摘要： The disclosed embodiments provide a system which implements a notification barrier. During operation, the system receives a call to the notification barrier installed on a sender object, wherein the call originates from a receiver object which receives notifications posted by the sender object. In response to the call, the system acquires a notification lock, wherein the notification lock is held whenever the sender is posting a notification. The system then releases the notification lock, wherein releasing the lock indicates to the receiver object that the sender object has no pending posted notifications.

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. GOPs extend in coding order from a first key frame to a terminal frame that precedes another key frame in coding order. 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. All selected frames are decoded but only those marked for display are rendered at a display device. 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. Via these control parameters, operation of the method may be tuned to local decoding environments for which processing resources and decoded picture buffer sizes may be unknown.

摘要： A sequence of video images can be represented using multiple related timelines by generating a first timeline identifying a decode order associated with a sequence of video images and a second timeline identifying a display order associated with the sequence of video images, wherein the sequence of video images is comprised of one or more samples. The first and second timelines can be correlated based on an offset, which represents a time period by which decoding precedes display. The sequence of video images can then be played in accordance with the correlated first and second timelines. Additionally, the decode order in the first timeline can differ from the display order in the second timeline. A revised offset between the first and second timelines can be determined after the sequence of video images has been edited and the first and second timelines can be correlated based on the revised offset.
摘要翻译： 可以通过生成标识与视频图像序列相关联的解码顺序的第一时间线和标识与视频图像序列相关联的显示顺序的第二时间线，使用多个相关时间线来表示视频图像序列，其中视频图像序列 由一个或多个样品组成。 第一和第二时间线可以基于偏移来相关，该偏移表示解码在显示之前的时间段。 然后可以根据相关的第一和第二时间线来播放视频图像的序列。 此外，第一时间线中的解码顺序可以不同于第二时间线中的显示顺序。 可以在编辑视频图像的序列之后确定第一和第二时间线之间的修正的偏移量，并且可以基于经修改的偏移来相关联的第一和第二时间线。

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： In a device that can execute multiple media applications, but only one at a time, a media server coordinates among applications, but neither the media server nor the individual applications maintain rules regarding all of the different applications. Each connection used by an application is assigned a priority and communicates that priority to the media server when the connection is established. When an application requests to begin playback, the request is granted if no other application is playing, or if another application is playing on a connection having a priority at most equal to that of the connection used by the requesting application, but is denied if the connection already in use has a higher priority. Resumption of an application that was interrupted by another application on a connection with higher priority is determined by the interrupted application after the interruption ends, based on information communicated by the media server.

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.
