     # Build the PeerConnectionFactory without audio/video support.
     # This target depends on the objc_peeerconnectionfactory_base which still
     # includes some audio/video related objects such as RTCAudioSource because
     # these objects are just thin wrappers of native C++ interfaces required
     # when implementing webrtc::PeerConnectionFactoryInterface and
     # webrtc::PeerConnectionInterface.
     # The applications which only use WebRTC DataChannel can depend on this
