Subject: [PATCH v2 2/4] media: imx.rst: Provide an example for unprocessed video capture
Date: Thu,  9 Apr 2020 13:29:43 -0300	[thread overview]
Message-ID: <20200409162945.3559-2-festevam@gmail.com> (raw)
In-Reply-To: <20200409162945.3559-1-festevam@gmail.com>

The current example for imx6q-sabresd is for a direct conversion pipeline.

Provide an extra example using unprocessed video capture for completeness.

@@ -644,6 +644,26 @@ CSI-2 OV5640 has been tested, so the OV5642 node is currently disabled.
 The OV5640 module connects to MIPI connector J5 (sorry I don't have the
 compatible module part number or URL).
 
+The following example configures unprocessed video capture pipeline to
+capture from the OV5640, transmitting on MIPI CSI-2 virtual channel 0:
+
+.. code-block:: none
+
+   # Setup links
+   media-ctl -l "'ov5640 1-003c':0 -> 'imx6-mipi-csi2':0[1]"
+   media-ctl -l "'imx6-mipi-csi2':1 -> 'ipu1_csi0_mux':0[1]"
+   media-ctl -l "'ipu1_csi0_mux':2 -> 'ipu1_csi0':0[1]"
+   media-ctl -l "'ipu1_csi0':2 -> 'ipu1_csi0 capture':0[1]"
+   # Configure pads
+   media-ctl -V "'ov5640 1-003c':0 [fmt:UYVY2X8/640x480]"
+   media-ctl -V "'imx6-mipi-csi2':1 [fmt:UYVY2X8/640x480]"
+   media-ctl -V "'ipu1_csi0_mux':0 [fmt:UYVY2X8/640x480]"
+   media-ctl -V "'ipu1_csi0':0 [fmt:AYUV32/640x480]"
+
+Streaming can then begin on "ipu1_csi0 capture" node. The v4l2-ctl
+tool can be used to select any supported pixelformat on the capture
+device node.

 The following example configures a direct conversion pipeline to capture
 from the OV5640, transmitting on MIPI CSI-2 virtual channel 0. It also
 shows colorspace conversion and scaling at IC output.
