The method of the present embodiment may be executed by a live broadcast apparatus disclosed in the embodiments of the present disclosure, and the apparatus may be implemented by software and/or hardware, and may be integrated on any electronic device with computing capability.
As shown in fig. 1, the live broadcasting method disclosed in this embodiment may include:
s101, acquiring sound and shape data of the anchor and a target control instruction from a target client, controlling target cloud equipment according to the target control instruction, and generating target video stream data.
The target client represents a smart terminal device, and may be, for example, a smart phone, a smart watch, a tablet computer, a notebook computer, or any electronic device with a smart operating system. The anchor represents a holder of the target client, and the anchor performs live broadcasting through the target client. The voice and shape data comprise voice data and shape data of the anchor, wherein the voice data can be collected real voice of the anchor, or synthetic voice generated by a TTS (Text To Speech, TTS) technology, and the like; the appearance data may be a real appearance image of the collected anchor, or may be a virtual anchor image generated by a character model technology, and the like.
The cloud equipment refers to equipment which applies a cloud computing technology to a server and realizes cloud service through the server, and can realize numerous functions through a network by means of a self-contained system and the server erected by manufacturers. The types of the cloud device include, but are not limited to, a cloud mobile phone, a cloud computer, a cloud tablet, a cloud television, and the like, and the specific type of the cloud device is not limited in this embodiment. In this embodiment, the server is equipped with at least one cloud device, each client corresponds to one cloud device having a control authority, and the target cloud device represents a cloud device having a control authority of the target client.
In one implementation mode, the anchor clicks a pre-installed cloud equipment application icon in a target client, the target client correspondingly generates a connection request and sends the connection request to the server, the server performs identity verification on the target client, and after the identity verification is passed, communication connection with the target client is established. Further, the server controls the target cloud equipment to render the cloud equipment interface, performs video coding on the rendered interface, generates video stream data, and sends the video stream data to the target client. And after receiving the video stream data, the target client decodes the video so as to display the cloud equipment interface through a screen. When the target client logs in the cloud device for the first time, the cloud device interface may be a desktop interface of the cloud device.
The anchor can apply control operation on the cloud equipment interface through the screen, the target client determines screen coordinates related to the control operation according to the control operation of the user, and generates a target control instruction containing the screen coordinates. The embodiment does not limit the specific form of the control operation, and all the ways of controlling the cloud device interface can be regarded as the control operation of the cloud device interface.
For example, when the cloud device interface is a desktop interface, the anchor can click any application icon in the desktop interface through the screen, and the target client generates a target control instruction containing the application screen coordinates so as to start an application program corresponding to the application icon installed in the cloud device.
For another example, when the cloud device interface is a game interface of a game application, the anchor may perform a press and drag operation through a screen, and the target client generates a target manipulation instruction including screen coordinates according to the screen coordinates involved in the press and drag operation, so as to control movement or attack of a game character.

And the target client generates a target control instruction containing the screen coordinates according to the screen coordinates related to the left-hand stroke or right-hand stroke operation and the screen coordinates related to the pressing and dragging operation.
The target client side collects sound and shape data of the anchor through collection equipment installed on the target client side, wherein the sound and shape data can be collected in real time or can be collected when the anchor applies control operation on a cloud equipment interface. Optionally, when the anchor applies a control operation on the cloud device interface, the target client acquires real voice data of the user through an installed sound pickup device, such as a microphone, and also acquires real appearance data of the user through an installed image acquisition device, such as a video camera or a still camera. And the target client performs associated packaging on the real voice data and the real appearance image data to generate sound and shape data.
And the target client sends the target control instruction and the audio data to the server together. And the server receives the audio data and the target control instruction, and controls the cloud equipment to perform corresponding control operation in the cloud equipment interface according to the screen coordinate carried in the target control instruction. The cloud equipment adopts a carried graphics processor to render the interface of the cloud equipment to obtain interface display content, and adopts a carried video encoder to carry out video encoding on the interface display content to generate target video stream data containing the interface display content.
The target video stream data is generated by acquiring the sound and shape data of the anchor and the target control instruction from the target client and controlling the target cloud equipment according to the target control instruction, so that the effect of generating the target video stream data according to the control operation of the anchor on the target cloud equipment at the target client is realized, and a foundation is laid for subsequent stream pushing.
And S102, sending the target video streaming data and the graphic data to the target client and at least one other client except the target client, so that the target client and the other clients can display according to the target video streaming data and the graphic data.
Besides the communication connection with the target client, the server is also in communication connection with at least one other client. The other clients also represent a smart terminal device, and may be, for example, a smart phone, a smart watch, a tablet computer, a notebook computer, or any electronic device with a smart operating system.
In one embodiment, the server sends the target video stream data to the target client, and the target client performs video decoding on the target video stream data and is used for displaying interface display content of the cloud equipment in a screen of the target client. And the server side sends the target video stream data and the audio-visual data of the anchor program to other client sides, and the other client sides carry out video decoding on the target video stream data and analyze the audio-visual data, so that the interface display content of the cloud equipment and the appearance of the anchor program can be displayed on the screens of the other client sides at the same time, and the voice of the anchor program can be played through the loudspeakers of the other client sides.
According to the method, the sound and shape data and the target control instruction of the anchor broadcast are obtained from the target client, the target cloud equipment is controlled according to the target control instruction to generate target video stream data, and then the target video stream data and the sound and shape data are sent to the target client and at least one other client except the target client, so that the target client and the other clients can display according to the target video stream data and the sound and shape data; and moreover, the target video stream data and the audio-visual data of the anchor are displayed simultaneously, so that the live broadcast vitality is improved, and the live broadcast effect is optimized.
On the basis of the above embodiment, after "generating target video stream data" in S101, the method further includes:
and performing associated storage on the target video stream data and the audio data to generate live playback data.
In one embodiment, after the server generates the target video stream data, the server stores the target video stream data and the audio data in association with each other to generate live playback data. When the target client and/or other clients initiate a live playback request to the server, the server sends all target video stream data and audio and video data stored in a related mode to the target client and/or other clients together, and the target client and/or other clients can watch live playback.
The target video stream data and the audio data are stored in an associated mode to generate live playback data, so that a live playback function is provided for a user, the requirement of the user for watching live playback is met, and the user experience is improved.

Wherein the second resolution of the target cloud device represents a display resolution of the cloud device. Since the first coordinate information represents absolute coordinates, and the first resolution of the target client and the second resolution of the target cloud device are not the same in general, it is necessary to determine the second coordinate information corresponding to the first coordinate information in the target cloud device.
In one embodiment, a first ratio of the number of pixels of the first resolution in the X-axis direction to the X-coordinate of the first coordinate information and a second ratio of the number of pixels of the first resolution in the Y-axis direction to the Y-coordinate of the first coordinate information are determined to determine the relative coordinate of the first coordinate information at the first resolution. And determining absolute coordinate information according to the relative coordinates and the second resolution of the target cloud equipment, wherein the absolute coordinate information is used as second coordinate information corresponding to the first coordinate information in the target cloud equipment. And the server controls the cloud equipment to perform corresponding control operation in the cloud equipment interface according to the determined second coordinate information, and generates target video stream data.
And S205, sending the target video streaming data and the graphics data to the target client and at least one other client except the target client, so that the target client and the other clients can display according to the target video streaming data and the graphics data.
According to the method and the device, the control request for the target cloud equipment is obtained from the target client, the target client is subjected to identity verification according to the identity information contained in the control request, and the control authority for the target cloud equipment is issued to the target client under the condition that the identity verification is passed, so that the effect of performing identity verification on the target client is achieved, and the control authority for the target client can be obtained only when the identity verification is passed; the first resolution and the first coordinate information of the target client are obtained from the target control instruction, the second coordinate information corresponding to the first coordinate information in the target cloud equipment is determined according to the first resolution of the target client and the second resolution of the target cloud equipment, the target cloud equipment is controlled according to the second coordinate information, target video stream data are generated, the effect of controlling the target cloud equipment according to the second coordinate information after the relative coordinate conversion is achieved, the accuracy of controlling the target cloud equipment is guaranteed, and misoperation of the target cloud equipment is avoided.
On the basis of the above embodiment, the method further includes:
the method comprises the steps of obtaining a permission issuing request for target cloud equipment from a target client, determining at least one auxiliary client from other clients according to a client identifier contained in the permission issuing request, and issuing control permission for the target cloud equipment to the auxiliary client.
The client identifier includes, but is not limited to, identification information having uniqueness, such as a client device number or a name.
In one implementation, the target client generates a permission issuing request carrying a client identifier, and sends the permission issuing request to the server. The server analyzes the permission issuing request to obtain at least one client identifier, and at least one other client corresponding to the at least one client identifier is used as an auxiliary client, so that the control permission of the target cloud equipment is issued to the auxiliary client, and a user of the auxiliary client can operate and control the target cloud equipment.
By issuing the control authority of the target cloud equipment to the auxiliary client, a user of the auxiliary client can control the target cloud equipment, and the live broadcast interactivity is improved. For example, in a teaching scene, a student can control the target cloud equipment through the auxiliary client to interact with a teacher, such as asking questions or answering questions; for another example, in a game scenario, the spectator may play a game or the like with the game anchor by manipulating the target cloud device through the auxiliary client.
