For our application we use two video streams from two different camera interfaces like below.
1. ADV7610 -> parallel CSI -> IPU
2. tw6869 -> pcie -> IPU
To support zero copying, both video streams are captured through imxv4l2videosrc of gstreamer. However I have only one v4l2cap node in dts file which is being utilized for parallel csi bus :
compatible = "fsl,imx6q-v4l2-capture";
ipu_id = <0>;
csi_id = <0>;
mclk_source = <0>;
mipi_camera = <0>;
default_input = <1>;
status = "okay";
should I need two nodes to achieve simultaneous video streams ?
