AVI file video source.

The video source reads AVI files using Video for Windows.

Sample usage:

 // create AVI file video source AVIFileVideoSource source = new AVIFileVideoSource( "some file" ); // set event handlers source.NewFrame += new NewFrameEventHandler( video_NewFrame ); // start the video source source.Start( ); // ... // signal to stop source.SignalToStop( ); // New frame event handler, which is invoked on each new available video frame private void video_NewFrame( object sender, NewFrameEventArgs eventArgs ) { // get new frame Bitmap bitmap = eventArgs.Frame; // process the frame }

Méthodes publiques

Méthode	Description
AVIFileVideoSource ( ) : System	Initializes a new instance of the AVIFileVideoSource class.
AVIFileVideoSource ( string source ) : System	Initializes a new instance of the AVIFileVideoSource class.
SignalToStop ( ) : void	Signal video source to stop its work. Signals video source to stop its background thread, stop to provide new frames and free resources.
Start ( ) : void	Start video source. Starts video source and return execution to caller. Video source object creates background thread and notifies about new frames with the help of NewFrame event.
Stop ( ) : void	Stop video source. Stops video source aborting its thread. Since the method aborts background thread, its usage is highly not preferred and should be done only if there are no other options. The correct way of stopping camera is signaling it stop and then waiting for background thread's completion.
WaitForStop ( ) : void	Wait for video source has stopped. Waits for source stopping after it was signalled to stop using SignalToStop method.
