Tool/software:
Hey,
I would like to capture videos from the tc358743 connected to csi2. The driver is loaded and I get following media-ctl topology:
Media controller API version 6.6.32
Media device information
------------------------
driver j721e-csi2rx

Have anybody an idea how to capture the video?
