The following describes in detail a video playing method, an apparatus, a device, and a storage medium provided by the embodiments of the present disclosure with specific embodiments in conjunction with the accompanying drawings.

FIG. 1 illustrates a schematic diagram of anexemplary operating environment 100 in which embodiments of the present disclosure can be implemented, as shown in FIG. 1, in whichoperating environment 100 can include an electronic device 110 and a viewing user.

The electronic device 110 may be a mobile electronic device or a non-mobile electronic device. For example, the Mobile electronic device may be a notebook Computer, a palm Computer, an Ultra-Mobile Personal Computer (UMPC), or the like, and the non-Mobile electronic device may be a Personal Computer (PC), a television, or the like.

As an example, the electronic device 110 may obtain, in real time, a viewing angle of the viewing user, that is, an observation angle of the viewing user relative to a display screen of the electronic device, and determine and play a light field video corresponding to the viewing angle among a plurality of light field videos selected by the viewing user according to the viewing angle. The plurality of light field videos are videos of the same shooting scene shot by the light field shooting device. Alternatively, the plurality of light field videos may be videos stored by the electronic device 110, or videos stored in a video server, which is not limited herein.

In this way, the light field video corresponding to the viewing angle can be played through the viewing angle of the viewing user acquired in real time, so that the user can view the video content conforming to the current viewing angle when the viewing angle changes, and the immersive viewing experience is brought to the viewing user.

The following describes in detail a video playing method provided by an embodiment of the present disclosure, wherein an execution subject of the video playing method may be the electronic device 110 shown in fig. 1.

Fig. 2 shows a flowchart of avideo playing method 200 provided by an embodiment of the present disclosure, and as shown in fig. 2, thevideo playing method 200 may include the following steps:

s210, acquiring the viewing angle of the viewing user in real time.

In some embodiments, the eye position and the viewing direction of the viewing user may be obtained in real time, wherein the viewing direction may be a direction pointing from the pupil in the eye to the display screen on which the light field video is played. Illustratively, the eye position of the user and the direction of the pupil pointing to the display screen playing the light field video can be accurately acquired in real time through a camera, such as a depth camera, so that the acquisition accuracy of the eye position and the viewing direction can be improved. Optionally, the camera may be built in the electronic device, or may be externally connected through an interface, which is not limited herein.

Then, according to the eye position and the viewing direction, the viewing angle of the viewing user is determined. Illustratively, the eye position and the viewing direction may be calculated by a viewing angle calculation algorithm, resulting in a viewing angle. In this way, the viewing angle of the viewing user can be quickly determined based on the eye position and the viewing direction that are convenient to acquire.

And S220, determining the light field video corresponding to the viewing angle in the plurality of light field videos selected by the viewing user according to the viewing angle.

The multiple light field videos are videos shot by the light field shooting device in the same shooting scene, for example, videos of different light field parameters shot by a light field camera, that is, an insect eye camera, in the same shooting scene, and the light field parameters may include a light field angle and a light field focus.

Alternatively, the plurality of light field videos may be videos stored by the electronic device, or videos stored in a video server, which is not limited herein. If the light field video is a video stored by the electronic device, the light field video corresponding to the viewing angle in the plurality of light field videos selected by the viewing user can be directly determined by the electronic device. If the light field video is a video stored by the video server, the viewing angle may be sent to the video server by the electronic device, so that the video server determines the light field video corresponding to the viewing angle in the plurality of light field videos selected by the viewing user.

In some embodiments, a viewing angle change difference, that is, a viewing angle change degree, between a current viewing angle and a previous viewing angle may be calculated, and if the viewing angle change difference is greater than a preset threshold, a light field video corresponding to the current viewing angle in a plurality of light field videos selected by a viewing user is determined according to the current viewing angle. For example, a light field video having a light field angle that coincides with the current viewing angle may be determined from among the plurality of light field videos as the light field video corresponding to the current viewing angle.

In this way, the light field video corresponding to the currently watched visual angle can be determined and played when the visual angle change degree is large, and frequent switching of the light field video is avoided when the visual angle change degree is small, so that the watching flexibility of a user can be improved, and the energy consumption of equipment can be reduced.

And S230, playing the light field video corresponding to the viewing angle.

Optionally, if the light field video is a video stored by the electronic device, the light field video corresponding to the viewing angle may be directly played by the electronic device. If the light field video is the video stored by the video server, the electronic device can receive and play the picture of the light field video corresponding to the viewing angle sent by the video server.

In some embodiments, the light field video corresponding to the current viewing angle may be played based on the playing progress of the light field video played last, that is, the light field video corresponding to the current viewing angle may be played from the playing progress of the light field video played last, so as to improve the smoothness of video playing.

According to the embodiment of the disclosure, the viewing angle of the viewing user can be acquired in real time, and the light field video corresponding to the viewing angle in the plurality of light field videos selected by the viewing user is determined according to the viewing angle. Therefore, the light field video corresponding to the watching visual angle can be played through the watching visual angle of the watching user acquired in real time, so that the user can watch the video content conforming to the current visual angle when the watching visual angle changes, and immersive watching experience is brought to the watching user.

In some embodiments, a viewing angle variation trend of the viewing user may also be acquired, and the light field video corresponding to the expected viewing angle is preloaded according to the viewing angle variation trend. The viewing angle variation trend is used for predicting the viewing angle variation of the viewing user after a certain time length, and the expected viewing angle represents the viewing angle after a certain time length in the future. Therefore, the light field video corresponding to the expected viewing angle can be loaded in advance through the viewing angle variation trend, and the light field video can be switched smoothly.

As an example, linear fitting may be performed on a plurality of viewing angles of the viewing user acquired in real time to obtain a viewing angle variation trend of the viewing user, an expected viewing angle of the viewing user after the predicted duration is determined according to the viewing angle variation trend, and a light field video corresponding to the expected viewing angle is preloaded. That is to say, linear fitting can be performed through the acquired viewing angles, the variation trend of the viewing angles is determined rapidly and accurately, the expected viewing angles of the viewing users after the predicted duration are predicted based on the variation trend, and the light field videos corresponding to the expected viewing angles are loaded in advance, so that the light field videos can be switched smoothly in the follow-up process.

In some embodiments, the light field video may include a plurality of video segments, and the light field video corresponding to the surrounding viewing angle of the viewing angle may also be determined, and the video segments of the playing period after the current playing progress and the current playing progress in the light field video corresponding to the surrounding viewing angle are preloaded, so that the video segments of the playing period after the current playing progress and the current playing progress in the light field video corresponding to the viewing angle of the surrounding viewing angle may be preloaded in advance, which facilitates subsequent smooth switching from the video segment to the light field video segment corresponding to the real-time viewing angle, and improves video playing smoothness.

Specifically, if the light field video is a video stored in the electronic device, the electronic device may directly determine the light field video corresponding to the surrounding viewing angle, and preload a video segment in which the playing period includes the current playing progress and is after the current playing progress in the light field video corresponding to the surrounding viewing angle. If the light field video is the video stored by the video server, the electronic device can send the surrounding viewing angle to the video server, the video server determines the light field video corresponding to the surrounding viewing angle, and sends the light field video corresponding to the surrounding viewing angle, wherein the playing time interval comprises the current playing progress and a plurality of video segments of the playing time interval behind the current playing progress, so that the video preloading is realized on the basis of network bandwidth support, and the video playing is smoother.

In some embodiments, the viewing focus of the viewing user may also be obtained in real time, and the light field video corresponding to the viewing angle and the viewing focus in the plurality of light field videos selected by the viewing user is determined according to the viewing angle and the viewing focus, that is, the light field video with the light field angle and the light field focus consistent with the current viewing angle and the current viewing focus is determined as the light field video corresponding to the viewing angle and the viewing focus, and then the light field video is played.

For example, a viewing user is watching a person in a video, and then the viewing angle of the viewing user is not changed, but the viewing focus is shifted to a potted plant behind the person, and a light field video with the potted plant as the focus is played.

In this way, the light field video corresponding to the viewing angle and the viewing focus can be played through the viewing angle and the viewing focus of the viewing user acquired in real time, so that the user can view the video content conforming to the current viewing angle and/or the current focus when the viewing angle and/or the viewing focus are changed, and immersive viewing experience is brought to the viewing user.

The following may describe thevideo playing method 200 provided in the embodiment of the present disclosure in detail with reference to a specific embodiment, which is as follows:

the eye position and the watching direction of the watching user can be acquired in real time through the depth camera, and the watching visual angle of the watching user is determined according to the eye position and the watching direction.

And then, calculating the view angle change difference between the current view angle and the last view angle, and if the view angle change difference is larger than a preset threshold value, determining the light field video with the light field angle consistent with the current view angle from the plurality of light field videos selected by the user as the light field video corresponding to the current view angle.

And then playing the light field video corresponding to the current viewing angle based on the playing progress of the last played light field video. Before that, linear fitting can be performed on a plurality of viewing angles of the viewing user acquired in real time to obtain a viewing angle change trend of the viewing user, an expected viewing angle of the viewing user after the duration is predicted is determined according to the viewing angle change trend, and a light field video corresponding to the expected viewing angle is preloaded.
