First, a simple description is given to an implementation manner of adjusting a window size in the prior art with reference to fig. 1, where fig. 1 is a system diagram of an existing video window adjusting method.
As shown in fig. 1, where the browser 101 is configured to render the browser window 102, specifically, the browser 101 may, for example, recalculate the position and size of the browser window 102 after receiving a window scaling instruction, and further implement the rendering of the browser window 102.
Specifically, in the process of adjusting the video window according to the window scaling instruction, the video playing chip 102 receives video data from the browser 101 and decodes the video data, and meanwhile, the video playing chip 102 also receives the latest size and position of the video window 102 from the browser 101, so as to strive for keeping the size and position of the video window consistent with the position and position of the browser window 101.
Specifically, theoretically, the size and position of the browser window 103 and the video window 104 should be kept synchronously changed during the adjustment process, so as to be displayed on the screen 105, however, due to the problems of different processing speeds, information synchronization, and the like of the browser 101 and the video playback chip 102, black edges, jamming, delayed playback, and the like may occur on the screen 105.
Based on the foregoing problems, embodiments of the present invention provide a method for processing a video window, which is described in detail below with reference to specific embodiments.
Fig. 2A is a first system diagram illustrating a video window processing method according to an embodiment of the present invention. As shown in fig. 2A, includes: browser 201, video playback chip 202.
Specifically, the browser 201 is an application program for retrieving and presenting information resources of the world wide web, where the information resources may be, for example, web pages, pictures, videos, and the like, where the browser 201 may be, for example, a google browser, and may also be, for example, a firefox browser, and the like, and the specific type of the browser 201 is not particularly limited in the embodiment of the present invention.
Further, the video playing chip 202 is configured to process a video to be displayed when the browser displays the video, specifically, the video playing chip 202 may include, for example, a decoder, and the decoder decodes the video to be displayed to obtain image data of the video, where the image data of the video is a frame in the video.
In this embodiment, the browser 201 generally displays the acquired information resource in a window manner, that is, the browser window 203 illustrated in fig. 1, when the browser 201 is used to play a video, the video playing chip 202 sends image data of the video to be played to the video window 204, so as to display the video, where the browser window 203 and the video window 204 may be displayed in a nested manner, and the browser window 203 and the video window 204 may also be displayed separately, for example, this is not limited in the embodiment of the present invention, and sizes of the browser window 203 and the video window 204 may be adjusted according to an instruction triggered by a user.
Further, the browser window 203 and the video window 204 are presented on the screen 205, so that the display of the video by the browser is realized, where the screen 205 may be, for example, a screen of a computer, and may also be, for example, a screen of a television, and the embodiment of the present invention does not limit the specific model, size, and implementation of the screen, and those skilled in the art can understand that any display device of the device in which the browser 201 is installed can be used as the screen 205 in the embodiment of the present invention.
