VideoPlayer

Decodes a video file or URL and exposes the current frame as a Texture.

var player = new VideoPlayer();
player.OnLoaded += () => Log.Info( $"Loaded {player.Width}x{player.Height}" );
player.Play( FileSystem.Mounted, "videos/intro.webm" );

Streaming over HTTP/HTTPS is also supported:

player.Play( "https://example.com/stream.webm" );

VideoPlayer.Texture updates each frame and can be used anywhere a Texture is accepted.

panel.Style.SetBackgroundImage( player.Texture );
material.Set( "Texture", player.Texture );

Audio settings live on the Audio accessor:

player.Audio.Volume = 0.5f;
player.Audio.Position = WorldPosition;
player.Audio.TargetMixer = Mixer.FindMixerByName( "Music" );

VideoWriter

Encodes a sequence of RGBA frames into a video file. Used internally by the screen recorder.

WebM supports transparency. The EncodingPreset on VideoWriter.Config controls speed vs quality: Fast for real-time recording, Balanced for general use, Quality for offline export.

var writer = new VideoWriter( "recordings/output.mp4", new VideoWriter.Config
{
    Width = 1920,
    Height = 1080,
    FrameRate = 60,
    Bitrate = 14,
    Codec = VideoWriter.Codec.AV1,
    Container = VideoWriter.Container.MP4,
    Preset = VideoWriter.EncodingPreset.Fast,
    AudioCodec = VideoWriter.AudioCodec.Opus,
} );

writer.AddFrame( rgbaBytes );

await writer.FinishAsync();
