[0025] The following will be combined with the drawings in this application to clearly and completely describe the technical solutions in this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0026] It should be noted that, in this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in this application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0027] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0028] In the description of this application, unless otherwise specified, " / " means "or", for example, A / B can mean A or B. "And / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, "at least one" means one or more, and "multiple" means two or more.

[0029] Based on the video live broadcast method described in the background technology, in the current live broadcast, users can only passively watch the video images with fixed perspectives or contents played by the live broadcast personnel. The perspectives or contents of this method are relatively single, and the user experience is poor.

[0030] Based on this, an embodiment of the present application proposes a method for playing a video screen, in which the target video stream played in the terminal (i.e., the first terminal) has at least two video screens. After receiving an operation to switch the target video stream from the first video screen to the second video screen, the terminal sends a video screen switching request to the computing device, and the computing device switches the target video stream in the terminal from the first video screen to the second video screen based on the request. It can be understood that the target video stream includes at least two video screens of the service, and the user can control the screen switching through the first terminal, that is, the control of the video screen is switched from the second terminal to the first terminal, which can improve the user experience.

[0031] The implementation of the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0032] Please refer to Figure 1 , which shows an implementation environment involved in a method for playing a video image provided in an embodiment of the present application, the implementation environment includes: a computing device 110 and a first terminal 120, and optionally also includes: a camera 130 and a second terminal 140.

[0033] The computing device 110 is a device with a video data processing function. In the embodiment of the present application, the computing device 110 is used to process data such as video information, audio information, and generate video, and send the target video stream to the first terminal 120 through a content delivery network (CDN). The process of the first terminal 120 obtaining the target video stream from the computing device 110 can be called stream pulling. In the present application, the computing device 110 is the execution subject of the video screen playback method.

[0034] CDN is a distributed content distribution network built on a data network. CDN mainly includes: source station, cache server, domain name system (DNS) and client and other components. In the embodiment of the present application, the computing device 110 is applied to CDN, which is equivalent to the source station in CDN.

[0035] Optionally, the functions implemented by the computing device 110 may be performed by one device or by multiple devices, and the present application does not limit the architecture of the computing device 110. It is understandable that the computing device 110 includes at least one device.

[0036] In one possible implementation, the computing device 110 includes an information encoding, decoding, transmission and operation management module, which is mainly used to encode the target video stream and align the video part and the audio part in the target video stream in time.

[0037] By way of example, the computing device 110 may be a computing device such as a server, a tablet computer, a desktop, a laptop, a notebook computer, or a netbook.

[0038] The first terminal 120 is a device for decoding the target video stream sent by the computing device 110 and playing the target video stream (eg, the target video stream). Optionally, the first terminal 120 has a hardware or software switch for turning on or off the video screen switching function.

[0039] Exemplarily, the first terminal 120 may be a device such as a mobile phone, a tablet computer, a desktop, a laptop, a notebook computer or a netbook.

[0040] Optionally, the first terminal 120 is integrated with a screen and an input module, or the first terminal 120 is connected to the screen and the input module respectively. The screen and the input module can be integrated devices, such as a touch screen. The screen and the input module can also be separately set devices, in which case the input module can be a device such as a keyboard or a mouse.

[0041] The camera 130 is used to capture videos, such as the target video stream in the embodiment of the present application. The camera 130 may be a special camera with a depth perception function, capable of capturing videos containing depth of field information and viewing angle information, and the video captured by this type of camera is a 3D video. The camera 130 may also be a device for capturing 2D videos from multiple viewing angles. In the embodiment of the present application, the camera 130 may send the captured target video to the computing device 110 via the second terminal 140. In another possible implementation method, the camera 130 is an intelligent camera with a networking function, which may directly send the captured target video to the computing device 110.

[0042] The above is a possible implementation method for collecting the target video stream. Optionally, the target video stream can also be videos of different perspectives shot by multiple ordinary cameras, which are then synthesized into the target video stream. The present application embodiment does not limit the device for collecting the target video stream and the collection method.

[0043] The second terminal 140 is a device with a data processing function. In the embodiment of the present application, the second terminal 140 can run a first application, and the first application includes, for example, an office application, a video application, or a game application. The second terminal 140 can record the application interface of the first application in real time to obtain a target video stream. At the same time, the second terminal 140 sends the generated target video stream to the computing device 110.

[0044] Exemplarily, the second terminal 140 may include computing devices such as a mobile phone, a server, a tablet computer, a desktop, a laptop, a notebook computer, and a netbook.

[0045] It is understandable that, in the embodiment of the present application, the target video stream processed by the computing device 110 may be a video stream of the first application recorded and sent by the second terminal 140 and a video stream containing an information stream provided by the first application, or a video stream collected by the camera 130 and sent to the computing device 110 via the second terminal 140, or a live video stream directly sent by the camera 130 to the computing device 110. The process of the camera 130 or the second terminal 140 sending the target video stream to the computing device 110 may be called streaming.

[0046] The computing device 110, the first terminal 120, and the second terminal 140 are all connected to Ethernet. Each device is connected to the network. Optionally, the camera 130 is connected to Ethernet and connected to the computing device 110 through the network, or the camera 130 is connected to the second terminal 140 by wire or wireless, or the camera 130 is integrated with the second terminal 140. The embodiment of the present application does not limit the number of computing devices 110, the first terminal 120, the camera 130, and the second terminal 140.

[0047] In a possible implementation, a server of a second application (e.g., video live broadcast software) is installed in the computing device 110, and a client of the second application is installed in both the second terminal 140 and the first terminal 120. The client of the second application in the second terminal 140 is used to send the acquired target video stream to the server in the computing device 110; after processing the target video stream, the server of the second application in the computing device 110 sends it to the client of the second application in the first terminal 120; the client of the second application in the first terminal 120 receives the target video stream sent by the computing device 110 and plays the target video stream. Optionally, the client of the second application in the first terminal 120 can also set a function switch for turning on or off the video screen of the target video.

[0048] In another possible implementation, a server of the second application is installed in the computing device 110, and a client of the second application is installed in each of the first terminals 120. After the camera 130 captures the target video stream, it sends it to the server of the second application in the computing device 110. After the server of the second application in the computing device 110 processes the target video stream, it sends the target video stream to the client of the second application in the first terminal 120. The client of the second application in the first terminal 120 receives the target video stream sent by the computing device 110 and plays the target video stream. Optionally, the client of the second application in the first terminal 120 can also set a function switch for turning on or off the video screen of the target video stream.

[0049] In an application scenario, after the camera 130 captures a target video stream containing multiple pictures, it sends it to the computing device 110. After the computing device 110 performs video and audio alignment processing on the target video stream, it sends the default video picture (i.e., the first video picture) of the target video stream to the first terminal 120. The first terminal 120 plays the default video picture of the target video stream. At the same time, the first terminal 120 also includes options for other video pictures (i.e., the second video picture). The user switches the default video picture to other video pictures in the first terminal 120. Based on the user's operation, the first terminal 120 sends a video picture playback request to the computing device 110. Based on the request of the first terminal 120, the computing device 110 switches the default video picture played by the first terminal 120 to the other video picture requested by the first terminal 120.

[0050] In another application scenario, the first application is a game application installed in the second terminal 140. The game application is operated in the second terminal 140, and the operation process is recorded to obtain the first video screen of the target video stream. The first video screen can be set as the default video screen. In addition, the second terminal 140 accesses the preset information stream of the game application to generate at least the second video screen of the second target video stream. The second terminal 140 sends the target video stream containing the second video screen of the first video screen to the computing device 110. After the computing device 110 performs video and audio alignment processing on the target video stream, it sends the first video screen of the target video stream to the first terminal 120. The first terminal 120 plays the first video screen of the target video stream, and at the same time, the first terminal 120 also includes at least the option of the second video screen. The user switches the first video screen to the second video screen in the first terminal 120. Based on the user's operation, the first terminal 120 sends a video screen playback request to the computing device 110. Based on the request of the first terminal 120, the computing device 110 switches the first video screen played by the first terminal 120 to the second video screen requested by the first terminal 120.

[0051] The following is a description of the video playback method provided in the embodiment of the present application:

[0052] The video playback method provided in the embodiment of the present application can be applied to the computing device 110. The execution subject of the video playback method provided in the embodiment of the present application can also be a video playback device. The video playback device can be a computing device, or a central processing unit (CPU) in the computing device, or a control module in the computing device for executing the video playback method. The following description is based on the method provided in the embodiment of the present application as a computing device.

[0053] Please refer to Figure 2 , is a flow chart of a method for playing a video screen provided in an embodiment of the present application. Figure 2 As shown, the method may include S101 - S110 .

[0054] S101: A computing device obtains a target video stream.

[0055] Video streaming is real-time transmission of video data. Devices can play videos online without downloading them. Video streaming can be used in video conferencing, interactive games, or live broadcast services.

[0056] The target video stream may be a common 2D video stream or a 3D video stream including depth information.

[0057] The target video stream includes at least two video pictures, and the at least two video pictures include a first video picture and a second video picture. Optionally, the first video picture is a preset video picture, and the preset video picture can be understood as a default video picture.

[0058] Optionally, the second terminal, or after the second terminal captures the target video stream through the camera, uses the real-time messaging protocol (RTMP) protocol, the adaptive bit rate streaming media transmission protocol (HTTP live streaming, HLS) based on the hypertext transfer protocol (HTTP), or the real-time streaming protocol (RTSP) to send the target video stream to the computing device.

[0059] The preset video screen can generally be set by the user on the device that collects the target video stream (for example Figure 1If the user does not specify a preset video screen, the preset video screen may also be a video screen randomly selected from multiple screens of the target video stream by the device that captures the target video stream, or a video screen randomly selected from multiple screens of the target video stream by the computing device as the preset video screen.

[0060] In a possible implementation, image frames of at least two video pictures in the target video stream have different marks, for example, image frames of the first video picture are marked as "1", and image frames of the second video picture are marked as "2".

[0061] In one possible scenario, the target video stream includes video images from at least two perspectives in a live broadcast; the first video image is a video image from the first perspective in the target video stream; and the second video image is a video image from the second perspective in the target video stream. This scenario may include outdoor live broadcasts, news broadcasts, large-scale sports events, evening parties, or conferences.

[0062] For example, in a live broadcast of a sports game between Team A and Team B, a camera captures video of the game scene (target video stream) and sends it to the server of the live broadcast platform (i.e., a computing device). In the target video stream captured by the camera, the game scene of Team A is the first video screen (preset video screen), and the game scene of Team B is the second video screen.

[0063] In another possible scenario, the first video screen is a video screen of the target application controlled by the second terminal; the second video screen is a video screen containing a preset information stream obtained from the target application or the local storage of the second terminal. The first video screen can be a video screen recorded from the screen of the second terminal, or a video screen of another terminal recorded after the second terminal is projected to another terminal. This application does not limit this.

[0064] Exemplarily, the target application includes a game application, and the preset information stream includes at least one of map data, player status, or game status. The first video screen may be a screen recorded when operating the game application in the second terminal, and the second video screen is a video screen generated in the game application based on information such as map data, player status, or game status.

[0065] In the above possible scenario, the game application can provide the second terminal with a transmission interface for obtaining a preset information stream. After the second terminal obtains the preset information stream, it sends the preset information stream together with the video stream of the recorded first video screen to the computing device.

[0066] The above target applications may also include office software applications, conference video applications, etc. The embodiments of the present application do not limit the specific applications.

[0067] In one example, if Figure 3 As shown, if the target application can provide a transmission interface for obtaining a preset information stream, when a live broadcast is initiated for the target application, a prompt will be displayed in the second terminal saying "The target application can provide a preset information stream, please confirm whether you want to obtain the preset information stream?" to provide multiple video screens. If "Yes" is selected, the second terminal will display three preset information stream options of "Map", "Player Status" and "Game Status", from which one or more items can be selected as other video screens (second video screens) of the target video stream.

[0068] S102: The computing device receives a request for playing a target video stream of a first terminal.

[0069] In this case, the computing device will send the default video picture of the target video stream, that is, the first video picture, to the first terminal.

[0070] S103 (optional): The computing device time-aligns the video portion and the audio portion of the target video stream of the first video picture.

[0071] In one possible implementation, the image frames of at least two video screens in the target video stream have different identifiers, and the image frames and audio frames of the target video stream both contain their own timestamps. If the image frame of the first video screen is marked as "1", the computing device will align the timestamps of the image frame and the audio frame marked as "1" to complete the time alignment of the video part and the audio part of the target video stream of the first video screen.

[0072] It is understandable that multiple video frames of the target video stream share the same audio. After the computing device selects one of the multiple video frames of the target video stream, it is necessary to align the video and audio in time to prevent the problem of mismatch between the picture and the sound.

[0073] S104: The computing device sends a first video picture of the target video stream to the first terminal.

[0074] In a possible implementation, the first terminal is installed with a client of video live broadcast software, and the computing device is installed with a server of video live broadcast software. After the user determines to play the target video stream on the client of the first terminal, the server of the computing device responds to the play operation and sends the first video picture (i.e., the default video picture) of the target video stream to the first terminal.

[0075] S105: The first terminal receives and plays the first video frame of the target video stream.

[0076] In a possible implementation, a client of a live video broadcasting software of the first terminal plays a first video frame of a target video stream.

[0077] S106: The first terminal receives an operation for starting a video screen switching function, and in response to the operation, starts the video screen switching function.

[0078] In one example, if Figure 4 As shown, Figure 4 A button for turning on the video screen switching function in the first terminal is shown. Clicking the button can turn on or off the video screen switching function.

[0079] S107: The first terminal receives an operation of switching the target video stream from the first video screen to the second video screen, and in response to the operation, sends a video screen switching request to the computing device.

[0080] The video picture switching request is used to switch the video picture playing control of the target video stream from the second terminal to the first terminal.

[0081] Specifically, the video screen switching request is a request to switch the video screen from the first video screen to the second video screen.

[0082] In a possible implementation, the video screen switching request includes an identifier of the image frame of the second video screen. For example, if the identifier of the image frame of the first video screen is 1 and the identifier of the image frame of the second video screen is 2, the video screen switching request includes switching the image frame of the target video stream from "1" to "2".

[0083] The operation of switching the target video stream from the first video screen to the second video screen includes, but is not limited to, sliding the screen left and right, sliding the screen up and down, clicking a button to switch, gesture switching, or voice switching.

[0084] In one example, if Figure 5 As shown, Figure 5 A schematic diagram of a video screen switching function included in a first terminal is shown. In the video screen switching function, the video screen switching operation can be performed by sliding the screen left or right or up and down. For example, the video screen is switched from one perspective to another, or in a game application, the video screen is switched from a player screen to a map screen.

[0085] In another example, Figure 6 As shown, Figure 6 A schematic diagram of a video screen switching function included in a first terminal is shown. In the video screen switching function, when the function button "first video screen" or "second video screen" at the bottom of the screen is clicked, the screen above the screen switches to the corresponding video screen. For example, the video screen is switched from one perspective to another, or in a game application, the video screen is switched from the player screen to the map screen.

[0086] It is understandable that in the traditional method, the user can only watch a fixed video screen on the first terminal, and the playback control of the video screen is performed on the second terminal, while in the method proposed in the embodiment of the present application, the control of the video screen can be switched from the second terminal to the first terminal, that is, the first terminal can control the video screen to switch from the current first video screen to the second video screen.

[0087] S108: The computing device receives a video screen switching request for the target video stream, and switches the first video screen to the second video screen in response to a control instruction of the first terminal.

[0088] S109 (optional): The computing device time-aligns the video portion and the audio portion of the target video stream of the second video picture.

[0089] In one possible implementation, the image frame of the second video screen is marked as "2", and the computing device switches to the video screen "2" based on the video screen switching request. The computing device aligns the image frame marked as "2" with the timestamp of the audio frame to complete the time alignment of the video part and the audio part of the target video stream of the second video screen.

[0090] It is understandable that since the first video picture and the second video picture share the audio part of the target video stream, in order to prevent the problem of picture and sound mismatch, the video part and audio part of the target video stream of the second video picture need to be time-aligned.

[0091] S110: The computing device sends the second video picture of the target video stream to the first terminal for playback.

[0092] Optionally, the first terminal is further provided with a function of restoring the default video screen, and when the user needs to restore the default video screen, the default video screen is restored based on the function. Methods for operating the default video screen restoration include but are not limited to: clicking a button, gestures, or voice.

[0093] In one example, if Figure 7 As shown, Figure 7 The figure shows a function button of "restore default video screen" included in the first terminal, and the default video screen can be returned by clicking the function button.

[0094] Optionally, in the case where the target video stream is a 3D video stream, in a live video broadcasting scenario, different video images in the target video stream are video images from different perspectives, and each perspective has a 360° video image at that perspective. If the first terminal is currently playing a first video image, the user can rotate the video image 360° at the first perspective, that is, the user can see a 360° image of the video at the first perspective. If the first terminal is currently playing a second video image, the user can rotate the video image 360° at the second perspective, that is, the user can see a 360° image of the video at the second perspective.

[0095] In one example, if Figure 8 As shown, the first terminal plays a first video screen, which is a video screen of the first perspective of a target video stream, and the target video stream is a 3D video stream. There is a person image in the first video screen, and since the target video stream is a 3D video stream, the user can click on the first terminal screen to rotate the first video screen to see a 360° screen of the person image.

[0096] Optionally, in the case where the target video stream is a 3D video stream, in the scenario where the second terminal operates the target application, for example, in the scenario where the second terminal operates a game application, the first video screen is a 2D screen recorded when the game application is operated in the second terminal, and the second video screen is a 3D video screen generated in the game application based on map data, player status or game status, etc. The user can move, zoom in, zoom out, rotate 360°, etc. the 3D video screen in the 3D second video screen played in the first terminal.

[0097] In the above optional situations, in some game applications, the game map also includes a real-time map and a preset map. The real-time map is a map video screen operated in real time in the second terminal. In this case, the user of the first terminal cannot move the real-time map and can only choose different viewing angles to view the real-time map. As for the preset map, since the map data is pre-loaded, the user of the first terminal can move, zoom in or out, and can choose different viewing angles to view the preset map.

[0098] It can be understood that in the above method, when there are multiple first terminals, the computing device uses CDN to send the first video pictures of the target video stream to multiple first terminals respectively.
