Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
It should be understood that the described embodiments are only some embodiments of the invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In a first aspect, an embodiment of the present invention provides a live broadcast method, which can forward a live video broadcast in a pull address, and provide a pull service to a viewer end by using multiple CDN service vendors, so as to effectively improve disaster recovery performance of live network broadcast.
As shown in fig. 1, a live broadcasting method provided by an embodiment of the present invention may include:
s11, acquiring a live original pull stream address;
specifically, the live broadcast in this embodiment is based on a CDN network, and a live video recorded by a main broadcast end is uploaded to a CDN stream pushing node and buffered to a stream pulling node closest to a viewer end through the CDN network, so that the viewer end pulls a live stream from the closest stream pulling node to view a corresponding live video. The original pull stream address in this step is an address for providing corresponding live video for the audience terminal on the CDN edge node closest to the audience terminal. The node corresponding to the address may provide a live video stream to a plurality of viewers at the same time, and each viewer corresponds to one live video stream.
S12, pushing the live streaming with the preset number in the original streaming addresses to the target streaming addresses to form an updated streaming address list; the target pull flow address and the original pull flow address belong to different CDN manufacturers of a content delivery network;
in the step, live streaming addresses are changed or expanded, and a preset number of live streams provided for audience terminals in CDN nodes at the original streaming addresses are pushed to target streaming addresses different from CDN manufacturers at the original streaming addresses, so that an updated streaming address list is formed. The number of live streams to be forwarded and pushed can be set and adjusted as required, and the live streams can only relate to a part of live streams in the original pull stream address and can also relate to all live streams in the original pull stream address. Optionally, according to specific needs, the number of the destination pull stream addresses may be one or more, and the corresponding CDN vendors may be one or more than one, as long as the CDN vendors are different from the CND vendors to which the original pull stream addresses belong, which is not limited in this embodiment of the present invention.
And S13, when the audience pulls to watch the live broadcast, the updated pull address list is provided for the audience so that the audience pulls to watch the live broadcast from the updated pull address.
In this step, when the viewer pulls the stream, an updated pull stream address list can be provided to the viewer, and the viewer can select a pull stream address from the updated pull stream address list to watch the live video.
The live broadcasting method provided by the embodiment of the invention can push the live broadcasting streams with preset number in the original stream addresses to the target stream addresses, and the original stream addresses and the target stream addresses provide the live broadcasting streams to all audience terminals together. Therefore, as the original pull stream address and the target pull stream address belong to different CDN manufacturers respectively, even if the CDN pull stream service provided by one CDN manufacturer fails, a part of audience can still continuously watch the live video through the pull stream service provided by other CDN manufacturers, the condition that all audience ends cannot watch the live video can not be caused, and the disaster tolerance performance of the live network is greatly improved.
Optionally, the live broadcast in the embodiment of the present invention may include a situation of a main broadcast unicast, or a situation of an interactive live broadcast of a main broadcast viewer, and the embodiment of the present invention does not limit this. Particularly, for the interactive live broadcast of the anchor and the audience, the anchor and the audience need to provide corresponding support for the anchor end and the streaming end node served by the CDN to perform the live-talk interaction, so that the number of CDN manufacturers that can meet the requirements is greatly reduced, and the disaster tolerance is greatly reduced. In view of this, in some embodiments of the present invention, when selecting a suitable CDN manufacturer for the anchor side, more CDN manufacturers may provide corresponding pull service for the audience side together through live stream forwarding, so as to distribute risks, thereby greatly improving the disaster tolerance performance of the pull side.
Specifically, in step S11, the cloud service end may learn, through a live broadcast request sent by the anchor end, which CDN service provider the live video recorded by the anchor end is delivered through, and select, according to the position of the viewer end, one pull flow node closest to the viewer end from the pull flow nodes deployed by the CDN service providers as an original pull flow node, where the corresponding address is an original pull flow address, so as to learn an original pull flow address of a live stream.
After the original pull stream address is obtained, in step S12, the preset number of live streams in the original pull stream address may be pushed to other pull stream addresses, that is, destination pull stream addresses, through the intermediate node. The intermediate node may be various devices or servers for forwarding the live stream from one pull address to another, etc. The number of the intermediate nodes may be one or more, and the embodiment of the present invention does not limit this.
Specifically, in an embodiment of the present invention, pushing, by an intermediate node, a preset number of live streams in the original pull stream address to a destination pull stream address may include: pulling the live stream from the original stream pulling address through an intermediate node; under the condition that the intermediate node successfully pulls the live stream, indicating a target stream pulling address corresponding to the live stream to the intermediate node; and pushing the pulled live stream to the target pull stream address through the intermediate node.
That is to say, the cloud server may transmit the obtained original streaming address to the intermediate node, and the intermediate node may pull the video stream from the original streaming address to the intermediate node after receiving the original streaming address. And the intermediate node can report the pull state to the cloud server at any time, if the intermediate node successfully pulls the video stream, the cloud server can send a target pull address to the intermediate node, and after receiving the target pull address, the intermediate node can push the pulled video stream to the target pull address. Of course, in other embodiments of the present invention, the cloud server may also notify the intermediate node of the original pull stream address and the destination pull stream address, and the intermediate node directly performs pull and push of the live stream. The embodiments of the present invention are not limited thereto.
Optionally, in various live video broadcasts, each intermediate node may pull and push multiple live streams simultaneously. These pulls and pushes may succeed or may fail. In an embodiment of the present invention, in a case that the intermediate node fails to push the live stream, it may be detected whether the anchor end finishes live streaming; and under the condition that the live broadcasting is not finished by the anchor terminal, the live broadcasting stream can be continuously pushed through the intermediate node. Optionally, in the forwarding process, one intermediate node performing the forwarding may be always kept unchanged, or one intermediate node may be switched to another intermediate node, which is not limited in the embodiment of the present invention.
For example, in an embodiment of the present invention, the anchor uploads the live video, the original pull stream address is add1, and the live video is copied and pushed to the destination pull stream address add2 by performing live broadcast forwarding through the intermediate node M1. And the intermediate node M tries to transfer and push failure after a period of time and reports the transfer and push failure to the cloud server. The cloud server discovers that the anchor does not actively terminate the live broadcast, and instructs the intermediate node M to try to pull the stream from add1 and push to add2 again. If the forwarding of the intermediate node M still fails, the cloud server may instruct the intermediate node to repeat the forwarding after a preset time interval, for example, a fibonacci number of seconds. Or, the cloud server may instruct the intermediate node N to replace the intermediate node M to perform the forwarding operation.
When the fact that the anchor end finishes live broadcasting is detected, the cloud server end can inform the intermediate node to stop corresponding pull flow and push work.
Further, because the original streaming addresses, the destination streaming addresses, and the intermediate nodes are numerous and are interlaced into a network, in order to make the distribution of the streaming more reasonable and make the load of each intermediate node balanced, according to an embodiment of the present invention, the live broadcasting method provided in the embodiment of the present invention may further include: receiving node load information reported by the intermediate node; and scheduling the intermediate nodes which carry out the forwarding and pushing operation according to the node load information so as to balance the load of the intermediate nodes.
For example, the intermediate node P1 is responsible for pushing both a live stream with the original pull stream address add3 to the destination pull stream address add4 and a live stream with the original pull stream address add5 to the destination pull stream address add 6. The intermediate node P1 may report the forwarding states of the two live streams and the load information of the intermediate node P1, such as the CPU utilization, to the cloud server at regular time. If the CPU utilization of the intermediate node P1 is 80% and the CPU utilization of another intermediate node P2 is 30%, the cloud server may transfer a part of the forwarding tasks of the intermediate node P1 to the intermediate node P2 to complete, so as to reduce the workload of the intermediate node P1, and make full use of the intermediate node P2, so that the whole forwarding system is more balanced.
The above mainly describes how to push the live stream at the original pull address to the destination pull address through the intermediate node. However, for the viewer, after such a transition, the address of the live stream obtained by the viewer changes, and in order to view the live video program smoothly, the viewer needs to obtain the pull stream address after the transition. For this reason, in step S13, when the viewer end pulls to watch the live broadcast, the updated pull address list needs to be provided to the viewer end.
Specifically, in one embodiment of the present invention, when the viewer end pulls the live broadcast, the step of providing the updated pull address list to the viewer end may comprise the steps of:
receiving a pull stream request of a viewer end, wherein the pull stream request carries a live broadcast video identifier of a live broadcast to be watched;
determining an updated pull stream address list corresponding to the live broadcast to be watched by the audience according to the live broadcast video identifier;
and providing the updated pull stream address list to the audience.
For example, in an embodiment of the present invention, the viewer T1 wants to watch a video live a, the address of the original stream of the video live a is addA1, and after the live video a at addA1 is pushed, a part of the live stream of the video live a is pushed to addA 2. The viewer end T1 sends a pull stream request to the cloud server end, and the pull stream request carries a live video identifier A of a live broadcast to be watched. The cloud server may determine that after the pull stream forwarding is performed according to the live video identifier a, the updated pull stream address list includes the original pull stream address addA1 and the destination pull stream address addA2, and then send the updated pull stream address list to the viewer T1, so that the viewer T1 obtains the corresponding live video according to the updated pull stream address addA1 or addA2 in the list.
Optionally, in the embodiment of the present invention, one or more pull addresses included in the updated pull address list may be included, which is not limited in the embodiment of the present invention. When the updated pull stream address list includes a plurality of pull stream addresses, determining, according to the live video identifier, an updated pull stream address list corresponding to a live broadcast to be watched by the viewer, may further include:
determining a plurality of updated pull stream addresses corresponding to the live broadcasts to be watched by the audience according to the live video identification;
and sequencing the plurality of updated pull stream addresses according to a preset rule to form an updated pull stream address list.
Thus, a priority order can be provided for a plurality of pull stream addresses, and the pull stream address arranged in the front can be preferentially used by the audience. Optionally, the preset rule for sorting the pull stream addresses may be formulated according to the user level of the audience user, the service characteristics of the CDN service manufacturer, and the like. For example, in an embodiment of the present invention, a periodic charging of a CDN service provider may be used as a preset rule, and when a usage duration or a usage traffic distance of a certain pull address is smaller than a preset threshold, the priority of a pull address corresponding to the CDN service provider may be reduced, so that a viewer selects another pull address preferentially, thereby balancing pull distribution resources of multiple CDN providers, dynamically adjusting a gradient gear according to a charging mode of the CDN provider, effectively reducing a cost in unit time, and improving a performance-to-price ratio.
The live broadcast method provided by the embodiment of the invention is explained in detail by the specific embodiment.
As shown in fig. 2, the live broadcasting method provided by this embodiment may include the following steps:
s201, a main broadcasting end sends a live broadcasting request to a first front-end server;
s202, the first front-end server determines that the main broadcasting end meets the wheat connecting condition according to the live broadcasting request and informs a dispatching server;
s203, the scheduling server provides a CDN manufacturer for the anchor end scheduling and returns the CDN manufacturer to the first front-end server;
s204, the first front-end server returns the CDN manufacturer to the anchor end;
s205, the anchor informs the first front-end server to start streaming;
s206, the first front-end server transmits the video ID (vid), the anchor IP address (IPclientip) and the stream pulling address (such as pull-url and/or hls-url) to the dispatch server;
s207, the dispatching server returns to the first front-end server 200 to indicate that the data receiving is successful, or returns 400 to indicate that the data receiving is failed;
s208, the dispatching server receives the live address of the microphone and stores the address in a local system, and meanwhile, the dispatching server calls a transfer-push central control server interface;
s209, forwarding and pushing the asynchronous script of the central control server to call a source station (namely an intermediate node) for forwarding and pushing;
specifically, the forwarding and pushing center control server may notify the source station of the original pull stream address, the source station callback (callback) returns to the forwarding and pushing center control server to notify the pull stream state, and if the pull stream is successful, the forwarding and pushing center control server notifies the source station of the destination pull stream address (or called forwarding address).
S210, the source station reports a forwarding state to a forwarding central control server;
s211, if the forwarding is successful, the forwarding central control server calls a scheduling server to modify the pull stream address of the live broadcast;
specifically, the modified pull flow address list includes an original pull flow address and a destination pull flow address, and the original pull flow address and the destination pull flow address belong to different CDN service vendors. Optionally, the pull list may be ordered according to a preset rule, for example, according to a probability allocated to each CDN vendor, where for example, a CDN vendor with a probability of 95% ranks the first bit, and a CDN vendor with a probability of 5% ranks the second bit.
S212, if the forward push fails, the source station is informed to continue the forward push as long as the anchor end does not finish the live broadcast until the forward push succeeds;
s213, the source station reports the push-forward keep-alive information and the source station node load information of each path to the push-forward central control server;
s214, the forwarding and pushing central control server schedules the source station according to the node load information of the source station, for example, the address of the source station for next forwarding and pushing is judged;
s215, the second front-end server receives a pull stream request sent by a viewer, wherein the pull stream request carries a live broadcast video identifier to be watched;
s216, the second front-end server informs the scheduling server of the stream pulling request;
s217, the dispatching server sends the updated pull flow address list to the second front-end server;
s218, the viewer side pull-down page acquires the updated pull stream address list, pulls the live stream from the pull stream address in the pull stream address list and watches the live stream;
s219, the anchor terminal calls a first front-end server interface to finish live broadcasting;
specifically, in this step, the first front-end server stores the address of the live broadcast after the microphone connection is completed, asynchronously calls the interface of the scheduling server, transmits the live broadcast after the microphone connection is completed to the scheduling server, and the scheduling server returns to the front-end server 200 or 400 to indicate that the data reception is successful or failed; the dispatching server receives the live broadcast, stores the live broadcast in the local system, starts a script to call a transfer push central control server interface, and the transfer push central control system informs the source station to stop retrying pull stream and transfer push.
It should be noted that the first front-end server, the scheduling server, the forwarding and pushing central control server, and the second front-end server all belong to a cloud server, and in this embodiment, the cloud server is divided into the servers for analyzing the forwarding and pushing process to be described. The first front-end server and the second front-end server can be the same server or different servers, the first front-end server is close to the main broadcasting end, and the second front-end server is close to the audience end.
