Which build did you download? We don't provide official LE10 builds for RPi0-3, only RPi4.

so long,

Hias

FYI: the latest development version of the deinterlace patches are now in LE master, today's RPi4 testbuild (http://test.libreelec.tv/LibreELEC-RPi4…126-8797e08.tar) already includes them. RPi2 testbuild with these patches will follow tomorrow.

It sounds like you are searching for PINN or NOOBS https://github.com/procount/pinn

You'll find more info about these on the RPi forums https://forums.raspberrypi.com/

run rpi-eeprom-config -e and set these options

WAKE_ON_GPIO=0
POWER_OFF_ON_HALT=1

I just noticed 2 more things in the log:

The file is a 50fps video, you may need force_turbo=1 in config.txt for smooth playback.

And you don't seem to have 1920x1080 / 50 Hz in your whitelist so 3840x2160 / 30Hz is chosen - which usually doesn't work well with 50fps files. Add that mode to the whitelist - and better also set kodi gui to 1920x1080/60Hz

The logs show you were playing from NFS. Can you test if you have the same issue when playing from a local USB drive?

If yes then a short sample file (1 minute or so) that has the issue would be nice.

20211120-62b201b also includes ffmpeg changes https://github.com/LibreELEC/LibreELEC.tv/pull/5889 and I'm suspecting they could be causing the issue. If that's the case our ffmpeg guru will need a sample to reproduce and analyze the issue.

Quote from rschupp

I see similar behaviour (LibreELEC-RPi4.arm-11.0-nightly-20211117-df8716a.tar):

video freezes for a few seconds while audio continues, then suddenly video catches up. When the video has finished playing the last frame is still displayed until I explicitly stop it.

Thanks for the log, I could reproduce the VIDIOC_DQEVENT errors and PR'ed a fix for it https://github.com/LibreELEC/LibreELEC.tv/pull/5888

The fix for the kms driver is still missing, so this is expected.

Thanks a lot for testing, it's great this is working now - this was a tough puzzle to solve

We'll include the necessary config changes in LE so future LE versions will support the official 7inch display.

Hias

BTW: also make sure you are using HDMI0 (the one next to the power connector on RPi4) - HDMI1 only supports up to 4kp30.

Please post the outputs of "modetest | pastebinit" and "pastekodi"- this will show what modes are available (and a copy of the edid).

Most sinks won't list 4kp50/60 modes at 4:4:4 in the EDID unless you enable "HDMI Deep Color" at the sink - then 4k 4:4:4 is limited to 30fps and only 4:2:0 (which the RPi doesn't support) 50/60fps are listed.

YCbCr 4:4:4 isn't supported in the driver either, the proposed kernel patch would add that along 4:2:2 as well.

IIRC all matrices and BT709/2020 colorspace signalling should be fine now.

Hias

New day, new try - I noticed I missed one option: https://www.horus.com/~hias/tmp/libr…442-9bbb99c.tar

Please report back if it works. If it doesn't please post your config.txt (Note that IIRC you need to have ignore_lcd=1 in it, and the 7inch dtoverlay after the "include distroconfig.txt").

Hias

Thanks for testing!

The main problem with the DSI drivers is that the kernel ends up in an endless probe loop if something is wrong (eg a driver missing or not initializing) without telling you what failed - several drivers just silently pass on errors without logging anything so there's no chance of finding out which of the sub-sub-sub components are missing or failing to initialize.

I get the same lockup (endless probe/bind loop) here with the 7inch dtoverlay loaded. I don't have the display, so I'd expect things to fail, but not as badly as they do (unable to complete kernel boot) and tons of meaningless errors on the serial console.

At the moment I'm at a complete loss, I think I have all the required dependencies enabled and no idea what else might be missing.

so long,

Hias

Not easily, you'd need to build kernel and kodi with the current WIP patches (same for LE).

config.txt is in /flash/ - see our Wiki https://wiki.libreelec.tv/configuration/config_txt

so long,

Hias

YCbCr 4:2:2 is supported by the hardware but not implemented in the driver and/or kodi yet (a complicated story...). Eventually support should be added though.

To get 4kp50/60 output (at RGB 4:4:4) you need to add hdmi_enable_4kp60=1 to config.txt - the HDMI sink also needs to support that and signal it via EDID.

so long,

Hias

Next try, could you please test with this build: https://www.horus.com/~hias/tmp/libr…536-90f3d53.tar

I found a couple more modules need to be built into the kernel.

Hias

Please provide a short sample file (1 minute or so) that has this issue. Also please test that if the issue occurs too when playing from a local USB drive to rule out network/nfs issues.

so long,

Hias

Please give this build a try: https://www.horus.com/~hias/tmp/libr…232-e829476.tar (just copy it to the update share and reboot)

I noticed we were missing some kernel config options, they are included in this build.

so long,
