I built a custom hardware platform in Vivado 2020.2, using the HDMI 1.4/2.0 ReceiverSubsystem (with Evaluation License, if that makes any difference). To build Petalinux I'm using Petalinux tools 2020.2
Now I tried to set up a GStreamer pipeline in Petalinux, but something is wrong with the V4l2 drivers it seems to me. /dev/vid0 is not available. Here are the steps I took:
In petalinux-config -c rootfs I added packagegroup-petalinux-gstreamer and packagegroup-petalinux-v4lutils.
Question: do I need to add anything else?
In the Petalinux project folder I added the following lines to project-spec/meta-user/recipes-kernel/linux-xlnx/bsp.cfg
That's how I interpreted the "Kernel Configuration" sections in
I also read multiple times, that there might be issues in the automatically generated device tree, but I really don't know how it is supposed to look like, so I attached an Image of my Hardware-Design and the device tree file generated in components/plnx_workspace/device-tree/device-tree/pl.dtsi (had to change the name to pl.txt to upload it)
Thank you in advance for your help

Did you make sure whether it has a capability to capture video stream on your media graph ?
Also, did you set proper parameter on media graph ?
I'm probably sure that there is not capability with current setting on your media graph.
Would you make sure it ?
