detailed description

In order to make the objects, technical solutions, and advantages of the present application more comprehensible, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the application and are not intended to be limiting.

Further, the technical features involved in the various embodiments of the present application described below may be combined with each other as long as they do not constitute a conflict with each other.

In the embodiment of the present application, due to the limitation of the screen size, when the video content is played, only part of the content of the same video segment may be presented on the screen, and some content may not be presented on the screen, especially in the full screen of the vertical screen. At the time, only part of the content can be presented on the screen. In the full-screen playback mode of the vertical screen, the height of the video playback content will occupy the entire physical height in the vertical state of the screen, and the width of the video playback content will be enlarged according to the height of the video playback content. The scale is scaled up. Therefore, the content of the video playback includes the content presented by the screen and the content that is not presented by the screen. For the content that is not presented, the content needs to be switched according to the moving direction of the screen.

The video of the embodiment of the present application may be a video file with different resolutions, especially an ultra high definition video file, for example, a video with a resolution of 4K. For the ultra high definition video in the full screen playback mode of the vertical screen, the mobile screen can be seen through the mobile screen. More details of the video.

In the embodiment of the present application, the mobile playing terminal may be a mobile intelligent terminal, or may be a portable terminal such as a tablet computer or an audio/video file player.

S11. Obtain a positional relationship between the screen rendered content and the unpresented content in the video playing content.

In the embodiment of the present application, during the video playing process, due to the limitation of the screen size, the entire content of the video playing content cannot be completely presented. For example, for the ultra high definition video in the full screen playing mode of the vertical screen, in order to realize the user viewing more The video content details, the video content is enlarged, the height of the video playback content will occupy the entire physical height in the vertical state of the screen, and the width of the video playback content will be scaled according to the height of the video playback content, for example, The currently playing video occupies a height of 1.5 inches in the vertical state of the screen, a width of 2 inches, and a physical height of 4 inches in the vertical state of the screen, and the magnification ratio is 8/3. At this time, the currently playing video occupies the screen vertical. High in state The magnification is up to 4 inches and the width is 16/3. The enlarged current video width will exceed the physical width of the screen. Therefore, the current screen cannot simultaneously present the entire content of the video playback content to the user. In this case, the video playback content There are screen presentations and unpresented content.

In the embodiment of the present application, in order to obtain a positional relationship between the screen presentation content and the unpresented content in the video playback content, an image position relationship in the video playback content may be acquired, and the presented content and the unpresented content are determined according to the image location relationship. The positional relationship and the positional relationship between the current screen presentation content and the unpresented content in the video playback content. For example, if the content presented on the screen is the middle part of the entire picture in the video playing content, the positional relationship between the unpresented part of the video playing content and the image may be determined according to the image presented in the picture, for example, the unpresented content is Whether it is on the left side of the rendered image or on the right side of the rendered image. The positional relationship between the presented content and the unpresented content is a horizontal positional relationship. Of course, for the 360-degree panoramic imaging, the positional relationship between the presented content and the unpresented content may be determined according to the angular relationship between the images.

S13. Determine a correspondence between the unpresented content and the screen moving direction according to the current screen position and the positional relationship between the presented content and the unpresented content.

In the embodiment of the present application, in order to implement switching of the rendered content and the unpresented content on the screen, the correspondence between the unpresented content and the screen moving direction may be determined according to the current screen position and the positional relationship between the presented content and the unpresented content. . For example, if the un-presented content is located on the left side of the rendered content, then moving the current screen to the left will present the un-presented content located to the left of the current rendered content, and for how many un-presented content is presented, it may be determined according to the magnitude of the moving screen.

S15. Switch the rendered content to the unpresented content corresponding to the screen moving direction according to a screen moving direction and a correspondence between the unpresented content and a screen moving direction.

In the embodiment of the present application, the user may move the screen to switch the presentation content in the video content. In the process of determining to switch the presentation content, first, the moving direction of the screen needs to be determined, for example, by moving the gyroscope built in the playback terminal. The direction of acceleration determines the direction of movement of the screen, and when determining the magnitude of the magnitude of the movement, it can be determined based on the magnitude of the acceleration. Secondly, the un-presented content corresponding to the moving direction of the screen needs to be determined, and the determining may be performed according to the corresponding relationship between the un-presented content and the moving direction of the screen, and after determining the un-presented content corresponding to the moving direction of the screen, the The presentation content is switched to the unpresented content corresponding to the screen moving direction.
