I purchased a Topdon Thermal Camera, https://www.amazon.com/dp/B0B7LMB22Q. I'm trying to open the device on Fedora 39, x86_64, with the KDE spin.
I'm having trouble finding a KDE app to open the camera on F39. I've tried Dragon (video), Kamoso (camera) and Kamera (camera) apps. None of them seem to recognize the camera, and none of them open it.
Here is what dmesg has to say about the camera:
[153944.011515] usb 3-2.4: new high-speed USB device number 6 using xhci_hcd [153944.307093] usb 3-2.4: New USB device found, idVendor=0bda, idProduct=5830,bcdDevice=11.01 [153944.307107] usb 3-2.4: New USB device strings: Mfr=3, Product=1, SerialNumber=2 [153944.307111] usb 3-2.4: Product: USB Camera [153944.307113] usb 3-2.4: Manufacturer: Generic [153944.307116] usb 3-2.4: SerialNumber: 200901010001 [153944.326921] usb 3-2.4: Found UVC 1.00 device USB Camera (0bda:5830)
The USB Camera (0bda:5830) is known to Linux, see https://linux-hardware.org/?id=usb:0bda-5830.
And I may be doing something dumb, like not configuring one of the apps correctly. (I am used to using Cheese to open cameras like this, but I am not on Ubuntu).
What KDE software can I use to view the images from the Topdon?
I've made a little more headway. ffplay can open the device and stream the images. The command is:
$ ffplay /dev/video4 ... Input #0, video4linux2,v4l2, from '/dev/video4':B sq= 0B f=0/0 Duration: N/A, start: 160683.453275, bitrate: 19660 kb/s Stream #0:0: Video: rawvideo (YUY2 / 0x32595559), yuyv422, 256x192, 19660 kb/s, 25 fps, 25 tbr, 1000k tbn 161002.00 M-V: -0.040 fd= 2 aq= 0KB vq= 0KB sq= 0B f=0/0
In the last line, the [161002.00] is a counter that counts up by hundreds of a second. The other values stay contstant
