Hi
I am trying to get imxv4l2videosrc to work on i.MX7 with ov5640. Anyone having
success with this setup?
I get this kind or error log:

dmesg shows:

Looks like imxv4l2videosrc tries to use "I420" pixel format but that is not
supported by mx6s-csi driver? Something wrong with caps negotiation?
imxv4l2src works fine.
