Indexing system and method supporting MOV (Movie Digital Video Technology)/3GP (3G Player)/MP4 (Mobile Pentium 4) files

Abstract

The invention discloses an indexing system and a method supporting MOV (Movie Digital Video Technology) / 3GP (3G Player) / MP4 (Mobile Pentium 4) files. The indexing system comprises an index file header module, a primary index module and a secondary index module. The index file header module is used to record the basic information of the file header of a video and audio file, in particular the basic file information of all the pre-written data streams and the whole information of the video and audio data streams copied after the index file is established. The primary index module is used to store the primary indexing of the video and audio file, in particular the data stream information written back when the secondary indexing amount surpasses the preset amount. The secondary index module is used to store the secondary indexing of the video and audio file, in particular the information recorded by all the samples of the video and audio file. Through the indexing system and the method disclosed by the invention, the reading and inquiring efficiency is greatly improved and the storage room of the internal memory of the system is reduced.

Description

technical field [0001] The invention relates to the technical field of program production, in particular to an indexing system and method supporting MOV / 3GP / MP4 files. Background technique [0002] The streaming media service is a characteristic service in the video field, and it is an urgent demand for efficient video recording and accurate and flexible playback of video content. [0003] The exact flexibility of playback depends on the multi-party data storage strategy and playback strategy. In streaming media services, streaming media files are mostly stored in MOV / 3GP / MP4 format. [0004] MOV format files are organized in the form of tracks. A MOV format file structure can contain many tracks. There are some empirical values ​​for the limit of the number of tracks, and these values ​​will change as the computer becomes more and more powerful. However, the MOV format file itself does not have a predefined limit for the number of tracks. [0005] 3GP is a video encodin...
