I use win7 64bit, webcam capture complete dark, I follow troubleshoot, but it still dark. I see many people have the problem like me.
This is probably the known issue with certain web cameras.
See the following for reference…
The Prey team have tried many thing to fix this, and people are still looking for a solution, I'm sure any suggestions (or code examples) would be appreciated.
Please close this issue because it is effectively a duplicate of #166
