Configure and start the http server, specifying a specific network interface, or 'any' for default.
To specify an interface, use either the DNS name or the IP of the NIC. ex: 10.68.212.33 or my-ioc-server-hostname Default port is 8080.

Configuration routine.
Called directly, or from the iocsh function, calls ffmpegStream constructor:
Constructor for ffmpegStream; Class representing an mjpg stream served up by ffmpegServer. ffmpegServerConfigure() must be called before creating any instances of this class. ffmpegStreamConfigure() should be used to create an instance in the iocsh. See ffmpegStream.template for more details of usage.
\param portName The name of the asyn port driver to be created. \param queueSize The number of NDArrays that the input queue for this plugin can hold when NDPluginDriverBlockingCallbacks=0. Larger queues can decrease the number of dropped arrays, at the expense of more NDArray buffers being allocated from the underlying driver's NDArrayPool. \param blockingCallbacks Initial setting for the NDPluginDriverBlockingCallbacks flag. 0=callbacks are queued and executed by the callback thread; 1 callbacks execute in the thread of the driver doing the callbacks. \param NDArrayPort Name of asyn port driver for initial source of NDArray callbacks. \param NDArrayAddr asyn port driver address for initial source of NDArray callbacks. \param maxBuffers The maximum number of NDArray buffers that the NDArrayPool for this driver is allowed to allocate. Set this to -1 to allow an unlimited number of buffers. \param maxMemory The maximum amount of memory that the NDArrayPool for this driver is allowed to allocate. Set this to -1 to allow an unlimited amount of memory. \param priority The thread priority for the asyn port driver thread if ASYN_CANBLOCK is set in asynFlags. \param stackSize The stack size for the asyn port driver thread if ASYN_CANBLOCK is set in asynFlags.
