.0.4, 10.0.3 and 10.0.2. There are green artifacts over whole screen each 15-30 minutes. This appear everywhere, I mean in live PVR, IPTV, or streamed movies with codec ff-h264_v4l2m2m-drm_prime streams. No issue with 10.0.1 and older. I've tried to search difference between 10.0.1 and 10.0.2 in change log but no luck there.

Running on Rpi4 4GB + Pi TV HAT, max temperature 57°

Any idea what it causing or how it solve? (Instead of downgrade, which helps)

Now I am running on 10.0.1 which has no issues.

Any reply much appreciated

Thank you

Hi,

If the that "greeen artifacts" appears mostly with Live TV, with drm-prime codec and deinterlacing, you should try the latest LE11 beta (10.95.1). If you have a spare SD-card, or make a backup and upgrade... Few weeks ago was added some kind of patch to ffmpeg to improve the deinterlacing (mostly for PVR). I have RPi3B, TVheadend, that "greeen artifacts" what I seen before too, I think now gone (true, I don't spent too much time watching the TV).

Could be this issue which is fixed on Nexus builds.

Is this fix in le 11 nightly? I can provide sample mkv .with green artifacts

Yes, nightly build is Nexus and contains the fix.

ok, just tested my file and it had issues on vlc on windows too, I guess it was the file then. carry on!
