LibWebRTCCodecs's createRemoteEncoder runs on a dedicated WorkQueue and is a WorkQueueMessageReceiver allowing it to send and receive IPC messages off the main thread. However, its use of sendWithAsyncReply means that all replies first transit through the main thread, which is a performance bottleneck Following bug 270118, we can instead use sendWithAsyncReplyOnDispatcher which allows to avoid the unnecessary re-dispatch.
