Video transmission method and device, electronic equipment and readable storage medium

Abstract

The embodiment of the invention provides a video transmission method and device, electronic equipment and a readable storage medium. Video source data in a video cache queue is encoded; correspondingrandom access frames in different video cache queues are enabled to be acquired image frames at the same moment; adding a parameter set containing the code rate, the spatial resolution, the time resolution and the random access frame time interval of a data code stream obtained by encoding of each video encoder in a plurality of video encoders at the same time; therefore, the sending end can sendthe data in the case of bandwidth fluctuation; the method comprises the following steps: receiving packet loss information of current video reconstruction data obtained by decoding sent by a decoder and network time delay data of the current video reconstruction data reaching the decoder; and switching data code streams in real time in combination with the parameter set, so that a decoder decodesthe data code streams to obtain video reconstruction data, and the video reconstruction data displays clearer and smoother pictures.

Description

technical field [0001] The present invention relates to the technical field of video source data encoding and transmission, in particular, to a video transmission method, device, electronic equipment and a readable storage medium. Background technique [0002] Traditional video surveillance systems are generally built in a dedicated network. For example, the camera, storage server, and client are located in a dedicated video surveillance LAN. The client can decode the video code stream through the decoder to watch the real-time video image of the camera, or watch the historical video image in the storage server on demand. The closed video surveillance system is separated from the Internet, and the network bandwidth in the dedicated video surveillance local area network is guaranteed. In the dedicated video surveillance local area network, Real-time Transport Protocol (RTP) is generally used. ) to transmit the video stream. [0003] However, with the development of video su...

Problems solved by technology

Under such circumstances, when using traditional RTP to transmit video images, since the bandwidth of the Internet cannot be guaranteed, the real-time video images transmitted to the decoder or the video images in the on-demand storage server may be due to fluctuations in the network bandwidth of the Internet. characteristics, resulting in the client's video image viewing quality cannot be guaranteed
