RPi4 4k very slow

  • Hi,

    I have a RPi4 with 4GB and LibreElec version 10.0. If I play a 4k video via wifi like a 50GB mkv file the player is too slow.

    I have the default settings. Its my first time with 4k videos because the RPi4 and the 4K TV is new.

    Which settings are the best for 4k?

    Regards

  • Here are the information about the video file:

    Code
    VIDEO.CODEC............: HEVC [Lvl 5.1][10 bits][HDR10][BT.2020] FRAMERATE..............: 23.976 fps BITRATE................: 49929 kbps RESOLUTION.............: 3840x2160 [AR 2.40:1] 
  • Keep Kodi at 1080p "Desktop" and enable the whitelist with 3840x2160 @ 23.976/24/29.97/30 and 1920x1080 @ 23.976/24/50/59.94/60 with "Adjust refresh" set to start/stop. Make sure the Pi is connected to an HDMI 2.0 port that supports HDR/Deep Colour. If you want to play large filesize media you should use Ethernet, or be perpetually frustrated with the issues that come with WiFi connections.
