I am currently using an Actioncam connected via an HDMI-CSI-Adapter to the CSI port as the primary
camera and an HT-301 Thermal Camera connected via USB as the secondary camera.
The CSI input is working and I have a rather stable stream from my actioncam.
For the thermal camera I followed the steps in the docs: https://openhd.gitbook.io/open-hd/advanced-setup/using-an-ip-or-usb-camera-as-second-camera
and saw that there is already a GStreamer line for the HT-301 in the settings file together with the wiki
saying that the HT-301 is well tested: https://github.com/OpenHD/Open.HD/wiki/Thermal-Cameras#hti-301-manufacturer-amazon
So I simply uncommented the line and rebooted the AirPi, but on the GroundPi nothing has changed.
Also changing to /dev/video0, video1, or video2 does not make a change.
I also have enabled the Picture in Picture function on the GroundPi but still nothing. Do I have to switch the feed somehow?
Interesting is, that when I have both the CSI and the Thermal Camera connected, there are 3 video devices: /dev/video0, video1 and video2, and when I unplug the Thermal Camera, only /dev/video2 stays.
Does anyone have experience with this or any other thermal camera and have a working gstreamer line to share?
