    I bought a cheap USB Endoscope, and I'd like to use the Pandora as a display for it, but I have been unable to find an application that will do that. Something like "Cheese" would be sufficient, but I have not found that for the Pandora.
    Can someone suggest something equivalent?
    Thanks.

    If you just want to use it as a monitor for it, and not take video, I uploaded a PND that's just called Camera.

    Both VLC and SMPlayer2 seem to want video files, and don't seem to know what to do with a camera.
    "Camera" just does not run on my pandora. It fails silently. no window ever opens.

    Both should have a method of using a USB camera as a capture device.

    @DAP I'll try to explain how I use it.

    First of all, you need a camera that does USB2 (or can go down from USB3 to USB2, or you have a real USB2 hub connector that allows 1.1 and transmits it as USB2).

    Step 2 is to connect everything to your usb port. ONLY THEN enable USB.

    Now drop down to the commandline and type "dmesg". Check that you have something successful, like "input: USB2.0 camera as /devices/..." and "usbcore: registered new interface..."

    If so, open up VLC (I use the old one) and CONTROL+C this will open up the capture device screen, and the PLAY button is just out of screen. So while pressing shift, with the stylus do a flick of the wrist like you do when you cast "Windgardium Leviosa" (drag the screen up to reveal the bottom).
    Do not input anything, just go with the defaults and press "play".

    Crud. Do you have the Community Codec Pack installed? You need mplayer for the PND to work. It's just a shell script so it should still work, hopefully.

    Yes, the Community Codec Pack is installed.

    When I do this, I get the following error message:
    Your input cant be opened:
    VLC is unable to open the MRL 'v4l2://'. Check the log for details.

    The camera is a USB High Speed device, it has a USB type C connector, even though it is no a super speed device. I am using it with a USB-C to USB A adapter.
    It shows up as "/dev/v4l/by-id/usb-lihappe8_Corp._USB_2.0_Camera-video-index0".
    This is the camera:

    Ok. Strange. I have a digital microscope and a logitec webcam and both do not require extra stuff... so I suspect we are missing some firmware. What does the dmesg say and su to root and "lsmod"

    I just tried a webcam with the Camera PND, and it didn't work. Apparently /dev/video0 is missing. I suspect the case is the same for DAP, which would explain why it's not working. It's possible firmware is missing, yeah. Although, the webcam is logitech, it's very old so maybe it doesn't support UVC.

    Probable typeoes here as I am attempting to manually type in these responses. (I'm posting on my desktop, the Pandora is not really convenient for web browsing unless a desktop can't be had)

    Don't know if we have mjpeg-streamer but searching on web i found this page https://github.com/foosel/OctoPrint/wiki/Webcams-known-to-work
    it says:

    I already know this camera works with linux. It works on my desktop with Cheese, hence my request for something similar to Cheese for the Pandora. On my desktop, I only need to plug in the camera, run Cheese (or one of the other web cam apps available for linux mint, but not available for the pandora), select that particular USB web cam from a drop down menu, and I am displaying a picture.
    But I can't really haul my desktop where an endoscope would prove useful (crawl space under my house etc), hence the need for some application on the Pandora.

    BTW, "using the TV address" What TV address? what is the syntax? Where do you put this in the VLC application?

    @DAP You are missing the last step?
    [] usbcore: registered new interface driver uvcvideo

    You said it worked on your Linux system. Reboot that system, do a "lsmod > /tmp/before.txt", plug it in and do a "lsmod > /tmp/after.txt" diff the files, see if you see a string that is similar in name to one of the /lib/firmware/*.fw files, copy that one over to the Pandora if not available (preserve subdirectories).

    In /lib/udev/* are the binaries that check devices and /lib/udev/rules.d/* has the rules that make the /dev/* files (/dev/v4l/by* in our case) pointing to the device.
    you can manually modify these rules (to hardcoded add something like ATTR{idVendor}=="038f", ATTR{idProduct}=="6001", ..... /dev/v4l/{...}/...) but that is not necessary, as it shows up as "/dev/v4l/by-id/usb-lihappe8_Corp._USB_2.0_Camera-video-index0".


    Firmware (note that the DVB*.fw are TV dongles):
    https://github.com/LibreELEC/dvb-firmware/tree/master/firmware


    Using the TV:// see: https://github.com/TheImagingSource/tiscamera/wiki/Linux-Support-for-USB-Cameras

    lsmod diff is not very enlightening
    Code:
    $ diff Controllsmod.txt testlsmod.txt
    90c90
    < usb_storage            69632  2 uas
    ---
    > usb_storage            69632  1 uas
    
    I did verify that the camera does still work with Cheese.

    I tried vlc, but vlc chose to use the other web cam I have installed, and I did not see how to tell vlc to use this one. (it is inconvenient to disconnect the other camera)

    lsusb has lots to say about this camera:
