Optionally, the first aspect ratio corresponding to the canvas size may be calculated according to a ratio of the width to the height in the canvas size; the second aspect ratio corresponding to the window size may be calculated from a ratio of the width and the height of the window size. Of course, since the canvas size of the video is predetermined, if the first aspect ratio exists in the data stream corresponding to the video, the first aspect ratio may be directly obtained; if the application for playing the video already has information corresponding to the second aspect ratio, the second aspect ratio can also be directly obtained through the application.
Optionally, the terminal may compare the first aspect ratio and the second aspect ratio after obtaining the two aspect ratios. When the first aspect ratio is not equal to the second aspect ratio (i.e., the first aspect ratio is greater than the second aspect ratio, or the first aspect ratio is less than the second aspect ratio), a target canvas size is determined from the canvas size and the window size.
Wherein, when the first aspect ratio is larger than the second aspect ratio, the height H in the window size is obtained2Height H as target canvas size3According to the height H in the window size2And a height H in the canvas size1The ratio between and the width W in the canvas size1Determining a width W in the target canvas size3(will width W)1Multiplied by the height H2And height H1The ratio therebetween). Width W in target canvas size3The specific calculation formula of (2) is as follows:
when the first aspect ratio is smaller than the second aspect ratio, then the width W in the window size is obtained2Width W as target canvas size3According to the width W in the window size2And a width W in the canvas size1The ratio between and the height H in the canvas size1Determining a height H in the target canvas size3(will height H)1Multiplied by the width W2And width W1The ratio therebetween). Height H in target canvas size3The specific calculation formula of (2) is as follows:
thus, whether the first aspect ratio is greater than the second aspect ratio or the first aspect ratio is less than the second aspect ratio, it can be achieved that the target canvas size determined to be greater than the window size (i.e., the product of the width and the height in the target canvas size, which is greater than the product of the width and the height in the window size) is achieved, and at the same time, the third aspect ratio (calculated from the ratio of the width and the height of the target canvas size) corresponding to the target canvas size is equal to the first aspect ratio of the canvas size.
And step S30, playing the video in the display window according to the size of the target canvas.
