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

  • 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).
