Specifies when cast devices discovery starts.

  • Discovery will start when the BitmovinCastManager.initializeCasting is called for the first time.

  • Discovery will start when the GCKUICastButton is tapped for the first time.

    Only use this option when you use a custom UI with a GCKUICastButton. Using this option with our Bitmovin Player UI will result in no cast button being visible.
