Abstract

The invention is suitable for the technical field of computers, and provides a resolution switching method and device of a video. The method comprises the following steps: receiving a request of switching the current resolution of a video in playing to the second resolution, recording the video in playing as the first video, and recording the current resolution as the first resolution, continuously playing the first video, downloading the second video with the second resolution from a corresponding video server according to an identity of the first video, and caching the second video with the second resolution, wherein the content of the first video is the same as that of the second video; switching the first video in playing to the second video when the cache data of the second video is up to the preset size, thereby realizing the smooth switching from the first video to the second video, and improving the experience of watching the video of a user.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a video resolution switching method and device. Background technique [0002] With the development of smart mobile devices, video learning through smart mobile devices has become one of the after-school learning tasks of student users. Learning video providers provide learning videos with different definitions or resolutions according to different network speeds. When users When you want to switch to a video with a different definition during the process of learning the same video, it is difficult to download the video cache of the target definition in time, which will cause the current video playback to be paused to wait for the target video to be cached, making the video playback not coherent. It affects the continuity of user learning and reduces the experience of using the device. Contents of the invention [0003] The purpose of the present invention is to p...
