Abstract

The invention provides an adaptive video definition adjusting method, apparatus and terminal. The adaptive video definition adjusting method provided by the invention comprises the following steps: detecting a current CPU load detection parameter of a terminal device participating in a video call in a video call process; judging whether the current CPU load detection parameter reaches a preset peak value, and if judging that the current CPU load detection parameter reaches the preset peak value, reducing the definition parameter of the video according to a predetermined adjustment strategy, wherein the definition parameter of the video comprises resolution, a code rate and / or a frame rate of the video. According to the adaptive video definition adjusting method provided by the invention, the definition parameter of the video is dynamically and adaptively adjusted via CPU load detection and network bandwidth detection and the like, so as to guarantee the normal operation of the video call and guarantee better smoothness as well.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and terminal for self-adaptive adjustment of video definition. Background technique [0002] With the rapid development of wireless communication technology, at present, video calls have gradually become an indispensable means of communication in people's daily work and life. In the existing video call technology, the video resolution is set to a fixed video resolution through initialization conditions, and is kept throughout the entire video call. [0003] The disadvantage of the above-mentioned existing video call implementation is that during the call, when the CPU usage rate of the mobile terminal device is too high, the memory is insufficient, or the network speed is too low, if the previously set initial Parameters, it will cause the video interface to freeze, blur and so on. Moreover, when the CPU load of the mobile terminal is too heavy, ...
