Tool/software:
Hello Team,
I am using below command to get image data from sensor.
gst-launch-1.0 -v v4l2src device=/dev/video-rpi-cam0 io-mode=dmabuf-import ! video/x-bayer, width=1920, height=1200, framerate=60/1, format=rggb10 ! appsink
In above command getting error:
ERROR: from element /GstPipeline:pipeline0/GstV4l2Src:v4l2src0: No downstream pool to import from.
Additional debug info:

In above command if I use io-mode=dmabuf instead of io-mode=dmabuf-import than it's working.
Can you please guide me what is the issue here.
We have observed if we used dmabuf-import in that able to achieve fps instead of dmabuf. so, Can I use dmabuf-import in above command ?
Thanks,
Jaimin
