using edge with several cameras and the video downlink works fine, but not with the Workswell WIRIS thermal camera. Any idea what happens there? Can i test the video downlink directly with gstreamer? If yes, which gstreamer parameters shell I use? Also tested it with several cables and HDMI monitors - the cam and the cables are ok.
For a start you can ssh to Edge and try simple raspivid -cs 0. It should exit without any errors.
To test with gstreamer you can use something like this: gst-launch-1.0 rpicamsrc camera-number=0 bitrate=3000000 keyframe-interval=30 preview=false use-stc=false ! video/x-h264, framerate=0/1, width=1280, height=720, profile=high ! h264parse ! rtph264pay name=pay0 pt=96 config-interval=5 ! udpsink host=127.0.0.1 port=5600
