Description
============
Video source filter that produces an image of a bouncing ball.
This sample illustrates format negotiation and the use of the
source filter base classes CSource and CSourceStream.

============
The code in Fball.h and Fball.cpp manages the filter interfaces.
Those two files contain approximately the minimum code required
for a source filter. The Ball.h and Ball.cpp files contain the
code that bounces the ball.
This filter has a single output pin, which provides a video stream
that shows a ball bouncing around in the frame. The Ball filter
also accepts quality management requests from the downstream filter,
which illustrates a simple quality management strategy. This filter
implements the IQualityControl interface for that purpose.
The color of the ball corresponds to the current display bit depth:
8 bit - red balls
16 bit - blue
24 bit - green
32 bit - yellow
