Problems solved by technology

[0005] However, if the window playing the video (hereinafter referred to as: the window to be tested) is blocked, although the window may be displayed at this time, the picture cannot be seen. This situation is more difficult, and there is no good solution at present

Embodiment Construction

[0026] Such as figure 1 As shown, a method for detecting whether a window is blocked includes the following steps:

[0027] Take the current window A i The upper left corner of (1≤i≤n; i, n∈positive integer) is the origin, and the coordinates of its upper left corner are recorded as (x 1_Ai ,y 1_Ai ), the coordinates of the upper right corner are (x 2_Ai ,y 1_Ai ), the coordinates of the lower right corner are (x 2_Ai ,y 2_Ai ), the coordinates of the lower left corner are (x 1_Ai ,y 2_Ai );Such as figure 2 shown.

[0028] Note that the coordinates of the upper left corner of the window W to be tested are (x 1_w ,y 1_w ), the coordinates of the upper right corner are (x 2_w ,y 1_w ), the coordinates of the lower right corner are (x 2_w ,y 2_w ), the coordinates of the lower left corner are (x 1_w ,y 2_w );Such as figure 2 shown.

[0029] Step (1): Traverse the sibling windows and upper windows of the window W to be tested, namely the current window A i , ...

Abstract

The invention discloses a method for detecting window shielding. The method comprises the steps as follows: step 1, current windows Ai of a to-be-detected window are traversed, whether a single current window completely shields the to-be-detected window or not is detected, if yes, step 2 is executed, and otherwise, step 3 is executed; step 2, the to-be-detected window is judged to be shielded anddetection is finished; step 3, whether multiple current windows Ai completely shield the to-be-detected window, if yes, the step 2 is executed, and otherwise, step 4 is executed; step 4, the to-be-detected window is judged not to be shielded and detection is finished. Whether the to-be-detected window is shielded can be judged for either single or multiple current windows, and decoding and rendering are suspended for videos without pictures and continued otherwise, so that demands of clients for system configurations such as system hardware or IPC resolution ratio and the like are lowered.

Description

technical field [0001] The invention relates to a method for detecting whether a window is blocked. Background technique [0002] In the security industry, there is a kind of all-in-one machine, which is a combination of hardware and monitoring software. The monitoring software runs on the all-in-one machine. The commonly used function is to play the monitoring screen, and the video playback is obtained by the client from the front-end equipment, such as IPC. Video stream data , send it to the playback library for decoding, and then render the picture, so that the picture appears. Sometimes the hardware configuration of the all-in-one machine is too low, or the IPC resolution and other configurations are high, resulting in the preview screen not looking smooth or delayed. Part of the reason is that the system resources of the all-in-one machine are insufficient, which affects decoding and rendering. [0003] Similarly, in smart devices such as computers and mobile phones i...
