# Third-party casting support

Provide custom playback controls for third-party casting services and other media sources.

## Overview

Overview Use the AVInterfaceControllable protocol suite to build custom transport controls that work with third-party casting services. The AVInterfaceControllable composite protocol combines playback, time, media selection, volume, and metadata capabilities into a single interface.
