VideoPlayer
Decodes a video file or URL and exposes the current frame as a Texture.
| Codec | Containers | Notes |
|---|---|---|
| VP9 | .webm, .mp4 | |
| AV1 | .webm, .mp4 | Best compression and quality |
| WebP | .webp | Supports transparency |
| H.264 | .mp4 | Windows only via Media Foundation, not recommended |
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.
| Codec | Containers | Notes |
|---|---|---|
| VP9 | .webm, .mp4 | Best compatibility |
| AV1 | .webm, .mp4 | Best compression and quality |
| WebP | .webp | Animated WebP, supports transparency |
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.
VideoWriter is editor-only and is created through EditorUtility.CreateVideoWriter() (in the Editor namespace); its constructor is internal.
var writer = EditorUtility.CreateVideoWriter( "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();
