Can this be treated as a camera where I could use opencv features such as image/color tracking on a computer screen?

hi, i want to record my screen by always using fix duration of time . which is always 10 s because i want to record signature . at which line should i put the fix value ?

Thanks for sharing ur valuable knowledge! do you have any idea about re-opening the out.release().
for ex: I am interfacing 2switches to stop and to start record, once I pressed sw1 it should start recording and when I pressed sw2 it should stop recording(both are working fine). the problem is when I press sw1 again the start recording should run, but it is not recording. the reason is that while stop recording we closed out.release(). we have to re-initialize out.release() so how can i re-open out.release() function again to start recording.
please do help me I am a beginner to python struggling from last month.

your help will be greatly appreciated!

thank you
Ramesh

What should be the frames/sec value to match the clock duration? With 16 frames/sec i am getting recording of ~17 minutes but the actual clock duration is ~15 minutes.

cv2.error: OpenCV(4.2.0) error: (-2:Unspecified error) The function is not implemented. Rebuild the library with Windows, GTK+ 2.x or Cocoa support. If you are on Ubuntu or Debian, install libgtk2.0-dev and pkg-config, then re-run cmake or configure script in function 'cvShowImage' I got that error

Seems like a easy way to capture the screen but how could I make a program that sees data from the code and runs another set of lines to move and click?

I have a problem with the mirrored window running on an infinite loop how do i prevent this

[isademigod]

How would you use this for object detection? When you try and import it as

ret, frame = video.open()

it gives an error saying that ndarray can't be used for video
