In the several embodiments provided in the embodiments of the present application, it should be understood that the disclosed apparatus and method may be implemented in other ways, and the apparatus embodiments described below are merely exemplary.
As shown in fig. 1, a first embodiment of a live broadcast interaction method provided in the embodiment of the present application includes:
step S110, displaying a first drawing surface, where the first drawing surface is a live video frame of a main broadcasting end.
For example, before the step of displaying the first drawing surface, the anchor may create and join a microphone channel, and after the joining is successful, the anchor may apply for an permission to open a microphone to the intelligent terminal to which the anchor belongs, and open a local audio capture, where the local audio may be directly acquired by a microphone of the intelligent terminal to which the anchor belongs, or acquired after being connected to the intelligent terminal through an external device, and the anchor may perform special transcoding on the captured audio in real time, and may transmit the transcoded audio signal to the server through a specified channel, where the server may receive the transcoded audio signal, and may also forward the audio signal to other microphone users, so as to implement real-time sharing of audio content.
Before the step of displaying the first drawing surface, the anchor terminal can start screen sharing, after the screen sharing is started, the anchor terminal can apply for opening screen recording permission to the affiliated intelligent terminal and start screen picture capture, wherein the screen picture can be a screen picture of the affiliated intelligent terminal directly collected or a video content collected by connecting an external device with the affiliated intelligent terminal, the anchor terminal can perform special transcoding on the captured screen picture in real time and transmit the transcoded video signal to the server through a specified channel, the server can receive the transcoded video signal and can forward the video signal to other connected-to-the-wheat users, and therefore real-time sharing of screen picture content of the anchor terminal can be achieved.
The user side can apply for joining the connected channel created by the main broadcasting side, the joining process is the same as that of the main broadcasting side, and real-time audio sharing of the user can be achieved.
In a specific implementation, the present embodiment may decode the screen sharing content on the anchor side by adding a surfview in the user side, and draw the screen sharing content on the surfview. It should be noted that the faceview can control the format, size, and rendering position of the rendering.
Step S120, displaying a second drawing surface on the upper layer of the first drawing surface based on the drawing interaction instruction, wherein the second drawing surface is a transparent surface.
The second drawing surface is a transparent surface for image drawing, which is provided on the first drawing surface. The transparent surface can be drawn through a Canvas function on the surface view, and the method for drawing the transparent surface can be calling a Draw Color drawing method in the Canvas function, transmitting a parameter Color.
Step S130, generating drawing information based on the contact interaction event information of the screen area of the second drawing surface.
Illustratively, the contact interaction event information is screen touch event information performed by a user on the screen area of the second drawing surface, and includes a click touch and a slide touch. The handwriting information may be determined according to the contact interaction event information of the screen area of the second drawing surface, and a storage module storing the handwriting information may be established, including a Path module and a Paint module, where the Path module may be configured to store handwriting coordinate information determined according to the contact interaction event information of the screen area of the second drawing surface, and the Paint module may be configured to store information of a handwriting color value and a width determined according to the contact interaction event information of the screen area of the second drawing surface.
According to some embodiments, the generating of the drawing information based on the contact interaction event information of the screen area of the second drawing surface includes:
responding to a drawing starting instruction, and monitoring contact interaction event information of a screen area of the second drawing surface;
and taking all the contact interaction event information as drawing information so as to avoid triggering other application operations through the contact interaction event information.
Illustratively, the drawing start instruction is an instruction for starting to receive contact interaction event information of the screen area of the second drawing surface. A listener can be injected into the Surfaceview, wherein the listener can be used for monitoring contact interaction event information generated by a client user on a screen area of the intelligent terminal, the listener can also inform a system of the intelligent terminal, all the contact interaction event information is used as drawing information, the second drawing surface consumes the contact interaction event information, and the contact interaction event information does not need to be issued to other applications.
The contact interaction event information of the screen area of the second drawing surface is monitored, and all the contact interaction event information is used as drawing information, so that the situation that other applications are started in the operation process of a user, the smoothness and the accuracy of the operation are influenced, and the use feeling of the user is further influenced can be avoided.
According to some embodiments, the drawing start instruction is obtained based on a floating window control, and the floating window control and/or the second drawing surface are displayed on an upper layer of corresponding display contents of all application programs in the intelligent terminal to which the client belongs.
For example, the floating window control may receive the drawing start instruction and receive the contact interaction event information according to the drawing start instruction. The button for opening the graffiti can be arranged as a floating window control, the button for opening the graffiti can be located on the same layer as the second drawing surface or on the upper layer of the second drawing surface, the button for opening the graffiti can be displayed on the upper layer of the corresponding display content of all the application programs in the intelligent terminal to which the user terminal belongs together with the second drawing surface under the condition that the button for opening the graffiti can be located on the same layer as the second drawing surface, and the second drawing surface is displayed on the upper layer of the corresponding display content of all the application programs in the intelligent terminal to which the user terminal belongs under the condition that the button for opening the graffiti is located on the upper layer of the second drawing surface. After clicking the button for opening the graffiti, a color plate can be opened for the user to select colors; the method comprises the steps that a first drawing surface is displayed on a first drawing surface all the time after a main broadcasting end starts screen sharing, contact interaction event information of a screen area of the first drawing surface is monitored by clicking a button for starting graffiti, the second drawing surface is not displayed on the first drawing surface after the main broadcasting end starts screen sharing, the second drawing surface is started through the button for starting graffiti, and contact interaction event information of the screen area of the second drawing surface is monitored.
And displaying the second drawing surface on the first drawing surface without influencing the presentation effect of the video content of the first drawing surface because the second drawing surface is transparent. The anchor end can carry out live game through the mobile end and the PC end, but part of game application does not support the operation of the PC end and can only be operated at the mobile end. Under the condition that the anchor uses the mobile terminal to play live games, full-screen content is usually shared, and therefore other applications need to retreat from the residence background, and therefore the full-screen content needs to be displayed on the upper layers of the corresponding display content of all application programs in the intelligent terminal to which the user side belongs through the floating window control and/or the second drawing surface.
According to some embodiments, the generating of the drawing information based on the contact interaction event information of the screen area of the second drawing surface includes:
determining handwriting coordinate proportion information based on the handwriting coordinate information and the size information of the screen area of the second drawing surface;
and generating the drawing information according to the handwriting coordinate proportion information.
For example, coordinate scale information [ a, b ] of the handwriting may be determined according to coordinate information [ x, y ] of the handwriting and the width and height of the second drawing surface by a = x/m, b = y/n, where m is the width of the second drawing surface and n is the height of the second drawing surface; the width coordinate ratio information c of the handwriting may be determined according to the width coordinate information w of the handwriting and the width of the second drawing surface by c = w/m, and the drawing information may be determined according to the coordinate ratio information of the handwriting and the width coordinate ratio information of the handwriting.
Because the user watches the various live broadcast devices, the screen size and the screen resolution of each device are different, and the handwriting displayed on different intelligent terminals by the same handwriting coordinate information may have differences, so that communication errors can be caused.
According to some embodiments, the generating the drawing information according to the handwriting coordinate ratio information includes:
generating the drawing information according to the percentage data and the color value data;
the displaying the drawing information on the live video picture through the second drawing surface includes:
and sending the drawing information to a server so that the server sends the drawing information to other clients so as to display the drawing information on the live video picture through the second drawing surface in other clients.
For example, the color value data of the color may be determined according to the color selected by the user in a case where the user opens the color panel. For example, under the condition of drawing by the user side, the intelligent terminal to which the user belongs can transcode drawing information into a byte array, the byte array is sent to the server through a special channel at the frequency of once every 30 milliseconds, the server can send the byte array to the anchor side, handwriting is restored on the second drawing surface of the anchor side, screen content sharing of other users is achieved through the screen sharing function of the anchor side, the byte array can also be sent to other clients through the server, the byte array is directly restored by the other clients, and the handwriting is restored on the second drawing surface of the user side.
The drawing information is generated according to the percentage data and the color value data, the drawing information is sent to other clients through the server, the drawing information is displayed on the live video picture through the second drawing surface in other clients, self-adaption of a screen can be carried out on handwriting information according to different screen sizes and resolution ratios of different users, the handwriting information is displayed according to the color value data, the accuracy of color presentation can be guaranteed, the occurrence of color difference is avoided, and the accuracy of interactive information can be guaranteed.
Step S140 is displaying the drawing information on the live video frame through the second drawing surface.
Illustratively, in a case that a corresponding instruction of the prompt information is received, the drawing information may be extracted from the Path module and the Paint module, a Draw Path handwriting drawing method in a Canvas function may be called, and the drawing information is transferred to a Canvas, so that the drawing information is presented on the second drawing surface.
According to some embodiments, in the case of receiving drawing information generated by other clients sent by a server, prompt information is generated;
and displaying the drawing information on the live video picture through the second drawing surface when the response instruction of the prompt information is received.
For example, the user side may actively send information requesting interaction to the anchor side, or the anchor side may actively authorize the user side to perform interactive drawing. And under the condition that the anchor receives the information of requesting interaction, the server can generate the information of requesting interaction into prompt information to prompt the anchor that other users need to interact at the moment. The anchor terminal can receive the prompt information sent by the server, and when the anchor receives the prompt information and agrees to perform interaction, the user side performs drawing on the screen area to which the audience client belongs through a second drawing surface of the user, and the server sends the drawing information of the user side to the anchor terminal. The anchor terminal can restore the drawing information on the anchor second drawing surface and display the anchor second drawing surface on the upper layer of the live video picture.
According to some embodiments, the live video frame is associated with at least two second drawing surfaces, and the drawing information is generated together based on the contact interaction event information of the screen areas to which the at least two second drawing surfaces belong.
For example, the anchor end may assign the drawing authority to at least two viewer clients only, and the plurality of viewer clients assigned with the drawing authority perform drawing together.
Therefore, the problem encountered in the live broadcasting of the anchor terminal can be solved by identifying the multiple audience clients in the live broadcasting interface, and the problem solving efficiency is improved.
According to some embodiments, the second drawing surface comprises a main drawing surface associated with the main side client and a user drawing surface associated with the viewer client, and the drawing information is generated by the contact interaction event information of the screen areas of the main drawing surface and the at least one user drawing surface.
Illustratively, a live video frame of a anchor may be displayed in a plurality of clients including the anchor and viewer clients. The anchor end can give the drawing authority to at least one audience client under the condition of ensuring that the anchor end has the drawing authority, and the anchor end and the audience client draw together. In the case where the anchor side gives the drawing authority to one viewer client a, then the viewer client a and the anchor side may perform the drawing operation on the respective second drawing surfaces. For example, as shown in fig. 2, the anchor does not know how to set the skill of the game character, and gives the drawing authority to the anchor client and the spectator client a, the user client may draw a circle at a channel entry icon 1 entering the skill interface for setting the game character in the live interface through the second drawing surface, and the anchor may draw a circle at an icon 2 if the anchor considers that the channel entry entering the skill interface for setting the game character is correct and is icon 2. The method and the system can realize real-time interaction between the anchor terminal and the user terminal, and avoid the problems that the communication time is long, the communication efficiency is low, the live broadcast process is influenced and the like because only the anchor terminal or the audience client terminal is allowed to independently draw.
For example, the anchor terminal may give the drawing authority to two or more viewer clients under the condition that the anchor terminal is guaranteed to own the drawing authority, and a plurality of viewer clients and the anchor terminal may draw together. The time for the same problem to be communicated with different users independently can be saved, and the interaction degree and the communication efficiency of the anchor terminal and the user terminal are further improved.
Therefore, when the anchor terminal and the audience client terminal communicate problems, interactivity is more diversified, and particularly when the live interface display content needs to be combined for communication, communication efficiency is higher, and the problem solving speed is higher.
According to some embodiments, the displaying the drawing information on the live video frame through the second drawing surface includes:
under the condition that the client is a spectator client, acquiring first trace coordinate information corresponding to the drawing information existing in the received live screen interface;
acquiring second handwriting coordinate information which is recorded on the second drawing surface of the audience client and is associated with the first handwriting coordinate information;
and under the condition that the first handwriting coordinate information is not matched with the second handwriting coordinate information, modifying the first handwriting coordinate information and/or the second handwriting coordinate information so that a handwriting picture corresponding to the second handwriting coordinate information covers the handwriting picture corresponding to the first handwriting coordinate information.
Illustratively, the first handwriting coordinate information is drawing information of the audience client received by the anchor terminal, and the drawing information is sent to the server, so that the server sends the drawing information to other clients, and handwriting information of a live video picture is displayed in the audience client. The second handwriting coordinate information is note coordinate information drawn by the user on a second drawing surface of the user of the viewer client. The handwriting coordinate information corresponding to the drawing information of the live screen interface can be acquired, and the handwriting information associated with the first handwriting coordinate information on the second drawing surface of the user of the audience client can be acquired and used as the second handwriting coordinate information. Under the condition that the first handwriting coordinate information is not matched with the second handwriting coordinate information, the second handwriting coordinate information can be modified according to the first handwriting coordinate information, the first handwriting coordinate information can be modified according to the second handwriting coordinate information, and the first handwriting coordinate information and the second handwriting coordinate information can be synchronously modified according to the first handwriting coordinate information and the second handwriting coordinate information.

the server is further configured to receive the second video stream, and forward the second video stream to a main broadcaster and other viewer clients.
Specifically, the embodiment can be applied to a scene where the anchor and the user interact with each other, for example, the anchor plays a game live broadcast, and draws a track (i.e., generated drawing information) on a live video picture displayed by the anchor; a user watches the live video picture of the anchor in the live broadcasting room of the anchor, the user draws tracks on the live video picture played by the audience client, and the tracks drawn by the anchor and the user on the same live video picture are synchronously rendered by channel transmission.
Further, a second embodiment of a live broadcast interaction method provided in the embodiments of the present application, as shown in fig. 4, includes:
in this embodiment, after the step of displaying the drawing information on the live video frame through the second drawing surface in the step S140, the method further includes:
step S410: and determining corresponding target content from the live video picture according to the handwriting coordinate information.
It can be understood that, before the drawing information is generated for the first time, the live interactive device 300 captures the handwriting coordinate information generated when the anchor end/audience client user touches the mobile phone screen, where the handwriting coordinate information is the coordinate a of the drawing information generated for the first time, as shown in fig. 5a, the anchor end user draws a circle, which is the drawing information on the second drawing surface, to the character 1 in the live video picture at the position of the coordinate a on the terminal screen, where the character 1 is the target content on the first drawing surface (live video picture);
step S420: when the current coordinate information of the target content in the first drawing surface is detected to be inconsistent with the handwriting coordinate information on the second drawing surface, adjusting the handwriting coordinate information to the coordinate position of the current coordinate information on the second drawing surface for displaying, so that the current note coordinate of the drawing information is synchronous with the current coordinate position of the target content.
It can be understood that the target content (character 1) in the live video picture moves continuously in the live video picture, the live interactive device 300 captures the current coordinate information of the target content (character 1) on the screen in real time, and compares the current coordinate information of the target content (character 1) with the handwriting coordinate information of the user on the second drawing surface (i.e. the coordinate a of the circle drawn for the character 1 in fig. 5 a) to determine whether the target content in the live video picture moves, and if the comparison result shows that the current coordinate information of the character 1 is different from the coordinate a of the handwriting coordinate information, it is determined that the target content (character 1) in the live video picture moves, as shown in fig. 5B, that is, the current coordinate information of the character 1 moves to the coordinate B; the live interactive device 300 transfers the current coordinates of the target content (character 1) moving in the screen to a second drawing surface in real time, adjusts the current note coordinates of the drawing information (circle drawn by the user for the character 1) from the original coordinates a to the coordinate position of coordinates B in the second drawing surface (as shown in fig. 5 c), encodes the drawing information with the adjusted note coordinates in the second drawing surface and the live video frame to form a third video stream, and sends the third video stream to the server, and the server broadcasts the third video stream to other viewer clients in the live room, so that all viewers in the live room can see the picture effect that the note coordinates of the drawing information are synchronized with the current coordinate position of the target content after the target content moves in the screen, and thus, after the main broadcast end/viewer client marks the target content in the live video frame on the screen, the live broadcast end and the live broadcast mark of the target content can synchronize with the moving track of the target content in the live video frame even if the target content moves in the live broadcast frame.
