I have tried to use imxv4l2videosrc but it fails constantly. Following is what
I get with fakesink.

Should imxv4l2videosrc work with i.MX7 and OV5640?
I can get camera capture working with freescale plugin. These work fine:
gst-launch-1.0 imxv4l2src device=/dev/video1 ! fakesink
gst-launch-1.0 imxv4l2src device=/dev/video1 ! imxv4l2sink
gst-launch-1.0 imxv4l2src device=/dev/video1 ! imxpxpvideosink
