The sample pipeline

FileSourceBlock → AACEncoderBlock → MP4SinkBlock

Sample code

var pipeline = new MediaBlocksPipeline(false);

var fileSource = new FileSourceBlock();
fileSource.Filename = "test.mp3";

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();
