Abstract: Embodiments of the invention provide techniques for encoding chunks of a video file in parallel. Embodiments may divide a source video file into a plurality of chunks, and may encode each chunk at a rate based upon complexity data associated with the chunk. The encoded chunks may then be reassembled to produce an encoded video file.

Abstract: Techniques are disclosed for a client device to stream a user-selected media file from a content server. The client device may create a playlist of dynamic virtual chunks to represent a single media stream file on a streaming media server. The playlist itself may be generated from an index in the header of a given stream defining what chunks, or segments of multiplexed audiovisual content, are present within that stream. The playlist of dynamic virtual chunks provides the playback engine on the client device with a list of individual files that may be requested from the streaming server independently of one another, despite the stream being stored on the server as a single media stream file.

Abstract translation: 公开了用于客户端设备从内容服务器流式传输用户选择的媒体文件的技术。 客户端设备可以创建动态虚拟块的播放列表，以在流媒体服务器上表示单个媒体流文件。 播放列表本身可以从给定流的标题中的索引生成，从而定义在该流内存在哪些块或多路复用的视听内容。 动态虚拟块的播放列表在客户端设备上提供可以从流传输服务器彼此独立地请求的单独文件的列表，尽管流作为单个媒体流文件存储在服务器上。
