/**
 * \class FrameSink
 * \brief Abstract class to model a consumer of frames
 *
 * The FrameSink class models the consumer that processes frames after a request
 * completes. It receives requests through processRequest(), and processes them
 * synchronously or asynchronously. This allows frame sinks to hold onto frames
 * for an extended period of time, for instance to display them until a new
 * frame arrives.
 *
 * A frame sink processes whole requests, and is solely responsible for deciding
 * how to handle different frame buffers in case multiple streams are captured.
