Problems solved by technology

Simply splicing m2ts files cannot meet the needs of producing correct content in many cases, and most of them need to use a lot of joint operations to achieve the goal, and the production efficiency is low
[0004] For the Bluray-DVD of the TV series type, there are still situations where multiple episodes are compressed in the same Bluray-DVD disc. It is impossible to separate the episodes simply by analyzing the m2ts file.

Abstract

The invention discloses a Bluray-DVD video positive content extraction system. The system comprises an analysis module, a selection preview module and a coding synthesis module, wherein the analysis module is used for extracting metadata of Bluray-DVD, and outputting Title number and description metadata of each Title; the selection preview module is used for providing audio / video playing and content edition; and the coding synthesis module is used for carrying out coding and deciding according to the description metadata so as to generate a target file. The Bluray-DVD video positive content extraction system starts with a playing theory of Bluray-DVD, and adopts a forward analysis way, so that the functions of any angle extraction, any subtitle selection, any audio track selection, automatic menu system stripping, automatic positive video content extraction, automatic TV series separation and automatic series synthesis can be effectively supported, and the content production efficiency can be greatly improved.

Description

technical field [0001] The invention relates to a Bluray-DVD video feature extraction system. Background technique [0002] When many content providers provide external films, they will transcode them into a common video format according to the requirements of the content purchaser, and the sources of the source films of the content provider include Bluray-DVD video format. [0003] For the Bluray-DVD video format, traditionally, the industry practice is to splice the m2ts files on the Bluray-DVD disc into a large file according to the file order and then transcode it into the target format. This approach is extremely risky, because the Bluray-DVD video format has multiple angles, multiple subtitles, menu navigation systems, etc. At the same time, the contents of the Bluray-DVD system are not simply played according to the order of the video sequence file names. Yes, the main title may be a large video file, or it may consist of multiple video files. Simply splicing m2ts f...
