I am trying to use a basler camera on an IMX8m-plus board.
The camera is detected as:
root@ucm-imx8m-plus:~# v4l2-ctl --list-devices
():
/dev/v4l-subdev0
mxc-isi-cap (platform:32e00000.isi:cap_devic):
/dev/video0
FSL Capture Media Device (platform:mxc-md):
/dev/media0
And has the following capture modes:
root@ucm-imx8m-plus:~# v4l2-ctl -d /dev/video0 --list-formats
ioctl: VIDIOC_ENUM_FMT
Type: Video Capture Multiplanar
[0]: 'RGBP' (16-bit RGB 5-6-5)
[1]: 'RGB3' (24-bit RGB 8-8-8)
[2]: 'BGR3' (24-bit BGR 8-8-8)
[3]: 'YUYV' (YUYV 4:2:2)
[4]: 'YUV4' (32-bit A/XYUV 8-8-8-8)
[5]: 'NV12' (Y/CbCr 4:2:0)
[6]: 'YM24' (Planar YUV 4:4:4 (N-C))
[7]: 'XR24' (32-bit BGRX 8-8-8-8)
[8]: 'AR24' (32-bit BGRA 8-8-8-8)
Starting gst-launch-1.0 results in this output:
root@ucm-imx8m-plus:~# gst-launch-1.0 -v v4l2src device=/dev/video0 ! videoconvert ! videoscale ! videorate ! video/x-raw,framerate=30/1,width=320,height=240 ! autovideosink

No video is showing while this is active.
The videotestsrc is working perfectly fine. And the camera is working on different systems as well.

The system is an yocto-image (hardknott 5.10.72-2.2.0) from compulab. What do I need to change and/or test to display the camera stream correctly?
