Abstract

The invention discloses a method and device for detecting video playback status. When a video playback thread starts, a first timer is started; if a map callback function is obtained within the set time of the first timer, a second timer is started timer; if the texture callback function is not obtained within the set time of the second timer, it is determined that the video playback error. The method and device for detecting the video playback state provided by the embodiments of the present invention detects the picture update through the callback when the map texture of the decoding result is refreshed, and judges whether the video is incorrectly played by whether the timer times out. The playing state is detected according to the result of playing the video, which improves the detection efficiency and practicability.

Description

technical field [0001] The invention relates to the technical field of image detection, in particular to a method and device for detecting a video playing state. Background technique [0002] Video player refers to software that can play video stored in the form of digital signals, and also refers to electronic device products with the function of playing video. A general video player consists of a decoding module (Codec) and a video display module (including Texture, Surface and Render). [0003] Existing video playback state detection systems such as figure 1 Shown, comprise decoding module 101, Codec realizes, realizes the function that video is decoded; Texture map module 102, specifically can realize by Texture, is used for storing the texture map of Codec decoding result, when decoder obtains the new one frame The decoding result will update the texture and trigger the texture update callback function. The texture display rendering module 103 can be realized specifi...
