Abstract

The embodiment of the invention discloses a video frame synchronization method, system and device and a readable storage medium, and the method comprises the steps: collecting live streaming audio and video streams of a site in real time through a site collection device, and transmitting the collected live streaming audio and video streams to a video encoder in real time to serve as a to-be-processed video; enabling the video encoder to insert an SEI frame in front of each frame of the to-be-processed video, wherein the SEI frame carries a timestamp matched with a next video frame; sending the processed video frame to the cloud; enabling the cloud to analyze the timestamp of each path of video stream and calculate a reference timestamp; for each path of video, taking the reference timestamp as a reference, and selecting a frame with the minimum timestamp deviation as a current target synchronization frame so as to complete multi-camera frame synchronization. And cloud multi-channel video live streaming frame alignment is realized.

Description

technical field [0001] The embodiments of the present application relate to the technical field of live video broadcasting, and in particular to a video frame synchronization method, system, device, and readable storage medium. Background technique [0002] With the continuous maturity of network transmission technology and streaming media technology, multimedia live broadcast services provided through high-speed Internet are becoming more and more popular, and many online live broadcast platforms have emerged one after another. These webcast platforms provide users with extremely smooth and clear multimedia playback. Since the webcast platform is an Internet-based product, it can be combined with many Internet products to provide users with a more convenient experience. [0003] In various scenarios that require audio and video live broadcast, the existing technology uses the size of the buffer as the basis for synchronization. Therefore, if the network environment and har...
