[RPi4] Video Cuts Out Randomly

  • Hi All,

    I have been having this issue with the Raspberry Pi 4 and Libreelec 12.01. When I play x265 10-bit videos in the initial 10 minutes I get random video/audio drops to a blank screen for several seconds. If I go back and replay where it cuts off it will do it again but in different time of the video. After it gets going it stops but it could come back randomly as well. I am not sure what is causing this. If I take the HDD over to my computer it plays fine. Has anyone seen this issue before?

    Thanks

  • Are you using 4K "certified" cables? .. 4K 10-bit media (and often HD audio) combined will be pushing higher data rates on the HDMI cable and dropouts are a textbook symptom of a cable that can't sustain the required data rate.

    Thanks for the reply. I am not sure but only using 1080p for this. I'll try another cable. Thanks!

  • Please provide a full debug log.

    How to post a log (wiki)

    1. Enable debugging in Settings>System Settings>Logging
    2. Restart Kodi
    3. Replicate the problem
    4. Generate a log URL (do not post/upload logs to the forum)

    use "Settings > LibreELEC > System > Paste system logs" or run "pastekodi" over SSH, then post the URL link
  • If the media is 1080p it's unlikely to be an HDMI bandwidth issue unless you're using a particularly rubbish cable. However, 1080p content is normally 8-bit not 10-bit which suggests media has been intentionally encoded that way, which opens the door to people using exotic encoding configs, e.g. in the past the Animé scene used 10-bit H264 which often caused issues. So plan B might be to rerip the media using Handbrake default HEVC settings.

    You may still be correct about the cable being the issue. I have not seen this issue when the bitrate is around 1500, but anything in the 3000 for 265 10-bit seems to have the issue. I may get a mini-HDMI cable to HDMI and see if that works better.
