c ++ OpenCV捕获easycap usb cam

Question

I am trying to get video stream from analog camera connected to usb easycap - in OpenCV C++.

using MATLAB, I can get stream the same approach like for laptop webcam (with changing the index from 1 to 2).

with OpenCV, I can get stream from laptop webcam with index 0. but when I am trying to get with the camera connected to the easycap (using index 1) , the laptop crashes and get blue screen.

Anyone have done this before?

Thanks

Answer 1

I work on the same device and I also have some BSOD with it.

Do you plug it with the USB extension provided ? If yes, try don't use it.

If your problem is still hapening, it's probably because like me, you use a low quality chinese fake EasyCap. I bought a real one and I haven't problems anymore

If you want to keep your device, you can use it with VideoCapture in python, it works very well and there is no more BSOD

Answer 2

Try using Linux. I tested my code with a fake EasyCAP in windows and I got many BSOD then I built and executed the same code in Linux and it worked. Linux is driver friendly.
