摘要： A system for camera device command and control detects a camera device connected to the system and accesses a set of interfaces defined by a standardized driver. The set of interfaces are a common set of interfaces associated with a device object and the device object is compatible with camera devices from different camera device manufacturers. The system queries the detected camera device for descriptors defining capabilities of the camera device using a packetized command generated based at least on the accessed set of interfaces and provides, based on the descriptors, one or more interfaces of the accessed set of interfaces to one or more applications to make the camera device available to the one or more applications, thereby simplifying connection of camera devices from different manufacturers and improving the user experience. The system then allows the camera device to be controlled.

摘要： A method is configured to increase efficiency of buffer usage within a pipeline of a computing device. The method includes creation of a buffer (120) in memory (110) of the computing device and caching of a memory descriptor list (208) by the computing device that describes the buffer in a buffer information cache (122) and has associated therewith a handle (210) that acts as a lookup to the memory descriptor list. The method also includes passing the handle through the pipeline (216) of the computing device for processing of data within the buffer by one or more stages (218,220) of the pipeline such that access to the data is obtained by the one or more stages by using the handle as the lookup as part of a call to obtain the memory descriptor list for the buffer from the buffer information cache.

摘要： The methods described herein are configured to correlate frames of a video stream to a system clock. A correlator application receives a frame of a video stream from a capture device via a bus interface, the frame including start frame and end frame timestamps based on a device clock of the capture device. A second start frame timestamp and second end frame timestamp are predicted based on previously received frames and a system clock. A skew value of the frame is calculated based on differences between the start frame timestamps and the end frame timestamps. Upon the calculated skew value exceeding a skew threshold, the frame is corrected to correlate to the predicted start frame and end frame timestamps. The corrected frame is then provided for display. Correcting timestamps of video stream frames in the described manner reduces jitter and enables accurate synchronization of multiple video streams.

摘要： Techniques for arbitrating control access to a shared resource among multiple client applications concurrently consuming a shared data stream associated with the shared resource are described. A server component instantiates a shared resource component representing the shared resource and associated shared data stream. The server component publishes a shared resource interface that provides central interface for the multiple client applications to access the shared resource and associated shared data stream. Each client application may access the shared resource in either control mode or shared mode to consume the shared data stream. In control mode, the client application has read-write access to control parameters representing a configuration of the shared resource that are usable to modify aspects of the shared data stream. In shared mode, the client application has read-only access to the control parameters.

摘要： User mode driver extension techniques are described. In one or more implementations, a computing device implements techniques that promote stability of execution of drivers performed by a computing device including stream preprocessing. The computing device includes a processing system to execute an operating system using a kernel mode and a user mode and memory configured to maintain instructions stored thereon that are executable by the processing system. The instructions include the operating system and a device driver and a user mode driver extension that correspond to a camera to support a communicative coupling between the camera and the operating system. The device driver is executable within the kernel mode and the user mode driver extension executable within the user mode. The user mode driver extension is configured to preprocess streams originated by the camera before processing by a camera pipeline of the operating system.
