Embodiment Construction

[0057] In order to make the purpose, technical solution and advantages of the present disclosure clearer, the implementation manners of the present disclosure will be further described in detail below in conjunction with the accompanying drawings.

[0058]The video frame of video data can be divided into I frame (I frame), P frame (P frame) and B frame (B frame). Among them, I frame is also called intra picture (Intra Picture), intra-frame coding frame, which is the key Frame, usually the first frame in a video sequence, is an independent frame with all the information, retaining a complete picture, so it can be decoded independently without referring to other images when decoding; P frame is also called The forward prediction picture (Predicted Picture) retains the difference between this frame and the previous frame. Before decoding, it is necessary to superimpose the difference defined in this frame with the previously cached picture, generate the final picture, and then dec...

Abstract

The invention provides a sound and picture synchronization judgment method and device, a terminal and a computer readable storage medium, and belongs to the technical field of audio and video processing. The method comprises: obtaining first audio data corresponding to a target video frame of the first multimedia data received from a server, and determining first fingerprint information of the first audio data, comparing the first fingerprint information with at least one piece of second fingerprint information, and if the first fingerprint information is the same as any one piece of second fingerprint information, determining sound and picture synchronization of the first multimedia data. Because the fingerprint has uniqueness and can be used as an identifier of the audio data, the methodextracts the fingerprint of the audio data and judges the sound and picture synchronization according to the fingerprint, manual observation is not needed, the sound and picture synchronization judgment efficiency can be improved, errors caused by manual judgment can be avoided, and the judgment accuracy is improved.

Description

technical field [0001] The present disclosure relates to the technical field of audio and video processing, and in particular to a method, device, terminal, and computer-readable storage medium for judging audio-video synchronization. Background technique [0002] With the continuous development of computer technology, the leisure and entertainment industry relying on computers is also booming, and the live broadcast industry is becoming more and more recognized by the general public. From the very beginning of game live broadcast, to entertainment live broadcast, outdoor live broadcast, etc., live broadcast The curtain of the category. During an audio and video live broadcast, it is very important to synchronize the sound playback and screen display, that is, the synchronization of audio and video. Mistakenly thinking that the anchor was lip-syncing, it seriously affected the anchor's reputation. At present, judging whether the sound and the picture are synchronous is mai...
