*Old usb-webcam not working*

Good afternoon,

(Medion) Tevion MD9388
(ik like 20 years old but should do the job?)

The camera does not output an image. It is shown up in lsusb and stuff but i do not know wether i can get it to work at all.

I tried using -y -u and change the framrate/resolution in the octopi.txt but it did not work. Then I used lsusb to see wether the camera is connected and it is.

lsusb

I also used 4l2-ctl --list-formats-ext to see if I used the right settings.

The Pixel Format is kinda weird? Is it even possible?

The easy answer is that webcam is not supported.

The longer answer is it might work with a driver, but it will be hard to find one for Raspberry Pi.

The simple truth is video from a 20 year old webcam is going to look shitty and not worth the trouble.

If you just want a simple picture to have an eye on your printer you can buy this webcam

Trust SpotLight 

the picture is nothing special but you can see what you need.
it just costs a few euros/dollars/whatever on ebay or amazon

(yeah I know it's a mess :smiley: )

Thanks a lot for your answers.

Kind of what I expected so.i might look after the Logitech C270 or Something like this.

Best regards

Sorry if I misspeak, but isn't the whole point of UVC camera that no external driver is required?

Or is this specific to ov511? What is ov511 by the way?

Hello @aboode95 !

I'm afraid you are a bit late for this discussion.

4 years late yes xD I see that, though I hope to get some clarification on why this UVC camera cannot work? Considering that the camera works with apps such as "guvcview" and "xawtv" in linux. Since Raspberry OS is based on linux, shouldn't it work? I am just simply trying to understand and looking for some clarification :smile:

(Please forgive me if I misspoke here in anyway)

Edit: Oh and hello to you too @Ewald_Ikemann ! :))
