Still from a webcam

Whats the best way to capture a still from a webcam for use in other ops. After button press still from video is transferred to new Top. Any ideas ?

Hey Ian, one way is to connect a Null TOP to your Video Device In TOP, and lock it with this python command:

op('null1').lock=True

You can unlock it with this command

op('null1').lock=False

Another way is to connect a Cache TOP to your Video Device In TOP, set its cache size parameter to 1, and its Active parameter to off. Now place a Cache Select TOP, and set it to look at your Cache TOP.
Now, everytime you pulse the Active parameter on your Cache TOP, you have a new still in your Cache Select TOP

aaa thx …then i was walking the right path :slight_smile:
