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).

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

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.

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.

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.

Which LibreELEC version did you use? If it was 9.2.6 then please give LE10 beta1 a try.

Note that the old hdmi_xxx settings in config.txt won't have any effect in LE10 - you can use eg "video=1280x720M@60" added to the end of cmdline.txt to select a different default mode though.

Switching back to fkms will bring back screen tearing, you loose HBR audio passthrough and HDR and you won't get any support from us. Other than that you are of course free to do that - just don't complain if things don't work

no. hyperion(ng) doesn't have a grabber supporting GBM - see also here Raspberry Pi 4 with Libreelec v19 / Kodi Matrix, no grabber is working · Issue #983 · hyperion-project/hyperion.ng · GitHub

Thanks for reporting, the issue affects all service addons. A fix will be in the next LE release Revert "kodi: service addon wrapper call fix" by HiassofT · Pull Request #5251 · LibreELEC/LibreELEC.tv · GitHub

As a workaround disable and then enable the addon again, then it'll work as expected, too.

Start with 2, and also send the email to Sean Young (he's the IR remote maintainer). When he acceptet your patch create a PR for LibreELEC, ideally with a link to the linux media patchwork URL.

Maschingun thanks for the info! I'd still be interested in seeing your edid, if you have time please run the command I mentioned in post 155 RE: RPi4 testbuild with HDR support

With pastekodi -c > mylog.txt you can save the log into a file - then copy it via scp/sftp to your PC and attach it here. You can also grab a ZIP with logs from the "Logfiles" smb share - and again attach it here.

smp you are forgetting that kodi/ffmpeg aren't able to decode the object-based Dolby Atmos or DTS:X (sub-)streams - AFAIK there are no open source decoders available for that.

Without passthrough you only get the core TrueHD or DTS streams that ffmpeg can decode - only AVRs and TVs can support all features of these sound formats, so HBR audio passthrough isn't just a niche feature.

Hias

Maschingun thanks for the logs!

Can you please run the following command via ssh/putty and post the output URL?

od -t x1 /sys/class/drm/card0-HDMI-A-1/edid | pastebinit

Also: did you connect the RPi directly to the TV or via the soundbar? Which soundbar are you using?

so long,

Hias

This error usually means your putty is too old.

You can also use the logfile upload function in LibreELEC settings and then post the URL you got on your TV - see also Log Files - LibreELEC.wiki

No one has a Solution to my Problem?

Most likely you are running into the same problem as linuxuser but we don't know for sure as you didn't post a pastekodi log.

any news on fixing hbr audio problem that doesnt appear to all tvs?

Not yet. It's a bit tricky and we have to be careful not to break other configurations.
