2019-11-17 11:53:25 -0600 | marked best answer | Check camera activity Hello How can I check a camera activity? I would like to know is camera on/off AND is any program currently use a camera? I tested the code from https://docs.opencv.org/3.0.0/d8/dfe/... I opened Skype -> Setting -> Camera Preview. Camera switched on. Then I executed the code. Only in "for" section after line "cap>>frame;" I understood than another program has already captured the camera. I found out that by check: If I close Skype and call from the code I turn camera on. (I see light on my device). Is it possible to check camera activity without starting "record video" ? I tried to compare different properties when camera on and off. But the results are the same. Is exists approach to check camera activity without "switch camera on" for a second? |
