Method and terminal for playing falsely-encapsulated audio/video files

Abstract

The invention provides a method and device for playing falsely-encapsulated audio / video files. The method comprises the steps of: comparing an audio / video file to be played with information characteristic point values with standard format corresponding to the audio / video file to be played one by one; resolving information when matched characteristic point values exist to obtain resolving information, and storing the resolving information in a temporary database; when the resolving information can correctly reflect the information of the whole falsely-encapsulated audio / video file, stopping the comparison of the information characteristic point values, and transmitting the resolving information stored in the temporary database to a decoding module of a player for playing. Based on an LINUX operation system, the method and the terminal can normally play the falsely-encapsulated audio / video files without interfering the work of a standard format resolver.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and a terminal for playing packaged and misplaced audio and video files based on a LINUX (an operating system) system. Background technique [0002] MKV is a media file of Matroska. Matroska is a new multimedia packaging format. It can encapsulate a variety of different encoded videos, more than 16 audios in different formats and subtitle streams in different languages ​​into a Matroska Media file. [0003] MKV is not a compression format, MKV is a new type of multimedia packaging format, also known as Multimedia Container (Multimedia Container). It is different from video encoding formats such as DivX and XviD, and also different from audio encoding formats such as MP3 and Ogg. MKV is just a "combination" and "encapsulation" format that provides shells for these audio and video. In other words, MKV is a container format, and common formats such as AVI, VOB, MPEG, RM...

AI Technical Summary

Problems solved by technology

[0006] Due to the existence of a large number of MKV packaging and packaging software at present, and the technical level of each software is different due to the writing company and individual, a large number of packaging and dislocation MKV video files appear. The playback information of this file is complete, but in terms of data structure, there is no MKV standard format for data combination, if it is analyzed according to the MKV standard format, the correct information cannot be obtained, so that the player cannot decode and play correctly

[0007] Especially based on the Linux operating system environment, audio and video files often cannot be played due to the dislocation of the audio and video information in the data.
