How to use gst-launch-1.0 to show v4l2src video, the sensor is configed as "mode_type = "bayer"; pixel_phase = "grbg";"

Hi,
This would need other users to share experience. Generally we capture YUV422 such as UYVY or YUYV through v4l2src. Don’t have much experience in capturing Bayer data through v4l2.
