The sample pipeline
Sample code
var pipeline = new MediaBlocksPipeline();
var filename = "test.mp3";
var fileSource = new UniversalSourceBlock(await UniversalSourceSettings.CreateAsync(new Uri(filename)));
var speexEncoderBlock = new SpeexEncoderBlock(new SpeexEncoderSettings());
pipeline.Connect(fileSource.AudioOutput, speexEncoderBlock.Input);
var oggSinkBlock = new OGGSinkBlock(new OGGSinkSettings(@"output.ogg"));
pipeline.Connect(speexEncoderBlock.Output, oggSinkBlock.CreateNewInput(MediaBlockPadMediaType.Audio));
await pipeline.StartAsync();
