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。
