There are several steps to configure a gstreamer v4l2src stream-mmap:
Install the necessary packages: Install gstreamer and v4l2loopback modules.
Create a virtual camera device: Use the v4l2loopback module to create a virtual camera device. This can be done by running the following command:
sudo modprobe v4l2loopback devices=1
This will create a new camera device, usually /dev/video1.
v4l2src ! video/x-raw,width=640,height=480,framerate=30/1 ! videoconvert ! video/x-raw,format=I420 ! videorate ! video/x-raw,framerate=30/1 ! v4l2sink device=/dev/video1
Note: The steps above will create a virtual camera device and stream video from it using the v4l2src element. In order to use this stream in other applications, you will need to configure the applications to use the virtual camera device. Specific steps for doing this will vary depending on the application.
