# Sample code

var pipeline = new MediaBlocksPipeline();

var filename = "test.mp4";
var fileSource = new UniversalSourceBlock(await UniversalSourceSettings.CreateAsync(new Uri(filename)));

var gaussianBlur = new GaussianBlurBlock();
pipeline.Connect(fileSource.VideoOutput, gaussianBlur.Input);

var videoRenderer = new VideoRendererBlock(pipeline, VideoView1);
pipeline.Connect(gaussianBlur.Output, videoRenderer.Input);            

await pipeline.StartAsync();
