Embodiment Construction

[0027] The specific implementations of the video extension code setting and video playing method and system of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0028] refer to figure 1 , figure 1 Shown is the flow chart of the video extension code setting method of an embodiment, including the following steps:

[0029] S10, reading extension information from a preset video file, and setting an extension code according to the extension information;

[0030] The above-mentioned video file is a file for storing content such as relevant playback material and characteristic information of a corresponding player. The playback material in the video file is usually set with an identifier such as a material name or a material keyword that can uniquely characterize the playback material. Through the above-mentioned identifier, it can be judged whether the corresponding playback material can be played on common players (various p...

Abstract

The invention relates to a video extension code setting and video playing method and system wherein the video extension code setting method comprises the following steps: reading the extension information from a preset video file; according to the extension information, setting extension codes; identifying a network abstraction layer unit from the framework of the video file and identifying the extension fields in the network abstraction layer unit; adding the extension codes to the extension fields; updating the network abstraction layer unit and saving the video file. The video extension code setting and video playing method and system of the invention enable a corresponding video to carry more information and increase the carrying amount of the corresponding video. Since the above video can be played via more players, for instance, the special players corresponding to the extension information or other universal players, procedures required by the user to play the video can be reduced.

Description

technical field [0001] The invention relates to the technical field of video signal processing, in particular to a video extension code setting and video playing method and system. Background technique [0002] Video can carry various dynamic and static information, and plays a vital role in information transmission. Usually, the above-mentioned video is formed by encoding related video files and their frames and other information. The frame of a video file includes two levels: Video Coding Level (VCL) and Network Abstraction Level (NAL); Network Abstraction Level The video format information and the feature information of the video player corresponding to the above-mentioned video are stored through the network abstraction level unit therein. [0003] The video obtained by encoding the above-mentioned video files in the traditional solution can usually only be played on one of the general-purpose players and the special-purpose players, which has certain playback limitatio...
