摘要： A battery operated device, having a display with two or more available refresh rates, has its refresh rate selected so as to match the video frame rate of video data played back on the display. This selection is made by coordinating the resources in the device that are used to process the video from its reception through to its display.

摘要： A video bit stream with pictures comprising inter-coded content can be decoded upon receiving a channel start or file seek instruction. Pictures for beginning decoding and display of the bit stream can be selected based at least in part on one or more tuning parameters that set a preference between a latency of beginning to display video and possible defects in the displayed video. In some embodiments, to implement decoding upon a channel start or file seek, one or more types of data are generated for one or more pictures. For example, picture order counts are generated for pictures after a channel start or file seek operation. As another example, a decoder generates a frame number value that triggers re-initialization of a reference picture buffer before decoding after a channel start or file seek operation.

摘要： Video image stabilization provides better performance on a generic platform for computing devices by evaluating available multimedia digital signal processing components, and selecting the available components to utilize according to a hierarchy structure for video stabilization performance for processing parts of the video stabilization. The video stabilization has improved motion vector estimation that employs refinement motion vector searching according to a pyramid block structure relationship starting from a downsampled resolution version of the video frames. The video stabilization also improves global motion transform estimation by performing a random sample consensus approach for processing the local motion vectors, and selection criteria for motion vector reliability. The video stabilization achieves the removal of hand shakiness smoothly by real-time one-pass or off-line two-pass temporal smoothing with error detection and correction.

摘要： A video encoding acceleration service to increase one or more of the speed and quality of video encoding is described. The service acts as an intermediary between an arbitrary video encoder computer program application and arbitrary video acceleration hardware. The service receives one or more queries from the video encoder to identify implementation specifics of the video acceleration hardware. The service interfaces with the video acceleration hardware to obtain the implementation specifics. The service communicates the implementation specifics to the video encoder. The implementation specifics enable the video encoder to: (a) determine whether one or more of speed and quality of software encoding operations associated with the video encoder can be increased with implementation of a pipeline of one or more supported encoding pipeline configurations and capabilities, and (b) implement the pipeline by interfacing with the service.

摘要： A media processing comparison system (“MPCS”) and techniques facilitate concurrent, subjective quality comparisons between media presentations produced by different instances of media processing components performing the same functions (for example, instances of media processing components in the form of hardware, software, and/or firmware, such as parsers, codecs, decryptors, and/or demultiplexers, supplied by the same or different entities) in a particular media content player. The MPCS receives an ordered stream of encoded media samples from a media source, and decodes a particular encoded media sample using two or more different instances of media processing components. A single renderer renders and/or coordinates the synchronous presentation of decoded media samples from each instance of media processing component(s) as separate media presentations. The media presentations may be subjectively compared and/or selected for storage by a user in a sample-by-sample manner.

摘要： Reference pictures can be created to assist with video decoding. For example, a method for decoding video can comprise receiving an encoded video bit stream, determining that a reference picture is needed, and creating and inserting the reference picture into the encoded video bit stream. A method for decoding video can also comprise receiving an encoded video bit stream, performing bit stream parsing, determining that a reference picture is needed, selecting a representation level for the reference picture, and conveying data for the selected reference picture to a hardware accelerated graphics processing unit. Various video operations, such as creating reference pictures and related information, can be performed by central processing units, while other video decoding operations can be performed by graphics processing units.

摘要： Accelerating video data decoding is described. In one aspect, hardware accelerated video decoding operations are configured to decode source video data in a first encoded data format. During video data processing operations, the source video data is evaluated to detect any change in the encoding format. Responsive to detecting a change in the source video data encoding, wherein the changed encoding is at least partially incompatible with the first encoded data format, the hardware accelerated video decoding operations are dynamically reconfigured. The reconfigured decoding operations decode the source video data content based on the changed encoded data format.
