/**
 * Internal remote interface for IMS's video call provider.
 *
 * At least initially, this aidl mirrors telecomm's {@link IVideoCallProvider}. We created a
 * separate aidl interface even though the methods and parameters are same because the
 * {@link IVideoCallProvider} was specifically created as a binder for inter-process communication
 * between Telecomm and Telephony.
 *
 * We don't want to use the same aidl in other places for communication, namely communication
 * between Telephony and the IMS Service, even if that communication may be for similar methods.
 * This decouples the communication among these processes. Similarly, third parties implementing a
 * video call provider will not have the benefit of accessing the internal
 * {@link IVideoCallProvider} aidl for interprocess communication.
