The field capture device 101 completes capture of multiple video streams, which are then transmitted by the field terminal device 102 to the cloud device 200. The cloud director 201 in the cloud device 200 selects one of the video streams as a live stream, and outputs the live stream to the user device 300. The detailed implementation of each step is described in the following method examples.

Wherein the video stream is used for transmitting video data, and the live stream is a video stream output as a live broadcast.

There may be multiple field acquisition devices 101 in the terminal device 100, and multiple field acquisition devices 101 achieve shooting at multiple angles, so as to obtain video pictures at multiple angles, and form multiple video streams.

Each terminal device 100 finishes the acquisition and uploading of at least one video stream, and the cloud device 200 receives the video streams uploaded by the at least two terminal devices 100, so as to obtain multiple video streams. The cloud device 200 selects one of the multiple video streams as a live stream, and outputs the live stream to the user device 300.

Fig. 2A illustrates a video live method according to an exemplary embodiment, which includes the following steps, as shown in fig. 2A.

In step S11, the cloud device receives multiple video streams sent by at least one terminal device, where the multiple video streams are used to transmit video data collected from a live broadcast.

In this step, the cloud device may receive multiple video streams sent by one terminal device; or multiple video streams sent by two or more terminal devices may be received, in which case, each terminal device sends one, two, or multiple video streams, so as to obtain multiple video streams.

In step S12, one video stream is selected from the multiple video streams as a live stream.

And the cloud device selects one path from the received multiple paths of video streams and outputs the selected path to the user equipment.

In step S13, the live stream is output.

I.e. outputting the live stream to the user device.

Fig. 2B illustrates a video live method according to an exemplary embodiment, which includes the following steps, as shown in fig. 2B.

In step S21, the terminal device obtains at least one video stream collected in the live broadcast.

In step S22, the at least one video stream is transmitted to the cloud device, so that the cloud device selects one video stream from multiple video streams as a live stream for output, where the multiple video streams include the at least one video stream.

Fig. 2C illustrates a video live method according to an exemplary embodiment, which includes the following steps, as shown in fig. 2C.

In step S31, the terminal device obtains at least one video stream collected on site.

The terminal device is a device arranged on a live broadcast site, and generally comprises a site acquisition device and a site terminal device.

In an embodiment of the present disclosure, a terminal device obtains a video stream acquired in a field, including:

the method comprises the steps that a field acquisition device acquires a field picture and a field audio to form at least one path of video stream; and the field terminal equipment receives at least one path of video stream transmitted by the field acquisition equipment. The video stream collected by the field collection device is at least one path, and when the collected video stream is more than one path, the video streams are obtained by shooting a live broadcast field from different angles by the field collection device.

In the process, the field terminal device also needs to perform operations such as encoding, compressing, encrypting and the like on the video stream.

In step S32, the terminal device transmits the acquired at least one video stream to the cloud device.

In implementation, step S32 may include: and transmitting at least one video stream to the cloud equipment by adopting a set account.

The action of transmitting the video stream to the cloud end is executed by the field terminal device, and the field terminal device is directly connected with the field acquisition device, so that the video stream acquired by the field acquisition device is transmitted to the cloud end device. For example, the field terminal device may be a computer, and the computer is connected to the camera and the microphone to transmit the video stream.

Further, the step of transmitting at least one video stream to the cloud device by using the set account means that: the field terminal device adopts the account to log in the cloud device, and transmits the video stream to the cloud device after logging in the cloud device; the specific implementation process may include: sending the set account and the corresponding password to the cloud equipment; and after the set account and the corresponding password are verified by the cloud equipment, transmitting at least one video stream to the cloud equipment. In this process, the cloud device needs to authenticate the account and the corresponding password sent by the terminal device, and further, since the cloud director and the cloud transcoding device may not have an authentication function, the cloud device may further include a server for authenticating the terminal device, and the server authenticates the terminal device before video stream transmission.

The set account here corresponds to an account used when the cloud device outputs the live stream to the user device, and is, for example, the same account. The cloud end equipment outputs an account used in live streaming to the user equipment, namely an anchor account. For example, the set account may be the same as the anchor account, or a corresponding table of the set account and the anchor account is stored in the cloud device, and when a live stream selected from multiple paths of video streams sent by the set account is output, the anchor account corresponding to the set account in the corresponding table is output.

In the embodiment of the disclosure, the terminal device may acquire the account and the password input by the user through the web page or the client, and then send the account and the password to the cloud device.

In step S33, the cloud device receives multiple video streams sent by at least one terminal device, where the multiple video streams are used to transmit video data collected from a live broadcast.

The multi-channel video stream is a multi-channel video stream acquired in the same live broadcast site or a multi-channel video stream acquired in different live broadcast sites.

Wherein, the multichannel video stream that at least one terminal equipment sent is received to cloud end equipment includes:

the cloud device receives multiple paths of video streams sent by at least one terminal device by using the same account (the set account).

In this process, the cloud device also needs to perform operations such as decryption, decompression, decoding, and the like on the video stream.

In step S34, the cloud device selects one video stream from the multiple video streams as a live stream.

In this embodiment of the disclosure, because the cloud end device can receive multiple paths of video streams simultaneously, the cloud end device needs to select one path to be forwarded and pushed as a live stream, and it is ensured that viewers can normally watch live streams.

The step S34 can be implemented in various ways:

in the first method, a video stream with a predetermined number is selected as a live stream according to the number of received multiple video streams. The predetermined number may be determined as follows: and acquiring a preset number list, and selecting the numbers in the preset number list as preset numbers according to the sequence. The sequential selection refers to selecting a number of a video stream after a current live stream number in a preset number list, and when the current live stream number is a first selection number, selecting a number of a first video stream in the preset number list. That is, step S34 may be to select a video stream for the first time and output it as a live stream, or may be to switch the live stream.

For example, the cloud device can receive 5 video streams numbered 1 to 5, the predetermined number list may be 1, 4, 3, 2, and 5, and at this time, the cloud device may select the video stream numbered 1 as a live stream.

The number of the video stream may be set by the terminal device, and the terminal device carries the number when transmitting the video stream. For multiple video streams transmitted in the same live broadcast site, the numbers of the video streams may correspond to the shooting angles of the video streams, for example, the shooting angles of the video streams are, in order from 1 to 5, right in front, left in front, right in front, back, and above the stage. The visual angle of the video stream with the number of 1 is the main visual angle, and the video stream with the number of 1 is used as the first of the list, so that the audience can watch the whole scene from the front of the stage at the beginning of live broadcasting, the stage and the live broadcasting content can be preliminarily recognized, and the later visual angle can be conveniently switched. For multiple video streams transmitted on different live broadcast sites, the number of the video stream may correspond to each live broadcast site, and when there are multiple live broadcast sites and there are multiple video streams on one site, a combination of the site number and the view angle number may also be used as the number of the video stream, for example, just in front of site 1, above site 2, and the like.

The number of the video stream can also be set by the cloud device, and at this time, when the picture synthesis scheme is set in advance, the picture of the video stream and the corresponding number can be displayed, so that the setting by a user is facilitated, which is described in detail later.

In the second mode, according to the code rates of the received multiple paths of video streams, the video stream with the highest code rate in the multiple paths of video streams is selected as the live stream. The code rate refers to the code rate of each video stream when the field acquisition device transmits the video stream to the cloud device, and the code rate of the video stream is the data bit transmitted in unit time during video transmission, so that the higher the code rate of video stream transmission is, the better the picture quality is, and the video stream with the highest transmission code rate can be selected by the live broadcast stream. This may ensure the viewing experience of the viewer.

Further, when the live stream is selected according to the code rate of the video stream, the live stream can be selected according to the real-time code rate, and the live stream can also be selected according to the average code rate in a period of time.

And in the third mode, one video stream is randomly selected from the multiple video streams as a live stream. This option increases the viewer's freshness and avoids starting the live broadcast with the same video stream each time.

In this step, the act of selecting a live stream is performed by the cloud director.

In step S35, the cloud device outputs the live stream.

And outputting the selected live stream to the user equipment, wherein the step of outputting the live stream comprises transcoding the live stream and outputting the live stream.

In this step, the transcoding action of the live stream is performed by the cloud transcoding device.

In implementation, step S35 may include the following implementation manners: in a first implementation, a direct broadcast stream is transcoded; and outputting the transcoded live stream to user equipment. In a second implementation manner, transcoding is performed on received multiple paths of video streams; and outputting the transcoded live stream to user equipment.

The first implementation may have the following two cases, the first case: after selecting the live stream, the cloud broadcasting guide station outputs the video stream to the cloud transcoding equipment; and the cloud transcoding equipment transcodes and outputs the live stream. In the second case: the cloud broadcasting guide table outputs all the multiple paths of video streams to the cloud transcoding equipment, and meanwhile, the serial number of the live stream is notified to the cloud transcoding equipment; and the cloud transcoding equipment transcodes the multiple paths of video streams simultaneously and outputs the transcoded live streams.

The transcoding of the video stream can be from a camera video format (such as AVI format) to a video format (such as h.263/h.264/Flash/etc.) played by a website or a mobile phone application.

Further, the cloud transcoding device may use a Fast forwarding Moving Picture Experts Group (ffmpeg) framework to perform audio and video transcoding and processing services on the video stream, and then output the video stream.

In step S36, when the cloud device detects a set trigger event, the cloud device selects a new video stream from the multiple video streams as a live stream.

In this step, when the cloud device detects a set trigger event, the cloud device determines a live stream (video stream) output when the set trigger event occurs, and then selects a live stream among other video streams (except the video stream output when the set trigger event occurs) in the received video stream.

The manner in which the cloud device selects a new live stream (step S36) and the manner in which the cloud device selects a live stream (step S34) may be the same or different.

For example, when the live stream is selected in the predetermined number, the new live stream may be selected in the manner of selecting a video stream whose number is one bit after the number of the live stream output when the set trigger event occurs. When the live stream is selected, the video stream with the highest code rate in the multiple paths of video streams is selected as the live stream, and when the new live stream is selected, the video stream with the highest code rate in other received video streams can be selected as the live stream. The live stream is selected in a manner that when one video stream is randomly selected as the live stream, a new live stream is selected in a manner that a video stream with the highest code rate is selected as the live stream from other video streams in the received video streams. When the live stream is selected, the video stream with the highest code rate in the multiple video streams is selected as the live stream, and when the new live stream is selected, one video stream can be randomly selected from other video streams in the received video streams as the live stream. It should be noted that the new live stream is referred to as the previous live stream.

Still further, the method may further comprise: recording the time of each video stream as a live video stream, which may include the start time and the end time of the video stream as the live stream; when the time length from the time when the video stream as the live stream ends to the current time exceeds the preset time length, the video stream can be re-used as a candidate of the live stream, and can be re-used as the live stream through the selection of the live stream selection scheme.

The set triggering event herein may include at least one of a set event and an emergency event. The set event may include that the time reaches a set time point, or the output time of the currently output live stream reaches a predetermined time length. For example, the set time point may be each hour, and step S36 may include switching the live stream at each hour; the predetermined time period may be one hour, and step S36 may include switching the live stream when the output of the current live stream reaches one hour. The emergency event may include that a code rate of a currently output live stream is less than or equal to a threshold value. For example, the threshold may be 0, and when the bitrate of the current live stream is 0, the live stream is switched.

In the embodiments of the present disclosure, when a different set trigger event is detected, a new live stream may be selected in a different manner. For example, when the trigger event is that the time reaches a set time point, or the output time of the currently output live stream reaches a predetermined time, the mode of selecting a new live stream may be to select a video stream with a number one bit after the number of the live stream output when the set trigger event occurs to output; when the triggering event is that the code rate of the currently output live stream is less than or equal to the threshold, the mode when the new live stream is selected may be to select a video stream with the highest code rate as the live stream from other video streams in the received video stream.

In the embodiment of the present disclosure, the video stream selection scheme and the set trigger event may be set in advance. The process can adopt the following modes:

acquiring live broadcast setting information, wherein the live broadcast setting information is used for setting at least one of a video stream selection scheme and a set trigger event, and the video stream selection scheme is provided for the cloud end equipment so that the cloud end equipment can determine live broadcast streams according to the video stream selection scheme; and setting at least one of a video stream selection scheme and a set trigger event according to the live broadcast setting information.

Here, the acquiring of the live setting information may be performed in the following manner: the cloud device provides a program director interface and acquires live broadcast setting information input by a user through the program director interface. The director interface may be an interface of a director web page or an interface of a director software.

Fig. 2D is a schematic diagram of a director's interface provided by the present disclosure, referring to fig. 2D, that may provide a video stream selection scheme interface 1A, the video stream selection scheme interface 1A including a selection button 1A and a corresponding parameter selection box 1 b. For example, the video stream selection scheme may include three buttons, which correspond to the three schemes, respectively, and a user clicking different buttons 1a displays corresponding parameter selection boxes 1b for user input. When selecting a live stream according to the numbers, the user can set a predetermined number list in the parameter selection box. In randomly selecting a live stream, the user may set a range of random video streams within the parameter selection box, such as randomly within the video streams numbered 1-4, and so on.

For convenience of setting, the multiple video streams may also be played on the director interface at the same time, that is, the multiple video streams are output at the same time through the director interface, so that when a user inputs a number of a video stream, the user can compare pictures of the video streams, see fig. 2D, the director interface includes a video output interface 3A, the interface 3A includes a display frame (and a corresponding number) of the multiple video streams, and the corresponding video streams can be viewed through the interface 3A, which is convenient for the user to select. In addition, the setting is that the number setting can be not only inputting the corresponding number, but also clicking the playing picture of the corresponding video stream, thereby facilitating the selection.

Wherein the playing of the multiple video streams simultaneously on the director interface may be associated with the second implementation of step S35: transcoding the received multiple paths of video streams; and outputting the transcoded multi-channel video stream through the director interface. Since the transcoding of the multiple video streams in this process can be performed together with step S35, and in this process, only the user needs to have a rough impression on the content of each video stream, and in consideration of resource consumption during transmission, the definition of the other video streams (the video streams except the live stream in the multiple video streams) can be reduced during transcoding (that is, the definition of the live stream is greater than that of the other video streams), thereby reducing transmission resource consumption.

The program director interface may provide an interface 2A for a set trigger event, where the interface 2A includes a selection button 2A and a parameter selection box 2b corresponding to the set trigger event, and the selection button 2A and the parameter selection box 2b may be designed with reference to the selection button 1a and the parameter selection box 1 b. For example, the button for selecting the set triggering event may include three buttons, which respectively correspond to the aforementioned three set triggering events. When switching the video streams according to the set time point, a user can set the corresponding time point; when the video stream is switched after the video stream output time reaches the preset time length, the user can set the length of the preset time length; when the code rate of the currently output live stream is smaller than or equal to the threshold value, and the video stream is switched, the user can set the threshold value of the code rate.

Further, when the program director interface is a web page, the web page can be set after the login web page, that is, the user enters the set web page after the login is successful, so that the safety performance is ensured, and the user can set the program anytime and anywhere.

In addition, in the embodiment of the disclosure, the cloud device may also monitor the multiple paths of video streams in real time, and output alarm information when the video streams have faults.

For example, the cloud device may detect a code rate of each path of video stream, and when the code rate is lower than a set value, consider that the path of video stream is faulty, and send an alarm message to a corresponding user, for example, send an email, a short message, and the like to the user for alarm.
