when trying to combine a picture and video (using imxv4l2src ) using the imxcompositor_g2d we get very poor framerate. 5% resources are shown with "top".
using the same pipeline while using a filesrc (video) instead, the framerate is as expected with the same resources used.
The only reason I could see is that the camera source outputs the frame in interlace-mode=interleaved, which seemingly is not supported by the imxcompositor_g2d.
When connecting the same camera source to the sink element, the video looks perfect.
The input to the camera interface is UYVY 1280X720 16bit interface.
