Hi Randy, We also experienced this issue. One of the changes in the v4l2 core affected the MFC driver. A fix for MFC has been prepared by Marek Szyprowski and should be sent out soon. Also another tip - in 3.13 a check on bytesused and length fields in planes array has been implemented. So make sure to set them appropriately.
