[meta-freescale] imxv4l2videosrc does not work with i.MX7

[Joonas Tanskanen]

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.
