LibreELEC (Leia) 9.2 ALPHA1 with Raspberry Pi 4B Support

Quote from Jasjeet

I’m on the 002 build now, still getting tearing in the UI, was that not fixed yet?

Apperently not.

I have also tearing on 002.

Yes, The tearing is still there on latest build.

Hej all,

I installed LibreELEC-RPi4.arm-9.1.002.img.gz on my Pi 4 (4GB RAM).

The playback of video starts, but it only plays the sound. The video itself stays black.

Any ideas why this is happening?

Cheers,

I have a strange behavior when i use the Simple Iptv client.

First the FPS from the Stream is at 50, after 2sec i goes to 25 and after additionally 2sec i goes to 12,5.

Im on the newest Alpha Build.

When i come home i will attach an log.

Here is the log for the 50fps to 25fps Video Stream switch.

These 2 lines are the problem i think:

CalcFrameRate framerate was:50.000000 calculated:25.000000

CMMALRenderer::Configure - 1920x1080->[email protected] flags:1 format:-1 orient:0

Is there a setting i can run to stop CMMALRender switch fps rates?

Hi

If you plug your cable on HDMI1 you will not get the video. It's on HDMI0

Quote from HiassofT

there won't be any RPi4 testbuilds for a while.

That's understandable. The .002 build works quite well. Nevertheless curious as I am I made another image from the Github source. It boots and it's even running on Linux kernel 5.1.8 so that's quite amazing. However instead of scaling down the image my 720P tv shows only the upper left portion of the HDMI output when the Pi4 is set to 1080p. Other builds I made in the past few weeks had the exact same issue. The official test builds work fine though. Is there a reason why all builds straight from Github show this behavior? Is there something I can do with these builds that fixes the HDMI output so that my TV receives the entire output?

Indeed - Thanks for the hint!

OMG! Thanks this has been a PITA for the last week. Upgrade from Alpha 1 to Alpha 2 must have coincided with me changing input, couldn't for the life of me figure out why video wasn't playing after the upgrade.

I've got the same problem before

And yes it's strange but hdmi0 get the video hdmi1 get kodi interface but no video.

So I updated a RPi 3b from LibreElec Addon from 9.0.2 to 9.1.002 and it starting acting weirdly...went to safe mode many times and got over 2000 crash logs in a week..

Addons don't respond and couldn't connect in any way to the Rpi.

Main error I could see in every log is this :

2019-08-03 11:20:34.362 T:1937531456   ERROR: failed to create window surface (EGL_BAD_NATIVE_WINDOW)
2019-08-03 11:20:34.362 T:1937531456   FATAL: CApplication::Create: Unable to create window

2019-08-03 11:20:34.720 T:1937531456   ERROR: eglSwapBuffers failed (EGL_SUCCESS)
2019-08-03 11:20:34.720 T:1937531456   ERROR: Exception in CApplication::Cleanup()

This is a headless Rpi being used as a TvHeadened server with RPi TVHat attached..

Only addons installed are VNC,Tvheadend Server/HTSP Client and Emby4.

Please understand this is far away from my home so it's bit hard for me to try certain things.

Any Help appreciated..

9.1.002 is RPi4 not RPi3

Not Really..

I got a Rpi 2 running nicely on 002

Can you try enabling hdmi_force_hotplug=1 in config.txt? Looks like kodi is having troubles with composite video mode (which is default if no HDMI device is connected).

so long,

Hi thanks for your reply...to be honest I had a hard time to roll back to 9.0.2 as the addons I have installed where updated to work with 9.1.002 and after I reinstalled 9.0.2 again the addons didn't downgrade and I lost VNC connection...

Anyway now I am back on 9.0.2 and all is working fine..

I would like to try what you suggested but perhaps I will try to replicate issue on my other RPi at home so I can fix quickly if something goes wrong as the Rpi in question is 3000km away from home with no tv attached to it...so got to do everything through ssh and vnc so hardwork..

Maybe someone else who got same issue can try this...

Hello all,

Taking chance of free time, and willing to test the new PI4 with Libreelec I am happy to see a positive and impressive results on my own system : PI4 2 Gb + Hifiberry DAC+ +NAS database access : works with a much reactive system vs by RPI3B+

At the moment I confirm the heat is significantly higher than my P3 B+, and considering it is yet not in any case (unavailable here in Paris area, for such a config) I am sure it will get worst once fully packed...

I am currently seeing temp btw 70 and 75°C (for 25¨° in the room) ... so close to the 80° limit I heard about.

I have seen and read that the new firmware update from Rasp team is allowing up to 6 deg decrease so I wonder if this is something I can implement over the current Libreelec version I am running : "LibreELEC (Leia) 9.2 ALPHA1 with Raspberry Pi 4B Support"

I have to say I am very rooky when it matters to dig with Linux systems, but am able to access to my Rasp through SSH. Therefore my question is how can I get the proposed new firmware update in my Rasp system ? I can see how to do the update from the downloaded zip file, but I am unable to get it downloaded from the web when in SSH mode.

Hope I am clear enough ...

Thanks

I have not updated my firmware and I had same temps as you before I added a small 40mm fan on top of the pi.

My idle temps are now around 34-42 C depending on the room temperature.

I've read some various reports about the firmwares pros and cons and decided not to update for now.

The fan is doing a great job and i can only hear it if i put my ear close to it.

Hello Sanity,

Thanks for your comments. Understood your option. Would you share how does it looks like ? Which type of casing, and fan, power supply ?

Thanks

Hey,

At the moment I don't use a case for it. There were none availible when i bought my pi4

The fan is just a noname that I had spare and I have just put it on top of the pi for now. The power supply is a original one.

I'll buy a case as soon as I can find one and it will prolly be a larger case cause I believe that I always need a fan to keep decent temperatures!
