The sample pipeline

UniversalSourceBlock → TeeBlock ... TeeBlock.Output1 → VideoRendererBlock TeeBlock.Output2 → H264EncoderBlock → MP4SinkBlock

Sample code

var pipeline = new MediaBlocksPipeline(false);

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

var videoTee = new TeeBlock(2);
var h264Encoder = new H264EncoderBlock(new MFH264EncoderSettings());
var mp4Muxer = new MP4SinkBlock(new MP4SinkSettings(@"output.mp4"));
var videoRenderer = new VideoRendererBlock(pipeline, VideoView1);

pipeline.Connect(fileSource.VideoOutput, videoTee.Input);
pipeline.Connect(videoTee.Outputs[0], videoRenderer.Input);
pipeline.Connect(videoTee.Outputs[1], h264Encoder.Input);
pipeline.Connect(h264Encoder.Output, mp4Muxer.CreateNewInput(MediaBlockPadMediaType.Video));

await pipeline.StartAsync();
