     Embodiment One 
       FIG.  1    is a flowchart of a method for controlling interactive live streaming co-hosting according to embodiment one of the present disclosure. This embodiment of the present disclosure is applied to the case where a live streaming interactive image is formed in the application scenario of interactive live streaming co-hosting. This method may be executed by an apparatus for controlling interactive live streaming co-hosting. The apparatus may be implemented in the form of software and/or hardware. The apparatus may be implemented by an electronic device. The electronic device may be a mobile terminal or a personal computer (PC) terminal. 
     As shown in  FIG.  1   , the method in this embodiment includes the steps below. 
     In S 110 , a first terminal acquires a first interactive image and receives a mirror interactive image of a second terminal. 
     In S 120 , the first terminal combines the first interactive image and the mirror interactive image to obtain a target interactive image. 
     The first terminal and the second terminal perform the live streaming co-hosting. The first terminal and the second terminal may be mobile terminals such as mobile phones or tablet computers, or may be electronic devices such as PC terminals. The first terminal or the second terminal may send a co-hosting request to a live streaming server, where the co-hosting request may include identifier information of the first terminal and the second terminal. The live streaming server performs co-hosting matching according to the co-hosting request to implement the live streaming co-hosting between the first terminal and the second terminal. 
     In this embodiment, the first terminal and the second terminal interact in the same interactive region of a display interface based on an interactive object. Exemplarily, referring to  FIGS.  2 A and  2 B ,  FIG.  2 A  is a diagram of a display region of live streaming co-hosting displayed by the first terminal according to embodiment one of the present disclosure, and  FIG.  2 B  is a diagram of a display region of live streaming co-hosting displayed by the second terminal according to embodiment one of the present disclosure. The display region may include the display region of a first host, the display region of a second host, and the interactive region (dotted region). The interactive region in  FIG.  2 A  or  FIG.  2 B  is only an example, and the interactive region may completely overlap, partially overlap, or completely not overlap with the display region of the first host and the display region of the second host, which is not limited to this embodiment. The size of the interactive region is less than or equal to the size of the overall display region. 
     The display region of the first host is configured to display the image or video of the first host acquired by the first terminal through a camera. The display region of the second host is configured to display the image or video of the second host acquired by the second terminal through a camera. The interactive region is configured to display the interactive image of the first terminal and the second terminal. At least one interactive object is included in the interactive image, for example, one interactive object is included in  FIG.  2 A  and  FIG.  2 B  and moves along the arrow direction. The interactive object is not limited to the spherical object shown in  FIG.  2 A  and  FIG.  2 B  and may change in real time according to an interactive scenario. The movement manner of the interactive object may also be determined according to the interactive scenario. The movement direction of the interactive object is not limited to the movement directions shown in  FIG.  2 A  and  FIG.  2 B . 
     In an embodiment, the interactive scenario may also include a control object, that is, an object that may be controlled by a control instruction input by a host. In some embodiments, the control object may be different from the interactive object, and the control object of the first terminal and the control object of the second terminal may be different, that is, the first terminal and the second terminal correspond to different control objects separately. For example, referring to  FIG.  2 C ,  FIG.  2 C  is a diagram of an interactive scenario according to embodiment one of the present disclosure. In  FIG.  2 C , each of the first terminal and the second terminal corresponds to one control object, and the corresponding control object may be controlled to change the position, speed, direction, and shape. An interactive object different from the control object is included in  FIG.  2 C  and moves in the interactive scenario. In some embodiments, the control object may be one or more of the interactive objects, that is, the first terminal or the second terminal may control one or more of the interactive objects so that the one or more interactive objects are controlled to change the position, speed, direction, and shape. 
     As can be seen from  FIGS.  2 A and  2 B , the position of the display region of the first host in the display region of the first terminal is the same as the position of the display region of the second host in the display region of the second terminal. That is, in any terminal, the display region of the operation user of this terminal should be located at the same position, for example, on the left side of a co-hosting display region. Similarly, the interactive image displayed in the interactive region is also determined by the interactive images acquired by two terminals. The first terminal acquires the first interactive image, the second terminal acquires the second interactive image, the sum of the size of the first interactive image and the size of the second interactive image is the same as the size of the overall interactive image, and the size of the first interactive image may be the same as the size of the second interactive image. Exemplarily, referring to  FIGS.  2 A and  2 B , in the display region of the first terminal, the boundary between the display region of the first host and the display region of the second host is used as a split line, the interactive image located in the display region of the first host is used as the first interactive image. Similarly, in the display region of the second terminal, the boundary between the display region of the first host and the display region of the second host is used as a split line, and the interactive image located in the display region of the second host is used as the second interactive image. Referring to  FIG.  2 C , in the interactive image displayed by any terminal, the control object corresponding to the current terminal is located on the same side, for example, on the left side of the interactive region. The interactive object moves in the interactive region, that is, the first interactive image and/or the second interactive image includes at least one interactive object. The interactive object moves in the first interactive image and the second interactive image. 
     To form a complete interactive image, the first terminal acquires the first interactive image, and the second terminal acquires the second interactive image. In an embodiment, the first terminal may acquire the first interactive image in the following manners: The first terminal identifies the control information in a video image of a first user, and controls the control object in the interactive scenario based on the control information; and the first interactive image corresponding to the interactive region of the first terminal is acquired by frame. The first terminal may be configured with a camera, and the camera is configured to acquire a video of the first host. The first terminal identifies control information in multiple frames of video images in the video to control the control object in the interactive scenario. Identification of the control information in the video images may be determined by identifying position information and/or posture information of keypoints of the first host. For example, these keypoints may be, but are not limited to, a finger, an arm, a head, etc. For example, the position information of the control object may be adjusted through the position information of the keypoints, and the direction or shape of the control object may be adjusted through the posture information of the keypoints. In some embodiments, the control information of the control object may be obtained by identifying the face coordinate, where the ordinate of the face coordinate corresponds to longitudinal control information of the control object, and the abscissa of the face coordinate corresponds to the lateral control information of the control object. The face coordinate may be the coordinate of the center point of the face or the coordinate of any specified organ. 
     According to the control information of the multiple frames of video images in the video of the first host, data of the control object in the interactive region corresponding to the first terminal is determined frame by frame. The first interactive image of a corresponding frame is formed based on the data of the control object and/or the data of the interactive object in the interactive region of the first terminal, the interactive region corresponding to the first terminal may be a part of the interactive region on the side where the display region of the first host is located, and the part of the interactive region may be half of the overall interactive region. 
     Similarly, the second terminal acquires the second interactive image based on the preceding manner. The second terminal sends the acquired second interactive image to the game server, and the game server performs the mirror processing on the received second interactive image to obtain the mirror interactive image and transmits the mirror interactive image to the first terminal. The game server may directly transmit the mirror interactive image to the first terminal or may transmit the mirror interactive image to the first terminal through a realtime communication (RTC). 
     The first interactive image and the second interactive image respectively carry the timestamp of an acquisition time, and the mirror interactive image carries the timestamp accordingly. The timestamp of the mirror interactive image is the same as the timestamp of the second interactive image on which the mirror processing is performed. 
     The first terminal combines the first interactive image and the mirror interactive image that have the same timestamp to obtain the target interactive image of the first terminal. For example, the position of the first interactive image is unchanged, and the mirror interactive image and the first interactive image are aligned and spliced to form the target interactive image. The first interactive image and the mirror interactive image are combined through the timestamp, in this manner, synchronization of interactive images is ensured, and confusion of the interactive images is avoided. Multiple frames of target interactive images form a target interactive video displayed by the first terminal, the target interactive video is displayed in the live streaming co-hosting display interface of the first terminal, and the target interactive video is pushed to an audience terminal corresponding to the first terminal. 
     On the basis of the preceding embodiment, the first terminal sends the first interactive image to the game server so that the game server is caused to transmit the mirror interactive image of the first interactive image to the second terminal after performing the mirror processing on the first interactive image. The second terminal forms the target interactive image of the second terminal based on the acquired second interactive image and the mirror interactive image of the first interactive image. The second interactive image in the target interactive image of the second terminal is located on the left side of the interactive region, and the mirror interactive image of the first interactive image is located on the right side of the interactive region, so as to form a complete interactive image. 
     The layout of the display region displayed by the first terminal or the second terminal is not limited to the layout shown in  FIG.  2 A  or  FIG.  2 B . Referring to  FIG.  2 D ,  FIG.  2 D  is a diagram of another display region of live streaming co-hosting according to embodiment one of the present disclosure. In  FIG.  2 D , the display region of the first host, the display region of the second host, and the interactive region do not overlap, the interactive region may include the interactive object and/or the control object, and the interactive object and/or the control object moves in two interactive images of the interactive region. The layout of the display region of the first host, the display region of the second host, and the interactive region in  FIG.  2 D  may be adjusted according to design requirements, which is not limited in this embodiment. 
     In the technical schemes of this embodiment, the first terminal combines the acquired first interactive image with the received mirror interactive image of the second interactive image of the second terminal to obtain the target interactive image suitable for the first terminal to display. In this manner, the clarity and accuracy of the interactive images in the interactive region of different terminals are ensured in the live streaming scenario, and the confusion of the interactive images is avoided. 
     Embodiment Two 
       FIG.  3    is a flowchart of a method for controlling interactive live streaming co-hosting according to embodiment two of the present disclosure. This embodiment is described on the basis of the preceding embodiment. The method includes the steps below. 
     In S 210 , the first terminal acquires the first interactive image and receives the mirror interactive image of the second terminal. The first terminal is co-hosted with the second terminal. The second interactive image of the second terminal is mirrored to obtain the mirror interactive image of the second terminal. 
     In S 220 , the first terminal combines the first interactive image and the mirror interactive image to obtain the target interactive image. 
     In S 230 , the first terminal acquires a first video stream, receives a second video stream of the second terminal, and forms an initial video merging stream based on the first video stream and the second video stream. 
     In S 240 , the first terminal adds the target interactive image to the initial video merging stream to generate a target video merging stream. The target video merging stream is used to push to an audience terminal of the first terminal. 
     Each of the first terminal and the second terminal is configured with a camera. The first terminal acquires the first video stream through the first camera, and the first video stream may be a video stream including the first host. The second terminal acquires the second video stream through the second camera, and the second video stream may be a video stream including the second host. The second terminal transmits the second video stream to the first terminal, for example, the video stream may be transmitted through the realtime communication. For example, the first terminal sends the acquired first video stream to the realtime communication, the second terminal sends the acquired second video stream to the realtime communication, and the realtime communication transmits the first video stream to the second terminal and transmits the second video stream to the first terminal. 
     The first terminal performs stream merging processing on the first video stream and the second video stream to obtain the initial video merging stream. Based on the first video stream and the second video stream, the initial video merging stream is formed in the following manners: a stream merging position of the first video stream and a stream merging position of the second video stream are determined according to the identifier of the first video stream and the identifier of the second video stream; and the stream merging processing is performed on the first video stream and the second video stream according to the stream merging positions to form the initial video merging stream. Referring to  FIG.  2 A , the display region of the first host in  FIG.  2 A  is the stream merging position of the first video stream, and the display region of the second host is the stream merging position of the second video stream. For any terminal, the stream merging position of the video stream acquired by the current terminal may be a first preset position located in the live streaming co-hosting display region of the current terminal, for example, may be a left side position. The stream merging position of the video stream acquired by a co-hosting terminal is located at a second preset position located in the live streaming co-hosting display region of the current terminal, for example, may be a right side position. 
     The first terminal performs the stream merging processing on the first video stream and the second video stream at corresponding stream merging positions according to the identifier of the first video stream and the identifier of the second video stream to obtain the initial video merging stream. In an embodiment, the stream merging processing may be performed on the first video stream and the second video stream according to the stream merging positions in the following manner: the stream merging processing is performed on a video frame of the first video stream and a video frame of the second video stream according to the stream merging positions based on timestamps of multiple video frames of the first video stream and timestamps of multiple video frames of the second video stream, where the video frame of the first video stream and the video frame of the second video stream have the same timestamp. The stream merging processing is performed on the first video stream and the second video stream based on the timestamps. In this manner, the live streaming delay of two video streams is avoided, and the synchronization of the video streams is improved. 
     The first terminal adds the target interactive image to multiple video frames corresponding to the initial video merging stream to obtain the target video merging stream of the first terminal. The target interactive image and multiple video frames in the initial video merging stream are each provided with the timestamp, and the target interactive image is added into a video frame having the same timestamp as the target interactive image. 
     In some embodiments, the target interactive image includes the data of the control object and/or the data of the interactive object. The control object and/or the interactive object are rendered into a corresponding video frame based on the data to complete the drawing of the target interactive image. In some embodiments, pixel values of multiple pixels in the target interactive image may be rendered in the corresponding video frame based on the position of the interactive region in the display interface, so as to complete the drawing of the target interactive image. When the interactive region overlaps with the display position of the first host and the display position of the second host, the image background of the target interactive image is transparent to avoid blocking of the image in the initial video merging stream. Accordingly, referring to  FIGS.  2 A and  2 B , the size of the target interactive image is less than or equal to the size of each image frame in the initial video merging stream. When the interactive region does not overlap with the display position of the first host and the display position of the second host, the image background of the target interactive image may be configured according to requirements. Drawing of the target interactive image may be rendering of a display region corresponding to a video frame of the target interactive image and a display region corresponding to a video frame of the initial video merging stream respectively, where the two video frames have the same timestamp. 
     The target video merging stream is displayed on the first terminal, and the target video merging stream is pushed to the audience terminal corresponding to the first terminal. In this manner, it is ensured that in the live streaming images displayed on audience terminals, the host of the live streaming room is located at the same preset position for all audiences. Pushing the target video merging stream may be implemented based on a content delivery network (CDN) server. 
     In this embodiment, the first terminal and the second terminal are terminals having the local stream merging function. Instead of performing video stream merging by the live streaming server, the video stream merging is performed by the first terminal, so the delay of a video merging stream is reduced and the lag of a video stream is avoided. 
     For example, referring to  FIG.  4   ,  FIG.  4    is a diagram of a live streaming flow according to embodiment two of the present disclosure. The camera acquires the first video stream and transmits the first video stream to an effect processing module (effect sdk). The effect processing module performs beautification processing and special effect processing on the acquired first video stream, receives the second video stream, and performs the stream merging processing on the first video stream and the second video stream to obtain the initial video merging stream. The effect processing module acquires the first interactive image and receives the mirror interactive image of the second interactive image, combines the first interactive image and the mirror interactive image, and then draws the obtained target interactive image into the initial video merging stream to obtain the target video merging stream, and the target video merging stream is transmitted to a livecore. At the same time, an audio stream is acquired by a sound-pick-up device of the first terminal, or a sound effect audio stream in the first terminal is invoked. The audio stream is transmitted to the livecore, and the livecore performs the stream merging processing on the video stream and the audio stream to push the merged video stream to an audience terminal through the CDN, so as to display the video stream on the first terminal based on a surface view. 
     Steps S 210  to S 220  and step S 230  may be executed sequentially or may be executed synchronously. Alternatively, step S 230  may be firstly executed, and then steps S 210  to S 220  are executed. 
     In the technical schemes of this embodiment, the first terminal acquires the first interactive image and the first video stream. The second terminal acquires the second interactive image and the second video stream. The first terminal receives the second video stream and the mirror interactive image of the second interactive image, splices the first interactive image and the mirror interactive image to obtain the target interactive image, performs the stream merging processing on the first video stream and the second video stream to obtain the initial video merging stream, and draws multiple frames of target interactive images into video frames corresponding to the initial video merging stream to obtain the target video merging stream. In this manner, the combination of a host video image and an interactive image in the live streaming co-hosting scenario is implemented, the accuracy of an interactive video merging stream is improved, and confusion of a merging stream is avoided. 
     On the basis of the preceding embodiments, the interactive scenario of the first terminal and the second terminal may be a game scenario, and the game server performs score addition/subtraction and victory/defeat determination in the game scenario. To ensure time synchronization in the game scenario, the first terminal receives the control signaling sent by the game server and adjusts the state of the interactive scenario in which the first terminal and the second terminal are located based on the control signaling. The control signaling is sent by the game server to the first terminal and the second terminal synchronously. 
     The same control signaling is sent by the game server to two co-hosted terminals synchronously, so that the first terminal and the second terminal synchronously execute the preceding control signaling, thereby improving the synchronization of the game scenario. The control signaling may include start signaling, end signaling, and state switch signaling. The start signaling is used to control the game scenario to be started. The end signaling is used to control the game scenario to be ended. The state switch signaling is used to perform state switching during the process of the game scenario. The type of the state switch signaling and the number of the state switch signaling may be configured according to different game scenarios. 
     The preceding control signaling is configured to synchronously control the first terminal and the second terminal at the start, the end, and in the process of the game scenario. In this manner, the synchronization of the scenario is implemented, and the interaction disorder caused by a delay is reduced. 
     Embodiment Three 
       FIG.  5    is a flowchart of a method for controlling interactive live streaming co-hosting according to embodiment three of the present disclosure. This embodiment of the present disclosure is applied to the case where a live streaming interactive image is formed in the application scenario of interactive live streaming co-hosting. This method may be executed by the apparatus for controlling interactive live streaming co-hosting. The apparatus may be implemented in the form of software and/or hardware. The apparatus may be implemented by the electronic device, and the electronic device may be a server. 
     In S 310 , the game server receives the second interactive image sent by the second terminal and mirrors the second interactive image to obtain the mirror interactive image. 
     In S 320 , the game server transmits the mirror interactive image to the first terminal based on a realtime communication to enable the first terminal to form the target interactive image based on the acquired first interactive image and the mirror interactive image. 
     In this embodiment, for the first terminal, the game server mirrors the second interactive image sent by the second terminal to obtain the mirror interactive image and transmits the mirror interactive image to the first terminal, so that the first terminal is caused to form the target interactive image based on the first interactive image and the mirror interactive image. In this manner, there is no need to process the first interactive image in the preceding process, the correctness of the target interactive image is ensured, and the calculation amount of the game server is reduced at the same time. 
     Similarly, for the second terminal, the game server mirrors the first interactive image sent by the first terminal to obtain the mirror interactive image and transmits the mirror interactive image to the second terminal, so that the second terminal is caused to form the target interactive image based on the acquired second interactive image and the mirror interactive image, and there is no need to process the second interactive image in the preceding process. 
     In an embodiment, the second interactive image may be mirrored in the following manner: the second interactive image is mirrored by using the common edge of the second interactive image and the first interactive image as a mirror edge. For example, an edge in the second interactive image consistent with the center line of the interactive region may be used as the mirror edge. Thus, it is ensured that the mirror interactive image obtained after the mirror processing is correctly connected with the first interactive image, avoiding the confusion of the target interactive image. The second interactive image may be mirrored based on the mirror edge, multiple pixels in the second interactive image are correspondingly disposed at corresponding positions on the other side of the mirror edge. Exemplarily, when the mirror edge is a longitudinal edge, the ordinates of the pixels are kept unchanged, and the difference value between the abscissa of the current pixel and the abscissa of the mirror edge is the same as the difference value between the abscissa of the mirror pixel and the abscissa of the mirror edge. Similarly, when the mirror edge is a lateral edge, the abscissas of the pixels are kept unchanged, and the difference value between the ordinate of the current pixel and the ordinate of the mirror edge is the same as the difference value between the ordinate of the mirror pixel and the ordinate of the mirror edge. 
     In the technical schemes of this embodiment, after the game server mirrors an interactive image acquired by one of the two co-hosted terminals, the interactive image obtained after the mirror processing is transmitted to the other terminal so that the other terminal combines the interactive images to obtain a target interactive image satisfying the display requirement of the other terminal. For any terminal, a target interactive image satisfying display requirements of multiple terminals may be obtained based on the preceding method. Moreover, the interaction requirement and the display requirement of live streaming co-hosting are both considered, and the accuracy of the target interactive image displayed by the multiple terminals is ensured. 
     In an embodiment, the game server may send the control signaling to the first terminal and the second terminal synchronously to enable the first terminal and the second terminal to synchronously execute the control signaling. The control signaling includes start signaling, end signaling, and state switch signaling. The preceding control signaling is configured to synchronously control the first terminal and the second terminal at the start, the end, and in the process of the game scenario. In this manner, the synchronization of the scenario is implemented, and the interaction disorder caused by a delay is reduced. 
     Embodiment Four 
     In this embodiment, the game interactive scenario is used as an example to describe the image forming method of the interactive region in the method for controlling interactive live streaming co-hosting provided in the preceding embodiments. As shown in  FIG.  2 C , the control object of the current host and the control object of a co-hosting host are each a baffle, and the interactive object is a ball. The current host may control the baffle corresponding to the current host to move up and down in the display region so that after hitting the baffle corresponding to the current host, the ball bounces back to the display region in which the baffle corresponding to the co-hosting host is located.  FIG.  2 C  merely exemplarily shows that the ball moves horizontally from the display region in which the baffle corresponding to the current host is located to the display region in which the baffle corresponding to the co-hosting host is located. The ball may move in any direction in the game interactive scenario, as long as the bounce law after the ball hits the baffle is conformed. 
     In this embodiment, the current host controls the up and down movement of the baffle by changing the position of the face, that is, the current host nods down, which represents that the baffle is controlled to move down, while the current host looks up, which represents that the baffle is controlled to move upward. The terminal of the current host identifies the control information in the video image of the current host, and the control information is the ordinate of the face of the current host. The position data of the baffle corresponding to the current host in the display region in the game interactive scenario is determined frame by frame based on the control information. The interactive image for the current host is formed based on the rendering of the position data of the baffle and the position data of the ball. In the interactive image of the current host, the baffle corresponding to the current host is always located on the left side of the interactive image of the current host. Similarly, on the terminal side of the co-hosting host, the interactive image of the co-hosting host is formed by rendering in the same manner as described above. In the interactive image of the co-hosting host, the baffle corresponding to the co-hosting host is always located on the left side of the interactive image of the co-hosting host. 
     The terminal of the current host combines the interactive image acquired by the terminal of the current host and the mirror image of the interactive image of the co-hosting host to form the image of the interactive region displayed on the terminal of the current host. In this manner, in the image of the interactive region, the baffle corresponding to the current host and the baffle corresponding to the co-hosting host are located on two sides of the image of the interactive region, and the baffle corresponding to the current host is located on the left side of the image of the interactive region, as shown in  FIG.  2 C . Similarly, an image composed of the interactive image of the co-hosting host and the mirror image of the interactive image of the current host is formed in the interactive region on the terminal side of the co-hosting host. The baffle corresponding to the co-hosting host is located on the left side of the image of the interactive region. 
     Through the preceding methods, the image in the interactive region is continuously rendered on the terminal of the host, and the image in the interactive region is pushed to the audience terminal in the live streaming room of the host so that the image in the interactive region displayed in the audience terminal is consistent with the image in the interactive region on the terminal of the host.
