Video stream synchronization method and apparatus, platform, and storage medium

A video stream synchronization platform, wherein the video stream synchronization platform comprises a main control module, a frame synchronization control module, an input node and output nodes;

• wherein
• the input node is configured to, for each video frame in a video stream, segment a current video frame to generate at least two video blocks;
• the input node is further configured to, for each of the at least two video blocks, transmit a current video block to an output node corresponding to the current video block, and in response to a completed transmission of the current video block, send a message packet to the output node corresponding to the current video block, wherein the at least two video blocks have one-to-one correspondence with at least two of the output nodes, the message packet comprises a first video identification of the current video frame and a first frame number identification of the current video block, a plurality of video frames in a same video stream have a same first video identification, and the at least two video blocks generated by segmenting a same video frame have a same first video frame number identification;
• the input node is further configured to send the message packet to the frame synchronization control module through the main control module in response to a completed transmission of the at least two video blocks generated by segmenting the same video frame and the message packet;
• and
• the frame synchronization control module is configured to, in response to the message packet, process an initial frame synchronization signal according to the first video identification and the first frame number identification in the message packet, generate a target frame synchronization signal, and send the target frame synchronization signal to the output nodes corresponding to the at least two video blocks respectively;
• wherein
• for each of the output nodes, a current output node parses the target frame synchronization signal to determine a second video identification and a second frame number identification, and in response to the first video identification being the same as the second video identification and the first frame number identification being the same as the second frame number identification, sends a video block corresponding to the first frame number identification in the current output node to a display device.
