Referring to fig. 2, fig. 2 is a schematic flow chart of a method for controlling playing of live video, which is applied to a live server, and the specific flow of the method for controlling playing of live video can be as follows steps 101 to 106:
101, acquiring user information of a live audience in response to an event that the live audience enters a target live room.
In the embodiment of the application, the user information of the live audience comprises user identification information and user IP address information. For example, the user information includes user identification information and user IP address information for indicating an area to which the user IP belongs, such as a south-china patch in guangzhou, guangdong. The computer device may obtain user information of a live audience in response to an event that the live audience enters a target live room.
102, Controlling the first CDN platform to establish connection with the live broadcast server and the live broadcast audience terminal of the live broadcast audience respectively based on the user information.
In the embodiment of the present application, the first CDN platform may be controlled to establish connection with the live server and the live audience side of the live audience, respectively, based on the user information, where a content delivery network (i.e., CDN) refers to a set of servers distributed in each region. These servers store copies of the data so that the servers can satisfy requests for data based on which servers are closest to the user.
103, Sending a target live stream to the live audience terminal through the first CDN platform so as to display live videos corresponding to the target live stream on a live interface provided by the live audience terminal.
Specifically, the live broadcast server sends a target live broadcast stream to the live broadcast audience terminal through the first CDN platform so as to display live broadcast videos corresponding to the target live broadcast stream on a live broadcast interface provided by the live broadcast audience terminal.
104, Receiving a live stream video request sent by a second CDN platform, wherein the live stream video request is determined by the second CDN platform based on a live stream address of the target live stream sent by the live audience terminal.
The live stream address is a pull stream address, and a specific form can be a stream address of xx.com/xxx.flv.
And 105, controlling the second CDN platform to respectively establish connection with the live broadcast server and the live broadcast audience terminal, and triggering the second CDN platform to distribute target CDN nodes for the live broadcast audience terminal.
In an embodiment, after the step of "controlling the second CDN platform to establish a connection with the live server and the live viewer side, respectively," the method may include:
And sending the user information of the live audience to the second CDN platform so as to trigger the second CDN platform to distribute target CDN nodes for the live audience terminal based on the user IP address information.
Specifically, the second CDN platform allocates, as a target CDN node, a CDN node closest to the user IP address information of the client of the live audience based on the user IP address information.
106, Based on the live stream video request, transmitting a copy live stream of the target live stream to the second CDN platform, and transmitting the copy live stream to the live audience terminal through a target CDN node configured by the second CDN platform for the live audience terminal, so that the live audience terminal performs live stream control based on the target live stream, the copy live stream and preset live stream switching logic.
In an embodiment, after the step of "sending the replicated live stream of the target live stream to the second CDN platform based on the live stream video request", the method may include:
If a live stream pulling failure result returned by the second CDN platform is received, continuously sending a target live stream to the live audience terminal through the first CDN platform so as to display live videos corresponding to the target live stream on a live interface provided by the live audience terminal.
In another embodiment, after the step of "sending the replicated live stream of the target live stream to the second CDN platform based on the live stream video request", the method may include:
if the prompt information of the target CDN live stream forwarding failure result returned by the second CDN platform is received, the target live stream is continuously sent to the live audience terminal through the first CDN platform so that live videos corresponding to the target live stream can be displayed on a live interface provided by the live audience terminal.
For example, when the prompt information of the target CDN live stream forwarding failure result returned by the second CDN platform is detected, it is determined that a scenario in which switching of the third CDN fails occurs, and the target live stream is continuously sent to the live audience through the first CDN platform, so that live video corresponding to the target live stream is displayed on a live interface provided by the live audience. Specifically, when a pulling failure, a pulling error, a coding error, a hardware error or a network timeout and the like are detected, determining a target CDN live stream forwarding failure result.
For another example, when the prompt information of the abnormality of the target CDN node returned by the second CDN platform is detected, the target live stream is continuously sent to the live audience through the first CDN platform, so that a live video corresponding to the target live stream is displayed on a live interface provided by the live audience. Specifically, when the situation that the CDN node is empty and the CDN node return stream address does not meet url specifications or the like is detected, at this time, the target CDN node cannot send the copy live stream to the live client, so that the target live stream is continuously sent to the live audience through the first CDN platform, so that live video corresponding to the target live stream is displayed on a live interface provided by the live audience.
Optionally, after the step of "sending the replicated live stream of the target live stream to the second CDN platform based on the live stream video request", the method may include:
receiving a live stream forwarding rate sent by the second CDN platform;
and managing each CDN node in the second CDN platform based on the live stream forwarding rate and a preset threshold.
Specifically, in the step of managing each CDN node in the second CDN platform based on the live stream forwarding rate and a preset threshold, the method may include:
if the live broadcast stream forwarding rate is lower than a first preset threshold, controlling each CDN node in the second CDN platform to pause use, controlling a server of the second CDN platform to establish connection with a live broadcast audience terminal, and triggering the server of the second CDN platform to send the copy live broadcast stream to the live broadcast audience terminal so that the live broadcast audience terminal can conduct live broadcast stream control based on the target live broadcast stream and the copy live broadcast stream and preset live broadcast stream switching logic.
And if the live stream forwarding rate is higher than a first preset threshold, controlling the second CDN platform to respectively establish connection with the live server and the live audience terminal, and triggering the second CDN platform to allocate a target CDN node for the live audience terminal.
For example, the first preset threshold may be set to 50%, if the live stream forwarding rate is lower than 50%, the aggregation of the segments CDN nodes may be started, for example, the granularity of the segments is reduced, and the segments are returned to the root CDN server, although communication with too large cross segments may cause delay increase, the sharing rate may be increased, so that the cost is reduced, specifically, the suspension of use of each CDN node in the second CDN platform may be controlled, the connection between the server of the second CDN platform and the live audience terminal may be controlled, and the server of the second CDN platform may be triggered to send the replicated live stream to the live audience terminal, so that the live audience terminal may perform flow control based on the target live stream and the replicated live stream, and a preset live stream switching logic. And if the live stream forwarding rate is higher than 50%, controlling the second CDN platform to respectively establish connection with the live server and the live audience terminal, and triggering the second CDN platform to distribute target CDN nodes for the live audience terminal.
Further, if the live stream forwarding rate is higher than the second preset threshold value by 95%, that is, the live stream forwarding rate has reached the ideal stage, the aggregate slice granularity can be increased, and the instantaneity is improved, specifically, the range of the slices responsible for each cdn can be reduced, so that each cdn is only responsible for forwarding the live stream in a small area, the forwarding rate in the area is improved, and the forwarding rate of the live stream is increased cdn to send the live stream.
In a specific embodiment, when a user is detected entering the target live room, the host stream is pulled, and the user identity and the region to which the ip belongs (e.g., guangzhou, guangdong, south China) are identified, where "host stream" refers to the video stream of the host in the target live room, "pull host stream" refers to the request to pull the video stream of the host (i.e., the video stream has not been pulled yet), and "identify the user identity, the region to which the ip belongs" is used later in distributing the tile cdn, identify the user identity, i.e., determine the user uuid, user browser, user ip address, user network [ 4g, mobile, etc.), the user's system, and the user bandwidth.
Then, a third party connection cdnA is established, the user a starts playing the third party cdnA source stream a, and when the third party connection cdnA is established as soon as the user enters the live broadcasting room, the third party connection is a request for streaming, the third party cdnA source stream a refers to the host stream, and the "user a starts playing the third party cdnA source stream a" refers to playing the video stream of the live broadcasting room host acquired from the third party cdnA platform. Third party connection a is a source flow provider and third party cdnB is a copy party.
Then, the third party cdn B starts to report the stream address and information such as user IP through the user a, starts the mobile zone server, starts to preheat, and pulls the third party source stream a. Specifically, the location information may be obtained according to the user ip, and the server location closest to the location may be obtained according to the location information, so as to distribute the user to connect to the server, thereby increasing the communication smoothness and reducing the delay. The "preheating" means that each of the fragment servers is in a service suspension state when no user accesses, and when user traffic comes in, the fragment servers start to start services, and the fragment servers have large concurrency and trigger elastic capacity expansion. Since the third party cdnB cannot be directly accessed at first, since the third party cdnB may or may not have a source stream (depending on whether other users have previously pushed the stream address to the third party cndB), if not, the third party cdnB is connected by the incoming call, failure is possible, and then the third party source stream a is re-connected, which may cause the user side to be left blank too long, so the third party cdnA is connected first, then the third party cdnB is requested to obtain whether there is a stream, and then the third party cndB is switched seamlessly. Third party cdnB begins pulling host flow a and distributes to third party cdn servers of third party cdnB. The third party cdnB has a plurality of third party cdn servers, and the granularity can be adjusted according to the regional division, for example, when the user platform is more, such as jittering, the third party cdn servers can be cut into the city, so that each city level server serves the users in the whole city, if the cardinality is small and scattered, the granularity can be adjusted to be national, and one national server serves all people, so that the sharing rate can be improved, but some communication quality can be reduced.
Then, the user side starts to request the third party cdnB for each segment cdn node condition and reports the player condition and the use condition. The region can be contracted and adjusted, such as the region of the city, province, and south China. Reporting to the third party cdnB, the third party cdnB can be informed of the current push quality, whether there is any problem of jamming or communication. Use cases such as fps of the pull stream, the speed of the downstream bandwidth. Since there is a possibility that the service of the present patch node is not valid, it is necessary to connect the nodes of the partition wall patches, and each patch cdn node is determined.
And then, when the section cdn node is ready, the user side starts to pull the third party copy stream, the third party copy stream and the third party copy stream are compared with each other in dts, and stream switching is performed at the position where dts is close to a key frame within 10 frames, so that seamless switching is achieved. Wherein the third party copy stream is the source stream and the plug party is the third party cdnB. The concept of the time domain of dts compares whether two streams, the third party copy stream and the video stream currently being played by the user client, come to an adjacent frame number. The comparison duration may be within 10 frames and a gap within 60 frames. Since approximately 4-5 frames of the video will be interspersed with one key frame, the switch may be to a key frame position within approximately 10 frames. If the client side of the living broadcast room does not have video to play at the moment, the third party copy stream is directly used.
If the third party cdn fails to switch, the spam switches back to the host flow, and the third party cdn may fail in case of a failure in pulling, a failure in encoding and decoding, a failure in hardware reporting, and a timeout in the network. If the cdn node condition of the third party cdnB returns an exception, the host flow is switched back. For example, the cdn node is empty, the cdn node return stream address does not conform to url specification, and the like, so that the cdn node cannot send the third party copy stream to the user side, and the cdn node condition is determined to return an exception. Based on the above-mentioned knowledge, if the user side normally receives the third party copy stream, switching the stream, and playing the third party copy stream at the client side of the user side; if the third party cdnB is failed to switch or the cdn node returns an abnormality, the host stream is switched back, and the host stream is played at the client side of the user.
Further, the platform service starts to count the usage rate of the third party forwarding flow, if the forwarding rate is not ideal, for example, less than 50%, starts to aggregate the cdn nodes of the patch, for example, reduce the granularity of the patch, return the source to the root cdn server, and perform too large communication across the patch, which may cause delay increase, but increase the sharing rate and reduce the cost. If the sharing rate reaches an ideal stage, such as 95%, the granularity of the aggregation segment can be improved, and the instantaneity is improved. Wherein the platform service refers to a server of the live platform,
The "third party forwarding flow" refers to the "third party copy flow" forwarded to the user side, the forwarding rate refers to the success rate of the "third party copy flow" forwarded to the user side, and the "aggregate patch cdn node" refers to reducing the granularity, amplifying the patch, and aggregating more people. The patch granularity refers to the patch range of adjusting the city, province, south China and north China, the source returning to root cdn server specifically refers to the domestic platform, the source tracing to root is the root node of the national level, namely domestic users all use the same server. Specifically, if the forwarding rate of the third party cdnB is lower than 50%, the use of cdn in each region associated with the third party cdnB is suspended, and the server of the third party cdnB is directly used to transmit the host stream. If the forwarding rate is higher than 50% and lower than 95%, the use of cdn in each area associated with the third party cdnB is started to transmit the host flow according to cdn in the corresponding area where the IP of the user a is located. If the forwarding rate is higher than 95%, the scope of the area responsible for each cdn is reduced, so that each cdn is only responsible for forwarding the host stream in a small area, the forwarding rate of the area is improved, and a new cdn is added to send the host stream.
Based on the above, when the user a enters the live broadcast room of the first anchor through the client, the host stream of the first anchor is obtained from the third party a, and the live broadcast video corresponding to the host stream of the first anchor is played on the graphical user interface provided by the client of the user a. At the same time as the above steps occur, the client of the user a also sends the stream address of the host stream and the IP information of the user a to the third party cdnB, so that the third party cdn B of the third party pulls the third party source stream a (i.e. the host stream of the first host), and after the third party B pulls the host stream of the first host, the client of the user a is allocated to the server of the third party B closest to the user a according to the IP address of the user a cdn. When cdnB of the third party obtains the hosting stream of the first anchor, the client of the user a pulls the hosting stream of the first anchor to cdnB of the third party B, and switches the hosting stream video being played by the user a at this time through the third party a to the hosting stream sent by cdnB of the third party B, and disconnects the connection with the third party a. If the switch to the video provided by cdn of the third party B fails, then the connection with the third party cdnA is continued, and the host stream of the first anchor provided by the third party cdnA is played. Because of the cost involved, some cdn have high bandwidth costs and some are low, the platform needs to migrate to use cdn at low cost, so to save cost, switch to third party cdnB to push the hosting video of the hosting stream of the first host to the user side for playback. The third party cdnA only needs to accept the push stream of the anchor and provide the host stream, the third party cdnB has low cost, only needs the copy stream of the third party, does not relate to high-performance behaviors such as encoding and decoding, and the like, and can be pushed to a plurality of user sides of a live broadcasting room for watching the anchor on a large scale.
In the embodiment of the application, the client of the server does not need to dock the third party cdn, and the core of the method is to multiplex one of the existing third party cdn flows X to push to a new third party, and the third party copy and provide services, so as to realize a cdn scheme for realizing low-cost seamless access to the third party source flow in live broadcast, reduce the docking development cost of the transmission server and the third party cdn, enable the third party client to access the third party cdn with minimum cost, and realize no perception of users.
