Raspberry Pi 4 (LE 10) Video crashing on 4K content. drm:drm_atomic_helper_wait_for_flip_done] ERROR [CRTC:76:crtc-3] flip_done timed out

The device will start playing 4K Video for up to 10 seconds then video stops.

The display is blank.

The debug log has this line

Code

drm:drm_atomic_helper_wait_for_flip_done] *ERROR* [CRTC:76:crtc-3] flip_done timed out

I thought this might be heat, so I changed the case to one with a fan and heat sinks. This did not help.

I tried Xbian and OSMC. They did not crash, but they did not work correctly in other respects. So I don't think its hardware.

Any help gratefully received.

Thanks for the report! I haven't seen that issue myself yet and pinged the RPi devs.

Can you test if the video plays fine if you set the display resolution to 1920x1080? I suspect it could be related to the 2560x1440 resolution of your monitor.

so long,

Also please test with this build LibreELEC-RPi4.arm-10.0-devel-20210901104638-c91d4d4.tar (just copy it to the update share and reboot), it contains several HDMI and video decoder fixes that aren't in LE 10.0.0

so long,

Hi Hias,

Are these HDMI and decoder fixes in all the nightly builds from now on as well?

Thanks

**HiassofT** · September 30, 2021 at 12:02 PM

All HDMI and HW decoder fixes we have so far are in nightly builds.

Note though that the nightlies are based on LE 11 and Kodi 20 - better use the LE10 test build I linked above unless you are in a highly experimental mood and run them from a separate SD card (going back to LE10 most likely won't work without major trouble).

so long,

Hias

Hi Hias,

I'm working on a custom video player for the Raspberry Pi 4, and I'm running into this exact issue. Could you please give me some insight on how LibreELEC was able to work around it?

Thank you!

**HiassofT** · February 14, 2022 at 10:21 PM

We didn't work around it, latest RPi kernel/firmware and ffmpeg from jc's branch should be all you need.

I haven't seen the flip_done issue for quite a while now (both with 5.10 and 5.15 kernels).

so long,

Hias

I see, I'll give that a try. Thanks a lot!
