LibreELEC-RR [ Brave | Spotify | Moonlight | Emulationstation | Retroarch | Pegasus ]

Quote from Cillit

Hi there,

first of all I would like to thank you for this build. It's really nice to have moonlight-qt and xpadneo as part of libreelec.

I have got a little problem with moonlight. On 1080@60 i noticed some flickering in the upper third of the screen, especially if there is a lot going on, if nothing happens on the screen the flickering is not noticeable. I tried with v-sync on/off and forced h.264. While v-sync seems to make no difference, forced h.264 makes the flickering worse.

Greetings,

Cillit

Edit: If moonlight starts, the TV resolution switches to 4k@30, if a game stream starts the resolution still is at 4k@30, even if the streaming is set for 1080@60 inside moonlight. I have tried to force a resolution with the hdmi_mode solution mentioned in the wiki.

Hi Cillit, next weekend i'll test the new Build, i couldn't make it before, and give some feedback.

Hi there,

I don't think this is a moonlight issue. I did a little bit of research in the forum and it seems like the global resolution is now configured with cmdline.txt, which also has a new syntax. I tried different options, but had no sweeping succuess, yet.

I tried

video=HDMI-A-1:1920x1080@60D

and

drm.edid_firmware=HDMI-A-1:edid/edid-HDMI-A-1.bin video=HDMI-A-1:1920x1080D

but it didn't work. A hint from this thread:

Post

RE: LE 10 RPi2 nightly: no hdmi output

you are right. the cmdline.txt was wrong.

i have -restarted the configuration procedure

first i had deleted the wrong entries (this was the default entry for my rpi2)

LibreELEC:~ # cat /flash/cmdline.txt

boot=UUID=1107-2955 disk=UUID=27ea94ba-c897-4e07-942f-594aaf01c537 quiet

then i had recreated the edid file

LibreELEC:~ # getedid create

successfully installed edid override for HDMI-A-1

after that the cmdline was modified by the getedid command

LibreELEC:~ # cat /flash/cmdline.txt

boot=UUID=1107-2955…

made me try:

drm.edid_firmware=HDMI-A-1:edid/1920x1080.bin video=HDMI-A-1:D

This finally worked, no more tearing and exellent streaming quality, but it killed CEC and HDMI audio, also the picture is slightly darker.

Maybe there is a better solution.

Edit: Yes its a Rpi4.

Hi Cillit, i've checked, yes, you're correct, while i could follow the guide on the Wiki and force Kodi into the desired resolution, Moonlight (and probably the QT apps) doesn't respond to this forced res.
Also can confirm on the streaming glitch.
Didn't tried on your (somewhat) working method, and i'm short of time to try right now but you've narrow a lot of options. :-S

Hi,

i have done a clean install of 10RC1. I have connected a Logitech K380 Bluetooth Keyboard using "Trust and Connect".

I found the following problems:

- Sometimes after clicking "Trust and Connect" Kodi (not LibreELEC) performs a restart.

- After every restart, the connection is lost until I start the discovery on the keyboard and click connect in the LibreELEC Bluetooth menu.

- If i use "Pair" from the LibreELEC Bluetooth menu, the following window prompts me to press Keys witch aren't shown.

I hope you can help me.

Hi,

here are some logs with

video=HDMI-A-1:1920x1080@60D

setting. As soon as moonlights starts the resolution switches to 4k@30.

Just wanted to say a big thanks for this build! Been trying to get various combinations of RetroPie/Kodi/RetroPlayer to play nicely together and this just makes the whole thing easier. Plus PCSX-rearmed actually works in this build which it doesn't on the standard Kodi 19 build. Great work!

One quick question. How do I set the resolution of RetroArch? it's defaulting to 4k and the output options seem to have been disabled or some such.

EDIT... found this in the wiki.

I've checked the wiki and used the RR-Config app to configure audio, but it doesn't matter if i use ALSA or PA, no audio works in retroarch.

I've also noticed now that no audio us working on rpi4 via retroarch. it looks like the audio driver cannot load.

I've actually got audio working now on the RPi4 by using SDL2 as the output in RetroArch and ignoring the wiki post to use RR Configuration tool. I've logged a bug in case SDL2 can be added as an output option. Or perhaps theres a missing driver from the build.

Hi,

I've just set up a brand new NUC with a Tiger Lake CPU/iGPU (1165g7) and I'm not having much luck with anything that requires GL graphics.

glxinfo provides:

name of display: :0.0

Error: couldn't find RGB GLX visual or fbconfig

I found this: https://forum.libreelec.tv which I thought might have something to do with the solution, so I compiled LE RR 10 from source with 5.11.22 but still the same issue.

I'll keep trying at it but thought I'd point out the issue and see if there's something simple that I might be overlooking?

Thanks

Hi glennguy the 5.10 LE works (ish) Though there are issues until you get to 5.12. I am running 5.14 on my NUC11 - though not doing any RR stuff. 5.14 will PR to nightly shortly, and there are a number of intel and mesa updates in nightly.

Thanks heitbaum, I'll keep an eye out on upstream and try the master branch in RR with 5.12/13/14 and report back.

Sounds good, is there an update channel yet or a way to update without a reflash? The old nightly repo is still on 9.x.

I've tried building from SupervisedThinking/master-rr-westmere which is running media-driver 21.3.1 and mesa 21.2.1 but no luck, same issue.

Also tried updating kernel to 5.12.19 but I ran into a bunch of issues with the packages. Fixed some but got stuck on getting crazycat to build.

Quote from SupervisedThinking

Just download the .tar file stored in testing, copy it to the update folder & reboot your RPi4

Have updated to the latest build and there's still no audio with ALSA or Pulseaudio on the RPI4 within retroarch. All emulators show the same error:

ALSA

[ERROR] [ALSA]: Failed to initialize...
[ERROR] Failed to initialize audio driver. Will continue without audio.

Pulse

[ERROR] Failed to initialize audio driver. Will continue without audio.

The rr-config tool seems to have no effect on anything. The retroarch settings remain unchanged after I switch from alsa to pulse and vice versa using the RR config tool.
