Nvarguscamerasrc - Error NotSupported: Failed to load EGL library

Hi everyone,

I’m actually trying to acquire images and videos from a camera with the Jetson Nano and Gstreamer. I also want to have the lighter embedded Linux system and use Buildroot.

On this buildroot I installed everything needed to run the Nvarguscamera plugin (packages, drivers and multimedia API). The cross compilation goes fine and my plugin is not blacklisted by Gstreamer.

I have to launch the daemon:

$ nvargus-daemon &

And then the nvarguscamera plugin :

$ gst-launch-1.0 nvarguscamerasrc ! fakesink

But I have this error message :

Setting pipeline to PAUSED ...
Pipeline is live and does not need PREROLL ...
Setting pipeline to PLAYING ...

Despite having EGL libraries installed in the /usr/lib/ repertory.

Does anyone have an idea of where this error message come from ?

Check below doc to confirm the sensor driver configure without any problem first.
For the EGL have below command before gst-launch-1.0

export DISPLAY=:0

Hi ShaneCCC,
Thanks for your answer.

The V4L2-compliance test results with 43 succeeded tests (with some “OK (Not Supported)”) and 3 failed.

Also, when I’m trying to run a V4L2-ctl test I got this error message :

tegra_channel_status:error 20022 frame 0
tegra_channel_status:error 20022 frame 1
tegra_channel_status:error 20022 frame 2
tegra_channel_status:error 20022 frame 3
…

And have the export DISPLAY=:0 command doesn’t change my first error message with EGL library.

Enable the dev_dbg() in csi2_fops.c to check the status

6

What do I have to change in the csi2_fops.c file to enable the dev_dbg() ?

Try this command.

sudo su 
echo file csi2_fops.c +p > /sys/kernel/debug/dynamic_debug/control
