Error correction method and system for distributed video transcoding

Abstract

An embodiment of the present invention provides an error correction method for distributed video transcoding, comprising: the decapsulation server decapsulates the video file to obtain at least one GOP and at least one audio package, and assigns numbers to at least one GOP and the audio package; decapsulation The server sends the GOP and audio packets to the transcoding server; the transcoding server checks the correctness of the received GOP and audio packets; the transcoding server transcodes the correctly received GOP and audio packets; the transcoding server converts the transcoded GOP and audio packets are sent to the encapsulation server; the encapsulation server detects whether all transcoded GOPs and audio packets have been received; after the encapsulation server detects that all transcoded GOPs and audio packets have been received, the transcoded GOP And the audio package is encapsulated into a transcoded video file. The embodiment of the invention also provides a corresponding error correction system. Through the embodiments of the present invention, errors in distributed video transcoding can be corrected to the greatest extent, and the correctness of distributed video transcoding can be improved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to an error correction method and system for distributed video transcoding. Background technique [0002] When a large number of videos need to be converted, multiple stand-alone transcoding software can be used for transcoding; and a more efficient method is to design a distributed transcoding system for transcoding. Distributed video transcoding can generally be divided into four steps: a, decapsulation, b, video decoding and encoding, c, audio decoding and encoding, d, encapsulation. Among these four steps, the video decoding and encoding step takes 80%-90% of the entire transcoding process. In order to improve the transcoding speed and reduce the overall time of transcoding, the core is to reduce the processing time of video decoding and encoding. [0003] The idea of ​​distributed transcoding is to use multiple servers to simultaneously decode and encode GOP (Group of Pictu...
