Artifacts (RPi4)

  • i may have a similar problem, fresh installation but i get purple/green artifacts while reproducing videos, tried both LE 10 and 11.
    RPi4 with (right now) LibreELEC-RPi4.arm-11.0-nightly-20230222-b7fce11.img.gz (sha256)

    ffmpeg[0x2a3c318]:   Stream #0:0: Video: h264 (High 10), yuv420p10le(tv, bt709, progressive), 1920x1080 [SAR 1:1 DAR 16:9], 23.98 fps, 23.98 tbr, 1k tbn, 47.95 tbc

    There is no broadcast standard for 10-bit H264 (yuv420p10le) media so almost nothing supports hardware decoding of that format, including RPi4. The file will be software decoded by ffmpeg and that might be a challenge. Traditionally Animé fans have used higher spec Intel kit for their collections; there is still zero hardware decode support on the GPU but the CPU has more grunt for the task. I'd suggest experimenting with transcoding 10-bit H264 files to HEVC. The transcode will be slow, but it's a one-time task and can be scripted easily.

    Seems like watching h265 10-bit will be a better idea then, thanks!

  • Hi, while I found the same issue as you, disabling DRM PRIME decoding works filn for hi10p files that I have, apart occasional frame drops, which is to be expected. And while there isn't too much moving subtitles and/or heavy KFX effects
