S102, searching a node adaptive to the live broadcast starting operation.
In a live platform, two or more nodes are configured, each implementing a specific function for providing video processing functions.
The node may be an independent device, such as a server, or an equipment cluster, such as a server cluster, where each device in the equipment cluster may provide the same function, or may be a function module in the equipment, which is not limited in this embodiment.
In a specific implementation, the functions of each node are unique and not repeated, and the functions of the nodes may be set by those skilled in the art according to actual situations such as resource occupation of the functions and relevance between the functions, and may be set as a series of processing performed on the video data, or may be set as a processing performed on the video data, which is not limited in this embodiment.
In one example, the node may include at least one of:
1、4K
in the 4K node, original video data with a resolution of 4K may be processed, and for this, the anchor user may use professional user equipment to acquire the original video data to achieve the resolution of 4K.
2. Ultra-minute
Super Resolution is Super Resolution (SR), generally, the performance of the user equipment is low, so that the Resolution of the original video data is low, for example, 1K, and in a Super Resolution node, the original video data with low Resolution can be mapped to the video data with high Resolution, so as to achieve the effect of enhancing the picture details.
3. Beauty treatment
In the node of beauty, the person image in the single-path original video data can be subjected to beauty operations, such as skin grinding and five sense organs (such as eyes, nose, lips and the like) adjustment.
4. Audio and video rotating and pushing device
In the audio/video forwarding node, the original video data may be decoded and encoded, so as to realize transcoding, and the transcoded video data is pushed to other devices, such as a CDN (Content Delivery Network).
5. Anchor white board
In the nodes of the anchor whiteboard, an area can be added in the original video data to serve as the whiteboard, writing handwriting uploaded by an anchor user through an anchor client is received, and the writing handwriting is written into the whiteboard, or bullet screen data received in the live broadcasting process is written into the whiteboard.
6. VR beauty
In the VR beauty node, a beauty operation, such as peeling, and adjusting five sense organs (such as eyes, nose, lips, etc.), may be performed on a character image in original video data in VR (Virtual Reality) form.
7. PK mixed picture
In a PK comic node, two or more original video data may be merged to enable two or more anchor users to compete simultaneously.
8. P2P slicing
In a live scene, video data is mostly transmitted by using a peer-to-peer (P2P) mode, and original video data is sliced into segments in nodes of a P2P slice.
Of course, the above nodes are only used as examples, and when implementing the embodiment of the present invention, other nodes may be set according to actual situations, for example, a node for live broadcasting (i.e., virtual live broadcasting) using one avatar, and the like, which are not limited in this embodiment of the present invention. In addition, besides the above nodes, those skilled in the art may also use other nodes according to actual needs, and the embodiment of the present invention is not limited to this.
In this embodiment, after receiving the live broadcast start operation, a node that realizes a function required by the live broadcast start operation can be searched from the live broadcast platform according to the demand of the live broadcast.
Further, if the node is a device cluster, a device that processes original video data may be selected from multiple devices according to a load balancing method or the like.
And S103, splicing the nodes into a link suitable for processing the original video data.
In this embodiment, each node may be configured according to the characteristics of the original video data, so that all nodes are spliced into a link suitable for processing the original video data.
The link means that each node has an order of processing the original video data to form a processed line, and of course, each node may maintain a long connection through HTTPS, and is not necessarily a physical connection.
In a specific implementation, the nodes may form a link in a serial manner or may form a link in a parallel manner, which is not limited in this embodiment.
For example, as shown in fig. 2A, A, B, C, D, E, F, G represents a node, and node a, node B, node C, node D, node E, node F, and node G are sequentially connected in series to form a link, where node a, node B, node C, node D, node E, node F, and node G sequentially process the original video data.
For another example, as shown in fig. 2B, A, B, C, D, E, F, G, H, I, J represents a node, and node a, node B, and node C are connected in series, and node F and node G are connected in series, and node D and node E connected in series are connected in parallel with node H, node I, and node J connected in series, thereby forming a link in which node a, node B, and node C sequentially process original video data, and the original video data output from node C is sequentially processed by node D and node E, and the original video data output from node D and the original video data output from node E are sequentially processed by node F and node G.
In one embodiment of the present invention, S103 may include the steps of:
and S1031, setting the positions of the nodes.
In this embodiment, the positions may be set for each node according to a preset specification, thereby determining the order of each node.
In one approach, the dependencies of the nodes on the technical implementation may be determined, such that the locations of the nodes are determined in accordance with the dependencies.
The so-called dependency relationship, that is, the processing of the original video data by the node B, depends on the processing of the original video data by the node a, and at this time, the position of the depended node is before the position of the depended node, that is, the position of the node a is before the position of the node B, that is, the node a preferentially processes the node B, so that the node B can normally implement the processing of the original video data.
For example, it is assumed that a node a is used to perform face detection on original video data and output face key points, and a node B is used to drive avatar change according to the key points to implement virtual live broadcasting, where the node B depends on the node a and the position of the node a is located before the position of the node B.
In another mode, constraint relations of the nodes on the business are determined, and the positions of the nodes are determined according to the constraint relations.
The constraint relationship is to constrain the processing of the original video data by the node according to the service requirement.
For example, in order to implement a push stream service in a live scene, the audio/video forwarding node is constrained to the last position, that is, other nodes are all located before the audio/video forwarding node.
For another example, the position of the beautifying node is constrained before the position of the PK comingled node, so that the original video data is firstly subjected to the beautifying operation and then merged with other original video data, and the quality of the beautifying operation is ensured.
In the embodiment, the positions of the nodes are set through the dependency relationship and the constraint relationship, so that no conflict is generated between the nodes, and the situation that the original video data is processed due to the conflict is avoided, thereby ensuring the normal processing of the original video data.
Of course, the above manner of determining the node position is only an example, and when implementing the embodiment of the present invention, other manners of determining the node position may be set according to actual situations, which is not limited in this embodiment of the present invention. In addition, besides the above-mentioned manner of determining the node position, a person skilled in the art may also adopt other manners of determining the node position according to actual needs, and the embodiment of the present invention is also not limited thereto.
S1032 initializes the nodes by location with respect to the original video data to form a link.
After determining the location of the node, on the one hand, the node is configured according to the location, and on the other hand, the node is configured for the processing requirements of the original video data, thereby forming a link suitable for processing the original video data.
In a specific implementation, each node may be traversed, and for a current node, configuration information is generated for original video data, where the configuration information stores parameters for processing the original video data, and the parameters may specifically include the following parameters:
1. input source
By input source, we mean the source of the original video data to be processed by the current node.
For the current node, the node whose position is before the current node can be determined, and the node before the current node (such as information representation of device ID, host number and the like) is written into the configuration information as an input source.
Further, for a node whose location is first, its input source may be empty, or set as a CDN node for receiving raw video data of an anchor client, a streaming server for collecting raw video data, and so on.
For example, as shown in fig. 2A, the input source of node B is node a, the input source of node C is node B, the input source of node D is node C, the input source of node E is node D, the input source of node F is node E, and the input source of node G is node F.
2. Operating parameters
The operation parameter may be a parameter for processing the original video data by the current node, for example, for a beauty node, the operation parameter may include a beauty object (such as eyes, nose, lips, etc.), a beauty amplitude, etc., and for a PK comingled node, the operation parameter may include a background, a duration, etc.
And for the current node, extracting operation parameters from the live operation of the anchor client, and writing the operation parameters in the live operation into the configuration information.
3. Output target
By input source, we may refer to the destination of the original video data after the current node has completed processing.
For the current node, the node with the position behind the current node can be determined, and the node behind the current node (such as information representation of device ID, host number and the like) is written into the configuration information as an output target.
Further, for a node with a position at the end, the output target is empty, or the node is set as a CDN node, and the CDN node is configured to push target video data to a viewer client that a viewer user logs in.
For example, as shown in FIG. 2A, the output of node A targets node B, the output of node B targets node C, the output of node C targets node D, the output of node D targets node E, the output of node E targets node F, and the output of node F targets node G.
And S104, in the link, sequentially calling the nodes to process the original video data to obtain target video data.
After receiving the original video data, the original video data may be input into a link, in which nodes are sequentially called in order, and the original video data is processed according to a logic processed by the nodes themselves, thereby outputting target video data.
In a specific implementation, in the link, configuration information of each node may be read, the configuration information including input source, operating parameters, output target.
And receiving the original video data from the node corresponding to the input source, and processing the original video data according to the operation parameters.
If the node is a node which is not the last node, outputting the processed original video data to a node corresponding to an output target;
and if the node is the last node, outputting the processed original video data as target video data.
And S105, releasing the target video data in the live broadcast room corresponding to the anchor client.
In this embodiment, a anchor user who logs in at an anchor client may be determined, the anchor user sets a live broadcast room, after target video data is generated, the target video data may be released in the live broadcast room, and when a viewer client of a viewer user loads a page of the live broadcast room, the target video data may be pulled from a CDN node and played on the page.
In this embodiment, a live broadcast start operation and original video data sent by an anchor client are received, a node adapted to the live broadcast start operation is searched, each node is used for providing a video processing function, the nodes are spliced into a link suitable for processing the original video data, the nodes are sequentially called in the link to process the original video data, target video data are obtained, and the target video data are released in a live broadcast room corresponding to the anchor client.
Firstly, the video processing function is transferred from the front-end user equipment to the back-end live broadcast platform, so that the calculation amount of the front-end user equipment is reduced, and the performance of the front-end user equipment is improved.
Secondly, nodes in the back-end live broadcast platform form a frame for processing the streaming media, and more devices with higher computing performance, such as servers and the like, are used, so that not only can the functions of the front-end user equipment, which cannot be realized due to the limited performance, be increased, and the diversity of the functions be increased, but also more complex and better algorithms can be used for improving the effect of the functions aiming at the functions realized by the front-end user equipment.
Moreover, the technical personnel has stronger control on the back-end live broadcast platform than the front-end user equipment, when the functions of the client side are updated or the BUG (BUG) of the client side is repaired, the corresponding nodes are newly added or updated, the modification to the client side is little or even no modification, the client side of the whole network is not required to be updated, the flexibility is high, and the cost is low.

After the original node is deleted, the link continues to process the original video data, outputs the target video data, and issues the target video data with the original function deleted in the live broadcast room.
For example, as shown in fig. 7A, a node B, a node C, a node D, a node E, a node F, and a node G are sequentially connected in series to form a link, and a node that implements a function required for a third operation triggered by an anchor user is a node D (a dashed box in fig. 7A), that is, the node D is a third target node, then, as shown in fig. 7B, in the node D, configuration information generated for current original video data is deleted, in the node C, an output target in the configuration information is modified from the node D to the node E, in the node E, an input source in the configuration information is modified from the node D to the node C, and at this time, the original video data is sequentially processed according to the sequence of the node a, the node B, the node C, the node H, the node E, the node F, and the node G.
In this embodiment, the third operation sent by the anchor client is received, a node adapted to the third operation is searched for and serves as a third target node, and the third target node is deleted in the link, so that the control of the anchor user on live broadcast is realized, and the normal operation of live broadcast is ensured.
EXAMPLE five
Fig. 8 is a flowchart of a live broadcasting method according to a fifth embodiment of the present invention, where the present embodiment is based on the foregoing embodiment, and further adds processing operations of playback and live broadcasting stop, where the method specifically includes the following steps:
s801, receiving live broadcast starting operation and original video data sent by a main broadcast client.
S802, searching a node adaptive to the live broadcast starting operation.
Wherein each node is configured to provide video processing functionality.
And S803, splicing the nodes into a link suitable for processing the original video data.
And S804, selecting the nodes meeting the echoing conditions from the links as reference nodes.
And S805, sending the original video data output by the reference node to the anchor client for playing.
In this embodiment, a loopback condition may be preset, and if a node in the link meets the loopback condition, the node may be determined to be a reference node.
Generally, the echoing condition is that the function of interest to the anchor user, and the function of the node located behind the reference node, is not of interest to the user and in some cases, may be ignored.
In one example, if the condition of the redisplay is beauty, the last node for beautifying the character image may be set as the reference node.
In another example, if the echo condition is comic, then the node of the PK comic may be set as the reference node.
Of course, besides the default setting of the playback condition, the functions of the nodes in the link may be displayed on the UI of the anchor client, and when the anchor user selects a certain function, the function may be set as the playback condition, and the corresponding node is set as the reference node, and so on
One path of original video data output by the reference node is transmitted to the anchor client, and the anchor client plays the original video data, so that the anchor user can conveniently watch at least part of processing effects of the link.
Generally speaking, the reference node is a node which is not the last node in the link, and before the link is processed, the original video data in the intermediate processing process is sent to the anchor client for playing, so that the anchor user can preview the processing effect of the link in advance, the time delay of playback is reduced, and the efficiency of live broadcasting is improved.
For example, as shown in fig. 9A, a node B, a node C, a node D, a node E, a node F, and a node G are sequentially connected in series to form a link, the anchor client 900 uploads the original video data to the link for processing, the node that actually meets the playback condition is the node E (a dashed box in fig. 9A), that is, the node E is a reference node, and as shown in fig. 9B, one path of the original video data processed by the node E is transmitted to the node F for processing, and the other path is transmitted to the anchor client 900 for playing.
And S806, in the link, sequentially calling the nodes to process the original video data to obtain target video data.
And S807, releasing the target video data in the live broadcast room corresponding to the anchor client.
And S808, receiving live broadcast stopping operation sent by the anchor client.
And S809, responding to the live broadcast stopping operation, and deleting the link.
The anchor client displays a control for stopping live broadcasting on the UI, when the live broadcasting is finished, an anchor user can trigger the control for stopping starting, so that the live broadcasting stopping operation is triggered, the live broadcasting platform is informed, in addition, the user equipment where the anchor client is located stops calling modes such as a camera, a microphone and a screen recording mode, and the original video data is stopped being generated.
And after receiving the live broadcast stopping operation, the computer equipment in the live broadcast platform deletes the link established for the original video data and releases resources.
In a specific implementation, the configuration information generated for the original video data may be deleted in all nodes in the link, and certainly, the configuration information generated for other original video data is not deleted, so that the node remains in other links and processes other original video data.
