CRITICAL ERROR: Failed to set crtc: Permission denied

uwe.hentzschel · January 26, 2021, 10:14pm

It’s my first try on RPI4. I have downloaded https://info-beamer.com/jump/download/player/info-beamer-pi-1.0.1.b40a5f-buster-fkms.tar.gz and use ’ info-beamer -install-hevc’.
Wenn start info-beamer like:

./info-beamer samples/image

I got this error:

The log output isn’t sufficient to figure out what might be going on. Can you run info-beamer with the environment variable INFOBEAMER_LOG_LEVEL=3 set? This will produce a more verbose output that might help.

uwe.hentzschel · January 26, 2021, 10:39pm

Thank you for your interest! He is the log file.

Can you check /boot/config.txt? Maybe you have

dtoverlay=vc4-kms-v3d

in there. This mode (Full KMS) is currently not supported. Only Fake KMS is for now. For that, the line must be:

dtoverlay=vc4-fkms-v3d

If that’s not it, we might try another video mode.

uwe.hentzschel · January 27, 2021, 6:18am

These are the entries in config.txt.

[pi4]
# Enable DRM VC4 V3D driver on top of the dispmanx display stack
dtoverlay=vc4-fkms-v3d
max_framebuffers=2

[all]
dtoverlay=vc4-fkms-v3d
gpu_mem=256

What video mode can i try now?

infobeamer-fw · January 27, 2021, 3:05pm

You can try to start info-beamer with environment variable

INFOBEAMER_PRIMARY_MODE=6

This should set 1920x1080 - see the line in your previous output:

 [surface.c] 6, 1920x1080: 60.00Hz name: 1920x1080, clock: 148500 (flag:0xa nhsync nvsync)

If that also doesn’t work, you might try:

INFOBEAMER_DRM_DEVICE=/dev/dri/card1

If neither helps, I’m beginning to run out of ideas. Is that a fresh RaspbianOS install using the latest release?

uwe.hentzschel · January 27, 2021, 7:59pm

Yes that is the latest and greatest version of RaspbianOS.
Sorry but both versions bring the same bug.
A the moment i have a RPI3 but how can i help to solve the problem?

infobeamer-fw · February 2, 2021, 11:38am

I’ll run info-beamer on a recent Raspberry Pi OS to see if I can reproduce the issue.

uwe.hentzschel · February 2, 2021, 3:16pm

Cool - Thanks ! I hope the mistake are not in front of the notebook.

infobeamer-fw · February 2, 2021, 3:18pm

Got it running: I’ve installed the latest lite OS release. I then installed the required dependencies (some missing in the included info-beamer README.txt. I’ll add them):

apt-get install libdrm2 libgbm1 libgles2-mesa libegl1-mesa \
                libevent-2.1-6 libavformat58 \
                libpng16-16 libfreetype6 libavresample4

The included samples in samples all work correctly. What doesn’t work at the moment is HEVC decoding: I guess the constant reworks to include HEVC decoding into the official FFMPEG release and exposing the decoder using the official V4L2 (video 4 linux 2) API broke the approach used in info-beamer. This is something that needs to be handled in some future release, but I’m getting tired of the current sad state of HEVC on the Pi4. I’ll wait for an official announcement before touching this undocumented pile of **** again.

Meanwhile, the most likely reason it didn’t work for you is that you have X running somewhere. Reason for that is, that only one process can be DRM master. When you run X, it gets exclusive access and info-beamer gets “Permission denied” when trying to open the display. I guess the error message should be improved. I’ll see what I can do.

uwe.hentzschel · February 2, 2021, 3:34pm

I will try the Raspberry Pi OS Lite tonight.

infobeamer-fw · February 2, 2021, 3:36pm

Improved the error message for a future release: You’ll then see:

[main.c] root node is shader
[main.c] It looks like you only have 76MB of GPU memory reserved.
[main.c] Please provide at least 192MB. See the README.txt on how to do this.
[surface.c] info-beamer is not DRM master, but needs to be.
[surface.c] Most likely reason is that you have X running.
[surface.c] Terminate the X server and try again.
CRITICAL ERROR: Cannot setup DRM device(s)

uwe.hentzschel · February 2, 2021, 8:28pm

Great - I used Raspberry Pi OS Lite. As an example I tried https://github.com/verschwoerhaus/info-beamer-vsh.git and everything is perfect. I’m from rpi3 and X hasn’t been a problem so far. I learned something. Thank you!

infobeamer-fw · February 2, 2021, 9:24pm

That package also perfect works using info-beamer hosted using Add package and entering its github url. No need to mess with Raspberry Pi OS
