    摘要： A video decoder includes a mode of operation for reverse playback that includes dividing a sequence of coded video data into groups of pictures (GOPs) and further subdividing the groups of pictures into a plurality of spans. Each span is processed in reverse coding order by decoding the first key frame and any reference frames that precede the currently processed span in coding order, selecting a plurality of frames from the currently processed span for decode and display and further selecting for decode but not display any reference frames from the currently processed span that were omitted by the first selection. The method accommodates control parameters that define the number of spans selected from each GOP and the number of frames selected from each span for decoded and display.

    摘要： Memory objects associated with a portion of a cache (e.g., data blocks of a media file) are assigned a value based on their importance to an application that is consuming memory objects. The values are used to assign the data blocks to purge groups. The purge groups are a labeling mechanism for determining a purge order. A memory object associated with a first data block assigned to a first purge group may be purged before a memory object associated with a second data block assigned to a second purge group. As new data blocks are received by the application (e.g., from disk or a network connection), the blocks are assigned a value and added to a purge group. In some cases, the data blocks arrive out of order (e.g., order of consumption). Memory objects can be reassigned to a different purge group when new data blocks are added or reclaimed.

    摘要翻译： 与高速缓存的一部分（例如，媒体文件的数据块）相关联的存储器对象被分配一个值，该值基于它们对正在消耗存储器对象的应用的重要性。 这些值用于将数据块分配给清除组。 清洗组是用于确定吹扫顺序的标签机制。 与分配给第一清除组的第一数据块相关联的存储对象可以在与分配给第二清除组的第二数据块相关联的存储器对象之前清除。 当应用程序接收到新的数据块（例如，从磁盘或网络连接）时，将为块分配一个值并将其添加到清除组。 在某些情况下，数据块无序到达（例如，消费顺序）。 当添加或回收新的数据块时，可以将内存对象重新分配给不同的清除组。

    摘要： A module may provide codec-independent services including determining frame display order, frame dependency sets, and queuing the dependency frames in advance so as to enable display of a video. The module enables a video to be played forwards or backwards at a variety of playback speeds from any position within the video. In one implementation, a device communicatively coupled to a plurality of decoders accesses a video that includes a plurality of frames. One or more of the frames are decodable by one or more of the communicatively coupled decoders. The device identifies a frame in the video that is to be displayed, and determines a plurality of dependency frames in the video upon which decoding of the frame to be displayed depends. The device provides an indication that one or more associated dependency frames are to be decoded.

    摘要： A sequence of video images represented using multiple related timelines can be searched by identifying a first point on a first timeline associated with the sequence of video images, wherein the sequence of video images is comprised of one or more samples, determining a search range on a second timeline associated with the sequence of video images based on a positive offset and a negative offset associated with the one or more samples, and searching the second timeline based on the determined search range for a second point that corresponds to the identified first point. A display offset can be associated with each of the samples comprising the sequence of video images, wherein one or more of the display offsets can comprise a negative value. Additionally, the search range can be based on a maximum positive display offset and maximum negative display offset associated with the one or more samples.
