摘要： In a method and system for offline content playback, a first plurality of portions of content streamed from a content sharing service for presentation by a media player is received. A request from a user to make the content available for offline playback is received, and in response to the request, a second plurality of portions of the content streamed from the content sharing service for presentation by the media player is stored. The first plurality of portions is requested and received from the content sharing service. The received first plurality of portions is stored, such that the first plurality of portions and the second plurality of portions are available for offline playback.

摘要： A streaming video playback system is provided to generate locally a manifest file associated with a streaming video for a media player of a client device. The locally generated manifest file helps reduce startup time for the media player and the manifest file is locally generated based on streaming metadata associated with the streaming video and the manifest files includes HTTP Live Streaming (HLS) based master playlists and media playlists. The locally generated manifest file also provides better adaptive bit rate control by enabling pre-fetching of video segments of a streaming video and caching during playback. The streaming video playback system reduces the size of media playlist transmitted to a content sharing service using index of the last video segment and makes it practical to have DVR-able live video streaming with a larger seek window.
摘要翻译： 提供流式视频播放系统，用于在本地生成与用于客户端设备的媒体播放器的流式视频相关联的清单文件。 本地生成的清单文件有助于减少媒体播放器的启动时间，并且基于与流式视频相关联的流式元数据本地生成清单文件，并且清单文件包括基于HTTP Live Streaming（HLS）的主播放列表和媒体播放列表。 本地生成的清单文件还通过在播放期间预取流式视频的视频片段和高速缓存来提供更好的自适应比特率控制。 流式视频播放系统使用最后一个视频片段的索引来减少发送到内容共享服务的媒体播放器的大小，并且使得具有更大的搜索窗口的具有DVR的实时视频流传输成为可行。

摘要： A media item is presented via a media player, the media player configured to receive the media item, the media item being associated with a format and including an audio component. Responsive to a change in a display mode associated with the media player, a second media player is identified that is configured to receive a corresponding media item, the corresponding media item being associated with a second format and including a second audio component that matches the audio component. A particular location is determined in the media item to cease presentation of the media item via the media player and a corresponding location in the corresponding media item to begin presentation of the corresponding media item using the second media player. Responsive to reaching the particular location, concurrently, presentation of the media item is ceased and presentation of the corresponding media item at the corresponding location is begun.
