摘要： A system and methods provide handling of variable rate playback in a multimedia computer architecture. The systems and methods provide data structures and interfaces that enable a computer architecture and components therein with the ability to playback data at speeds faster and slower than real-time, to playback data in reverse, and to change the rate of playback at any point during playback. One embodiment is a method for providing low-latency, glitch-free changes in a multimedia architecture. Other embodiments are directed to defining multimedia component responsibilities for making rate changes, allowing rate changes to work with standard playback types, coder-decoders, and renderers. The methods include determining a minimum of the maximum reported playback rates and determining minimum and maximum playback rates in a set of modes including: reverse skip mode, reverse key frame mode, reverse full mode, forward full mode, forward key frame mode, and forward skip mode.

摘要： Methods, systems, and computer program products for arbitrarily indexing multimedia content. In accordance with example embodiments, a multimedia content stream that comprises one or more samples is received. At least one of the samples is passed to one or more multimedia filters for analysis based on criteria that define an index type for the multimedia filter. Once it is determined that the sample meets the criteria for an arbitrary filter and index type, an index entry that identifies both the sample and the index type of the arbitrary filter is created. The index entry is adapted in accordance with a common, extensible indexing scheme to coexist with other index entries of other or the same index type for the sample. The created index entry is stored for subsequent access.

摘要： This disclosure describes methods, systems, and programming interfaces for more efficiently processing media data in a media pipeline. In one embodiment, media flow in a media system is coordinated using a media foundation transform supported by a programming interface. The programming interface generates input and output events to the requisite media system thereby permitting the media foundation transform control over when input frames are requested and received and output frames are retrieved.

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： Methods, systems and architectures for processing renderable digital content are described. The various embodiments can protect against unauthorized access or duplication of unprotected content (i.e. decrypted content) once the content has reached a rendering device such as a user's computer. A flexible framework includes an architecture that allows for general media sources to provide virtually any type of multimedia content to any suitably configured rendering device. Content can be protected and rendered locally and/or across networks such as the Internet. The various embodiments can provide a standard platform that can that can be leveraged to protect content across a wide variety of rendering environments, content types, and DRM techniques.

摘要： Techniques and tools for representing pixel data in a video processing or capture system are described. Described techniques and tools provide efficient color representation for video processing and capture, and provide flexibility for representing colors using different bit precisions and memory layouts. Described techniques and tools include video formats that can be used, for example, in hardware or software for capture, processing, and display purposes. In one aspect, chroma and luma information for a pixel in a video image is represented in a 16-bit fixed-point block of data having an integer and fractional components. Data can be easily converted from one representation to another (e.g., between 16-bit and 10-bit representations). In other aspects, formats for representing 8-, 10- and 16-bit video image data (e.g., packed and hybrid planar formats), and codes for indicating the formats, are described.
