[0066] In this step S11, before playing the video, the terminal device reads the data of the video to be played, and obtains two sizes of the width and the height of the video.

[0067] S12. Determine whether the size of the video is compatible with the placement posture of the terminal device.

[0068] In the embodiment of the present invention, the placement posture of the terminal device includes a horizontal screen state and a vertical screen state, and the horizontal screen state is a state in which the height of the screen of the terminal device is smaller than the width of the screen, and the vertical screen state is the height of the screen of the terminal device. A state greater than the width of the screen.

[0069] Optionally, when the placement posture of the terminal device is a horizontal screen state, the height of the screen of the terminal device is smaller than the width of the screen, and then the height of the video is determined to be greater than the width of the video. When the height of the video is greater than the width of the video, it is determined that the size of the video does not match the placement posture of the terminal device; The height is less than or equal to the width of the video, and the size of the video is determined to be compatible with the placement state of the terminal device.

[0070] Optionally, when the placement posture of the terminal device is in a portrait state, the height of the screen of the terminal device is greater than the width of the screen, and then the height of the video is determined to be smaller than the width of the video. When the height of the video is smaller than the width of the video, it is determined that the size of the video does not match the placement posture of the terminal device. When the height of the video is greater than or equal to the width of the video, the size of the video is determined to be compatible with the placement state of the terminal device.

[0071] S13. When the size of the video does not match the placement posture of the terminal device, adjust the size of the video to match the size of the screen.

[0072] In step S13, when the size of the video does not match the placement posture of the terminal device, the terminal device does not rotate the video, but adjusts the size of the video until the size of the video matches the size of the screen.

[0073] Optionally, when the placement posture of the terminal device is a landscape state, the terminal device compares the height of the video with the height of the screen, and when the height of the video is greater than the height of the screen, the height of the video is reduced to the screen. The height is equal, and the ratio is reduced by the width of the video.

[0074] For example, assuming that the height and width of the video are h and w, respectively, the height and width of the screen are H and W, respectively, and h>H, the terminal device reduces the height of the video to H, and scales down the video. The width is w*H/h, that is, the height and width of the reduced video are H and w*H/h, respectively, so that the video is maximized and displayed on the screen.

[0075] Further, when the height of the video is smaller than the height of the screen, the terminal device increases the height of the video to be equal to the height of the screen, and increases the width of the video.

[0076] For example, suppose the height and width of the video are h and w, respectively, the height and width of the screen are H and W, respectively, and h<H, and the terminal device increases the height of the video to H, and increases in proportion. The width of the video is w*H/h, that is, the height and width of the enlarged video are H and w*H/h, respectively, so that the video is maximized and displayed on the screen.

[0077] In other embodiments, when the height of the video is less than the height of the screen, the video may not be adjusted.

. Of course, when the height of the video is equal to the height of the screen, there is no need to adjust the video.

[0078] When the size of the video is adjusted to match the size of the screen, the adjusted video is played. Playing Video 吋, it is preferable to place the video in the middle of the screen, and of course, the video can be placed on the left or right side of the screen as needed.

[0079] Optionally, when the placement posture of the terminal device is a vertical screen state, the terminal device compares the width of the video with the width of the screen, and when the width of the video is greater than the width of the screen, the width of the video is reduced to the width of the screen. The width is equal, and the height of the video is reduced.

[0080] For example, assuming that the height and width of the video are h and w, respectively, the height and width of the screen are H and W, respectively, and w>W, the width of the video is reduced to W, and the height of the video is reduced by h*W/w, that is, the height and width of the reduced video are W and h*W/w, respectively, so that the video is maximized and displayed on the screen.

Further, when the width of the video is smaller than the width of the screen, the terminal device increases the width of the video to be equal to the width of the screen, and increases the height of the video.

[0082] For example, assuming that the height and width of the video are h and w, respectively, the height and width of the screen are H and W, respectively, and w<W, the width of the video is increased to W, and the video is increased in proportion. The height is h*W/w, that is, the height and width of the enlarged video are W and h*W/w, respectively, so that the video is maximized and displayed on the screen.

[0083] In other embodiments, when the width of the video is less than the width of the screen, the video may not be adjusted. Of course, when the width of the video is equal to the width of the screen, there is no need to adjust the video.

[0084] When the size of the video is adjusted to match the size of the screen, the adjusted video is played. After playing video, it is preferred to place the video in the middle of the screen. Of course, you can also place the video on the top or bottom of the screen as needed.
