advance users, my question is:  
camera class often used on webcam monitor, if I want buffer the stream camera data. for example 3 second, is that possible? how to transform the data to video class?  
And is any idea for trigger the bufferd video data to playback last 3 second.  
I’m a beginner, any idea would help me a lot, thanks.
