/*

|
|
CSGCamera provides a simple way to access the default sequence grabber component (say, an iSight or other DV camera). To use:
|
||
|
|
|
||
|
|
- Instantiate an CSGCamera instance (using the plain old -init method)
|
||
|
|
- Set the CSGCamera's delegate using -setDelegate:. The delegate is the object which will receive -camera:didReceiveFrame: messages.
|
||
|
|
- Call -startWithSize: on the CSGCamera instance with a decent size (like 512x384).
|
||
|
|
- Call -stop to stop recording.
|
