In some embodiments, as shown in fig. 5, the navigation bar may be provided with a plurality of controls, such as "my", "channel", "movie", "fitness", "VIP", "education", "mall", "game", and application, different navigation bar controls correspond to different channel interfaces, if the user wants to perform fitness, the "fitness" control may be selected, the interface shown in fig. 5 is the interface after the "fitness" control is selected, and the user may select a fitness video on the interface to perform fitness following the fitness video.
Referring to fig. 6, after the user clicks one fitness video on the interface shown in fig. 5, the display device requests the server to issue corresponding detail page data according to the configuration parameters corresponding to the selected video control, and then enters the media resource detail interface shown in fig. 6 according to the received detail page data. As shown in fig. 6, the media resource detail interface may display a plurality of course bar controls of the fitness video, or may not include the course bar controls, and after the user clicks one of the course bar controls or starts training, the display device acquires the fitness video corresponding to the course bar control/detail page, and then enters the play mode selection interface. In the following description, the played fitness video is also referred to as a target video.
Referring to fig. 7, the play mode selection interface may show three mode controls, where a play mode corresponding to a first mode control is a normal mode, which may also be referred to as a first mode, a play mode corresponding to a second mode control is a follow-through mode, which may also be referred to as a second mode, and a play mode corresponding to a third mode control is a view mode, which may also be referred to as a third mode. Each mode control can display an explanation of the play mode, and for example, the explanation of the normal mode can be: "the whole teaching video is watched by shielding the camera to be familiar with the training action", the explanation of the following training mode can be: "turn on the lens to obtain the real-time comparison of the movement and make the movement more standard", the explanation of the film viewing mode can be: the exercise effect is not folded when the camera is shielded and the user looks at the camera.
As can be seen from the above explanation, in some embodiments, in the normal mode, the display device does not start the camera, and only sets one playing window on a new interface to play the fitness video, in the follow-up exercise mode, the display device starts the camera, and sets two playing windows on a new interface of the display to simultaneously play the image collected by the camera and the fitness video, respectively, in the movie watching mode, the display device does not start the camera, and sets two playing windows on a new interface of the display to simultaneously play the fitness video and a movie, respectively.
In some embodiments, the display device may be provided with a camera, the camera may include a lifting camera or a non-lifting camera, the camera may capture an image of the user to obtain local camera data, and the controller of the display device may display the local camera data captured by the camera on a display of the display device, so that the user can see his/her own actions on the display.
In some embodiments, the display device is not provided with a camera, but may be connected with a camera, for example, an external camera connected via USB, and the camera is used to capture images of a user, and the controller of the display device may display local data captured by the camera on the display of the display device.
The user can select a play mode to watch the fitness video according to the explanation.
In some embodiments, if the user clicks the common mode control on the play mode selection interface shown in fig. 7, the display device generates a media asset play instruction, where the media asset play instruction includes information of a play mode and a target video, and at this time, the play mode is the common mode, and the information of the target video includes a play address of the target video. And the display equipment acquires the video data stream of the target video from the playing address of the target video according to the media asset playing instruction, and generates a first playing window for playing the target video on a new interface according to the fact that the playing mode is a common mode. In some embodiments, the first playback window may be a full screen window with a display ratio of 16: 9.
In some embodiments, the proportion of the fitness video corresponds to the proportion of a full-screen window, since the proportion of the fitness video is typically 16:9, and the proportion of a full-screen window is also 16: 9. In the normal mode, the display device only generates one first playing window, does not generate other windows, and does not shield the display content of the first playing window by other windows, so that the display device can directly play the fitness video in the first playing window in a full screen mode according to the fact that the playing mode of the media asset playing instruction is the normal mode after the first playing window is generated.
In some embodiments, to implement full-screen playing of the fitness video in the first playing window, the display device may scale the image of the target video to make the image size of the scaled target video consistent with the size of the full-screen window.
In some embodiments, the method for the display device to zoom the target video may be: analyzing a video data stream of a target video to obtain a video frame sequence of the target video, taking a first frame image in the video frame sequence, obtaining a scaling ratio according to the ratio of the image height to the height of the target display area, and then scaling the video frame sequence of the target video according to the scaling ratio. Illustratively, the image height of the target video is 100, and the height of the full-screen window of the display device is 1000, where the height may be the number of pixel points in the vertical direction, and then the scaling ratio is: when the video frame sequence of the target video is enlarged by 10 times according to the scaling ratio, the enlarged image of the target video can fill the whole full-screen window.
In some embodiments, the display device scales the target video to obtain a video frame sequence of the scaled target video, and sends the video frame sequence to the first play window, so that the first play window can continuously play the video frame sequence.
Referring to fig. 8, which is a schematic diagram of a full screen playing interface in a normal playing mode according to some embodiments, as shown in fig. 8, in the normal playing mode, a target video may be played in a full screen, a character in fig. 8 may be a fitness trainer, and a line may represent a background of the character, where in an image of the target video, the character is displayed in the middle, and both the left side and the right side behind the character are background images.
In some embodiments, if the user clicks the follow-up mode control on the play mode selection interface shown in fig. 7, the display device generates a media asset play instruction, where the media asset play instruction includes information of a play mode and a target video, and at this time, the play mode is the follow-up mode, and the information of the target video includes a play address of the target video. And the display equipment acquires the video data stream of the target video from the playing address of the target video according to the media asset playing instruction, and generates a first playing window for playing the target video and a second playing window for playing the local camera data on a new interface according to the fact that the playing mode is the follow-training mode.
In some embodiments, a second playback window is superimposed over the first playback window.
In some embodiments, the second playback window is at the same height as the first playback window, and the left boundary of the second playback window coincides with the left boundary of the first playback window, or the right boundary of the second playback window coincides with the right boundary of the first playback window.
In some embodiments, the location of the window may be achieved by setting a coordinate parameter of the window in the interface.
In some embodiments, referring to fig. 9, in the follow-up mode, the first playing window may be a full-screen window with a display ratio of 16:9, and the second playing window may be a window higher than the display, and the display ratio may be determined according to the shooting parameters of the camera. The second playing window may be displayed on one side of the first playing window in a form of a map in an overlapping manner, for example, the second playing window may be displayed on the right side of the first playing window and coincide with the right side edge of the first playing window, so as to shield the right side display area of the first playing window. If the display device zooms the target video to the size same as that of the full-screen window, and then directly displays the zoomed image in the full-screen window, due to the sheltering of the second playing window, if partial image of the target video cannot be watched by the user according to the normal window display logic, the user can only watch the image which is not sheltered by the second playing window in the target video. When the target video is the fitness video, the user needs to move along with the movement of the fitness coach in the fitness video, the fitness coach is a person in the target video and is usually located in the middle of an image of the fitness video, and the second playing window may block part of the body of the fitness coach, so that the watching effect of the fitness video is influenced.
In some embodiments, to reduce the probability that the body of the fitness trainer is blocked, the display device may determine, in the follow-up mode, a target display area in the first play window, where the target display area is an area that is not blocked by the second play window, and the display device may display an image of the target video offset to the left in the target display area, so that the user can see a more complete fitness activity in the target display area.
In some embodiments, the target display area is determined according to the position coordinates of the first playing window and the position coordinates of the second playing window. The position coordinates of the target display area can be obtained by subtracting the position coordinates of the second play window from the position coordinates of the first play window.
It should be noted that the target display area refers to a preferred display area in the first playing window, content displayed in the target display area is not blocked by other images, in the follow-up mode, the display device has a second playing window in addition to the first playing window, and the second playing window partially blocks the first playing window, so that the display device can determine an area, which is located on the left side of the second playing window in the first playing window and is not blocked by the second playing window, as the target display area. Referring to fig. 10, the second playing window is displayed above and superposed on the right side of the first playing window, and an area on the left side of the first playing window that is not covered by the second playing window may be determined as a target display area of the first playing window.
It should be noted that, in the follow-up mode, the first play window is blocked by the second play window, and the display device determines the target display area according to the position of the second play window on the first play window. In some video playing scenes, the first playing window for playing the video may not be blocked by the second playing window for playing the local data of the camera, but may be blocked by other images, for example, a non-transparent control for displaying a picture. At this time, if the position of the control for shielding the first playing window is the same as the position of the second playing window for shielding the first playing window, namely, the control is shielded on one side of the first playing window, and one width side of the control is overlapped with one width side of the first playing window, the target display area can be determined as a rectangular area which is not shielded by the control in the first playing window. If all edges of the control are not overlapped with the first playing window, no matter which side of the control the target display area is arranged on, the size of the target display area is smaller, so that all the display areas of the first playing window can be determined as the target display area, namely, the target video is played in the first playing window in a full screen mode.
In some embodiments, in the follow-up mode, since the target display area is only a partial display area of the first playing window, the size ratio of the target display area may not be 16:9, and to obtain a better playing effect, the target video may be scaled first, and then the image of the scaled target video may be shifted to the left, so that the center line of the shifted image is close to the center line of the target display area, or the center line of the shifted image is overlapped with the center line of the target display area, so that the user may see a more complete image of the person in the target display area.
In some embodiments, in the software execution process, the target display area may not be determined, and the first moving distance of the target video may be directly determined according to the position parameters of the first playing window and the second playing window in the playing interface. An exemplary target video is zoomed during playing of a player, in order to ensure that display content is not deformed, images are generally scaled in a height direction and a width direction in an equal proportion, a general scaling rule is to scale the images after confirming scaling factors according to the height (width), the zoomed images fill the height (width) of a playing window in the height (width), and black insertion can be performed in the other dimension. The height direction may be used as a reference, and the width direction may be used as a reference. And determining a first distance that the image of the target video needs to move in the display process according to the width parameter of the first player and the width parameter of the second player. So that the intermediate position of the target video image frame is displayed in the unobstructed area of the first video window as much as possible.
Referring to fig. 11, after the image of the target video is shifted to the left by the first movement distance D, it can be seen that the image of the person in the target video is closer to the left side of the screen than before the shift.
Referring to fig. 12, after the image of the target video is shifted to the left by the first moving distance D, the background image on the right side of the character in the target video can be shielded through the second playing window, and at this time, the second playing window does not shield the character in the first playing window, so that a good display effect is achieved.
In order to calculate the first moving distance D, in some embodiments, the image of the target video may be scaled to obtain an image width of the target video after being scaled to the size of the first playing window, where the image width may be referred to as a width to be displayed; then obtaining the width of a second playing window; the two widths are differentiated to obtain the width of the target display area; and taking a half of the difference between the width to be displayed and the width of the target display area as a first moving distance. According to the calculation method, the first moving distance D of the left offset of the target video is the same as the distance of the right side of the target video, which is shielded by the second playing window, so that the center line of the target video is superposed with the center line of the target display area. The calculation method can be called as an averaging method, has the advantages of simple calculation and high calculation speed, and can quickly determine the size of the first moving distance D.
In some embodiments, the first movement distance may be any distance less than the difference in the widths of the two playing windows.
In some embodiments, the first movement distance is not greater than the width of the second playback window.
In some embodiments, the first moving distance may be determined directly according to the width of the second playing window, and for example, half of the width of the second playing window is taken as the distance to be moved, and the first moving distance is not greater than the distance to be moved.
In some embodiments, the first moving distance may be obtained by taking a difference between the width of the scaled movie and the width of the second playing window, for example, half of the difference may be used as the first moving distance.
In some embodiments, the determination of the first movement distance is made according to a position parameter of the playing window.
In some embodiments, the fitness trainer in the target video may not be located in the middle of the image, and at this time, if a method of setting the first moving distance D offset on the left side of the target video to be the same as the distance at which the right side of the target video is blocked by the second playing window is adopted, the fitness trainer in the target video may be deviated to the left or right, and the display effect is poor. For example, human body recognition can be performed on the image frames of the target video, and after the human body is recognized, namely the fitness trainer, symmetrically extending along the central axis of the human body to two sides until the width of the display area containing the human body is the same as that of the target display area, at this time, taking the difference value between the width starting point of the display area containing the human body and the width starting point of the first playing window as a first moving distance, the first moving distance obtained by the calculation method may be different from the first moving distance obtained by the averaging method, and if the fitness coach is on the left in the media image of the target video, if the first moving distance obtained by the calculation method is smaller than the first moving distance obtained by the average method, if the fitness coach inclines to the right in the media asset image of the target video, the first movement distance obtained by the calculation method is larger than the first movement distance obtained by the averaging method.
After obtaining the first movement distance D, in some embodiments, the display device may implement image offset display of the target video by dynamically setting presentation of the surfaceView. The offset output function for surfaceView may be: layout param. setmarsins (0-D,0,0, 0). As shown in fig. 12, the offset output function indicates that the left offset amount is D, so that the left starting point of the asset image is (0-D), the left starting point of the asset image in the first playing window is 0, and since the first playing window needs to display the image from the position of the starting point of 0 when displaying the image. Therefore, according to the above-mentioned offset output function, when the first playing window shows each frame of image of the target video, the media resource images are displayed in the first playing window from the pixel points of the target video on the right side of the first moving distance D, the images in the first moving distance D exceed the display range of the first playing window, the partial images cannot be displayed in the first playing window, the display effect of displaying the images of the target video in a leftward offset manner is realized, on the right side of the image of the target video, the first playing window still has a part of the display area which can display black edges, and by placing the second playing window on the top for display, the second playing window can cover part of the background image on the right side of the character in the image of the target video and the black edge, so that the user can not see the part of the background image and the black edge, and the watching experience of the user is not influenced. The second playing window may be set to top by setting setzorderontop (true).
According to the method for dynamically setting surfaceView, the playing interface of the display device in the follow-up mode is as shown in FIG. 13, the middle image of the target video is displayed in the target display area of the first playing window, and the user image is displayed in the second playing window.
In some embodiments, after receiving a target video, a display device decodes the target video, performs scaling according to a parameter of a first playing window, and then displays a position parameter of an image frame after moving the image frame leftwards by a first distance in an image frame display process.
In some embodiments, the second playing window plays the acquired video data of the camera.
It can be seen from the above embodiments that, in the embodiments of the present application, a display area where the target video is not blocked is detected on the display device, and the display area is determined as the target display area, and then after the target video is zoomed, the image of the target video is controlled to perform offset display in the target display area, so that a problem of a poor display effect caused by the fact that the target video is blocked by the second play window during playing in the follow-up mode is solved, and the viewing experience of a user is improved.
