Method for dynamically adjusting definition mode in video call, and server

Abstract

The present application discloses a method for dynamically adjusting a definition mode in a video call, and a server. In the method, a second terminal receives a remote video data stream uploaded by afirst terminal and forwarded by a server, and returns image frame rate data and audio code rate data in the remote video data stream and a packet loss rate of the first terminal to the second terminal link to the server; and the server determines a video coding parameter modification strategy of the first terminal according to the image frame rate data, the audio code rate data or the packet lossrate, and sends the modification strategy to the first terminal, so that the first terminal adjusts video coding parameters thereof according to the video coding parameter modification strategy. In the method, the server can accurately judge the quality of the network environment of the current video call according to the image frame rate data, the audio code rate data or the packet loss rate actually received by the second terminal, and the adjusted video coding parameters of the first terminal can adapt to the current network environment, so that the user experience is improved.

Description

technical field [0001] The present application relates to the technical field of video calls, in particular to a method and a server for dynamically adjusting the resolution mode in a video call. Background technique [0002] The video call function is a common function of smart terminal devices based on communication networks. The status of the communication network and the performance of the smart terminal device itself are important factors that affect the quality of calls. For example, the data processing capabilities of smart terminal devices, the set video encoding parameters (bit rate, image frame rate, and video resolution, etc.), as well as the bandwidth and signal strength of the communication network will affect the clarity, fluency and Call quality, etc. Among them, the bit rate refers to the data flow used by the video or audio file per unit time. Since the bit rate parameter is directly related to the size of the encoded video file, it is an important factor ...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned video call implementation method has at least the following defects: if the preset video encoding parameters of one end device are relatively high, which is suitable for high definition, but the network quality is not good, frequent freezes and frame loss will occur. Reduce call quality; if the preset video encoding parameters of one end device are lower, which is suitable for lower definition, but the network quality is better, it will waste device resources and network resources and affect user experience
