@LR If you just want to change the camera that is streaming then modify /etc/modalai/voxl-streamer.conf to specify the desired camera. If you want to stream two or more cameras then you need to start a voxl-streamer instance for each one and specify a different port for each one. Then use voxl-mavcam-manager to inform QGC of the availability of the multiple streams. See https://docs.modalai.com/voxl-mavcam-manager/
