I have question about 4k30. I have mp4 files h264 and files not working. Only music/sound. Thumbnails are genereted but no video - black screen. What is wrong?? Rasbery Pi 4 4MB. Output resolution on HDMI is 1080p. Kodi should scale 4k to 1080p.
4K working if I disable DRM Prime Hardware Acceleration, but video is stuttering.
