Abstract

The embodiment of the invention provides a method for transcoding an audio and video file. The method comprises the steps that (a) audio and video separation is conducted on an audio and video source file, and then an audio file and a video file are formed; (b), the video file is sliced, and a plurality of video file sections are obtained; (c), the video file sections and the audio file are respectively transcoded; (d), the transcoded video file sections are combined, and then a transcoded video file is obtained; (e), the transcoded audio file and the transcoded video file are combined into one file. By the adoption of the method for transcoding the audio and video file, the problem that audio content and video content of a transcoded file are not synchronous can be solved. In addition, the invention provides a device for transocding the audio and video file.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of image processing, and more specifically, embodiments of the present invention relate to methods and devices for transcoding audio and video files. Background technique [0002] This section is intended to provide a background or context for implementations of the invention that are recited in the claims. The descriptions herein may include concepts that could be explored, but not necessarily concepts that have been previously thought of or explored. Therefore, unless otherwise indicated herein, what is described in this section is not prior art to the description and claims in this application and is not admitted to be prior art by inclusion in this section. [0003] Multimedia transcoding refers to converting a compressed and encoded multimedia code stream into another multimedia code stream to adapt to different network bandwidths, different terminal processing capabilities, or di...
