lass="hl com"> * \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. */ FrameSink::~FrameSink() { } int FrameSink::configure([[maybe_unused]] const libcamera::CameraConfiguration &config) { return 0; } void FrameSink::mapBuffer([[maybe_unused]] libcamera::FrameBuffer *buffer) { } int FrameSink::start() { return 0; } int FrameSink::stop() { return 0; } /** * \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 */
