Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.
Referring to fig. 1, fig. 1 is a schematic view illustrating an interactive scene of a live broadcast system provided in the present application, which may be a live broadcast platform for live broadcast such as internet in some embodiments. The live broadcast system can comprise a server, a live broadcast initiating terminal and a live broadcast receiving terminal, wherein the server can be communicated with the live broadcast receiving terminal and the live broadcast initiating terminal respectively, and the server can provide live broadcast service for the live broadcast receiving terminal and the live broadcast initiating terminal. For example, the anchor may provide a live stream online in real time to the viewer through the live initiator and transmit the live stream to the server, and the live receiver may pull the live stream from the server for online viewing or playback.
In some implementations, the live receiver and the live initiator may be used interchangeably. For example, a anchor of a live originator may use the live originator to provide live video services to viewers, or as viewers to view live video provided by other anchors. For another example, a viewer at a live receiver may also use the live receiver to watch live video provided by a concerned anchor, or serve as the anchor to provide live video services to other viewers.
In some embodiments, the live receiver and the live initiator may include, but are not limited to, a mobile device, a tablet computer, a laptop computer, or any combination of two or more thereof. In some embodiments, the mobile device may include, but is not limited to, a wearable device, a smart mobile device, an augmented reality device, and the like, or any combination thereof. In some embodiments, the smart mobile device may include, but is not limited to, a smartphone, a Personal Digital Assistant (PDA), a gaming device, a navigation device, or a point of sale (POS) device, or the like, or any combination thereof.
In addition, in some possible implementations, there may be zero, one, or more live receivers and live initiators, only one of which is shown in fig. 1, accessing the server. The live broadcast receiving end and the live broadcast initiating end can be provided with internet products for providing internet live broadcast services, for example, the internet products can be application programs APP, Web webpages, applets and the like used in a computer or a smart phone and related to the internet live broadcast services.
In some embodiments, the server may be a single physical server or a server group consisting of a plurality of physical servers for performing different data processing functions. The set of servers can be centralized or distributed (e.g., the servers can be a distributed system). In some possible embodiments, such as where the server employs a single physical server, the physical server may be assigned different logical server components based on different live service functions.
It will be appreciated that the live system shown in fig. 1 is only one possible example, and that in other possible embodiments of the present application, the live system may also include only some of the components shown in fig. 1 or may also include other components.
In a live broadcast scene shown in fig. 1, for example, in the process of performing video live broadcast, a main broadcast on the live broadcast initiating end side may select to add some rendering special effects in a live broadcast picture in combination with some live broadcast requirements, so as to enrich the picture content during live broadcast and improve the viewing experience of a viewer.
For example, in some rendering schemes, a live broadcast initiating terminal may respond to a rendering request of a anchor broadcast, render a picture content of a live broadcast video frame, send the rendered live broadcast video frame to a server, and pull the rendered live broadcast video frame from the server by a live broadcast receiving terminal and play the live broadcast video frame, so that a viewer at the live broadcast receiving terminal can view the rendered live broadcast picture.
However, in the above-mentioned scheme in which the live broadcast initiator renders the screen content of the live broadcast video frame, rendering objects of some rendering schemes are the entire screen content of the live broadcast video frame, and cannot render specific objects in the live broadcast video frame, which results in poor rendering flexibility.
Based on this, in order to improve at least some of the defects in the rendering scheme, one possible implementation manner provided by the present application is: responding to a received video rendering request, and acquiring an object to be rendered corresponding to the video rendering request in a video frame to be rendered; then, rendering the object to be rendered by using the obtained video rendering parameters to obtain a target rendering result; fusing the target rendering result with the video frame to be rendered to obtain a live video frame; therefore, only the designated object in the video frame can be rendered, the whole video frame does not need to be rendered, and the flexibility in the rendering operation is improved.
Referring to fig. 2, fig. 2 shows a schematic block diagram of an electronic device 100 provided in the present application, and in some embodiments, the electronic device 100 may serve as a live broadcast initiator in fig. 1, and may also serve as a server in fig. 1.
Additionally, in some embodiments, electronic device 100 may include memory 101, processor 102, and communication interface 103, with memory 101, processor 102, and communication interface 103 being electrically connected to one another, directly or indirectly, to enable the transfer or interaction of data. For example, the components may be electrically connected to each other via one or more communication buses or signal lines.
The memory 101 may be configured to store software programs and modules, such as program instructions/modules corresponding to the live broadcast rendering apparatus provided in the present application, and the processor 102 executes the software programs and modules stored in the memory 101 to execute various functional applications and data processing, thereby executing the steps of the live broadcast rendering method provided in the present application. The communication interface 103 may be used for communicating signaling or data with other node devices.
The Memory 101 may be, but is not limited to, a Random Access Memory (RAM), a Read Only Memory (ROM), a Programmable Read-Only Memory (PROM), an Erasable Read-Only Memory (EPROM), an electrically Erasable Programmable Read-Only Memory (EEPROM), and the like.

It will be appreciated that the configuration shown in fig. 2 is merely illustrative and that electronic device 100 may include more or fewer components than shown in fig. 2 or may have a different configuration than shown in fig. 2. The components shown in fig. 2 may be implemented in hardware, software, or a combination thereof.
The electronic device 100 shown in fig. 2 is taken as an exemplary execution subject, and a live rendering method provided by the present application is exemplarily described below; it is understood that, in some embodiments, the electronic device 100 may serve as the live broadcast initiating terminal in fig. 1, and execute the live broadcast rendering method provided by the present application by receiving rendering parameters input by the anchor broadcast on the live broadcast initiating terminal side; of course, in some other embodiments, the electronic device 100 may also serve as the server in fig. 1, and execute the live rendering method provided by the present application by receiving the rendering parameter sent by the live initiator.
Referring to fig. 3, fig. 3 shows an exemplary flowchart of a live rendering method provided in the present application, and in some embodiments, the live rendering method may include the following steps:
And step 203, rendering the object to be rendered by using the obtained video rendering parameters to obtain a target rendering result.
And step 205, fusing the target rendering result with the video frame to be rendered to obtain a live video frame.
In some embodiments, taking the electronic device as the live broadcast initiating terminal in fig. 1 as an example, the display screen of the live broadcast initiating terminal may provide a rendering operation interface, and the rendering operation interface may configure a plurality of rendering operation options, such as configuring a rendered object, a rendered effect, and a rendered parameter, and so on; in the process of carrying out video live broadcast by using the live broadcast initiating terminal, the anchor can generate a video rendering request aiming at a specified rendering object (such as a character object in a live broadcast picture) by operating a rendering operation interface of the live broadcast initiating terminal, and configure corresponding video rendering parameters such as rendering effect, rendering duration, rendering position and the like.
Correspondingly, when a video rendering request input by a main broadcast is received in the process of video live broadcast, the live broadcast initiating end can respond to the video rendering request and take a video frame in a live broadcast code stream generated in the process of video live broadcast as a video frame to be rendered so as to obtain an object to be rendered corresponding to the video rendering request in the video frame to be rendered.
For example, assuming that a video rendering request input by the anchor is to render a character object in a video frame, the live broadcast initiator may identify the character object included in the video frame by using a scheme such as image recognition, so as to use the character object as an object to be rendered; or, assuming that the video rendering request input by the anchor is to render the background area in the video frame, the live broadcast initiating end may identify the background area in the video frame and use the identified background area as the object to be rendered.
In some embodiments, in the process of executing step 201, the live broadcast initiating end may perform image segmentation on the object to be rendered in the video frame to be rendered by using a scheme such as image segmentation, so as to obtain the object to be rendered and a remaining image area; in other possible embodiments of the present application, the live broadcast initiating end may also not perform image segmentation on the video frame to be rendered, but adopt an image extraction scheme to extract the target object to be rendered from the video frame to be rendered, and retain the complete video frame to be rendered.
Next, for the object to be rendered obtained by the live broadcast initiating terminal, the live broadcast initiating terminal may render the object to be rendered based on, for example, the video rendering parameter received by the anchor broadcast, so as to obtain a target rendering result, where the target rendering result is a rendering result corresponding to the object to be rendered, the rendering result being generated by the live broadcast initiating terminal in response to the video rendering request; in some embodiments, the video rendering parameters received by the live broadcast initiating end may be used to indicate operation contents for rendering the object to be rendered, such as a configured number of special effects, a special effect speed, a special effect size, a special effect offset, and the like.
Then, based on the target rendering result obtained by the live broadcast initiating terminal, the live broadcast initiating terminal may fuse the target rendering result with the video frame to be rendered, so as to obtain the live broadcast video frame which is rendered only for the object to be rendered as shown in fig. 4.
In some embodiments, in the process of executing step 205, the live broadcast initiating end may fuse the obtained target rendering result with the remaining image area after the object to be rendered is segmented, or may fuse the obtained target rendering result with the stored complete video frame to be rendered, which is not limited in this application.
Therefore, based on the scheme provided by the application, the received video rendering request is responded, and the object to be rendered corresponding to the video rendering request in the video frame to be rendered is obtained; then, rendering the object to be rendered by using the obtained video rendering parameters to obtain a target rendering result; fusing the target rendering result with the video frame to be rendered to obtain a live video frame; therefore, only the designated object in the video frame can be rendered, the whole video frame does not need to be rendered, and the flexibility in the rendering operation is improved.
It is understood that, in some possible scenarios, based on the difference of the content of the anchor live broadcast, the anchor may set a different number of rendering effects for the object to be rendered, for example, only one rendering effect may be set, or a plurality of rendering effects may be set.
For example, in the above scenario in which the live broadcast initiator in fig. 1 is used as the electronic device for executing the live broadcast rendering method of the present application, the live broadcast initiator may directly receive the video rendering parameters input by the anchor to execute the live broadcast rendering method of the present application.
For example, in a scenario in which the server in fig. 1 is used as an electronic device for executing the live rendering method of the present application, since the server needs to forward the video rendering parameters input by the anchor through the live initiator, in order to increase the generality of video rendering parameter acquisition, the live initiator may store the received video rendering parameters in a preset configuration file template after receiving the video rendering parameters input by the anchor, so as to generate a parameter configuration file.
Thus, when the live broadcast sending end in fig. 1 serves as an execution subject of the live broadcast rendering method provided by the present application, the live broadcast sending end may parse the parameter configuration file before executing step 203 to obtain a video rendering parameter for the object to be rendered; in this way, the live broadcast initiator performs step 203 based on the video rendering parameters obtained through parsing.
When the server in fig. 1 is used as an execution subject of the live rendering method provided by the present application, the live broadcast sending end may send a parameter configuration file to the server after generating the parameter configuration file; before executing step 203, the server may parse the parameter configuration file sent by the live broadcast initiating end to obtain the video rendering parameter for the object to be rendered, thereby executing step 203.
In some possible scenes, a rendering effect library may be preset at a live broadcast initiating end, and a plurality of function implementation modules of rendering effects may be stored in the rendering effect library in advance, for example, a plurality of function implementation modules of rendering effects such as "random shaking", "multi-ghost split", "channel split", "particle special effect" may be stored in the preset rendering effect library; the live broadcast initiating terminal can call and operate the function implementation module corresponding to each rendering effect respectively so as to implement various rendering effects.
In some embodiments, the anchor may configure at least one rendering effect based on some personalized selections in configuring the video rendering parameters.
Based on this, in order to improve that the live broadcast initiating end can meet different rendering requirements when rendering an object to be rendered, on the basis of fig. 3, please refer to fig. 5, fig. 5 shows an exemplary flowchart of the sub-step of step 203 in fig. 3, as a possible implementation, step 203 may include the following sub-steps:
step 203-1, configuring a rendering effect object set corresponding to the video rendering parameter from a preset rendering effect library.
And 203-3, rendering the object to be rendered based on the rendering effect object set to obtain a target rendering result.
In some embodiments, during the process of executing step 203, the live broadcast initiating end may first analyze the video rendering parameter, and configure a rendering effect object set corresponding to the video rendering parameter from a preset rendering effect library based on the video rendering parameter; for example, at least one rendering effect corresponding to the video rendering parameter is added to a pre-constructed queue, so as to obtain a rendering effect object set corresponding to the video rendering request, where the rendering effect object set includes at least one rendering effect.
Next, the live broadcast initiating end may render the object to be rendered based on the rendering effect object set; for example, the live broadcast initiating end may invoke a rendering engine shader to render each rendering effect in the set of rendering effect objects to the object to be rendered based on the set of rendering effect objects, so as to obtain a target rendering result.
It can be understood that, since the set of rendering effect objects includes at least one rendering effect, that is: the number of rendering effects included in the set of rendering effect objects is greater than or equal to one; then in some possible scenarios, when the set of rendering effect objects includes only one rendering effect, the live video frame may display only one rendering effect; in some other scenarios, when the set of rendering effects includes multiple rendering effects, the live video frame may display multiple rendering effects including "random shake", "multi-shadow split", and the like, as shown in fig. 4.
It should be noted that, in some possible scenarios, in order to improve the universality of the anchor in different rendering requirements, only the function implementation module of the rendering effect may be stored in the preset rendering effect library, and implementation parameters of the rendering effect, such as the rendering size, the rendering position, the rendering speed, and the like, are not stored; rendering parameters for different rendering effects may be input by the anchor together in the process of inputting the video rendering request.
Thus, in some embodiments, the video rendering parameters acquired by the live broadcast initiating terminal may include video rendering contents and display parameters corresponding to each video rendering content; for example, the video rendering content may indicate a corresponding rendering effect, and the display parameter may be used to indicate an implementation parameter of the corresponding rendering effect, such as a rendering size, a rendering position, a rendering speed, and the like.
Based on this, in some embodiments, during the process of executing step 203-1, based on the video rendering content in the obtained video rendering parameters, the live broadcast initiating end may determine all rendering effect objects corresponding to the video rendering content from a preset rendering effect library to obtain an initial rendering effect set; namely: the live broadcast initiator may first add the rendering effect template indicated in the video rendering parameters to the initial rendering effect set.
Next, the live broadcast initiating end may configure, based on the display parameter corresponding to each video rendering content included in the video rendering parameters, the corresponding display parameter for all rendering effect objects in the initial rendering effect set, so as to obtain a rendering effect object set.
For example, it is assumed that the initial rendering effect set includes a rendering effect of "random shaking", and the display parameters corresponding to the "random shaking" included in the video rendering parameters are "number: 0.07, speed: 0.8', the live broadcast initiating end can fill the display parameter quantity in the function implementation module corresponding to the random shaking: 0.07, speed: 0.8 ", so that the live initiator, in performing step 203-3, can determine the content based on the display parameters" number: 0.07, speed: 0.8 "achieve the rendering effect of" random shaking ".
In addition, it can be understood that the implementation manner provided by the present application is an example that the live broadcast initiating terminal performs rendering on one object to be rendered, in some possible scenarios of the present application, in combination with personalized configuration of the anchor, there may also be a plurality of objects to be rendered, and the video rendering parameters obtained by the live broadcast initiating terminal may include video rendering content corresponding to each object to be rendered.
For example, as shown in fig. 4, the anchor may configure some rendering effects not only for the character object in fig. 4, but also for the background area in fig. 4; alternatively, in some other possible scenarios in the present application, the anchor may also configure some rendering effects for some decorative pendants of the video frame.
For this reason, in a scene where a plurality of objects to be rendered exist, for example, the live broadcast initiator may perform layered rendering for different objects to be rendered.
For example, when there are multiple objects to be rendered, the live broadcast initiating terminal obtains the rendering effects corresponding to all video rendering contents from the preset rendering effect library to obtain an initial rendering effect object set during the process of executing step 203-1.
For example, assuming that the plurality of objects to be rendered include an object a and an object B, the rendering effect corresponding to the object a includes effect 1 and effect 2, and the rendering effect included in the object B includes effect 3, effect 4 and effect 5, the initial rendering effect object set may be expressed as { effect 1; effect 2; effect 3; effect 4; effect 5 }.
Next, in order to distinguish the objects to be rendered for which different rendering effects respectively aim at, the live broadcast initiating end may add a sentry identification pair corresponding to each object to be rendered in the initial rendering effect object set to obtain a rendering effect object set.
In some embodiments, each sentry identification pair may include a start sentry identification that may be used to indicate a start rendering effect of the corresponding object to be rendered and a stop sentry identification that may be used to indicate a stop rendering effect of the corresponding object to be rendered.
For example, referring to the foregoing example, after the live broadcast initiating end adds the sentry identifier pair corresponding to each of the object a and the object B in the initial rendering effect object set, the obtained rendering effect object set may be represented as: { initial a effect 1; effect 2; ending A and starting B effect 3; effect 4; effect 5; combining B }; wherein the set of rendering effect objects represents: effects 1 and 2 are used to render object a, and effects 3, 4, and 5 are used to render object B.
In this way, in the process of executing step 203-3, the live broadcast initiating terminal may render each corresponding object to be rendered based on all the sentry mark pairs in the rendering effect object set, so as to obtain a target rendering result.
For example, referring to the rendering effect object set { start a effect 1; effect 2; ending A and starting B effect 3; effect 4; effect 5; in combination with B }, when the live broadcast initiating terminal traverses to the "start a" in the process of traversing the rendering effect object set, the live broadcast initiating terminal can render the object a in the video frame based on the subsequently obtained effect 1 and effect 2 until traversing to the "end a", and complete rendering for the object a in the video frame; then, when the live broadcast initiating end traverses to the 'start B', the live broadcast initiating end can render the object B in the video frame based on the subsequently acquired effect 3, effect 4 and effect 5 until traversing to the 'end B', and rendering aiming at the object B in the video frame is completed; in this way, by performing the above-mentioned rendering operation on each video frame in the video bitstream, a cyclic rendering for the video bitstream is achieved.
In addition, in some possible scenes, with the improvement of live video quality and the like, the data volume of a video frame is generally large, and a live broadcast initiating end needs to consume certain processing resources and processing time in the process of rendering an object to be rendered, which is acquired from the video frame.
Based on this, in order to improve the speed of the live broadcast initiating terminal when rendering the object to be rendered, in other possible scenes, the anchor can also input a scaling ratio when inputting the video rendering parameters, so that the live broadcast initiating terminal can perform certain scaling on the object to be rendered when rendering the object to be rendered, and processing resources and processing time consumed when the live broadcast initiating terminal renders the object to be rendered are reduced.
In contrast, as another possible implementation manner, in the process of executing step 203, the live broadcast initiating end may further perform reduction processing on the object to be rendered according to the scaling in the video rendering parameter based on the scaling in the video rendering parameter, so as to reduce the data amount of the object to be rendered.
And then, the live broadcast initiating end can render the reduced object to be rendered according to the display parameters in the video rendering parameters to obtain an initial rendering result.
Then, the live broadcast initiating end may perform amplification processing on the initial rendering result according to a scaling ratio, that is: and reducing the reduced rendering object to the size before reduction to obtain a target rendering result.
