whats the output of :

 v4l2-ctl --device=/dev/video1 --all

and :

 v4l2-ctl --device=/dev/video0 --all

commonly v4l2 drivers have multiple associated nodes, with different capabilities. You could be using the wrong one

it looks like maybe your rockchip isp isnt setup. Its been a while since ive done it on rockchip.

https://www.kernel.org/doc/html/v5.17/admin-guide/media/rkisp1.html

fundamentally, after your ISP is setup, your v4l2 device should be usable without v4l2rtspserver

$ gst-launch-1.0 v4l2src --device=/dev/video0 ! videoconvert ! autovideosink

this should give some type of video stream. once that works, the rtsp server should work too
