wyup refresh rate switching is essential if you want (micro-)stutter-free, smooth video playback. Cinema stuff/Blu-Rays are usually at 23.97/24 Hz, TV broadcasts at 50 or 59.94 Hz, PC videos often at 60Hz - if your video output mode doesn't match the video's framerate it'll look juddery.

Regarding DV: UHD Blu-Rays have a mandatory HDR10 base layer, so DV on these disc is an additional layer on top and RPi4/5 will output the HDR10 layer just fine - tested that here with 4k (DV) Blu-Ray rips I did on my own with makemkv.

Streaming services with "pure DV content" (without the HDR10 base layer) is another thing, and RPi4/5 certainly wouldn't have the grunt to process that - direct-to-plane rendering works fine for 4kp60 but GL/EGL rendering doesn't - it's too slow, even without shaders having to do tonemapping (RPi's graphics "chip" isn't anywhere near an Nvidia RTX).

Hard to say as you didn't post your addon/script but it could be that you may be experiencing this issue https://github.com/LibreELEC/LibreELEC.tv/issues/8447 (which isn't directly related to rpi-tools/gpiozero)

Please post detailled information, including your scripts, systemd units, debug logs etc.

Found time for a quick test, it also doesn't work in RPiOS so likely it's an issue in the RPi 6.6 kernel. I've opened an issue here: https://github.com/raspberrypi/linux/issues/5814

I found time for a quick test and could reproduce the issue here. It seems composite video out got broken when switching to kernel 6.6 - with kernel 6.1 it's fine.

I'll have a closer look after Christmas, for now best stick to builds from before 20231122.

The analog audio stuff in config.txt is fine - you need that to get analog audio regardless of using composite or HDMI video.

Not sure what the issue could be, please post a pastekodi log - run "pastekodi" via ssh and post the URL you got or use the "upload log files" function in LE settings and post the URL

This was a bug in the latest v4l-utils/ir-keytable version, I found and fixed it

v4l-utils: add patch to fix crash in ir-keytable by HiassofT · Pull Request #8438 · LibreELEC/LibreELEC.tv

Recent keytable changes missed to properly initialize a buffer pointer so it used random memory when reading keymaps in legacy format and crashed: LibreELEC:~…

github.com

The next LE12 nightly should work fine again with keymaps in the old (non-toml) format

RPi4 or RPi5 will work fine for this, I recommend getting a 4GB model (RPi4 2GB is also OK).

Dolby Vision isn't supported in LibreELEC but other than that the RPis will handle 4k HDR10 and HLG plus HD audio passthrough just fine.

Remove the "include distroconfig.txt" line from config.txt.

You can also remove sdtv_mode and overscan settings, they have no effect.

The pastesite ix.io went down before anyone could have a look.

Please update to the latest nightly build and post a new log (we've setup our own paste site which should be more reliable).

And that updated just fine.

So why no update on Pi 4?

Likely because there are no known issues or new features on RPi4.

Thanks for the report, I could reproduce this here on RPi3B+ if Adjust refresh rate is "off" in player settings.

A temporary fix/workaround should be in the next nightlies (when the PR got merged and images built)

Quote from MatteN

Still no new eeprom-update for Pi 4.

This is because there haven't been any new releases in the last couple of months

Make sure both PYTHONPATH and LD_LIBRARY_PATH are setup correctly to include the rpi-tools addon lib dir. The latter is automatically set up if you ssh in, but not in systemd services or autostart.sh

Yes, the update was merged yesterday and LE11 nightly builds are already scheduled - they should be available tomorrow or so.

so long,

Hias

The easiest way is to ssh in and run "rpi-eeprom-update -a" - this will update the EEPROM to the version included in LE (the next nightly builds will include the 2023-12-06 version).

If you want or need to install a newer version either use the eeprom recovery image or download the pieeprom file from github and run "rpi-eeprom-update -f your-pieeprom-file.bin" (the latter will preserve the bootloader config).

Configuring the fan trip-points is currently not possible but RPi folks might add that in the future.

I've also opened an issue about the fan running full-throttle at bootup (which I personally find rather annoying) - let's see if that will be changed in the future

We've just merged the fix https://github.com/LibreELEC/LibreELEC.tv/pull/8402 it'll be included in the next nightly build.
