AVI files writing using Video for Windows interface.

The class allows to write AVI files using Video for Windows API.

Sample usage:

 // instantiate AVI writer, use WMV3 codec AVIWriter writer = new AVIWriter( "wmv3" ); // create new AVI file and open it writer.Open( "test.avi", 320, 240 ); // create frame image Bitmap image = new Bitmap( 320, 240 ); for ( int i = 0; i < 240; i++ ) { // update image image.SetPixel( i, i, Color.Red ); // add the image as a new frame of video file writer.AddFrame( image ); } writer.Close( );
