Abstract

The invention relates to a video playing method, comprising: analyzing the video to obtain the original size of the video and the video rotation angle when the video is recorded; according to the original size of the video, obtaining the video rotated by the video rotation angle Image size; determine the playback mode of the video after the video rotation angle is rotated according to the video image size; the playback mode is one of a horizontal screen playback mode and a vertical screen playback mode; according to the playback mode, the The canvas is rotated to match the current screen posture; the size of the canvas conforms to the original size of the video; the image data decoded from the video is rotated according to the video rotation angle; the rotated image data, Draws into the canvas following the canvas's rotation. The video playing method provided by the present invention can avoid confusion of image orientation during video playing as much as possible.

Description

technical field [0001] The present invention relates to the technical field of computers, in particular to the technical field of video playing, in particular to a video playing method and device. Background technique [0002] Video is a kind of media data that stores dynamic images. After decoding the video frames from the video, each video frame is displayed sequentially according to a certain time interval. If the time interval is small enough, such as less than or equal to 1 / 24 seconds, the video frames are displayed sequentially. A dynamic picture will be formed, which can convey dynamic image information to the user. [0003] At present, when the video is recorded, it will form a video of a standard size, such as a video with a width of 1280 pixels and a height of 720 pixels. However, due to the difference in the posture of the recording device, the direction of the image in the video will be confused, and the video will be played according to the video. The standard ...
