[meta-freescale] imxv4l2videosrc problem with i.MX7

[Ari Sinisalo]

I am using NXP Sabre i.MX7dual.

It should work fine with the ov5640. What board is this?

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
