Abstract

The invention discloses a method of playing a streaming media video file with a variable rate, which comprises two parts of video information editing and video playing. In a manual editing method, a speed multiplication label of the video is generated in advance and the speed multiplication label is provided in a certain format; and according to the speed multiplication label information, video data in a label description range are played according to a speed multiplication value set by the label, needed fast and slow video file playing is realized, and the user still can watch the video with a normal rate. Thus, according to the method of the invention, while variable-speed playing of the video is realized, the right of selection of audience is still kept.
