Abstract
Systems and methods for nonlinear media playback using a linear media player are described. In one implementation, a video tree representing a branching video presentation is provided, and a dynamic playlist is provided to a linear video player. A controller component interacts with the linear video player through a standard interface of the linear video player. During playback of a video content segment in the dynamic playlist by the linear video player, an indication of a user interaction with the playing video content segment is received by the controller component and from the linear video player via the standard interface, and the dynamic playlist is modified based on video content segments in a branch of the video tree. In another implementation, an uncompressed media file is selected and combined with a preceding and/or following media file. The combined files are compressed and a portion of the compressed file corresponding to the original media file is extracted.
