The sample pipeline

Sample code

var pipeline = new MediaBlocksPipeline();

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

var aacEncoderBlock = new AACEncoderBlock(new MFAACEncoderSettings() { Bitrate = 192 });

pipeline.Connect(fileSource.AudioOutput, aacEncoderBlock.Input);

var m4aSinkBlock = new MP4SinkBlock(new MP4SinkSettings(@"output.m4a"));
pipeline.Connect(aacEncoderBlock.Output, m4aSinkBlock.CreateNewInput(MediaBlockPadMediaType.Audio));

await pipeline.StartAsync();
