=== 2x 1080p 60fps camera streams mixed to display (in-place=true) ===
'''Note:''' We only use one camera source that is splitted in two sources by a tee element. One of the video source input branches is flipped by 180 degrees, so the resultant image is a combination of the input image with the same image rotated.
