Problems solved by technology

In this way, during video transmission, it is impossible to set different frame rates for videos with different resolutions, so that the higher the resolution, the lower the fluency of the video, and the phenomenon of stuttering often occurs, resulting in a decrease in the quality of video communication

Embodiment 1

[0069] figure 1 It shows a schematic flowchart of the video transmission method provided by the embodiment of the present application, the method includes steps S101-S104; specifically:

[0070] S101. For each coded stream, according to the ratio of the target coded stream to the initial frame rate of the coded stream, send the video frame to the video encoder of the coded stream to obtain the coded stream to be transmitted, wherein the target coded stream is An encoded stream with the highest resolution among the encoded streams.

[0071] Specifically, the frame rates of video encoders corresponding to encoded streams with different resolutions are different. The higher the resolution of the encoded stream, the higher the frame rate of the corresponding video encoder. Using the maximum frame rate of each video encoder rate, different frame rates can be set for each encoded stream with different resolutions. In this way, the frame rate requirements of encoded streams with di...

Abstract

The invention provides a video transmission method and device, and the method comprises the steps: transmitting a video frame to a video encoder of a coding stream according to the ratio of a target coding stream to the initial frame rate of the coding stream for each coding stream, so as to obtain a to-be-transmitted coding stream; for each to-be-transmitted coding stream, allocating a code rateto the to-be-transmitted coding stream according to a preset code rate allocation rule to obtain a first code rate corresponding to the to-be-transmitted coding stream; acquiring a default code rate corresponding to the to-be-transmitted coding stream, if it is determined that the first code rate is greater than the default code rate, calculating a second code rate corresponding to the to-be-transmitted coding stream, and allocating a bandwidth corresponding to the second code rate to a target to-be-transmitted coding stream to obtain a transmission bandwidth corresponding to the target to-be-transmitted coding stream; and based on the bandwidth requirement of the current client, sending a to-be-transmitted coding stream conforming to the bandwidth requirement to the current client. The video communication quality can be improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular, to a method and device for video transmission. Background technique [0002] With the continuous development of digital media technology, in daily life, video communication has become an important communication method for people to communicate remotely, for example, video conferencing, live video broadcasting on the Internet, and the like. When performing multi-terminal video communication, each communication client often has different requirements for network bandwidth. In order to ensure the video quality of each client during communication, how to transmit video for each client that meets the client’s network bandwidth requirements has become A technical problem that needs to be solved urgently in the field of current communication technology. [0003] In the current method, the video to be transmitted is divided into different grades according to the resolution....
