H264 encoder

The H264 encoder block is used for encoding files in MP4, MKV, and some other formats, as well as for network streaming using RTSP and HLS.

Use classes that implement the IH264EncoderSettings interface to set the parameters.

The sample pipeline

Sample code

var pipeline = new MediaBlocksPipeline();

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

var h264EncoderBlock = new H264EncoderBlock(new NVENCH264EncoderSettings());
pipeline.Connect(fileSource.VideoOutput, h264EncoderBlock.Input);

var mp4SinkBlock = new MP4SinkBlock(new MP4SinkSettings(@"output.mp4"));
pipeline.Connect(h264EncoderBlock.Output, mp4SinkBlock.CreateNewInput(MediaBlockPadMediaType.Video));

await pipeline.StartAsync();
