In addition, it should be noted that, fig. 1 is only one application environment provided by the present disclosure, and in practical application, other application environments may also be included, which is not described in detail in the embodiments of the present disclosure.
Specifically, the embodiment of the invention provides a live video switching method, which can improve the viewing experience of a user when live video is unsmooth. Fig. 2 is a schematic step diagram of a live video switching method provided in embodiments herein, where the method steps are as described in the examples or flowcharts, but may include more or fewer steps based on conventional or non-inventive labor. The order of steps recited in the embodiments is merely one way of performing the order of steps and does not represent a unique order of execution. When a system or apparatus product in practice is executed, it may be executed sequentially or in parallel according to the method shown in the embodiments or the drawings. As shown in fig. 2, the method may include:
S101: acquiring live stream data of a first direct-broadcasting source in real time, wherein the live stream data comprise video stream data and/or audio stream data;
s102: judging whether the first live broadcast source is in a live broadcast fluency state according to live broadcast stream data of the first live broadcast source;
s103: when the live broadcasting of the first direct broadcasting source is not smooth, the live broadcasting stream data pulling address of the user side is updated according to the address of the pulling server corresponding to the second direct broadcasting source, so that the user side views live broadcasting contents through the second direct broadcasting source.
It may be understood that in the embodiment of the present disclosure, the first direct broadcast source and the second direct broadcast source are used as direct broadcast sources of parallel direct broadcast, and are used for direct broadcast of the same main broadcast, and when the first direct broadcast source is used for direct broadcast, the second direct broadcast source is in a live broadcast active state, which is equivalent to that when the first direct broadcast source is used for direct broadcast (i.e. used as main direct broadcast), the second direct broadcast source is in a live broadcast backup state (i.e. live broadcast active state), and the state of collecting data of the direct broadcast stream is actually processed, except that no user side views the data. Through analyzing the live broadcast stream data of the first direct broadcast source, whether the first direct broadcast source is in a live broadcast fluency state can be judged, when the first direct broadcast source is not in the live broadcast fluency state, for example, live broadcast blocking occurs, when live broadcast pictures are not fluent to play, the second direct broadcast source can be directly turned over, a user watches live broadcast contents by acquiring the live broadcast stream data of the second direct broadcast source, stable data of the live broadcast data can be guaranteed through a double-live-broadcast source mode, and fluency and stability of live broadcast are guaranteed.
The live broadcast activation state comprises the steps of collecting main broadcast video and audio in real time, collecting courseware-free content in a live broadcast operation area, and pushing live broadcast stream data of a second live broadcast source obtained through collection to a push stream server corresponding to the second live broadcast source. That is, at the anchor end, the second live broadcast source collects video and audio information of the anchor in real time and pushes the video and audio information to the push server and the pull server of the background, and the pull server corresponding to the second live broadcast source can set corresponding data stream pull permission, so that when the first live broadcast source is normally live broadcast, the live broadcast content of the second live broadcast source cannot be received by a user end, and the single live broadcast source can be used for live broadcasting the teaching content of the anchor (i.e. a teaching teacher), so that the concentration and cohesiveness of users are improved, and the interaction experience between the anchor (i.e. the teaching teacher) and the users (i.e. the learner) is prevented from being influenced by the users scattered at different live broadcast sources.
When the second live broadcast source is in a live broadcast activation state, no courseware content exists in an operation area in the second live broadcast source, and no main broadcast operation exists in the operation area, namely, no actual main broadcast is performed in the second live broadcast source, and no main broadcast exists in the operation area, so that the second live broadcast source can be ensured to enter a live broadcast state at any moment, and meanwhile, the network resource rate of the second live broadcast source can be reduced before the real switching, thereby reducing the network load and improving the stability and reliability of the first live broadcast source in the live broadcast process.
It should be noted that, the first direct broadcast source and the second direct broadcast source are two independent direct broadcast channels, that is, two direct broadcast sources are configured with two different push channels and pull channels, so that when the first direct broadcast source is not smooth in direct broadcast, data transmission of the second direct broadcast source cannot be affected, and when the main broadcast is switched to the second direct broadcast source, the second direct broadcast source is guaranteed to have a stable data transmission channel, and smoothness and reliability of direct broadcast are guaranteed.
In one embodiment of the present disclosure, the first direct broadcast source and the second direct broadcast source may be two different sets of direct broadcast platforms, so as to implement dual-platform backup.
In this embodiment of the present disclosure, when the first direct broadcast source is not smooth, a direct broadcast switching signal is sent to the anchor, so that the anchor performs direct broadcast lecture through an operation area of the second direct broadcast source.
It can be understood that the two sets of live broadcast sources serving as the parallel live broadcast are equivalent to two sets of live broadcast equipment, so that when the first live broadcast source is live broadcast, the attention of a host and the operation area of courseware are on the first live broadcast source, and when the first live broadcast source is not smooth in live broadcast, the live broadcast needs to be switched to the second live broadcast source, and then the attention of the host needs to be switched to the live broadcast equipment of the second live broadcast source, thereby avoiding the situation that the host broadcast picture and the lecture content are not matched, and improving the quality of network teaching.
In some embodiments of the present disclosure, when the first direct broadcast source is not smooth, sending a direct broadcast switching signal to the anchor, so that the anchor performs direct broadcast teaching through an operation area of the second direct broadcast source, including:
when the first direct broadcasting source is not smooth in live broadcasting, a direct broadcasting source adjusting signal is sent to the anchor, so that the anchor adjusts the live broadcasting visual angle, and the adjusted visual angle is consistent with the operation visual angle of the second direct broadcasting source.
Therefore, the anchor can make the matching degree of the anchor and the second live broadcast source higher by adjusting the visual angle, so that the anchor can broadcast live broadcast through the second live broadcast source higher, smaller changes of the anchor and a live broadcast interface (namely an operation area) before and after switching are ensured, thereby realizing noninductive switching on a learner at a user side and ensuring continuity of a live broadcast teaching process.
Of course, in the live broadcast source switching process, the switching of the main broadcast video acquisition (such as a camera) and the audio acquisition device (such as a microphone) is also involved, in order to ensure the continuity and consistency before and after the switching, the first live broadcast source and the audio acquisition device in the second live broadcast source can be configured with the same parameters, and the installation angle and the installation position (with the corresponding live broadcast device) can be consistent, so that after the main visual angle is switched, the video acquisition device and the audio acquisition device of the second live broadcast source can acquire the data with the same range and tone quality as the corresponding acquisition device of the first live broadcast source, thereby ensuring the continuity and stability of video and audio.
In some other embodiments, the first direct broadcast source and the second direct broadcast source may use the same set of video capturing device and audio capturing device, so that consistency of video quality and audio quality before and after switching can be ensured, but on the basis of adjustment of a main broadcast viewing angle, angles of the corresponding video capturing device and audio capturing device also need to be adjusted accordingly, so that the main broadcast is in a proper video range, and the captured audio is in a better quality range, and other configurations of the video capturing device and the audio capturing device in the first direct broadcast source and the second direct broadcast source are also possible, which are not limited in the embodiments of the present specification.
In this embodiment of the present disclosure, as shown in fig. 3, when the first direct broadcast source has a live broadcast unsmooth, sending a live broadcast switching signal to the anchor, so that the anchor performs live broadcast teaching through an operation area of the second direct broadcast source further includes:
s201: when the first direct broadcasting source is not smooth in live broadcasting, acquiring current page information of courseware in an operation area of the first direct broadcasting source;
s202: copying courseware in the operation area of the first direct broadcast source to the operation area of the second direct broadcast source;
S203: and updating courseware in the operation area of the second live broadcast source to a corresponding page according to the current page information of the courseware in the operation area of the first live broadcast source, so that a host broadcast carries out live broadcast teaching through the courseware in the operation area of the second live broadcast source.
It can be understood that besides the adjustment of the attention of the host, the operating area of the second live broadcast source needs to be consistent with the state (i.e. the page of the courseware, such as the page of the PPT) of the operating area of the first live broadcast source before switching, so that a learner at the user side does not have a mutation picture when pulling the data in the second live broadcast source, and the continuity and quality of network teaching are ensured. Therefore, the progress of the host lesson can be obtained by acquiring the current page information of the courseware in the operation area of the first live broadcast source before switching, then the same courseware is copied in the operation area of the second live broadcast source, and then the page of the courseware is adjusted to the part of the host lesson, so that the automatic synchronization of the page information of the courseware is realized, the efficiency of switching the live broadcast sources is improved, the smoothness and the stability of live broadcast are greatly improved, and higher user learning experience is ensured.
In some other embodiments, the process of synchronizing courseware in the operation area of the second live broadcast source may also be implemented by manually turning pages by the host or by assisting in turning pages by a course assistant, so that interaction between the first live broadcast source and the second live broadcast source data may be reduced, thereby ensuring independence of the first live broadcast source and the second live broadcast source, and further enabling higher live broadcast stability of the first live broadcast source and the second live broadcast source.
In this embodiment of the present disclosure, as shown in fig. 4, the determining, according to the live stream data of the first live source, whether the first live source is in a live smooth state includes:
s301: calculating the live broadcast quality of the first direct broadcast source according to the acquisition frame rate and the code rate of the video and/or the audio of the first direct broadcast source in a preset time period;
s302: and judging whether the first live broadcast source is in a live broadcast fluency state according to the live broadcast quality.
The judging of the direct current fluency of the first direct current source can utilize the acquisition frame rate and the code rate of the video and/or the audio of the first direct current source. The live broadcast quality may be the quality of a live broadcast picture within a preset time period, where the preset time period may be set according to practical situations, for example, 5s, 10s, 30s, etc., and specific numerical values are not limited in the embodiments of the specification.
The frame rate is the number of frames of the collected pictures of the camera in unit time or the number of audio frames (or media frames) of the microphone in unit time, and the larger the frame rate is, the smoother the picture is and the better the quality of the picture is; the smaller the frame rate, the more dynamic the picture is jumped, the worse the picture quality, and in live broadcast scene, the camera acquisition frame rate can be 15 frames, and the audio acquisition frame is usually about 100 frames.
The code rate is the number of pictures or audios which are displayed in unit time and compressed, the higher the code rate is, the higher the definition of pictures and audios is, the higher the quality of video is, the lower the definition of pictures and audios is, the lower the quality of video is, the worse the quality of video is, for example, in a live broadcast scene, the code rate of video can be 900kbps, a test audio link before a live broadcast is performed, the code rate can be reduced to about 200kpbs when the pictures are still, and if the code rate is seriously reduced in the live broadcast process, for example, if about 200kpbs is reduced, the pictures can be stuck and dithered, and the watching quality is affected.
In this embodiment of the present disclosure, the calculating, according to an acquisition frame rate and a code rate of video and/or audio of the first direct broadcast source in a preset time period, a direct broadcast quality of the first direct broadcast source includes:
counting the total times that the acquisition frame rate and the code rate of the video and/or the audio of the first direct-broadcasting source in the preset time period are lower than the respective threshold value according to the acquisition frame rate and the code rate of the video and/or the audio of the first direct-broadcasting source in the preset time period;
when the total times are lower than preset times, determining that the first direct-seeding source is in a direct-seeding fluency state in the preset time period;
And when the total times are not lower than the preset times, determining that the first direct broadcast source is in a direct broadcast unsmooth state in the preset time period.
It may be understood that, in the embodiment of the present disclosure, whether the first direct broadcast source is in a fluent state in a preset time period is determined according to the change condition of the acquisition frame rate and the code rate of the video and/or the audio in the preset time period, where the sum of the number of times that the acquisition frame rate of the video and/or the audio is lower than the corresponding threshold value and the number of times that the code rate of the video and/or the audio is lower than the corresponding threshold value is taken as the total number of times, and the total number of times is compared with the preset number of times, when the total number of times exceeds the preset number of times, it is indicated that the number of times that the change of the live broadcast stream data of the first direct broadcast source in the preset time period is larger, so that the live broadcast stream is not smooth, and therefore the live broadcast quality in the preset time period is poor.
For example, the preset time period is 10s, taking the acquisition frame rate and the code rate of the video as examples, and the acquisition frame rate (unit: frame) obtained in the preset time period is: 12. 15, 13, 18, 20, 7, 10, 15, 13, 14; the acquired code rate (unit: kbps) is: 880. 860, 930, 430, 180, 230, 750, 150, 400, 1020; the threshold value set by the acquisition frame rate is 14, the threshold value set by the code rate is 300, the number of times that the actual acquisition frame rate is lower than the threshold value in a preset time period is 5, the number of times that the actual code rate is lower than the threshold value is 3, the total number of times is 8, the preset number of times is 7, the total number of times exceeds the preset number of times, and the first direct broadcasting source can be determined to be in a direct broadcasting unsmooth state in the preset time period.
The method comprises the steps of comparing specific collected data with corresponding threshold values to determine the times that the collected frame rate or code rate does not meet the requirements in a preset time period, so as to determine the live broadcast quality of a first direct broadcast source, and the fluency of live broadcast can be determined through the true value of the data.
In some other embodiments, the fluency of the live broadcast may also be determined by the degree of change of the data, and optionally, the calculating, according to the acquired frame rate and the code rate of the video and/or the audio of the first direct broadcast source in the preset time period, the live broadcast quality of the first direct broadcast source further includes:
according to the video and/or audio acquisition frame rate and the code rate of the first direct broadcast source in a preset time period, calculating and obtaining a stability coefficient of the acquisition frame rate and a stability coefficient of the code rate in the preset time period;
judging whether the stability coefficient of the acquisition frame rate is lower than a first threshold value and whether the stability coefficient of the code rate is lower than a second threshold value;
if the stability coefficient of the acquisition frame rate is lower than a first threshold value and the stability coefficient of the code rate is lower than a second threshold value, determining that the first direct broadcast source is in a direct broadcast fluent state in a preset time period;
if the stability coefficient of the acquisition frame rate is not lower than a first threshold value or the stability coefficient of the code rate is not lower than a second threshold value, determining that the first direct broadcast source is in a direct broadcast non-fluent state in a preset time period.
It may be understood that the stability factor may be a variation degree of an acquisition frame rate and a code rate of the video and/or audio in the preset time period by the first direct broadcast source, and the greater the stability factor, the greater the variation degree is indicated, which represents that the acquisition frame rate or the code rate of the video and/or audio is unstable in the preset time period, the greater variation degree is presented, and further, the living broadcast quality is indicated, and as an alternative, the stability factor may be a variance or a standard deviation of the acquisition frame rate and the code rate, which is not limited in the embodiment of the present specification.
The frame rate and the code rate are simultaneously judged, when one of the frame rate and the code rate are not met, the first direct-broadcasting source can be determined to be in a direct-broadcasting fluent state in a preset time period, and only when the frame rate and the code rate are met (namely, the stability coefficient of the frame rate is lower than a first threshold value and the stability coefficient of the code rate is lower than a second threshold value), the first direct-broadcasting source can be determined to be in the direct-broadcasting fluent state in the preset time period, wherein the first threshold value and the second threshold value are set according to actual conditions, and the method is not limited in the embodiment of the specification.
The step is to determine whether the data is stable in a preset time period or not through the variation degree of the real-time data, and when the stability coefficient is larger, the fluctuation of the acquired data (the acquired frame rate or the code rate) in the preset time period is larger, so that an unstable live broadcast picture can be watched at the user side, and poor live broadcast quality is caused, and therefore the live broadcast quality is obtained through the relativity of the live broadcast stream data, the accuracy of live broadcast fluency judgment can be improved, and the watching experience of the user side is ensured.
When the live broadcast source is required to be switched, as shown in fig. 5, optionally, when the first live broadcast source is not smooth in live broadcast, the live broadcast stream data pulling address of the user side is updated according to the address of the pulling server corresponding to the second live broadcast source, so that the user side views live broadcast content through the second live broadcast source, including:

s402: and adjusting the content distribution protocol according to the address information of the streaming server corresponding to the second live broadcast source and the content distribution protocol of the first live broadcast source so as to update the pulling address of the live broadcast stream data of the user side.
It may be understood that, in the embodiment of the present disclosure, by adjusting the content distribution protocol of the first live broadcast source, the adjusted content distribution protocol is matched with the second live broadcast source, so that the user side that can be the user side pulls live broadcast stream data in the pull stream server corresponding to the second live broadcast source, thereby implementing the noninductive switching of the pull stream channel at the user side, and guaranteeing the smoothness and stability of live broadcast.
In this embodiment of the present disclosure, according to address information of a streaming server corresponding to the second live broadcast source and a content distribution protocol of the first live broadcast source, adjusting the content distribution protocol to update a pull address of live broadcast stream data of the user side includes:
acquiring a pulling website position and a pulling website parameter in a content distribution protocol of the first live broadcast source;
and replacing the pulling website parameters according to the address information of the pulling server corresponding to the second live broadcast source and the pulling website position to obtain a content distribution protocol of the second live broadcast source, so that the user side obtains live broadcast stream data of the second live broadcast source according to the content distribution protocol of the second live broadcast source.
The change of the pulling channel of the user side can be realized rapidly by replacing the pulling website in the content distribution protocol, and the change of other configuration environments can be included in the actual change, and alternatively, the change can be automatically executed through a preset script, and when the switching of the live broadcast source is required, the corresponding script is directly triggered, so that the automatic change of the content distribution protocol and other configuration environments is realized, and the efficiency of the switching of the live broadcast source is improved.
In an embodiment of the present specification, the method further includes:
after the live broadcasting of the main broadcasting is completed, acquiring live stream data of the first live broadcasting source and the second live broadcasting source;

According to the video live broadcast switching method provided by the embodiment of the specification, when live broadcast of the first direct broadcast source is not smooth, live broadcast can be taken over through the second direct broadcast source by setting up the double direct broadcast sources, so that the live broadcast smoothness and stability caused by the fault of the first direct broadcast source are avoided, a live broadcast reconstruction room is not needed by a platform for constructing parallel live broadcast in advance, a user does not need to reenter the live broadcast room, and the user experience is improved.
