Problems solved by technology

[0006] If the user chooses to start recording at this time, the recording device will only transfer the video data starting from 10:00:10 to the transcapsulation library for recording file generation, thus, the video file lacks the video data in the playback library buffer, There is a time deviation between the actual start time of the recording file and the expected start time (that is, the time displayed in the real-time preview screen)

Abstract

The present application provides a method, device and electronic device for generating a video file. The method includes: in a real-time video preview state, saving the acquired video data to a playback library buffer, and successfully saving it to the playback library buffer The video data is stored in the preset buffer; the target length of the video data decoded by the playback library is obtained; when in the video recording state, the video data of the target length in the front of the preset buffer is generated by the transfer package library video file. The method can avoid the time deviation between the actual start time of the video file and the time displayed in the real-time preview screen, and improve the accuracy of the video file generation.

Description

technical field [0001] The present application relates to video surveillance technology, and in particular, to a method, device and electronic device for generating video files. Background technique [0002] With the rapid development of video surveillance technology, the application of video surveillance technology has become more and more extensive, and the functions supported by video surveillance technology have become more and more abundant. [0003] The generation of video files based on real-time preview is a popular function of some video surveillance products. (Internet Protocol Camera, network camera)), and transmit the video data to the playback library for decoding and playback, so as to realize the real-time preview of the video data. When video recording is enabled, the video recording device transmits the acquired video data to the transpackaging library to generate video files. [0004] However, practice has found that in the current real-time preview-based...
