v4l2: Extend device caps with V4L2_CAP_STREAMING
This capability tells the application that mmap() is supported. GStreamer would return an error saying there there is no input/output method supported by this device otherwise. This was tested with: LD_PRELOAD=$(pwd)/build/src/v4l2/v4l2-compat.so GST_DEBUG="v4l2*:7" gst-launch-1.0 v4l2src ! videoconvert ! autovideosink With this patch, GStreamer will reach playing state. It then blocks waiting on poll() which is not implemented yet on our side.
