No video to QGroundControl from a RPI webcam

[patrickelectric (Patrick José Pereira)]

Right now, this is how companion are using gstreamer to send the video to QGC.

Using Blue Robotics Low LIght USB cameras in ROV system

gst-launch-1.0 -v v4l2src device=$DEVICE do-timestamp=true ! video/x-h264, width=$WIDTH, height=$HEIGHT, framerate=$FRAMERATE/1 ! h264parse ! queue ! rtph264pay config-interval=10 pt=96 ! udpsink host=192.168.2.1 port=5600 Change the device, width, height, framerate, and client ip/port as necessary for multiple streams. You should do a bandwidth test because other factors like power supply and cable/connector quality/disrepair can affect video quality.

But, for this pipeline, it’s necessary a camera that output h264, you can check your camera output formats with:

v4l2-ctl -d $DEVICE --list-formats

Than, you’ll be able to check the gstreamer pipeline and correct it if necessary.
