Show or hide a scene item within a scene. Get sceneId and sceneItemId from streamlabs_get_active_scene.

Permanently delete a source (removes it from every scene it appears in).

List the source types Streamlabs Desktop can create on this system (useful before calling streamlabs_create_source).

Get the current settings/properties for a source (e.g. the URL of a browser source, or the file path of a media source).

Update settings/properties for a source, e.g. { url: 'https://...' } for a browser_source, or { text: '...' } for text_gdiplus.

Rename a source (this renames the underlying source everywhere it's used, not just one scene item).

Duplicate a source, creating a new independent copy.
