Embodiment Construction

[0043] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0044]The media file format is a unique file format. Its primary design goal is to be able to describe data and save data. It can not only save audio and video data, but also reflect playback-related characteristics, such as decoding type, audio and video synchronization information. , rate information, description information related to copyright authors, etc. In order to describe the data more effectively and expand it at will, the present invention establishes a binary XML format (hereinafter referred to as EBXML) on the basis of referring to XML rules and combining media files with binary data block storage. This binary XML is used to describe and parse media data.

[0045] First introduce the XML format. XML is a structured...

Abstract

The invention discloses a method and a system for playing a media file, as well as a media player, which aims to solve the problems that the prior media file format and the corresponding matching playing mode are incompatible with a third-party code, as well as the soundtrack support is limited. The method comprises: reading format information of the media file, wherein the format of the media file is predefined in a tree structure, and comprises a file header and the node attribute of the tree structure, each node is corresponding to different media streams respectively, and each node defines own attribute information; analyzing the file header and acquiring the each node attribute of the media file; searching decoders of the corresponding node data according to each node attribute; and reading each node data, and decoding and playing by use of the corresponding decoders. The media file format can be added arbitrarily; nodes with frequency, video, caption, interaction and other attributes can be defined; and the number of the node is not limited, so that the invention can support all node attributes such as the frequency, the video, the caption, the interaction and custom.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a media file playing method, a playing system and a media player. Background technique [0002] A media file is a file that combines information such as video, audio, subtitles, and pictures. Currently common media file formats include AVI, RM, WMV (or WMA), QT, etc. Common media players include Windows Media Player, RealPlayer, Baofengyingyin, etc. These players basically use the plug-in mode, so that they can be Native playback of most common media formats. [0003] AVI has been developed for 10 years. Internally, it adopts a step-by-step mode of audio and video data interaction, which solves the synchronization and addressing problems of audio and video, and is compatible with third-party encoding algorithms. But AVI usually only supports one channel, and AVI1.0 is also limited by size and cannot exceed 1G. The AVI2.0 that appeared subsequently corrected the problem of bei...
