                  int qual,
                  int fps)

Create JPEGCamera to grab images with the specified dimension, quality, and hardware framerate. Even if you intend to use a frame rate lower than 25 (TV-standard), you should normally use 25 anyway but simply reading the image less frequent. That is to avoid delays.

public JPEGEvent getNextFrame()
