-/**
- * \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.

-/**
- * \fn FrameSink::processRequest()
- * \param[in] request The request
- *
- * This function is called to instruct the sink to process a request. The sink
- * may process the request synchronously or queue it for asynchronous
- * processing.
- *
- * When the request is processed synchronously, this function shall return true.
- * The \a request shall not be accessed by the FrameSink after the function
- * returns.
- *
- * When the request is processed asynchronously, the FrameSink temporarily takes
- * ownership of the \a request. The function shall return false, and the
- * FrameSink shall emit the requestProcessed signal when the request processing
- * completes. If the stop() function is called before the request processing
- * completes, it shall release the request synchronously.
- *
- * \return True if the request has been processed synchronously, false if
- * processing has been queued
