A Transcoding Method for Video Files of Any Format

Abstract

A method for transcoding a video file in any format, comprising: obtaining the properties of the video file to be transcoded and the transcoding requirements of the target file, and creating at least two sets of transcoding process modules; The working mode of the transcoding process module, and create the components of the transcoding process module; the video data reading module reads the video frame by frame, attaches the necessary information and passes it to the transcoding process module; the transcoding process module according to its own working mode, press Transcode video frames in parallel according to the rules; write the video frames generated by transcoding into the target file. The invention avoids the additional time-consuming problems caused by the division of the video file to be transcoded and the repeated transmission of video data on the network. At the same time, for video files in any format and any reasonable transcoding requirements, the transcoding method can be fast, efficient and efficient. stable implementation.

Description

technical field [0001] The invention relates to the field of audio and video streaming media, in particular to a method for transcoding video files in any format. Background technique [0002] In recent years, with the rapid development of network and communication technology, various applications in video conferencing, video surveillance, high-definition movies and other video fields can be seen everywhere in people's daily life. The above-mentioned common applications will save video data as video files for Users view historical videos online. Due to the variety of saved video file formats, and at the same time, the way users view video files online is not uniform, which is doomed to confirm that the format of video files cannot be successfully accessed online by all users. In view of this, video files need to be transcoded to generate other formats. video files to ensure that every user can successfully access historical video files. In addition, video files may contain...

Problems solved by technology

This transcoding method has certain practicability, but it has the following disadvantages. First, the video file to be transcoded is divided into sub-files, and the sub-files generated by transcoding are merged into the target file. These two processes may affect the transcoding process. Factors of code quality, such as the sub-files to be transcoded cannot be decoded normally, the combination of sub-files generated by transcoding causes the lip sound of the target transcoded file to be out of sync, and the process of merging sub-files generated by transcoding takes a long time, etc.; second, this transcoding method The usage scenarios are relatively limited, and the scope of application is not wide. For example, transcoding needs to generate target video files with high and low resolutions

[0006] There are also some video file transcoding methods disclosed in Chinese patents, which basically seek innovation in the schemes of segmenting the video file to be transcoded, or distributed transcoding sub-files, or generating target video files based on the media information of the file to be transcoded. point, these solutions all have some deficiencies briefly introduced in the three Chinese open patents listed above
