Hi, thanks for answering. When we use gst-launch we get the correct video both with x-raw-rgb and x-raw-yuv, but with yuv we also have to set the width and height.
We have tried both of them in Matterhorn, but then they both turn green. We suspect that the **capture.device.BT878_input0.src=/dev/video0** line overrides the customProducer-line since all the results are the same as when we don't include the customProducer-line.
