Abstract

The embodiment of the present application discloses a multimedia data processing method, system and storage medium, wherein the method includes: obtaining a source video file, obtaining a video data source and an associated data source from the source video file; obtaining a scene associated with the video data source The key frame slices the initial video sequence of the video data source according to the key frame of the scene to obtain the video slice associated with the initial video sequence; when the encoding parameters associated with the video slice are obtained, the video slice is transcoded, A video transcoding sequence associated with the video slice is obtained; according to the duration information of the video transcoding sequence, the associated data source is sliced ​​to obtain an associated slice having the same duration as the video transcoding sequence. By adopting the embodiment of the present application, the stability of video quality in the same video slice can be improved, and the synchronization of audio and video after video transcoding can be ensured.

Description

technical field [0001] The present application relates to the technical field of the Internet, and in particular to a multimedia data processing method, system and storage medium. Background technique [0002] At present, for some video data composed of frame sequences, these video data can be sliced ​​by the same encoder to obtain video slices with different complexity. However, in the process of video encoding these video slices in the prior art, Usually, fixed encoding parameters (for example, fixed encoding rate) are used for indiscriminate encoding. For example, for video data A and video data B with different complexities, a fixed coding bit rate is used to perform video coding on the two video data, so that the video quality of the video data obtained after video coding is between There will be large fluctuations, and it is difficult to ensure the stability of the video quality after video transcoding.
