Problems solved by technology

[0005] In the above scheme, if the server receives the video request sent by the client just after an I frame has flowed through the video data stream acquired by the server, in this case, the server needs to wait for a long period of time to wait for the video data stream to be processed again. An I frame appears, that is to say, after the client sends the video request, it needs to wait for a long time to get the feedback from the server, and a black screen will appear on the client

Abstract

The embodiment of the invention discloses a real-time video transmission and playing method and device. The method includes the following steps: after receiving a video request sent by a client, a server sends a cached current I-frame and an acquired current video data stream to the client; and the client decodes and plays data frames before the first I-frame in the current video data stream according to the current I-frame, and ensures that no blank screen phenomenon occurs. In other words, video data of only one I-frame is cached in the server, the caching of the video data of one GOP is notneeded, and thus the memory resource occupancy rate of the server can be reduced.

Description

technical field [0001] The invention relates to the field of video technology, in particular to a real-time video transmission and playback method and device. Background technique [0002] In some scenarios where video data is acquired in real time, such as live broadcast or monitoring, the server acquires video data streams in real time from video acquisition devices. Users can watch real-time video through mobile phones, tablets, computers and other clients. [0003] The specific process may include: the client sends a URL (Uniform Resource Locator, Uniform Resource Locator) request to the server, and the server establishes a connection with the client after verifying that the client is legal. After the connection is established, the server can send the real-time video data stream requested by the client to the client. [0004] Video data generally consists of multiple GOPs (Group Of Picture, Group Of Pictures), and one GOP includes an I frame (internal picture frame) an...
