C# Saving video stream as image files

Question

Is it possible to save out a video stream as image files using c# ?

I am able to save out one files easily, but can't keep up with the stream. I'm wondering if I can cache the bitmaps somehow before writing to disk to improve performance or something similar

You need to use some 3rd part tools such as AForge. The example ectracted from AForge documentation

Sample code

// create instance of video reader
VideoFileReader reader = new VideoFileReader( );
// open video file
reader.Open( "test.avi" );
// read 100 video frames out of it
for ( int i = 0; i < 100; i++ )
 {
   Bitmap videoFrame = reader.ReadVideoFrame( );

    videoFrame.Save(i + ".bmp")

// dispose the frame when it is no longer required
videoFrame.Dispose( );
 }
 reader.Close( );
