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.
