Hi all,

After doing many rounds of googling, i have no choice but to post my question. I trying to do a videocapture with opencv 3.1.0, windows 7 and external logictech webcam C110. But i have encountered a black screen. i debugged and noted that the videocapture returns an array of 0. i indicated 0 for the camera id.

Anyone can advice? thank you

thanks for replying. i had: 1) checked with VLC, the VLC shows the camera is working. 2) i tried the camera with another of my notebook and it is working with the code. 3) i tried the camera again on my current machine and it does not work. i noted that that the code need to execute many times until suddenly the camera is able to show up in the frame. but then if i restart the code, it does not work, i have to restart it many times until the video is show again...i still don't know why it does so
