Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0029] Embodiment of the video stream playing method based on MPEG2

[0030] figure 1 An embodiment of the MPEG2-based video stream playing method of the present invention is shown. See figure 1 , the following is a detailed description of each step of the video stream playing method of this embodiment.

[0031] Step S10: Import video stream files.

[0032] Step S11: Analyze the video stream file.

[0033] In the process of analyzing the video stream file, the PSI (Program Specific Information, program specific information) information in the video stream file is firstly analyzed to obtain the information carried by the video stream and the audio stream. Then analyze the information of the video data in the video stream file, obtain the information of all video frames, and generate a video stream index (index) file.

[0034] According to the MPEG2...

Abstract

The invention discloses a video stream playing method and a device based on MPEG2, which can play video streams at different velocities under the condition of normal network band width. The invention has the technical scheme that the playing method comprises the following steps: (1) loading in a video stream file, analyzing the video stream file, and generating a video stream index file; and (2) inputting playing parameters, extracting video frames in the video streams according to the playing parameters, and playing the video stream frames based on the band width.

Description

technical field [0001] The invention relates to a video broadcasting processing technology, in particular to a video frame playing method in an MPEG2-based video processing broadcasting system. Background technique [0002] In the existing video processing and broadcasting system, a single broadcasting mode is used to broadcast video streams, and different corresponding broadcasting modes are used for different video files. [0003] This existing video processing and broadcasting system has the following disadvantages: (1) the broadcasting mode is inflexible; (2) a video needs to store a large amount of files; (3) the system consumes too many resources. Contents of the invention [0004] The purpose of the present invention is to solve the above problems, providing a method for playing video streams based on MPEG2, which can play video streams of different rates under the condition of normal network bandwidth. [0005] Another object of the present invention is to provide...
