Embodiment Construction

[0041] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0042] One of the core concepts of the embodiments of the present invention is to call the media player to decode the video, and store the decoded video in the video memory; the GPU display module displays the video. In this application, the media player directly stores the decoded video in the video memory, and does not need to call the teximage2d function to import the video from the memory to the video memory, which saves the time of calling this function and improves the real-time performance of the preview video . In addition, the media player can timely delete video frames that take too long to decode, which further improves the real-time performance of the preview video and realizes real-time preview of the video, that is, ...
