Problems solved by technology

[0004] The existing technology obtains the frame rate by looking up the code table, and its coding frame rate is uniquely determined by the current code rate, so it is difficult to adapt to changes in various scenarios
If the frame rate is set too high, the coded image will appear blurred, the image quality will drop, and even cause bit rate overflow, resulting in network congestion; if the frame rate is set too low, the video image will freeze, and the video playback will not fluent

Abstract

The invention provides a method and system for dynamically adjusting encoding frame rate in video communication. The method includes the following steps that: a video source sequence is acquired; the feature information of video images in the source video sequence is extracted; and encoding frame rate is calculated according to detected code rate and the feature information. The invention also provides a corresponding system for dynamically adjusting encoding frame rate in video communication. The method and system of the invention can adaptively adjust the encoding frame rate and satisfy requirements of video image quality and video smoothness.

Description

technical field [0001] The invention relates to the technical field of video communication, in particular to a method for dynamically adjusting the encoding frame rate in video communication, and a system for dynamically adjusting the encoding frame rate in video communication. Background technique [0002] In existing Instant Messaging (IM, Instant Messaging) applications, video communication is a common application. [0003] In real-time video communication, the network bandwidth often changes, and the unstable network environment will cause the encoding bit rate of the encoder to change accordingly. When the bit rate fluctuates, how to choose an optimal encoding frame rate is very important. The current technical solution basically adopts the method of empirical value, that is, according to the current bit rate, the preset code table is searched to obtain a corresponding encoding frame rate. [0004] The existing technology obtains the frame rate by looking up the code t...
