Embodiment 1

[0021] like figure 1 As shown, this embodiment can provide a video and audio recording method, which is a technical solution for video and audio recording that can be based on an asynchronous state, and can achieve accurate alignment of video frames and audio frames. The method includes, but is not limited to, the following steps that can be cyclically executed multiple times.

[0022] This embodiment may be implemented in a thread mode, and a thread is started to perform video and audio matching. First, a frame of current video and video timestamp is read from the video buffer, and a frame of current audio and audio timestamp corresponding to the current video is read from the audio buffer. It should be understood that "current video" refers to a frame of video to be processed during the execution of this process, and "current audio" refers to the current video corresponding to the current video during the execution of this process to be processed during the execution of thi...

Embodiment 2

[0032] The video and audio recording method in Embodiment 1 is based on the same inventive concept, and this embodiment can provide a product corresponding to the video and audio recording method in Embodiment 1, that is, this embodiment can provide an audio and video recording apparatus.

[0033] The device includes, but is not limited to, a data reading module, a synchronization judgment module, a delay detection module, a data insertion module, a data deletion module, etc. The working modes and principles of each module are specifically described as follows.

[0034] The data reading module is used for reading a frame of current video and video time stamp from the video buffer, and for reading a frame of current audio and audio time stamp corresponding to the current video from the audio buffer.

[0035] The synchronization judgment module judges whether the current video and the current audio are synchronized according to the time stamp, and is specifically configured to us...

Abstract

The invention discloses a video and audio recording method and device, and a computer-readable storage medium. The method includes: reading a frame of current video and video time stamps, a corresponding frame of current audio and audio time stamps, and judging whether the video and audio are If the first synchronization condition is satisfied, put it into the encoding buffer when it is satisfied, and judge whether the subsequent multi-frame video and multi-frame audio do not meet the second synchronization condition when not satisfied: if so, delete the current video or audio, if not , then put it into the coding cache; the device includes a data reading module, a synchronization judgment module, a delay detection module, a data insertion module and a data deletion module; a program is stored on the readable storage medium, and the program is executed by the processor, In order to realize the above recording method or recording device. The present invention only needs to use general cameras and video and audio boards, so the price of products applying the present invention can be accepted by more customers, and the present invention can fully meet the needs of users in terms of synchronization effect.

Description

technical field [0001] The present invention relates to the technical field of video and audio recording, and more specifically, the present invention relates to a video and audio recording method and device, and a computer-readable storage medium. Background technique [0002] At present, there has been a long-standing problem in video and audio recording that cannot be avoided, that is, how to achieve a better balance between the continuity of the video picture and the synchronization of the video and audio, in other words, how to keep the sound and the picture always synchronized. At no cost, each device can be synchronized and matched by using an audio and video synchronization signal source, so as to achieve precise alignment of video and audio. Although the video and audio synchronization signal source can be used to solve the problem of the audio and video recording being out of sync with the picture, the production cost of the video and audio synchronization signal s...
