i.MX6 video capture to GPU buffer

Is there an existing mechanism to capture video (V4L) frames directly into a buffer which can also be directly accessed (without additional copies) by OpenCL?

 

I have explored the use of V4L2_MEMORY_USERPTR buffers for the camera access, but this functionality does not appear to be working [dequeued buffers do not match those which were enqueued]. The example provided in https://community.freescale.com/thread/359579 fails when run with the "-u" option, on 3.10.17-1.0.2_ga
