Using custom camera in OpenCV (via GStreamer)

Question

I\'m using Nitrogen6x board with ov5640 camera(mipi).

The camera is not using standard v4l/v4l, but we can stream video using GStreamer for its driver (mfw_v4l):

Answer 1

Looks like we can call the camera using a proper GStreamer pipeline like below:

VideoCapture cap("mfw_v4lsrc ! ffmpegcolorspace ! video/x-raw-rgb ! appsink")

as the camera output is in YUV, we need to convert that to RGB to pass the frames to OpenCV. This is where OpenCV makes sure it gets RGB colorspace.
