AV1 encoder

AV1 (AOMedia Video 1): Developed by the Alliance for Open Media, AV1 is an open, royalty-free video coding format designed for video transmissions over the Internet. It is known for its high compression efficiency and better quality at lower bit rates compared to its predecessors, making it well-suited for high-resolution video streaming applications.

Use classes that implement the IAV1EncoderSettings interface to set the parameters.

The sample pipeline

Sample code

var pipeline = new MediaBlocksPipeline(false);

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

var videoEncoderBlock = new AV1EncoderBlock(new QSVAV1EncoderSettings());
pipeline.Connect(fileSource.VideoOutput, videoEncoderBlock.Input);

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

await pipeline.StartAsync();
