Problems solved by technology

[0003] In the cloud games of the prior art, there is a large amount of video and audio data transmission between the game server and the client. Unlike ordinary online games, since the transmission of cloud games is bidirectional, the tolerance of cloud games for transmission delay Much lower than ordinary online games, how to minimize network delay under the limitation of existing network bandwidth conditions has become one of the technical bottlenecks of cloud games

Abstract

The invention provides a video transmission method and device, and the method and device are used for a client, and the method comprises the steps: receiving video frames transmitted by a server, wherein each video frame comprises a plurality of data packages; analyzing the received video frame, and sending a first retransmission request to a server under the condition of determining that the video frame is lost, so as to enable the server to resend a lost data packet; and if it is determined that the first retransmission request fails, sending a second retransmission request to a server, so as to enable the server to send a complete video frame again after the video frame is sent, thereby realizing dual assurance for packet loss retransmission, solving the problem of packet loss and reducing network delay.

Description

technical field [0001] The present application relates to the technical field of the Internet, and in particular to a video transmission method and device, a computing device, and a computer-readable storage medium. Background technique [0002] In many games, the term network delay often appears, some players are high and some players are low. Network latency refers to the round-trip time it takes for a packet to travel from the user's computer to the web server, and then immediately from the web server back to the user's computer. [0003] In the cloud games of the prior art, there is a large amount of video and audio data transmission between the game server and the client. Unlike ordinary online games, since the transmission of cloud games is bidirectional, the tolerance of cloud games for transmission delay Much lower than ordinary online games, how to minimize network delay under the limitation of existing network bandwidth conditions has become one of the technical b...
