When the video window is displayed, the number of people watching the video window, the heat and the like can be displayed for the user to refer to. Of course, the foregoing is merely illustrative and is not intended to be a limitation of the present application.
In the embodiment of the present application, the video data of the viewing perspective may be, for example: video data corresponding to the viewing angle of the stage being faced, video data corresponding to the viewing angle of the stage being overlooked, and the like; the video data corresponding to the tracked subject may be video data corresponding to a certain athlete, actor, or the like.

Of course, the foregoing is merely illustrative and is not intended to be a limitation of the present application.
For example, in this embodiment, the presenting a plurality of candidate video windows in a video playing interface includes: according to the received recommendation information, a plurality of candidate video windows are determined from a plurality of preset video windows, and the candidate video windows are displayed in a video playing interface. Therefore, the displayed candidate video windows can be more suitable for the requirements of the user.
The client side can comprise a plurality of pieces of preset video window information, and after receiving the recommendation information, the client side can determine a relatively popular viewing angle or track the main body from the recommendation information, so that candidate video windows can be determined from the preset video windows according to the recommendation information and displayed, and the candidate video windows displayed to the user can better meet the requirements of the user.
Further, in this embodiment, the client may establish a video window first, and after receiving the recommendation information, determine viewing angle information or tracking subject information corresponding to the video window according to the recommendation information.
S302, determining a video switching instruction according to the video window corresponding to the received selection operation, wherein the video switching instruction comprises the selected viewing angle information or the tracking subject information.
In this embodiment, after the video window is displayed in the video playing interface, a user can enter and exit the selection operation by clicking a screen or the like, so that the client can determine the corresponding video window according to the received selection operation.
Since the plurality of video windows correspond to the viewing angle information or the tracking subject information, when the video window corresponding to the selection operation of the user is determined, the video switching instruction can be determined directly according to the viewing angle information or the tracking subject information corresponding to the video window.
Specifically, the video switching instruction may directly include viewing perspective information or tracking subject information of the selected video window; or the video switching instruction may directly include the ID value of the video window, so that the viewing angle information or the tracking subject information corresponding to the ID value may be determined according to the ID value of the video window, which is not limited in this embodiment.

After receiving the video switching instruction, the server may determine first video data corresponding to the video switching instruction and return the first video data to the client.
S304, receiving the first video data returned in response to the video switching instruction.
For example, in this embodiment, before receiving the first video data returned in response to the video switching instruction, the method further includes: amplifying the selected video window according to the selection operation; the playing the first video data indicated by the video switching instruction includes: and playing the first video data corresponding to the video switching instruction in the amplified video window so as to achieve a better playing effect and provide user experience.
In this embodiment, a plurality of candidate video windows are displayed on the video playing interface, after it is determined that a user selects a certain candidate video window, the selected video window may be enlarged, and other video windows except the selected candidate video window may be reduced or slid out of the video playing interface. After receiving the first video data indicated by the video switching instruction, the first video data can be played in an enlarged video window so that the user can watch the first video data selected by the user.
S305, playing the first video data indicated by the video switching instruction.
For example, in this embodiment, step S305 may include: determining type information of the first video data according to the video switching instruction, wherein the type information comprises an augmented reality video type or a virtual reality video type; performing corresponding augmented reality processing or virtual reality processing on the first video data according to the determined type information, and obtaining processed first video data; and playing the processed first video data. Therefore, the type information can be determined according to the video switching instruction, and the virtual reality or augmented reality display is carried out, so that the user experience is improved.
For example, in this embodiment, the type information may be directly determined according to the client of the user, for example, if the client of the user is a virtual reality device, the default type information is a virtual reality video type; and if the client of the user is the augmented reality equipment, the default type information is the augmented reality type information.
If the type information is a virtual reality type, the first video data can be subjected to virtual reality processing and played through virtual reality equipment of the user. For example, when a user watches live broadcasting at home, the first video data is processed in a virtual reality mode and played, so that the user has a feeling of being personally on the scene in the watching process, and the participation degree of the user is improved. In addition, if the user watches through the virtual reality device, the video switching information can be directly generated according to the movement data of the user.
For example, when watching a live broadcast, a user can directly display the live broadcast to the user through the virtual reality device, and can display first video data corresponding to a watching angle according to a video switching instruction of the user, so that the user can feel the effect of directly watching the live broadcast at the watching angle; alternatively, the first video data of the tracking subject may be presented at a video switching instruction of the user, so that the user produces an effect of moving along with the tracking subject.
If the type information is the augmented reality type, the augmented reality video and the scene where the user is located can be combined for display, for example, if the user watches a match, the corresponding video can be directly superimposed on the desktop of the scene where the user is located through the augmented reality device for display. By carrying out augmented reality processing, the content richness of images in the video watched by the user can be improved, and further the user experience is improved.
It should be noted that the virtual reality processing procedure and the augmented reality processing procedure may be executed at a server or by a client, which is not limited in this embodiment. For a specific method for performing virtual reality processing or augmented reality processing, reference may be made to related technologies, which are not described herein again.
For example, in this embodiment, the receiving the first video data returned in response to the video switching instruction includes: and receiving first video data returned in response to the video switching instruction in the video live broadcasting process. Therefore, the user can conveniently watch the live broadcast.
The following provides an exemplary description of the solution of the present application through a specific application scenario.
As shown in fig. 3B, a stage (i.e., a target area) is shown, on which a plurality of image capturing devices at different positions are arranged, so that the image capturing is performed on the stage at a plurality of positions, and a plurality of second video data is obtained.
The second video data may be transmitted to the server, thereby determining the first video data from the plurality of second video data. For example, an actor a may be included on the stage, and when moving from one end of the stage to the other end of the stage, first video data for tracking the actor a may be obtained by splicing a plurality of second video data; alternatively, the video data captured by the image capturing device directly facing the middle of the stage may be used as the first video data having the set viewing angle.
When a user watches through the client, as shown in fig. 3C, a squared figure composed of video windows is displayed in the video playing interface, each video window corresponds to a first video data, and a thumbnail of the first video data and the like can be displayed in the video window. The first video data may include first video data corresponding to respective viewing perspectives, or first video data corresponding to actors a, B, C, etc. (tracking subjects), may further include first video data corresponding to a stage panorama, and the like.
The user can select the corresponding first video data by triggering the video window of the video playing interface, and the client can generate and send a video switching instruction according to the selection operation of the user so as to receive the first video data responding to the video switching instruction.
While the first video data is received, after the user inputs a selection operation, the video window selected by the user may be displayed in an enlarged manner, and other windows except the selected video window may be reduced to the edge of the interface, for example, as shown in fig. 3D. Of course, other windows than the selected video window may also be destroyed directly and not displayed.
For example, if the user selects the first video data corresponding to the actor a, that is, the first video data generated by using the actor a as the tracking subject, and if the actor a moves from one end of the stage to the other end, the generated first video data is the first video data obtained by splicing segments of the plurality of second video data including the actor a in a time sequence or a position sequence.
Through the scheme provided by the embodiment, the plurality of video windows can be displayed to the user in advance, and the first video data corresponding to the selected video window is played according to the selection of the user, so that the user can operate conveniently, and the user experience is further improved.
The video playing method of the present embodiment may be executed by any suitable electronic device with data processing capability, including but not limited to: server, mobile terminal (such as mobile phone, PAD, etc.), PC, etc.
Example four
Referring to fig. 4, which shows a schematic flow chart of a video playing method of the present application, the scheme provided in this embodiment is applied to a server, and as shown in the figure, the scheme includes:
s401, receiving a plurality of second video data, wherein the second video data are a plurality of video data obtained by image acquisition of a target area by image acquisition equipment at a plurality of positions.
For example, in any embodiment of the present application, the image capturing devices at multiple positions may be: the tracking system comprises image acquisition equipment at different angles relative to a target area, image acquisition equipment at different distances relative to the target area, image acquisition equipment for performing image acquisition along with a tracking subject and the like.
The different angles relative to the target area can be that the included angle between the central axis of the target area and the target area is 30 degrees, and the like. Of course, the foregoing is merely illustrative and is not intended to be a limitation of the present application.
The image acquisition equipment at different angles relative to the target area acquires images, and second video data at different watching angles can be obtained, so that the integrity of the second video data can be ensured, for example, the second video data can be ensured to cover the whole stage as much as possible.
The image capturing devices at different distances with respect to the target area may be an image capturing device for a long shot, an image capturing device for a panoramic view, an image capturing device for a medium shot, an image capturing device for a close shot, or an image capturing device for close-up, etc. By collecting images according to different distances, second video data under different distances can be obtained, and the content played by the user can be richer.
The image acquisition following the tracked subject may be: the image acquisition equipment and the tracking main body move synchronously to carry out dynamic tracking, therefore, hot spot characters and the like can be shot with the whole course, and the obtained second video data can better meet the requirements of users.
In addition, if the position, the angle and the like of the image acquisition device can be adjusted, the video switching instruction may further include acquisition parameters, such as a viewing angle, a viewing distance and the like, and the position and the like of the image acquisition device may be adjusted according to the acquisition parameters, and the adjusted image acquisition device is acquired to acquire an image, so as to obtain second video data meeting the user requirement, and generate first video data meeting the user requirement.
S402, determining a plurality of first video data with different viewing angles or different tracking subjects according to the plurality of second video data.
For example, in an implementation of the present application, a plurality of second video data collected at the same position and using the same viewing angle may be combined in a time sequence, and first video data corresponding to the viewing angle may be obtained.
Specifically, the image capturing apparatus may capture and upload a video clip (second video data) of 30s at a time, and thereby, the plurality of video clips uploaded by the image capturing apparatus may be temporally combined to obtain the first video data having the viewing angle.
For example, the first video data with different viewing angles may be specifically first video data obtained by splicing second video data acquired at multiple viewing angles. For example, the second video data acquired by the image acquisition device a and the second video data acquired by the image acquisition device B may be spliced to obtain the first video data corresponding to the larger viewing angle; or, if the character a and the character B are interacting, the second video data including the two characters may be spliced to obtain the first video data, so that the user can see the two interacting characters through a picture corresponding to the first video data.
The second video data acquired by the image acquisition devices at different distances relative to the target area may be synthesized based on the acquisition distances to obtain the first video data. For example, depth-of-field synthesis can be performed on second video data acquired by image acquisition devices at different distances to obtain first video data, so as to improve video definition corresponding to the first video data; alternatively, the second video data acquired by the image acquisition devices at different distances are directly overlapped to generate the first video data, so that a plurality of overlapped sub-images can be included in one frame of image in the first video data, for example, the second video data close-up to a human face is overlapped on the second video data including the whole human body to obtain the first video data.
For example, in another implementation of the present application, a plurality of second video data including the same tracking subject are combined according to a relative positional relationship between positions of image acquisition and a time sequence, and first video data corresponding to the tracking subject is obtained.
For example, the plurality of first video data of different tracked subjects may be video data obtained by synthesizing video segments including the target subject in a time order and a relative positional relationship between positions of image acquisition. For example, a person a moves from the left side of the stage to the right side of the stage, and six image capturing devices respectively capture images of the person a during the movement process, the second video data of the six image capturing devices may be processed, video segments including the person a are edited, and the video segments are spliced according to the relative position relationship and the time sequence between the image capturing positions, so as to obtain first video data corresponding to the movement process of the person a moving from the left side of the stage to the right side of the stage.
For example, in any embodiment of the present application, the video data may be processed by using a big data computing capability to obtain at least one piece of video data.
Specifically, the video data may be subjected to face recognition or article recognition through the big data computing power, and the video data is processed according to the recognition result, for example, a part of the video data including the same person or the same article is combined into one video data, or video data corresponding to adjacent viewing perspectives are combined to obtain video data corresponding to a larger viewing perspective. The video data is processed by large data computing capacity, so that the speed of obtaining the video data can be improved, and the capacity requirement on broadcasting guidance and the like can be reduced.
In addition, the first video data may be merged by means of depth map reconstruction, for example, for the second video data acquired by the two image acquisition devices, a depth image corresponding to the second video data may be obtained, where the depth image is also called a range image, and is an image that reflects the distance from the image acquisition device to each point of the target region and serves as a pixel value, and the depth image may directly reflect the geometric shape of the surface included in the target region. The image transformation matrixes corresponding to the second video data can be determined through the depth images corresponding to the different second video data, and the second video images are transformed through the image transformation matrixes, so that the same geometric shapes included in the second video images can be directly overlapped, and the second video images can be combined.

In this embodiment, the first video data may be sent to a client corresponding to the video switching instruction, and played by the client to be displayed to the user.
For example, in any embodiment of the present application, step S403 includes: according to the watching visual angle information or tracking subject information carried in the video switching instruction, determining first video data matched with the watching visual angle information or first video data matched with the tracking subject information from the plurality of first video data; and transmitting the determined first video data.
In this embodiment, after the client receives a video switching instruction of a user, the video switching instruction may be sent to the processing device, and the processing device may query, according to the received video switching instruction, first video data corresponding to the video switching instruction from the plurality of first video data, specifically, may query, according to viewing angle information or tracking subject information included in the video switching instruction, the matched first video data, and send the queried first video data to the client.
In addition, in this embodiment, the server may perform virtual reality processing or augmented reality processing on the first video data obtained by querying according to the video switching instruction, and then send the first video data to the client, so that the client plays the first video data after the virtual reality processing or augmented reality processing.
