Problems solved by technology

In the case of excessive CPU resource consumption, it will cause video playback to freeze, and the CPU temperature will also rise
After the CPU temperature rises, the processing speed will slow down more and more, the video playback will freeze, and in severe cases, the video playback terminal will even crash.

Embodiment Construction

[0022] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0023] figure 1 It is a flow chart of the method for reducing the CPU temperature of the video playback terminal provided by the present invention. Such as figure 1 As shown, the present invention provides a method for reducing the CPU temperature of a video playback terminal, the method comprising: detecting the frame rate of the video currently played by the video playback terminal; and when the frame rate is lower than the first preset Reduces the number of meta-operations performed on video frames at a lower value (e.g., 24 frames per second, which makes the playback feel smooth to the viewer).

[0024] During video playback, the CPU of the video playback...

Abstract

The invention discloses a device and method for reducing the CPU temperature of a video play terminal. The method comprises that the frame frequency of a video played by the video play terminal at present is detected; and under the condition that the frame frequency is lower than a first preset value, the amount of metal operations for the video frame is reduced. According to the technical schemes, the frame frequency of the video can reflect CPU resource or temperature to certain extent, the frame frequency is decreased when the resource is in short supply or the temperature is relatively high, and the video is jammed when being watched. Thus, the amount of metal operations of each frame is adjusted according to the frame frequency of the video, the burden of a CPU is alleviated and the CPU temperature is reduced when the resource of the CPU is in short supply, and it is ensured that the video is played smoothly.

Description

technical field [0001] The present invention relates to the field of information technology, in particular to a method and device for reducing the CPU temperature of a video playback terminal. Background technique [0002] Video playback terminal refers to electronic device products that can play videos stored in the form of digital signals, and generally contain video playback software. The video playback software carries a decoder to restore compressed media files. In addition, the video playback software also has a set of conversion frequency and buffering algorithms built in. [0003] As people's requirements for video clarity are getting higher and higher, the volume of current video files is also getting larger and larger. For example, a 1080p video file with a duration of 2 hours has a resolution of 1920×1080, and its volume Possibly up to 4G. When a video player program decodes and renders such a large-volume video file, it needs to occupy a large amount of resourc...
