AndreStarTrek these are all known issue, scroll back through the thread. Several bits and pieces are still missing in kodi and video driver ATM.

The easiest way is to disable the IR receiver kernel module. Check the output of "lsmod", on a NUC you should either see ite_cir or nuvoton_cir.

Then create a modprobe conf file to blacklist the module. eg

/storage/.config/modprobe.d/noir.conf

blacklist ite_cir

Please stop messing around with config.txt and do the very simple thing I told you: start from scratch with a fresh installation and only add the video parameter to cmdline.txt.

I'm very confident that adding that single option to cmdline.txt will solve your video problems and that the other issues you are seeing are caused by your messing around with config.txt / gpu mem / video driver etc settings.

You can save yourself and me a lot of time by following the advice I gave you.

Sigh. If you disable distroconfig.txt and manually enable fkms the hdmi options will of course have an effect - but you should not do this.

The thing I asked for is very simple: does the video option added to cmdline.txt on a clean LE10 installation, with unmodified http://config.txt/distroconfig.txt give you a working screen or not?

If it works, please post a pastekodi log and your edid.

OK, your TV seems to be a "HD Ready" one with a 1366x768 panel inside. RPi4 doesn't support this mode, the kernel driver filters that out, but your edid seems to contain a detailed node entry which shows up as 58Hz in kodi log and isn't filtered out.

Does it work if you append video=HDMI-A-1:1920x1080M@60 to cmdline.txt?

PS: please use the "pastekodi" script to generate logs.

Please start with a clean installation of LE10 and just add video=HDMI-A-1:1920x1080M@60D to the end of cmdline.txt (in the same line, separated by a blank from "quiet".

This should get LE into a state where you have screen output and can grab logs and your edid.

Note: if you had to add hdmi_force_hotplug=1 and manually configure hdmi modes it could also be that you have a defective cable - this isn't too uncommon and can lead to hotplug detection and/or edid reading not working.

Don't add hdmi_enable_4kp60=1 to config.txt yet - 4kp60 isn't implemented in the video driver yet and if you add that to config.txt you get the issues you described.

linuxuser sorry, my crystal ball is currently on repair. Not much we can do without a debug log or a sample to reproduce.

Maschingun thanks a lot for your edid!

It looks like the TV successfully added speaker allocation map and audio formats from your soundbar. On my LG C8 I only get 2-channel PCM and no speaker allocation block - and I assume that without the soundbar your TV would provide (almost) identical information.

linuxuser could you please test this build: LibreELEC-RPi4.arm-10.0-devel-20210319162105-f44683e.tar - that should make TrueHD/Atmos available on your TV.

Thanks a lot for reporting back, and I'm glad it's working fine!

Don't get too excited, v4l2 is for grabbing from USB/PCI capture devices - for GBM hyperion will probably need to use a completely different approach (eg kodi addon that gets access to the decoded video data).

Hias

No, there's nothing you (or anyone else) can do ATM - stick to 4kp24/30 files for now.

so long,

Hias

If you tested with 4kp60 files then this is expected - the performance of the HEVC is not what it should be, the RPi video codec guru is currently working on improving that.

Playback over network can also be problematic with high-bitrate files, especially if you are using Kodi's built-in smb client and ts files. Enabling buffermode 1 in advancedsetttings, using an OS-level smb/cifs or NFS mount might help in that case.

Hias

Not sure what you mean with "will have any buffers".

As posted in the HDR thread RPi4 testbuild with HDR support BT2020 and 10/12-bit output handling are currently missing in the video driver and kodi. The RPi4 will decode 10bit 4k HDR videos up to 30fps fine, but output is not fully "proper" yet.

so long,

Hias

We don't have a release date for stable LE10 - it'll be released when it's ready. RPi4 isn't fully feature complete yet (eg no 4kp60 or deinterlacing) and the missing bits will be added over time - so we'll probably call it "beta" for a while.

so long,
