You can simply write to /dev/console. eg try this as autostart.sh:

( 
echo -n "waiting"
for i in `seq 1 10` ; do
  echo -n "."
  sleep 1
done
echo "done"
) > /dev/console

You can follow the master branch on github GitHub - LibreELEC/LibreELEC.tv: Just enough OS for KODI or the LE release posts.

If RPi kernel is bumped to 5.10.30 or newer it'll have the initial composite patches.

But note that the composite change is pretty new, probably incomplete and/or needs additional configuration - I haven't tested that myself yet (my TV doesn't have analog video inputs so I have to leave that to someone else).

Composite video output isn't fully implemented yet in the new graphics driver.

Some initial support was recently included in the RPi kernel but these changes aren't available in LibreELEC builds yet - the latest RPi kernels introduced some regressions and we are waiting for these to be fixed before we include the update in LE.

Glad you finally found the culprit!

USB can be "fun", there are ton of odd devices out there, and especially audio (and video/webcam) devices can easily break if other devices consume too much bandwidth. Which is probably what the keyboard is doing (for whatever reason, probably because it has a somewhat broken USB configuration...).

Hi Hias, can I run something similar under RPiOS but with 96kHz/24-bit, to check if it's working?

Just change the "-r" option (that's the samplerate), eg to "-r 96000". "-F" set's the format, use "-F S16_LE" for 16bit, "-F S24_3LE" for 24bit. The buffer and period time parameters ("-b", "-p") are probably not important, I think you can drop these.

I suspect the issue is very specific to your USB DAC in combination with the RPi4's USB controller. If you can reproduce that on stock RPiOS you might have a chance that one of the RPi devs looks into it - not much I can do about it.

The latest 0.5.3 release of the inputstream helper addon contains a temporary fix which will download a working widevine version - see Release v0.5.3 · emilsvennesson/script.module.inputstreamhelper · GitHub

It looks like it's available in kodi 19/Matrix addon repo, but not 18/Leia. So on LE10beta an addon update should do the trick, on LE9.2 you have to download and install the zip manually. Then kick off a widevine download/update in the inputstream helper addon.

These log lines

look like inputstreamhelper installed a new widevine library yesterday and now it's broken.

You could try reinstalling it in the inputstreamhelper addon or force an update.

Updating widevine is a bit like russian roulette... I had quite a lot of similar "fun" back then when I used netflix on RPi...

RPi3 on LE9.2 uses the old graphics stack (firmware driver). RPi3 nightly LE10 builds (currently pre-alpha) need that, too.

Yes, this is expected - RPi needs to be able to read the EDID from your TV.

You can run "getedid create" to make the EDID permanent - then it's safe to power on your TV later.

I kinda succeeded having a 4K output. But the still 1080p UI was stuffed into the upper left quarter of the screen.

You need to restart kodi / reboot LibreELEC then it should work (it's also mentioned in the info line of the GUI size limit option).

Quote from elonesna

Sorry if I don't agree with you. SSH, SFTP, and VNC are the three must-have tools for handling an unattended remote device. The inability to use VNC is a major reason not to buy a device.

I'm not saying VNC isn't useful but the simple fact is that there doesn't exist a VNC server for the currently used graphics stack - it has to be written first.

Which LibreELEC version are you using?

On LE10beta 4kp60 output isn't implemented yet (it's currently being worked on).

LE 9.2.6 supports 4kp60 if you add hdmi_enable_4kp60=1 to config.txt and enable "ultra hdmi deep colour" (or some similarly named option) for the HDMI port in you TV's settings.

The GPU in RPi4 is a bit underpowered for 4k rendering therefore GUI resolution is limited to HD. You can disable the limit in settings->system->display (you need to switch level to expert to see it) but then GUI navigation will be quite slow - I wouldn't recommend doing that.

Actually it's best to change the display resolution to HD (in general your TV will do better HD->4k upscaling than kodi/rpi) and enable 4k modes for video playback in the whitelist.

If you run RPi(4) then the answer is no. dispmanx vnc no longer works with the new graphics driver so it was removed from addons.

As an alternative you can enable kodi's webserver, you can configure and control quite a lot of things with it.

I haven't used the Netflix addon for ages, but back then when I did IIRC it worked just fine with hyperion so I couldn't reproduce the issues so not quite sure what caused that. ISTR adjusting the grabber resolution (to 512x512 or sth like that) fixed that - just use the forum search function and you should find tons of info about that.

By the way, lzo is used for compression for LE9.2.x, why use zstd instead of LE10? Should the compression quality be more efficient?

Yes. Decompression speed is about the same, but compressed size is smaller.

Hias

Ah, and I probably should add that it's very likely you'll have the same screen blanking issues at 4k output with the LE hyperion addon - these are general issues of the screen grabber used by hyperion.

Hmm, I fixed that issue almost 2 years ago but it seems the fix wasn't merged... You can find the link to a working build in the github PR here: update to latest upstream version, fix exception with JRE >= 9 by HiassofT · Pull Request #4 · LibreELEC/hypercon · GitHub

Sorry, no idea.

The RPiOS showed the same bandwidth error in dmesg so it'z puzzling why it would work on RPiOS but not LibreELEC.

Might be worth checking if Kodi on RPiOS shows the same issue (but IIRC there are only older Kodi 18 versions available for RPiOS).

Or you could try the latest LibreELEC nightly, it enables USB autosuspend (which was accidentally disabled before).

If you use a current nightly build and have a 4k TV you probably need to add "force_turbo=1" to config.txt as the latest RPi kernel introduced an issue with 4k output that can lead to "no signal" on TV (we are currently waiting for a fix for that).

so long,

Hias
