Embodiment Construction

[0108] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0109] The following briefly introduces the application field of the method for displaying video provided by the embodiment of the present application.

[0110] As technology continues to develop, more and more devices can display video. In order to ensure the continuity of the video display, the device continuously receives the video frames of the video, and continuously caches the received video frames in the storage space. When displaying the video, it reads each video frame in turn for display.

[0111] However, since the process of buffering the video frame and the process of reading the video frame are independent of each other, it is easy for the dev...

Abstract

The invention provides a method for displaying a video and a method and device for caching a video frame, which are used for solving the problem that an abnormal display condition is easy to occur in a video display process. The method comprises the following steps: based on a storage space set, obtaining a first target storage space which is indicated by a write pointer and is used for caching a received video frame, and obtaining a second target storage space which is indicated by a first read pointer and is used for caching a next to-be-displayed video frame of the video; if the first target storage space is not matched with the second target storage space, updating a second read pointer to indicate the second target storage space based on the first read pointer, wherein the second read pointer indicates a storage space used for caching a video frame currently displayed by a video; reading the video frame to be displayed in the second target storage space indicated by the second read pointer, and updating the currently displayed video frame of the video.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to a method for displaying video, a method and device for buffering video frames. Background technique [0002] As technology continues to develop, more and more devices can display video. In order to ensure the continuity of the video display, the device continuously receives the video frames of the video, and continuously caches the received video frames in the storage space. When displaying the video, it reads each video frame in turn for display. [0003] However, since the process of caching video frames and the process of reading video frames are independent of each other, it is easy for the device to read out and display the video frames being cached when reading video frames, because the video frames being cached have not been cached yet , so part of the screen displayed by the device may belong to the video frame being cached, and the other part may belong ...
