HTI HT-203U Thermal Imager Raspberry Pi OS

[5B4APV]

Hello!

I am trying to view the UVC video stream of the HT-203U 256x192 USB C thermal camera on raspberry pi os but I haven't been able to.
I have tried through VLC, guvcview, cheese and ffmpeg

The thermal imager works fine as a webcam on Windows, but on Pi os it wont display anything and each software prints errors when trying to connect to it.

The format that works on windows is YUYV422 256x192

Any guidance on how to view live video from this device will be greatly appreciated.

Bellow are the outputs of 2 commands that show the details of the video stream the device outputs.


ffmpeg -f v4l2 -list_formats all -i /dev/video0:

I believe it's possibly a wrong driver selected for the device, but the resolutions seem correct.
