I installed the new OSMC on a Raspberry Pi 4 and here are the problems I encountered.
At the first boot, the screen remained black. I had connected the HDMI-0 (next to the power supply). I plugged it into the HDMI-1 and it worked.
CEC was not working with my Samsung TV. The solution of turning off the RPI and the TV for 60 seconds didn’t work. I switched back to HDMI-0: the picture and CEC works.
When I launched a video, the image was not displayed, but I had the sound. The following error was in the logs:
ERROR <general>:
Object: plane ID: 68
Property: FB_ID ID: 17 Value: 227
Property: CRTC_ID ID: 20 Value: 74
ERROR <general>: CDRMAtomic::DrmAtomicCommit - atomic commit failed: Invalid argument
ERROR <general>: CDRMAtomic::DrmAtomicCommit - test commit failed: (No space left on device) - falling back to last successful atomic request
I decreased the size of the display (Settings / System / Display / Video calibration…) and the image is displayed. Maybe the problem comes when OSMC tries to display a pixel outside the screen. (v19 - RPi4B cannot play some video: CDRMAtomic::DrmAtomicCommit - test commit failed / vc4_place: Don’t reject fractional source coords)
So far, I haven’t had any other problems. Thank you very much for your work.
