/// Configures single source property's visibility, possible modification callback and callback payload data, as well as whether the property should be enabled
/// - Parameters:
///   - property: The source property to change
///   - enable: Whether the source property should be enabled (user-changeable)
///   - visible: Whether the source property should be visible
///   - callback: Pointer to a function that will be called if this property has been modified or the properties are reloaded
///   - capture: Optional reference to ``OBSAVCapture`` instance

///   - settings: Pointer to settings associated with the source

/// * Resolutions
/// * Frame rates and frame rate ranges
/// * Color formats
/// * Color range
///
///  In CoreMediaIO color format, resolution and frame rate ranges are always coupled into a single format, while color range is always contained in the color format. The formats are thus compiled and de-duplicated to create a selection of all properties.

///   - settings: Pointer to settings associated with the source
/// - Returns: Always returns true
