 * QTMSClientSink class

 *

 * This class provides QTMS client sink interface. It serves as a data sink

 * to the QTMS, which supplies the client with buffers recorded by the a/v

 * recording device. The constant flow of data between the a/v recorder

 * device and the client is accomplished by sending BufferProcessed() events

 * in response to TMSClientSinkObserver::ProcessBuffer sink observer callbacks.

 * This indicates to the QTMS that the supplied buffer has been consumed by the

 * client and it is ready to receive more recorded data.
