i.MX6ULL-EVK with OV5640
------------------------
On this platform a parallel OV5640 sensor is connected to the CSI port.
The following example configures a video capture pipeline with an output
of 640x480 and UYVY8_2X8 format:
.. code-block:: none
# Setup links
media-ctl -l "'ov5640 1-003c':0 -> 'csi':0[1]"
media-ctl -l "'csi':1 -> 'csi capture':0[1]"
# Configure pads for pipeline
media-ctl -v -V "'ov5640 1-003c':0 [fmt:UYVY8_2X8/640x480 field:none]"
After this streaming can start:
.. code-block:: none
gst-launch-1.0 -v v4l2src device=/dev/video1 ! video/x-raw,format=UYVY,width=640,height=480 ! v4l2convert ! fbdevsink
.. code-block:: none
# media-ctl -p
