All the above optional technical solutions may be combined in any way to form optional embodiments of the present disclosure, which will not be repeated here.

Fig. 2A is a flow chart of a method for live video broadcasting according to an exemplary embodiment, and the interaction subjects are a host terminal, a server and an audience terminal. Wherein, the host terminal refers to a mobile terminal, and the audience terminal refers to either a mobile terminal or a fixed terminal. Taking the anchor terminal firstly starting the front camera to take video pictures, and then starting the rear camera to take video pictures as an example, as shown in FIG. 2A , it includes the following steps.

In step 201, the anchor terminal plays the first video image captured by the front camera on the live video page.

Usually, for audience users, the anchor image is what they want to see the most. Similarly, for anchor users, the anchor image is also what they want to show to everyone. Therefore, the importance of the external scene image is generally lower than that of the anchor image. of. Therefore, when the anchor user uses the anchor terminal for live broadcast, the first choice is to start the front camera to shoot. Wherein, the host terminal may be a smart phone or a tablet computer, which is not specifically limited in this embodiment of the present disclosure.

The live broadcast software on the anchor terminal can obtain the first video screen captured by the front camera in real time, and play and display it on the live video page. At the same time, the live broadcast software on the anchor terminal will also upload the first video screen captured by the front camera and the live broadcast room logo to the server in real time, and the server will determine the audience user IDs who watch the live broadcast of the anchor user according to the live broadcast room logo , and deliver the first video image to the audience terminal according to the audience user ID. If the audience terminal is also installed with the live broadcast software, the first video screen can be displayed synchronously with the anchor terminal, and the playback progress of the video screen is consistent. It should be noted that in the embodiment of the present disclosure, the content captured by the front camera is collectively referred to as the first video frame, and similarly to this, the content captured by the rear camera is captured by the second video frame in subsequent steps. Collectively. Wherein, the live room identifier refers to the name or number of the live room, etc., which may be generated by the server for the live room. The viewer terminal can enter the live broadcast room by selecting or inputting the live broadcast room ID.

In step 202, the anchor terminal displays the first activation option of the rear camera on the live video page; when the trigger operation of the first activation option is detected, the rear camera is activated for shooting.

In some special scenarios, sometimes the host user may need to display the external scenes, such as showing the audience users how heavy the rainstorm outside is, and live broadcasting the scene of the accident that happened in front of them. In the embodiment of the present disclosure, in order to facilitate the host user to display the scene, an option to activate the rear camera is provided on the live video page.

Wherein, the first start option may specifically be a virtual button that can be clicked by the anchor user. When the anchor terminal detects that the anchor user has clicked the first start option, the live broadcast software actively invokes the rear camera to shoot video images. The first start option may be displayed in any area on the live video page except for playing video images, which is not specifically limited in this embodiment of the present disclosure.

The above step 201 and step 202 describe the process of how to restart the rear camera to take video pictures when only the front camera is currently in the shooting state. It should be noted that if only the rear camera is currently shooting, the second start option of the front camera can also be displayed on the live video page. After the host terminal detects the trigger operation of the second start option, it starts the front camera to shoot video images. That is, when one camera is started, another camera can be triggered to start through the start option displayed on the live video page.

In step 203, the anchor terminal synthesizes the first video frame captured by the front camera and the second video frame captured by the rear camera to obtain the target video frame.

In the embodiment of the present disclosure, since both the front camera and the rear camera of the anchor terminal are in the shooting state, the anchor picture and the exterior scene picture will be captured in real time. After the live broadcast software acquires the first video screen captured by the front camera and the second video screen captured by the rear camera, in order to display the anchor screen and the external scene screen at the same time, it will combine the first video screen and the second video screen. The time-frequency images are synthesized in the following ways, so that the target video images shown in Figure 2B to Figure 2D can be displayed on the host terminal.

In the first manner, according to the left-right split-screen mode shown in FIG. 2B , the first video image and the second video image are synthesized.

For the first method, the left-right split-screen mode refers to dividing the display area used for playing video images on the live video page into left and right parts. One part is used to display the first video image captured by the front camera, and the other part is used to display the second video image captured by the rear camera. Limited by the screen size of the anchor terminal, the left-right split-screen mode is usually used when the anchor terminal is in a landscape state. Nowadays, all terminals are equipped with sensors, and according to the sensor information sent back by the sensors, it can be judged whether the current posture of the anchor terminal is in a landscape state or a portrait state. In the embodiment of the present disclosure, the anchor terminal may be configured with a magnetic field sensor, a gyroscope sensor, a six-axis orientation sensor or a nine-axis rotation vector sensor, etc., which is not limited in this embodiment of the present invention.

When synthesizing video images according to the above-mentioned split-screen mode, a method of synthesizing image frames one by one is usually adopted. For example, after the rear camera is started, after the image frame captured by the front camera and currently being played is trimmed to a certain extent, after the first frame of image captured by the rear camera is also trimmed to a certain extent, the trimmed Two image frames are synthesized according to the left-right split-screen mode, and the second frame image captured by the rear camera and the image captured by the front camera and played in the next frame are also synthesized according to the left-right split-screen mode, and so on. The example does not specifically limit this.

The second method is to synthesize the first video image and the second video image according to the upper and lower screen split mode shown in FIG. 2C .

For the second method, the upper and lower split screen mode refers to dividing all the display area used for playing video images on the live video page into upper and lower parts. One part is used to display the first video image captured by the front camera, and the other part is used to display the second video image captured by the rear camera. Limited by the size of the anchor terminal screen, the up and down split screen mode is usually used when the anchor terminal is in a vertical screen state. When synthesizing video images according to the above-mentioned split-screen mode, a method of synthesizing image frames one by one is usually adopted. For example, after the rear camera is started, after the image frame captured by the front camera and currently being played is clipped to a certain extent, after the first frame image captured by the rear camera is also clipped to a certain extent, the clipped two The first image frame is synthesized according to the upper and lower split screen mode, and the second frame image captured by the rear camera and the image shot by the front camera and played in the next frame are also synthesized according to the upper and lower split screen mode, and so on, the embodiment of the present disclosure This is not specifically limited.

In the third way, according to the picture-in-picture mode shown in Figures 2D and 2E, the first video picture and the second video picture are synthesized;

For the third method, the picture-in-picture mode refers to dividing all display areas used for playing video images on the live video page into two parts. One of the sections is contained within the area of another section. Similar to the above two cases, one part is used to display the first video image captured by the front camera, and the other part is used to display the second video image captured by the rear camera. The picture-in-picture mode is applicable when the host terminal is in portrait or landscape mode. When synthesizing video images according to the above-mentioned split-screen mode, a method of synthesizing image frames one by one is usually adopted. For example, after the rear camera is started, the width and height of the image frame captured by the front camera and currently being played are compressed to a certain extent, and the width and height of the first frame image captured by the rear camera are compressed to a certain extent, etc. After compression, the compressed two image frames are synthesized according to the picture-in-picture mode, and the second frame image captured by the rear camera and the image captured by the front camera and played in the next frame are also synthesized according to the picture-in-picture mode , and so on, which is not specifically limited in the embodiments of the present disclosure.

In step 204, the host terminal plays the target video frame, and sends the target video frame and the live room identifier to the server.

In the embodiment of the present disclosure, after the live broadcast software of the anchor terminal synthesizes the first video image and the second video image, it can directly play the target video image on the live video page of the anchor terminal. If the target video screen is synthesized according to the left and right split screen mode, then the host terminal will play the first video screen in the first display area of the live video page, and the second video screen in the second display area as shown in Figure 2B . Optionally, the first display area is located on the left side of the second display area.

If the target video screen is synthesized according to the upper and lower split screen mode, then the host terminal will play the first video screen in the third display area of the live video page, and the second video screen in the fourth display area, as shown in Figure 2C . Optionally, the third display area is located above the fourth display area.

If the target video image is synthesized according to the picture-in-picture mode, then the host terminal will play the first video image in the fifth display area of the live video page, and the second video image in the sixth display area, as shown in Figure 2D . Optionally, the sixth display area is located in the fifth display area.

In the embodiment of the present disclosure, the anchor terminal adopts a dual-camera live broadcast method with a front camera and a rear camera. In order to enable the audience terminal to simultaneously see the anchor picture and the outside scene picture, the anchor terminal will send the target video picture and live broadcast to the server in real time. room identifier, so that the server determines all audience users who watch the anchor's live broadcast according to the live broadcast room identifier, and sends the target video picture to all audience users. For the detailed process, see step 205 below.

It should be noted that, in order to improve user experience, the embodiment of the present disclosure also provides a synthesis mode switching option on the live video page of the anchor terminal. After the anchor user triggers the synthesis mode switching option, it will trigger the generation of a synthesis mode switching instruction. The synthesis mode switching instruction indicates the synthesis mode of the first video frame and the second video frame. Wherein, the synthesis mode switching option specifically includes two types, taking the first switching option and the second switching option as an example, wherein the first switching option is used to instruct the anchor terminal to switch the first video screen and the second video screen The display area is composited. That is, when the anchor terminal detects the trigger operation of the first switching option, from now on, the anchor terminal will combine the first video image captured by the front camera and the second image captured by the rear camera based on the switched display area. The two video images are synthesized according to the initial split-screen mode to obtain a new target video image, and the new target video image is sent to the audience terminal. At the same time, the anchor terminal plays the second video picture in the display area where the first video picture was originally played, and plays the first video picture in the display area where the second video picture was originally played.

For example, referring to Figure 2D and Figure 2E, for the picture-in-picture mode, if the initial anchor terminal displays the first video picture in the main display area, and the second video picture is displayed in the secondary display area, then in After the host user clicks the first switching option, the host terminal will display the first video image in the secondary display area, and display the second video image in the main display area. Wherein, the area of the main display area is generally much larger than the area of the auxiliary display area.

In another embodiment, in addition to switching the video image between different display areas, the embodiments of the present disclosure also support the process of switching the video image between different split-screen modes. Specifically, a second switching option of split-screen mode is provided on the live video page of the anchor terminal. Wherein, the second switching option may be specifically composed of a drop-down list showing a split-screen mode and an OK button. When the anchor user selects a sub-item in the drop-down list and clicks the OK button, the anchor terminal determines to detect the trigger operation of the second switching option, and determines the split-screen mode indicated by the sub-item as the target split-screen mode; At first, the host terminal synthesizes the first video frame and the second video frame according to the target split-screen mode to obtain a new target video frame, and sends the new target video frame to the audience terminal. In addition, each split-screen mode may also correspond to a separate switching option, which is not specifically limited in this embodiment of the present disclosure.

For example, referring to Fig. 2B and Fig. 2C, if the initial anchor terminal displays the target video picture as shown in Fig. The video images are synthesized in the upper and lower split-screen mode shown in FIG. 2C , so that an image such as that shown in FIG. 2C will be displayed on the anchor terminal.

In step 205, after receiving the target video frame and the live room ID, the server determines the audience user ID associated with the live room ID, and sends the target video frame to the audience terminal based on the audience user ID.

In the embodiment of the present disclosure, for a live broadcast room, the server generally stores the corresponding relationship between the live room ID and the viewer user ID, so as to record the audience users who watch the live video broadcast of the live room. Therefore, after receiving the live broadcast room identifier, the server can determine the viewer user ID associated with the live broadcast room identifier according to the above correspondence, and deliver the target video image to all viewer users in the live broadcast room.

In step 206, after receiving the target video frame sent by the server, the viewer terminal determines the split-screen mode used when synthesizing the target video frame, and plays the target video frame on the live video page according to the split-screen mode.

In the embodiment of the present disclosure, after the audience terminal receives the target video picture sent by the host terminal, if the target video picture is synthesized according to the left and right split screen mode, then the audience terminal will display the video on the live video page as shown in Figure 2B. The first display area plays the first video image, and the second display area plays the second video image. Optionally, the first display area is located on the left side of the second display area.

If the target video image is synthesized according to the upper and lower split screen mode, then the audience terminal will play the first video image in the third display area of the live video page, and the second video image in the fourth display area as shown in Figure 2C. picture. Optionally, the third display area is located above the fourth display area.

If the target video image is synthesized according to the picture-in-picture mode, then the audience terminal will play the first video image in the fifth display area of the live video page, and the second video image in the sixth display area as shown in Figure 2D. picture. Optionally, the sixth display area is located in the fifth display area.

It should be noted that the viewer terminal displays the target video image in the same way as the host terminal, so that it can be ensured that the live images displayed by the anchor terminal and the audience terminal are consistent. For example, the picture displayed on the left side of the anchor terminal is the same as the picture displayed on the left side of the audience terminal. In this way, assuming that the host user informs the audience users to pay attention to something that appears in the left screen, the audience users will not need to find it on the right screen.

According to the method provided by the embodiment of the present disclosure, the anchor terminal can start the front camera and the rear camera to shoot video images of the dual cameras, and combine the first video image captured by the front camera and the second video image captured by the rear camera. Synthesize to display the target video screen covering the screens captured by the front and rear cameras, and support sending the target video screen to the audience terminal, so that the audience terminal also plays the target video screen synchronously, so the display of the anchor screen and the location screen can be completed at the same time. It overcomes the defect that the anchor cannot show the exterior scene when he wants to show himself, and cannot show himself when he wants to show the exterior scene. The live broadcast effect is better and the user stickiness is high.
