Abstract

The invention relates to a method for connecting and outputting video files. The method comprises the following steps of: 1, performing timestamp smoothing processing on at least two decoded video files; 2, aligning the at least two video files after timestamp smoothing processing; and 3, encoding, synthesizing and outputting the at least two aligned video files. The step S1 comprises the following steps of: 11, repeating or losing video frames of the decoded video files to make the video frames output according to a preset frame rate; and 12, complementing silence or deleting corresponding audio data of audio frames of the decoded video files to make the audio frame aligned according to a theoretical timestamp. The invention also relates to a video file connecting and outputting device. The method and the device for connecting and outputting the video files can connect a plurality of input video files into one video file and output the video file, and can guarantee the play speed and the synchronization degree of the output video and the output audio.

Description

technical field [0001] The invention relates to the field of video production, in particular to a method and device for connecting and outputting at least two video files. Background technique [0002] With the popularity of iPhone, iPod and other 3G mobile phones and hardware players, people need to convert various media files into formats that can be played on such devices, and various format conversion software has emerged as the times require. However, these software can only convert the format of a single media file. Some video editing enthusiasts need to cut, combine, and connect multiple media files into one file for output. However, the current audio and video transcoding software cannot convert multiple files. , concatenated into a single file output. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method that can connect multiple input video files into A video file output video file connection outpu...
