Hi,
I am using the below command to stream my camera in torizon-core 6.5 but command is returning the following error
gst-launch-1.0 v4l2src device=/dev/video3 ! “video/x-raw,width=2592,height=1944” ! fpsdisplaysink video-sink=waylandsink text-overlay=false sync=false -v
error:
gstwaylandsink.c(333): gst_wayland_sink_find_display (): /GstPipeline:pipeline0/GstFPSDisplaySink:fpsdisplaysink0/GstWaylandSink:waylandsink0:
Failed to create GstWlDisplay: ‘Failed to connect to the wayland display ‘(default)’’
Setting pipeline to NULL …
Freeing pipeline …
Where as with v4l2-ctl I’m able stream the camera. I’m also able to stream the camera using gstreamer with torizon-multimedia reference image but unable to do so in torizon-core-6.5
Greetings @sapthagiri,
I just tried this with a USB camera, using a similar pipeline command:
gst-launch-1.0 v4l2src device='/dev/video4' ! "video/x-raw, format=YUY2, framerate=5/1, width=640, height=480" ! fpsdisplaysink video-sink=waylandsink text-overlay=false sync=false
It worked fine on my side. The error you are getting here:
Failed to create GstWlDisplay: ‘Failed to connect to the wayland display ‘(default)’’
Did you create a Weston container prior to starting your gstreamer pipeline as instructed here: How to use Cameras on Torizon | Toradex Developer Center

Hi @jeremias.tx ,
I tried with USB camera and issue still persists.
Yes I ran weston container using below command
docker run -d --rm --name=weston --net=host --cap-add CAP_SYS_TTY_CONFIG -v /dev:/dev -v /tmp:/tmp -v /run/udev/:/run/udev/ --device-cgroup-rule=‘c 4:* rmw’ --device-cgroup-rule=‘c 13:* rmw’ --device-cgroup-rule=‘c 226:* rmw’ torizon/weston:$CT_TAG_WESTON --developer --tty=/dev/tty7
the weston container launched without any issue.
What device are you on? I tried both with iMX6 and iMX8 and it works with my USB camera.
Also the gstreamer container are you building it as described here?: How to use Cameras on Torizon | Toradex Developer Center

Hi @jeremias.tx ,
I’m using a verdin with the evaluation board. Im using the attached docker file for gstreamer and compiling my gstreamer application. Note: i’m not using my gstreamer application to stream the camera but the standard gstreamer command.
Dockerfile.bsp5 (1.1 KB)
How did you construct this Dockerfile? You have 2 FROM statements. Your source images in the FROM statements are using the 1 tag which are not for Torizon OS 6.X and are 3 years old.
I would recommend reconstructing your Dockerfile using this sample as a reference: torizon-samples/gstreamer/bash/simple-pipeline at bookworm · toradex/torizon-samples · GitHub

Hi Jeremias,
I was able to get stream by modifying the docker file.
Now I have a different issue . I have modified the dockerfile to compile my gstreamer application, Im receiving below error while building the docker file, the same commands worked for IMAGE_TAG 1
Building dependency tree…

I was able to get stream by modifying the docker file.
Glad to hear!
Now I have a different issue .
The issue here is due to a weird dependency chain around libgtk-3-dev. To get around this you want to apt-get install the imx-gpu-viv-wayland-dev package before libgtk-3-dev. Then the package dependencies should work out.

Jeremias
