Abstract

The invention discloses a multimedia file splicing method. The method comprises the steps of obtaining a plurality of to-be-spliced source multimedia files, and determining a target audio attribute; generating a mute audio data stream which matches the total playing duration of the plurality of source multimedia files and has the same attribute as the target audio; performing unified format processing on the audio data streams in the plurality of source multimedia files to obtain audio data streams with the same attribute as the target audio; and splicing the audio data streams subjected to the unified formatting processing, and mixing the spliced audio data streams with the mute audio data stream to obtain a spliced audio mixing data stream. Therefore, the phenomena of abnormal splicing,incapability of playing and the like caused by inconsistent audio attributes or audio loss of the source multimedia file are avoided. The invention further discloses a corresponding device, equipmentand a medium.

Description

technical field [0001] The present application relates to the technical field of audio and video processing, in particular to a multimedia file splicing method, device, equipment and medium. Background technique [0002] Multimedia file splicing technology refers to splicing multiple multimedia files to form a multimedia file. At present, multimedia splicing technology is widely used in the field of audio and video processing. Typical application scenarios include music editing scenes, TV drama movie editing scenes, etc. In these scenarios Next, it is necessary to realize audio splicing or audio and video splicing based on multimedia file splicing technology. [0003] At present, when splicing audio or audio and video, it is often encountered that the audio stream in the source multimedia file is not standard, for example, some video files do not have a corresponding audio stream, the audio stream data is not continuous, and the audio stream corresponding to multiple audio s...
