Detailed Description
The embodiment of the application provides a video carousel method and related equipment, which can solve the problems of resource waste, high cost, lack of interactivity between users and a main broadcast and between users.
The terms "first," "second," "third," "fourth," and the like in the description and in the claims of the present application and in the drawings described above, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that the embodiments described herein may be practiced otherwise than as specifically illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus. The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments.
Fig. 1 is a schematic diagram of a conventional video carousel architecture in the prior art, and as shown in fig. 1, the video carousel system needs a stream pushing transcoding server to read videos from a main broadcasting end or a video file server in sequence and push the videos to a distribution network CDN, and specifically, the transcoding server obtains video files in sequence according to a preset carousel list, converts the video files into live stream information and pushes the live stream information to a live broadcasting room. The user acquires the picture through a common live streaming mode. The push stream involves bandwidth costs and transcoding server costs. The above cost expenditure is higher when there are more anchor for the carousel. Moreover, because the stream information does not contain video information, the client cannot analyze the current playing video number and the playing time axis progress, and the playing progress of the carousel video of each client and the anchor terminal cannot be kept consistent, so that the interactivity between the carousel video, the user and the anchor and the user and the interactivity between the user and the user are reduced. The live broadcast/carousel/barrage server may issue the barrage to the CDN.
Based on the problem of the video carousel system in fig. 1, referring to fig. 2, a video carousel method provided in this embodiment of the present application is used for a live server (that is, an execution subject of the video carousel method in this embodiment is a live server); the method of fig. 2 is implemented based on the architecture of the video carousel system of fig. 6 (fig. 6 is a diagram of a new video carousel architecture provided by the present invention), and the architecture of fig. 6 is an improvement of the conventional video carousel architecture of fig. 1 to overcome the above-mentioned defects of fig. 1
Specifically, the video carousel method includes the following steps:
s110, when the live broadcasting room of the anchor terminal is switched from the live broadcasting state to the carousel state, receiving a carousel request sent by a client side positioned in the live broadcasting room.
In some examples, when the anchor of the live broadcast room is not live, in order to keep the user continuously paying attention to the live broadcast room, the live broadcast room is switched from the live broadcast state to the carousel state for video carousel, and if a user wishes to watch carousel video, the live broadcast server receives a carousel request sent by a client located in the live broadcast room. For example, the carousel request may include a room number of the live room.
S120, based on the carousel request, acquiring carousel information according to the current carousel condition of the live broadcast room, wherein the carousel information comprises: carousel video identification and time axis data;
illustratively, when the live broadcast server receives the carousel request, the live broadcast room selected by the user to enter is determined according to the room number information included in the carousel request. And the live broadcast server acquires carousel information comprising carousel video identification and time axis data according to the current carousel condition of the live broadcast room. The video identification can determine the video that the live server is currently carousel, and the timeline data can determine the point in time of the video that the live server is currently carousel.
Illustratively, when the live broadcast server receives the carousel request, the live broadcast room selected by the user to enter is determined according to the room number information included in the carousel request. And the live broadcast server acquires the carousel information comprising the carousel video identifier and the time axis data according to the current carousel condition of the live broadcast room. The video identification can determine the video that the live server is currently carousel, and the timeline data can determine the point in time of the video that the live server is currently carousel.
In addition, in some cases, since the live broadcast can be seen from the push stream starting to the server processing to the delivery to the user, there are different degrees of delay, generally ranging from 5 seconds to 30 seconds. And historical bullet screen pushing is carried out according to the time axis of the video progress of the server, and the time delay from the sending of the broadcast from the server to the receiving of the user is generally less than 1 second. It can be understood that the video is delayed, and the bullet screen is not delayed. The user can receive the bullet screen at different moments from 5 seconds to 30 seconds in advance. The time of the historical bullet screen display and the current playing picture is seriously staggered. For example, the live server 19:00 starts playing video, the 2 nd minute of the video has a history barrage, the server pushes the barrage at 19 o 'clock 02 min, the picture seen by the user is the picture pushed by the server 19 o' clock 01 min 30 sec, and the transmission delay is 30 sec, namely the picture of the 1 st: 30 sec of the video. But the bullet screen displayed is video minute 2.
Therefore, the client cannot analyze the currently played video number and the playing timeline progress under the condition that the streaming information has no video information. Therefore, there is a delay in the case where the server pushes the history bullet screen earlier than the client receives the screen. Meanwhile, the bullet screen sent by the user cannot accurately guide the user real-time bullet screen into the corresponding time axis in the historical video bullet screen because the server does not know the current picture delay condition of the client.
In some examples, in order to solve the above problem, custom timeline information can be inserted into the information pushed in the screen to inform the client that the barrage is temporarily saved to a specified timeline and then displayed, so that the problem can be solved. However, since the distribution of the live stream generally selects a plurality of operator services at the same time, each operator is required to support transcoding of the custom information, and the implementation difficulty, error rate and cost are increased.
In view of the above problem, the video carousel method provided in the embodiment of the present application further includes:
the client side comprises: the customer end is based on the carousel information to live server sends the barrage message, the barrage message include the barrage content and with the barrage content corresponds carousel video sign with the time axis data, so that live server according to with the barrage content corresponds carousel video sign with the time axis data is leading-in the barrage message, in order to keep the barrage content that the current carousel video's of broadcast in the live room picture corresponds with the customer end is directed against the barrage content that the picture sent is synchronous.
Accordingly, the live server side does not include: live broadcast server receiving client side is based on the carousel information to live broadcast server sends the barrage message, live broadcast server can be according to with barrage content corresponds carousel video sign with the time axis data is leading-in barrage message, in order to keep the barrage content that the current carousel video's of live broadcast room broadcast picture corresponds with the client side is directed against the barrage content that the picture sent is synchronous.
The client requests the live broadcast server for the video information currently played by the anchor terminal, so that the client definitely knows the currently played video number and the playing progress time axis of the anchor terminal. The historical bullet screen display can be accurately matched with the time axis. Meanwhile, when the client sends the real-time bullet screen, the client can carry the current video number and the time shaft information. The server side can accurately import the historical bullet screen for storage.
And S130, issuing the carousel information to the client, so that the client requests a target carousel video from a Content Delivery Network (CDN) according to the carousel video identifier, and plays the target carousel video according to the time axis data, so as to keep the frames of the target carousel video played by the client and the current carousel video played in the live broadcast room synchronous.
Exemplarily, the content delivery network CDN includes a video file server and a network node;
the step of sending the carousel information to the client, so that the client requests a target carousel video from a Content Delivery Network (CDN) according to the carousel video identifier, and plays the target carousel video according to the time axis data, so as to keep the frames of the target carousel video played by the client and the current carousel video played by the live broadcast room synchronized, includes:
and the live broadcast server sends the carousel information to the client so that the client initiates a stream pulling request of a target carousel video to the video file server according to the carousel video identifier, and the network node sends a corresponding target carousel video stream to the client so that the client plays the target carousel video according to the time axis data to keep the frames of the target carousel video played by the client and the current carousel video played in the live broadcast room synchronous.
Specifically, the live broadcast server starts carousel, records and maintains a uniform play progress according to time lapse, for example, the nth video in the current list and the xth minute of the video time axis, and the client enters the live broadcast room and requests the server interface getvideolist (int roomid) to the live broadcast server to obtain the carousel state and video source information. And then autonomously pull the specified video from the interface getvideofile (int videoid) of the video file server and jump to the specified timeline for playing. Keeping most clients watching at the same schedule. Therefore, the unified viewing progress of all the clients can be maintained as in live broadcasting, and the situation that the user A looks at the head, the user B looks at the tail, and the mutually-issued barrage content is unrelated and cannot interact with each other is avoided. If the user A looks at the first video and the user B looks at the second video, different users in the same live broadcast room cannot interact with each other, and to ensure that the users enter the live broadcast room to see the video contents on the same time line, the user inquires of the live broadcast server to request the second number of the video being watched, automatically pulls the second number of the video, and plays the video from the second, so that the users can see the same time line.
And the client side directly requests the video file, and the video file belongs to static resources and can be stored in the conventional CDN. The cost is much lower than the network cost and the server cost of live stream push. Meanwhile, under the condition of no user viewing, any computing resource and network resource are not consumed.
The foregoing example is described based on a live broadcast server, fig. 3 is a schematic flowchart of another possible video carousel method provided in an embodiment of the present application, and the following description is given, in combination with fig. 3, on the basis of a client, where the video carousel method is used for the client (that is, an execution subject of the video carousel method in the embodiment of fig. 3 is the client), and includes: S210-S230.
S210, when the live broadcasting room of the anchor end is switched to the carousel state from the live broadcasting state, a carousel request aiming at the live broadcasting room is sent to a live broadcasting server.
In some examples, when the anchor of the live broadcast room is not live, in order to keep the user continuously paying attention to the live broadcast room, the live broadcast room is switched from the live broadcast state to the carousel state for video carousel, and if a user wishes to watch carousel video, the live broadcast server receives a carousel request sent by a client located in the live broadcast room. For example, the carousel request may include a room number of the live room.
S220, receiving carousel information sent by the carousel request and fed back by the live broadcast server, where the carousel information is obtained by the live broadcast server according to a current carousel condition of the live broadcast room, and the carousel information includes: carousel video identification and timeline data.
Illustratively, when the live broadcast server receives the carousel request, the live broadcast room selected by the user to enter is determined according to the room number information included in the carousel request. And the live broadcast server acquires the carousel information comprising the carousel video identifier and the time axis data according to the current carousel condition of the live broadcast room. The video identification can determine the video that the live server is currently carousel, and the timeline data can determine the point in time of the video that the live server is currently carousel.
According to some embodiments, also in the case that the client has no video information in the streaming information, the currently played video number and the playing timeline progress cannot be parsed. Therefore, there is a delay in the case where the server pushes the history bullet screen earlier than the client receives the screen. Meanwhile, the bullet screen sent by the user cannot accurately guide the user real-time bullet screen into the corresponding time axis in the historical video bullet screen because the server does not know the current picture delay condition of the client.
In some examples, in order to solve the above problem, custom timeline information can be inserted into the information pushed by the screen to inform the client that the problem can be solved by temporarily saving the bullet screen to the specified timeline and then displaying the bullet screen. However, since the distribution of the live stream generally selects a plurality of operator services at the same time, each operator is required to support the transcoding of the customized information, and the implementation difficulty, error rate and cost are increased.
In view of the foregoing problems, a video carousel method for a client provided in an embodiment of the present application may include:
based on the carousel information to live broadcast server sends the barrage message, the barrage message include barrage content and with the barrage content corresponds carousel video sign with the time axis data, so that live broadcast server according with the barrage content corresponds carousel video sign with the time axis data is leading-in the barrage message, in order to keep the barrage content that the current carousel video's of broadcast in the live broadcast room picture corresponds with the customer end is directed against the barrage content that the picture sent is synchronous.
The client requests the live broadcast server for the video information currently played by the anchor terminal, so that the client definitely knows the currently played video number and the playing progress time axis of the anchor terminal. The historical bullet screen display can be accurately matched with the time axis. Meanwhile, when the client sends the real-time bullet screen, the client can carry the current video number and the time shaft information. The server side can accurately import the historical bullet screen for storage.
In some cases, the client may not have the playback progress consistent with other users due to pause, etc. In order to solve the above problem, before the step of requesting a target carousel video from a content delivery network CDN according to the carousel video identifier and playing the target carousel video according to the time axis data to keep the pictures of the target carousel video played by the client and the current carousel video played in the live broadcast room synchronized, the method may include:
receiving the carousel calibration information sent by the live server at preset time intervals, wherein the carousel calibration information is obtained by maintaining the carousel information by the live server according to time lapse, and the carousel calibration information includes: carousel video calibration identification and time axis calibration data;
and requesting a target carousel video from a Content Delivery Network (CDN) according to the carousel video calibration identifier, and playing the target carousel video according to the time axis calibration data so as to keep the pictures of the target carousel video played by the client and the current carousel video played by the live broadcast room synchronous.
In some examples, the step of requesting a target carousel video from a content delivery network CDN according to the carousel video calibration identifier, and playing the target carousel video according to the time axis calibration data to keep the pictures of the target carousel video played by the client and the current carousel video played in the live broadcast room synchronized may include:
if the currently played video of the client needs to be switched according to the carousel video calibration identifier, directly switching to the target carousel video for playing according to the carousel video calibration identifier and the time axis calibration data when the currently played video of the client is not finished so as to keep the pictures of the target carousel video played by the client and the currently played carousel video played by the live broadcast room synchronous; and/or the presence of a gas in the gas,
if the currently played video of the client needs to be switched according to the carousel video adjustment identifier, buffering the target carousel video in advance according to the carousel video calibration identifier and the time axis calibration data, and switching to the buffered target carousel video to play after the currently played video of the client is finished.
Specifically, the live broadcast server periodically pushes the currently played video information, the progress and the video information to be played in the future to the client through the barrage channel interface sendMessage (Byte [ ] data). The client checks whether the current playing progress is consistent, and if the progress difference is large, the client needs to synchronize to the playing progress consistent with the live broadcast server. In order to avoid frequent jumping of the client, when the live broadcast server switches to the next video, the client abandons the current video playing to be switched to the next video which is played by the same live broadcast server. As shown in fig. 4, when the live broadcast server issues play start video 3(cur ═ 3), if the client does not finish playing video 2, the client actively abandons playing of the remaining video 2, and starts playing video 3.
For example, since the carousel is a sequential playing of a plurality of videos, the client may request the next video again from video to video, and there may be a request delay and a buffering time of a new video. Therefore, the playlist calibration information delivered by the live server each time includes the current video (cur), the next video (next), and the next2 videos (next2), as shown in fig. 5, when the client end finishes playing the current video 1, the background buffers the next video 2 in a silent manner about 15 seconds before the current video 1 finishes playing. When the video 1 is played, the video 2 with a segment of the buffered video can be played seamlessly. The experience that the user of switching the video is not aware is achieved.
Specifically, the aforementioned getvideolist (int roomid): interface function: the client requests the carousel server to acquire the video information which is being played in the current carousel list in the live broadcast room with the specified roomID room number and the information of the next2 videos which need to be played. Interface parameters: int roomi ID, live room ID. Interface return value: a currently played video id (int video id), a currently played progress timeline (int, timestamp), and current video multimedia information (conventional video multimedia information such as coding format, code rate, width and height, audio information, etc.); the ID of the video to be played next and the multimedia information of the video; next the second video ID, video multimedia information to be played.
The aforementioned getvideofile (int videoid): and (3) interface functions: the client requests the video server to acquire a video file of the specified video ID. Interface parameters: int video ID, video ID. Interface return value: and returning the playing address of the video corresponding to the video ID in the video file server and the multimedia information (such as the conventional video multimedia information of coding format, code rate, width, height, audio and the like) of the video.
The aforementioned sendMessage (Byte [ ] data): interface function: and in the live broadcast barrage channel, the server packs the instruction/information data into a message and sends the message to the client. Interface parameters: byte [ ] data message. Interface return value: success/failure, error code is sent. The sending content related to the scheme is consistent with the current playing information acquired by getvideolist (int roomid), and is serialized into a character string in a json format.
And S230, requesting a target carousel video from a Content Delivery Network (CDN) according to the carousel video identifier, and playing the target carousel video according to the time axis data so as to keep the target carousel video played by the client side and the current carousel video played by the live broadcast room in picture synchronization.
Specifically, the live broadcast server starts carousel, records and maintains a uniform play progress according to time lapse, for example, the nth video of the current list, and the xth minute of the video timeline, the client enters the live broadcast room and requests the server interface getvideolist (int roomid) to the live broadcast server to acquire the carousel state and the video source information. And then autonomously pulls the specified video from the interface getvideofile (int videoid) of the video file server and jumps to the specified timeline for playing. Keeping most clients watching at the same schedule. Therefore, the unified viewing progress of all the clients can be maintained as in live broadcasting, and the situation that the user A looks at the head, the user B looks at the tail, and the mutually-issued barrage content is unrelated and cannot interact with each other is avoided. If the user A looks at the first video and the user B looks at the second video, different users in the same live broadcast room cannot interact with each other, and to ensure that the users enter the live broadcast room to see the video contents on the same time line, the user inquires of the live broadcast server to request the second number of the video being watched, automatically pulls the second number of the video, and plays the video from the second, so that the users can see the same time line.
And the client side directly requests the video file, and the video file belongs to static resources and can be stored in the conventional CDN. The cost is much lower than the network cost and the server cost of live stream push. Meanwhile, under the condition of no user viewing, any computing resource and network resource are not consumed.
In addition, as shown in fig. 6, the video carousel system provided in the embodiment of the present application at least includes a live broadcast server, a content delivery network CDN, a main broadcast end, and a client, where the content delivery network CDN stores a carousel video to be played; it should be noted that the live broadcast/carousel/bullet screen server in fig. 6 may be integrated into the live broadcast server in the embodiment.
The client is used for sending a carousel request to the live broadcast server when the live broadcast room of the anchor terminal is switched from the live broadcast state to the carousel state;
the live broadcast server is configured to obtain carousel information according to a current carousel condition of the live broadcast room based on the carousel request, and send the carousel information to the client, where the carousel information includes: carousel video identification and timeline data;
the client is further configured to request a target carousel video from a content delivery network CDN according to the carousel video identifier, and play the target carousel video according to the time axis data, so as to keep the frames of the target carousel video played by the client and the current carousel video played in the live broadcast room synchronized.
Exemplarily, the content delivery network CDN includes a video file server and a network node; the carousel video to be played is stored in the video file server;
the client is also used for initiating a stream pulling request of a target carousel video to the video file server according to the carousel video identifier;

When the anchor end performs video live broadcasting, the current live broadcasting architecture still adopts the conventional stream pushing mode shown in fig. 1, but when the anchor end is switched from live broadcasting to carousel, the architecture is switched to the video carousel system architecture shown in fig. 6. When the anchor end plays the carousel video, the traditional video carousel system architecture shown in fig. 1 can be changed into the video carousel system architecture shown in fig. 6, so that the streaming cost required by the traditional carousel anchor regardless of whether the traditional carousel anchor is watched or not is avoided, the user actually watches the video file, and the streaming resource and the corresponding cost are saved. After that, when the anchor end is finished from the carousel and the carousel is switched to the live broadcast, the architecture is switched from the video carousel system architecture shown in fig. 6 to the conventional streaming mode shown in fig. 1, so as to ensure that the anchor end normally carries out the live broadcast.
