The sample pipeline

Sample code

var pipeline = new MediaBlocksPipeline();

var filename = "test.mp3";
var fileSource = new UniversalSourceBlock(await UniversalSourceSettings.CreateAsync(new Uri(filename)));

var opusEncoderBlock = new OPUSEncoderBlock(new OPUSEncoderSettings());
pipeline.Connect(fileSource.AudioOutput, opusEncoderBlock.Input);

var oggSinkBlock = new OGGSinkBlock(new OGGSinkSettings(@"output.ogg"));
pipeline.Connect(opusEncoderBlock.Output, oggSinkBlock.CreateNewInput(MediaBlockPadMediaType.Audio));

await pipeline.StartAsync();
