Description


[0001] This application claims priority to Chinese Patent Application No. 201711482284.2, filed on December 29, 2017 and entitled "METHOD AND APPARATUS FOR LIVE STREAMING", the entire contents of which are incorporated herein by reference.

TECHNICAL FIELD



[0002] The present disclosure relates to the field of Internet technologies, and in particular, relates to a method and apparatus for live streaming.

BACKGROUND



[0003] With the development of the Internet technologies, mobile phones, computers and other terminals have been widely used. Accordingly, the types of applications on the terminals are increasing, and functions of the applications are becoming more and more abundant. Among these applications, a network-based live streaming application is a very common application.

[0004] For example, in live streaming of a song, an existing live streaming mode is that a host opens an application on a device such as a mobile phone or a computer and selects a song to be sung; the application plays an accompaniment of the song; and the host sings along with the accompaniment. In this process, the application may perform video collection and audio collection on the host, and sends the collected video and human audio as well as the played accompaniment audio to a streaming media server in real time. By the streaming media server, a user may watch a live stream through the application on the device such as the mobile phone or the computer. If the host uses different devices, the application used by the host may send a video stream in a horizontal screen mode (a display mode in which width is greater than height) or a video stream in a vertical screen mode (a display mode in which the width is less than height) to the streaming media server.

[0005] However, in a process of implementing the present disclosure, the inventor finds that the related art at least has the following problems.

[0006] When the video stream send by the host application is in the horizontal screen mode, the application on the mobile phone of the user may present the video stream to the user in a half-screen manner, such that the experience of the user who watches the live stream by using the mobile phone is poor. When the video stream send by the host application is in the vertical screen mode, the application on the computer of the user may present the video stream to the user in the vertical screen mode, such that the experience of the user who watches the live stream by using the computer is poor. Thus, a display ratio of the live streaming video on the screen is not suitable for the screen for displaying the live streaming video, thereby wasting a display space of the screen for displaying the live streaming video.

[0039] The specific embodiments of the present disclosure have been shown by the above drawings, and are described in more detail hereinafter. These drawings and textual descriptions are not intended to limit the concept scope of the present disclosure through any means, but are used to illustrate the concepts of the present disclosure to those skilled in the art by reference to the specific embodiments.

DETAILED DESCRIPTION



[0040] For clearer descriptions of the objectives, technical solutions and advantages of the present disclosure, the embodiments of the present disclosure are described in detail hereinafter with reference to the drawings.

[0041] The embodiments of the present disclosure provide a method and an apparatus for live streaming. The method may be implemented by a server and a terminal, and the terminal may be a terminal capable of performing live streaming.

[0042] The server may include components such as a processor, a memory and a transceiver. The processor may be a central processing unit (CPU) or the like, and may be configured to determine a terminal having the same video mode as the first terminal, and a terminal having the same video mode as the second terminal. The memory may be an random access memory (RAM), a flash or the like, and may be configured to store received data, data required in processing, data generated in the processing, and the like; and the data may be, such as, a corresponding relationship between device identifiers and video modes, and device identifiers of the first terminal and the second terminal. The transceiver may be configured to perform data transmission with the terminal or another server, for example, receiving first live streaming image data and live streaming audio data sent by the first terminal and the first device identifier of the first terminal; receiving second live streaming image data and the live streaming audio data sent by the second terminal and the second device identifier of the second terminal; receiving a live streaming view request sent by a terminal of a viewer; and sending the live streaming image data and the live streaming audio data to the terminal of the viewer. The transceiver may include an antenna, a matching circuit, a modem, and the like.

[0043] The terminal may include components such as a processor, a memory, a transceiver, a screen, an image detecting component, an audio output component and an audio input component. The processor may be a CPU or the like, and may be configured to control a screen to display a prompt box for prompt whether to set the second terminal as a pairing terminal, and to execute a confirmation instruction of the prompt box, and the like. The memory may be a RAM, a flash or the like, and may be configured to store received data, data required in processing, data generated in the processing, and the like; and the data may be, such as, a live streaming start message, a live streaming audio data, and a device identifier. The transceiver may be configured to perform data transmission with another device, for example, receiving a pairing request, receiving a pairing response message, sending the live streaming start message, sending live streaming audio data and live streaming image data to the server, and the like. The transceiver may include an antenna, a matching circuit, a modem, and the like. The screen may be a touch screen and may be configured to display the received first data and the like. The image detecting component may be a camera or the like. The audio output component may be a speaker, an earphone, or the like. The audio input component may be a microphone, or the like.

[0044] As shown in FIG. 1, a processing flow of the method for live streaming may include the following steps.

[0045] In step 101, a first terminal broadcasts a pairing request; a second terminal receives the pairing request broadcast by the first terminal, and then sends a pairing response message to the first terminal. When receiving the pairing response message sent by the second terminal, the first terminal displays a prompt box for prompting whether to set the second terminal as the pairing terminal; and when receiving a confirmation instruction sent by the prompt box, the first terminal records the second terminal as the pairing terminal to which the live streaming audio data is sent.

[0046] In an implementation, a host may use two terminals for live streaming simultaneously during live streaming, wherein video modes of screens of the two terminals are different. For example, the first terminal may be a computer, such that the video mode of the first terminal is a horizontal screen mode; and the second terminal may be a smart phone, such that the video mode of the second terminal is a vertical screen mode. Prior to the live streaming, the host needs to pair the two terminals, such that the first terminal may send the live streaming audio data to the second terminal.

[0047] The first terminal creates a device pairing socket and sets a broadcast attribute for the socket. The first terminal sends a pairing request to N network addresses by using the pairing socket. The value range of N may be [5, 10], and the IP address of these network addresses may be the broadcast address 255.255.255.255. In this way, all terminals in this local area network may receive the pairing request broadcast by the first terminal through the broadcast address.

[0048] The second terminal creates N pairing UDP (User Datagram Protocol) sockets, wherein N herein is the same as N described in the "the first terminal sends the pairing request to the N network addresses" to avoid a condition that the second terminal cannot receive the pairing request by using the pairing UDP sockets caused by a conflict between a bound network address of a part of the sockets and a bound network address of a socket of another program on the second terminal, and may have the value range of [5, 10]. The second terminal sets broadcast attributes for the N pairing UDP sockets, and binds network addresses A1, A2, ... and AN to the N pairing UDP sockets, respectively. In order to improve receiving efficiency of the second terminal in receiving the pairing request, IP addresses corresponding to the network addresses may be set to a host computer arbitrary IP address 0.0.0.0. The port IDs P1, P2, ... and PN corresponding to the N pairing UDP sockets are set to preset port ID values. For example, P1 may be 8181, and P2 may be greater than P1 by 1, that is, P2 is 8182. Similarly, the values of the remaining port IDs P3, P4...are set.

[0049] After setting the N pairing UDP sockets, the second terminal receives the pairing request sent by the first terminal on one of the pairing UDP sockets, records a source network address as Asource, and closes other UDP sockets. The second terminal may obtain its own device information. For example, the device information may be a device name, a phone number or the like. The information and the port number corresponding to the UDP socket that has received the pairing request are encapsulated into a pairing response message. The second terminal sends the pairing response message to a device whose network address is Asource (i.e., the first terminal) through the UDP socket that has received the pairing request. The second terminal may also only encapsulate the port number into the pairing response message, and sends the pairing response message to the device whose network address is Asource (i.e., the first terminal) through the UDP socket that has received the pairing request, which is not limited in the present disclosure.

[0050] When the first terminal receives the pairing response message sent by the second terminal, a prompt box may be popped up on the screen. As shown in FIG. 2, the prompt box may display the device information of the second terminal, and asks the host whether to set the second terminal as the pairing terminal. Alternatively, the prompt box may directly display whether to set the second terminal as the pairing terminal. If the host confirms that the second terminal is the terminal that he/she wants to set, he/she may click the confirmation option in the prompt box. After receiving the confirmation instruction, the first terminal records the second terminal as the pairing terminal to which the live streaming audio data is sent. Heretoforth, the first terminal and the second terminal are successfully paired.

[0051] It should be noted that if the first terminal does not receive the pairing response message sent by the second terminal, the first terminal continues to broadcast the pairing request. When the number of times that the first terminal broadcasts the pairing request exceeds a preset number of times, but the first terminal has not received the pairing response message sent by the second terminal, the first terminal displays a prompt box showing that the second terminal cannot be found, displays a possible reason why the second terminal cannot be found, such as that the second terminal does not install an application related to live streaming, to the host, and additionally, displays a download address or a two-dimensional code of this application.

[0052] It should be noted that, in this process, the first terminal also needs to create an audio sending socket; and the second terminal also needs to create an audio receiving socket, and binds the audio receiving socket to the local IP address and the port P1. If the binding fails, the audio receiving socket is bound to the local IP address and the port P2, and the operation is continued in the same manner till the binding is successful. This is a preparation for the first terminal to send the live streaming audio data to the second terminal, and details are not repeated herein.

[0053] In step 102, when receiving the live streaming start instruction, the first terminal performs live streaming start processing, and sends a live streaming start message to the second terminal, wherein the live streaming start message carries link information of the server, and the link information includes address information and a live streaming room identifier.

[0054] In an implementation, after the first terminal and the second terminal are successfully paired through the above step 101, the host may click a live streaming start option on the first terminal to perform live streaming. When receiving the live streaming start instruction input by the host, the first terminal performs the live streaming start processing, and sends the live streaming start message to the second terminal to instruct the second terminal to start the live streaming synchronously. The live streaming start message carries the link information of the server. The link information includes the address information and the live streaming room identifier. The address information is intended to instruct the second terminal to establish a network connection with the server. The live streaming room identifier is intended to instruct the second terminal to perform live streaming with the first terminal in the same live streaming room.

[0055] In step 103, the first terminal collects live streaming audio data and first live streaming image data in a live streaming process.

[0056] In an implementation, the first terminal collects the live streaming audio data and the first live streaming image data in the live streaming process. The collected live streaming audio data may be human audio, namely, the voice of the host, or may be the sound of an instrument played by the host, or the like. The collected live streaming audio data may also be audio combined by the human audio and the accompaniment audio; and the accompaniment audio is acquired and played by the first terminal.

[0057] In step 104, the second terminal receives the live streaming start message sent by the first terminal, wherein the live streaming start message carries the link information of the server; and the link information includes the address information and the live streaming room identifier. The second terminal performs the live streaming start processing according to the link information of the server.

[0058] In an implementation, after the first terminal sends a live streaming start message to the second terminal in the above step 102, the second terminal receives the live streaming start message sent by the first terminal. The live streaming start message carries the link information of the server; and the link information includes the address information and the live streaming room identifier. The second terminal determines whether the live streaming start message is received for the first time. If the live streaming start message is received for the first time, the second terminal establishes a network connection with the server according to the address information; and after the network connection is successfully established, the second terminal is triggered to start the live streaming. If the live streaming start message is not received for the first time, the message is ignored.

[0059] It should be noted that the live streaming start message further carries information such as a sampling rate, the number of sound channels, and the number of sampling bits of the live streaming audio data collected by the first terminal. The second terminal creates an audio code rate unit according to the sampling rate, the number of the sound channels, and the number of sampling bits to prepare for receiving the live streaming audio data sent by the first terminal.

[0060] In step 105, the second terminal collects second live streaming image data in a live streaming process.

[0061] The first terminal and the second terminal have different video modes, wherein the video modes include a horizontal screen mode and a vertical screen mode.

[0062] In an implementation, the second terminal collects the second live streaming image data in the live streaming process.

[0063] It should be noted that the first terminal and the second terminal have different video modes, and the video modes include the horizontal screen mode and the vertical screen mode. For example, the first terminal is a computer, and has a video mode in the horizontal screen mode; and the second terminal may be a smart phone, and has a video mode in the vertical screen mode. In this way, it may ensure that the two terminals collect different modes of videos, such that viewers who watch the live stream through the terminals in the different video modes may watch videos suitable for the modes of the used terminals, thereby improving the watching experience of the viewers.

[0064] In step 106, the first terminal sends the live streaming audio data and the first live streaming image data to the server synchronously, and sends a first device identifier of the first terminal to the server.

[0065] In an implementation, as shown in FIG. 3, the first terminal performs pre-processing, encoding and encapsulation on each frame of the collected live streaming audio data and first live streaming image data to generate a video stream in the live streaming process, and sends the video stream to the server in real time. Meanwhile, the first device identifier of the first terminal is sent to the server, such that the server may conveniently determine a video mode of the first live streaming image data according to the first device identifier.

[0066] In step 107, the first terminal sends the live streaming audio data to the second terminal, wherein the first terminal and the second terminal have different video modes, and the video modes include a horizontal screen mode and a vertical screen mode.

[0067] In an implementation, as shown in FIG. 3, every time when collecting one frame of the live streaming audio data, the first terminal encapsulates the live streaming audio data and the first live streaming image data, and sends the encapsulated live streaming audio data and first live streaming image data to the server. At the same time, the first terminal sends the live streaming audio data to the second terminal in real time through the audio sending socket created in the above step 101.

[0068] It should be noted that when collecting the live streaming audio data, the first terminal timely records a collected audio frame number AF1. That is, in the collection process, every time when collecting one frame of the live streaming audio data, the first terminal adds 1 to the collected audio frame number AF1, and sends the audio frame number AF1 and the live streaming audio data to the second terminal.

[0069] In step 108, the second terminal receives the live streaming audio data sent by the first terminal, wherein the first terminal and the second terminal have different video modes, and the video modes include a horizontal screen mode and a vertical screen mode.

[0070] In an implementation, the second terminal receives the live streaming audio data sent by the first terminal by using the audio receiving socket created in the above step 101.

[0071] It should be noted that when receiving the live streaming audio data sent by the first terminal, the second terminal timely records the number of the received audio frames, and sets the received audio frame number as AF2. When the second terminal receives one frame of the live streaming audio data sent by the first terminal, 1 is added to AF2.

[0072] Optionally, the second terminal counts a transmission packet loss rate of the live streaming audio data sent by the first terminal. The second terminal sends the transmission packet loss rate to the first terminal.

[0073] In an implementation, based on AF1 and AF2 obtained in the above steps, the transmission packet loss rate of the live streaming audio data sent by the first terminal may be calculated according to the following equation:



[0074] Here, Packet_loss_rate represents the transmission packet loss rate; AF1 represents the number of the audio frames sent from the first terminal to the second terminal; and AF2 represents the number of the audio frames received by the second terminal.

[0075] After obtaining the transmission packet loss rate, the second terminal sends the transmission packet loss rate to the first terminal.

[0076] It should be noted that the second terminal may send the transmission packet loss rate to the first terminal according to a preset period, such as every 1 s; or each time when receiving 20 frames of audio, the second terminal sends the transmission packet loss rate to the first terminal, which is not limited in the present disclosure.

[0077] Optionally, the first terminal receives the transmission packet loss rate of the live streaming audio data sent by the second terminal; and if the transmission packet loss rate is greater than a preset threshold, the first terminal stops sending the live streaming audio data to the second terminal.

[0078] In an implementation, after the second terminal sends the transmission packet loss rate to the first terminal, the first terminal receives the transmission packet loss rate, and compares the received transmission packet loss rate with the preset threshold. If the transmission packet loss rate is greater than the preset threshold, it indicates that more audio frames are lost in a transmission process, which may result in poor performance of the audio received by the second terminal. Therefore, in this case, the host is reminded of an abnormal connection between the first terminal and the second terminal; and the first terminal stops sending the live streaming audio data to the second terminal, and stops the live streaming at the same time. In this way, the host may be timely reminded to solve the connection problem between the first terminal and the second terminal.

[0079] In addition, if a duration in which the first terminal has not received the transmission packet loss rate of the live streaming audio data sent by the second terminal exceeds a preset duration, it indicates that there may be a problem in the transmission between the first terminal and the second terminal. As a result, the second terminal cannot send the transmission loss rate to the first terminal. In this case, the host is reminded of the abnormal connection between the first terminal and the second terminal; and it is required to check the network and stop the live streaming of the first terminal.

[0080] In step 109, the second terminal sends the second live streaming image data and the live streaming audio data to the server synchronously, as shown in FIG. 3, and sends the second device identifier of the second terminal to the server.

[0081] In an implementation, the second terminal performs pre-processing, encoding, and encapsulation on the collected second live streaming image data and the received live streaming audio data to form a video stream, and sends the video stream to the server in real time. At the same time, the second terminal sends the second device identifier of the second terminal to the server.

[0082] Optionally, the above live streaming start message further carries a sampling rate of the live streaming audio data. In order to prevent delay of the received audio and the collected image, the second terminal adjusts a timestamp of the received audio such that a timestamp of the audio frame is the same as that of a corresponding image frame. The corresponding processing may be as follows: the second terminal determines a frame duration of each audio frame of the live streaming audio data according to the sampling rate; each time when receiving one audio frame of the live streaming audio data, the second terminal adjusts a timestamp of the received audio frame to a time obtained by subtracting the frame duration from a current time; and the second terminal synchronously sends live streaming audio data obtained after the timestamps are adjusted as well as the second live streaming image data to the server.

[0083] In an implementation, the second terminal may determine the frame duration of each of the audio frames of the live streaming audio data according to the sampling rate of the live streaming audio data carried in the live streaming start message. Then, according to a gettimeofday function (a function for obtaining a precise current time), a current time of the second terminal is obtained and converted into a time in milliseconds. A time obtained by subtracting the frame duration of each of the audio frames from the current time is determined as a new timestamp of the received audio frame.

[0084] In addition, in the above step, when the second terminal collects the second live streaming image data of each frame, the current time in milliseconds of the second terminal is determined as a timestamp of a currently collected image frame through the gettimeofday function.

[0085] Then, the second terminal synchronously sends the live streaming audio data obtained after the timestamps are adjusted as well as the second live streaming image data to the server.

[0086] In step 110, the server receives the first live streaming image data, the live streaming audio data, and the first device identifier of the first terminal sent by the first terminal, and receives the second live streaming image data, the live streaming audio data and the second device identifier of the second terminal sent by the second terminal.

[0087] In step 111, the server determines a terminal having the same video mode as the first terminal and a terminal having the same video mode as the second terminal based on the first device identifier, the second device identifier, and device identifiers of other terminals in a live streaming room corresponding to the first terminal.

[0088] Optionally, the terminal having the same video mode as the first terminal and the terminal having the same video mode as the second terminal may be determined according to the pre-established device identifier groups. The processing of the above step 111 may be as follows: a terminal whose device identifier belongs to the same device identifier group as the first device identifier and a terminal whose device identifier belongs to the same device identifier group as the second device identifier are determined from the other terminals in the live streaming room based on the pre-established device identifier groups.

[0089] The device identifier groups include a first device identifier group and a second device identifier group; a video mode of the terminal corresponding to the device identifier in the first device identifier group is a horizontal screen mode; and a video mode of the terminal corresponding to the device identifier in the second device identifier group is a vertical screen mode.

[0090] In an implementation, the server may pre-establish the first device identifier group and the second device identifier group. The video mode of the terminal corresponding to the device identifier in the first device identifier group is a horizontal screen mode; and the video mode of the terminal corresponding to the device identifier in the second device identifier group is a vertical screen mode. When a terminal of another viewer in the live streaming room initiates a live streaming view request to the server, the live streaming view request carries a device identifier of the terminal of this viewer. The server determines whether the device identifier of the terminal of the viewer belongs to the first device identifier group or the second device identifier group, and then determines a terminal whose device identifier belongs to the same device identifier group as the first device identifier and a terminal whose device identifier belongs to the same device identifier group as the second device identifier.

[0091] A correspondence between the device identifiers and the device identifier groups may be as shown in Table 1 below.
Table 1
Device identifierVideo mode
Android First device identifier group
iOS
PC Web Second device identifier group


[0092] When the viewer wants to watch a live stream through the terminal, the viewer may click a live streaming view option. The terminal of the viewer sends a live streaming view request to the server, wherein the live streaming view request carries the device identifier of the terminal of the viewer. After receiving the live streaming view request, the server determines a video mode corresponding to the terminal of the viewer according to the device identifier of the terminal of the viewer, and then determines the video mode corresponding to the terminal of the viewer is the same as the video mode of the first terminal or the second terminal.

[0093] In step 112, the server sends the first live streaming image data and the live streaming audio data sent by the first terminal to the terminal having the same video mode as the first terminal, and sends the second live streaming image data and the live streaming audio data sent by the second terminal to the terminal having the same video mode as the second terminal.

[0094] Optionally, after the terminal whose device identifier belongs to the same device identifier group as the first device identifier and the terminal whose device identifier belongs to the same device identifier group as the second device identifier are determined, the processing of the above step 112 may be as follows. The server sends the first live streaming image data and the live streaming audio data sent by the first terminal to the terminal whose device identifier belongs to the same device identifier group as the first device identifier, and sends the second live streaming image data and the live streaming audio data sent by the second terminal to the terminal whose device identifier belongs to the same device identifier group as the second device identifier.

[0095] In an implementation, as shown in FIG. 4, after determining the terminal whose device identifier belongs to the same device identifier group as the first device identifier, the server sends the first live streaming image data and the live streaming audio data sent from the first terminal to the server to the terminal. After determining the terminal whose device identifier belongs to the same device identifier group as the second device identifier, the server sends the second live streaming image data and the live streaming audio data sent from the second terminal to the server to the terminal. In this way, on the terminal in the vertical screen mode, the live streaming video is displayed in the vertical screen mode; and on the terminal in the horizontal screen mode, the live streaming video is displayed in the horizontal screen mode. Thus, the user could watch a live streaming video with a suitable display ratio no matter which video mode that the terminal adopts. Therefore, the experience of the viewer watching the live stream is improved.

[0096] In the embodiment of the present disclosure, the first terminal collects the live streaming audio data and the first live streaming image data in the live streaming process, sends the live streaming audio data and the first live streaming image data to the server, sends the first device identifier of the first terminal to the server, and sends the live streaming audio data to the second terminal; and the second terminal collects the second live streaming image data, sends the second live streaming image data and the live streaming audio data to the server, and sends the second device identifier of the second terminal to the server. In this way, the host could simultaneously send the video stream in the horizontal screen mode and the video stream in the vertical screen mode. Thus, the user could watch a live streaming video with a display ratio suitable for a terminal screen on the terminal screen no matter whether the user watches the live streaming video on the terminal in a horizontal screen mode or a vertical screen mode. Therefore, a display space of the screen is utilized reasonably.

When it is determined that the identify of the user is trustable, the processor 1401 authorizes the user to perform related sensitive operations, wherein the sensitive operations include unlocking the screen, checking encrypted information, downloading software, paying and modifying settings and the like. The fingerprint sensor 1414 may be arranged on a front face a back face or a side face of the terminal 1400. When the terminal 1400 is provided with a physical key or a manufacturer's logo, the fingerprint sensor 1414 may be integrated with the physical key or the manufacturer's logo.

[0137] The optical sensor 1415 is configured to acquire the intensity of ambient light. In one embodiment, the processor 1401 may control a display luminance of the touch display screen 1405 based on the intensity of ambient light acquired by the optical sensor 1415. Specifically, when the intensity of ambient light is high, the display luminance of the touch display screen 1405 is up-shifted; and when the intensity of ambient light is low, the display luminance of the touch display screen 1405 is down-shifted. In another embodiment, the processor 1401 may further dynamically adjust photographing parameters of the camera assembly 1406 based on the intensity of ambient light acquired by the optical sensor.

[0138] The proximity sensor 1416, also referred to as a distance sensor, is generally arranged on the front panel of the terminal 1400. The proximity sensor 1416 is configured to acquire a distance between the user and the front face of the terminal 1400. In one embodiment, when the proximity sensor 1416 detects that the distance between the user and the front face of the terminal 1400 gradually decreases, the processor 1401 controls the touch display screen 1405 to switch from an active state to a rest state; and when the proximity sensor 1416 detects that the distance between the user and the front face of the terminal 1400 gradually increases, the processor 1401 controls the touch display screen 1405 to switch from the rest state to the active state.

The terminal may include more components over those illustrated in FIG. 14, or combinations of some components, or employ different component deployments.

[0140] FIG. 15 is a schematic structural diagram of a server according to an embodiment of the present disclosure. The server 1500 may vary greatly depending on different configurations or performance, and may include one or more central processing units (CPUs) 1522 (e.g., one or more processors) and a memory 1532, one or more storage media 1530 (e.g., one or one mass storage devices) for storing an application 1542 or data 1544. The memory 1532 and the storage medium 1530 may be transient storage media or persistent storage media. The program stored in the storage medium 1530 may include one or more modules (not shown in this Figure), each of which may include a series of instruction operations performed by the server. Furthermore, the CPU 1522 may be communicated with the storage medium 1530, and the series of instruction operations in the storage medium 1530 may be performed on the server 1500.

[0141] The server 1500 may further include one or more power sources 1526, one or more wired or wireless network interfaces 1550, one or more input/output interfaces 1558, one or more keyboards 1556, and/or one or more operating systems 1541, such as Windows ServerTM, Mac OS XTM, UnixTM, LinuxTM, and FreeBSDTM.

[0142] The server 1500 may include a memory, and one or more programs, wherein the one or more programs are stored in the memory and are configured to be executed by one or more processors to perform the method for live streaming described in each of the above embodiments.

[0143] In the embodiments of the present disclosure, the first terminal collects the live streaming audio data and the first live streaming image data in the live streaming process, sends the live streaming audio data and the first live streaming image data to the server, sends the first device identifier of the first terminal to the server, and sends the live streaming audio data to the second terminal, wherein video modes of the first and second terminals are different, and include a horizontal screen mode or a vertical screen mode. The second terminal collects the second live streaming image data, sends the second live streaming image data and the live streaming audio data to the server, and sends the second device identifier of the second terminal to the server. In this way, the host could simultaneously send the video stream in the horizontal screen mode and the video stream in the vertical screen mode. Thus, the user could watch a live streaming video with a display ratio suitable for a terminal screen on the terminal screen no matter if the user watches the live streaming video on the terminal in the horizontal screen mode or the vertical screen mode. Therefore, a display space of the screen is utilized reasonably.
