Play, pause, seek, and adjust audio or video, and react to transport controls. Use for "play some music", "pause", "skip ahead 30 seconds", "turn it up", or "play that video". Triggers: play, pause, resume, stop, skip, seek, rewind, volume, louder, quieter, next track, music, video.

Control Media Playback

Drive a media_player (and, for music, an optional music_visualizer) and handle its transport events.

Steps

  1. Resolve the source. A named track/video → resolve a source_url + media_type (audio|video). "Play music" with no title → a default playlist.
  2. Start with play_media. Spawns a media_player (state:"playing").
  3. For music, add ambience with show_music_visualizer (audio-reactive).
  4. Handle controls (client.interaction, §5.11) with holo.update:
    • play_pause → toggle state.
    • seek{position_ms} → set position_ms.
    • set_volume{volume} → set volume (0–1).
    • stop → state:"stopped" or holo.destroy.
  5. Map speech to actions: "turn it up" → volume += 0.1; "skip 30s" → position_ms += 30000.

Output

media_player (play_media, props per registry.json):

{ "widget_type": "media_player",
  "transform": { "anchor": "world", "billboard": true },
  "props": { "title": "Lo-fi Beats", "source_url": "https://cdn.jarvisvr.app/audio/lofi.mp3",
             "media_type": "audio", "state": "playing", "position_ms": 0,
             "duration_ms": 180000, "volume": 0.6, "loop": true },
  "interactions": ["tap","grab","resize","slider"] }

music_visualizer (show_music_visualizer):

{ "widget_type": "music_visualizer",
  "props": { "track": "Lo-fi Beats", "artist": "Chillhop", "style": "bars",
             "amplitude": [0.2,0.6,0.9,0.4,0.7], "color": "#7FE7FF", "playing": true } }

Edge cases

  • Source not found → say so; offer alternatives, don't fabricate a URL.
  • Nothing playing ("pause") → no-op with a gentle note.
  • Volume bounds → clamp to 0.0–1.0.
  • Video vs audio → video uses a larger world-anchored player; keep it out of the user's path (defer placement to stage-agent).
  • Ambient background loop (rain, café) → that's set-soundscape.
  • Generate cover art / imagery → create-image.
