The network live broadcast is a new life and entertainment mode and is popular with the vast netizens. For live broadcast, the presentation of live broadcast content is very important, excellent live broadcast content needs to have a sense of bringing in, and due to the objective condition of live broadcast, the anchor and audiences are physically isolated, so that on one hand, the anchor cannot feel the positive feedback of the audiences, and the subsequent live broadcast content is influenced. On the other hand, the audience cannot directly feel the reaction of other audiences to the live content, and is often difficult to be driven by the live content.
In contrast, the live broadcast service provider provides an atmosphere special effect service for assisting the anchor in enhancing the sense of bringing in live broadcast content. For example, when the anchor intentionally stops embarrassing, the player can play the crow sound to enhance the atmosphere. For another example, when the anchor refers to a laugh point, the sound enhancement atmosphere of a laugh with haha and haha can be played.
Obviously, the manner of atmosphere presentation described above is very single, and the audience can only sense the atmosphere in hearing, which significantly compromises the effect of the atmosphere.
In order to improve the above problem, embodiments of the present invention provide an atmosphere special effect generation method, an apparatus, an electronic device, and a storage medium.
The atmosphere special effect generation method and device can be applied to the live broadcast scene shown in fig. 1. As shown in fig. 1, a live client (also called a main broadcast) collects live image frames to generate live video data, and sends the live video data to a video server in the form of a video stream. And after the video server carries out relevant processing on the live video data, the live video data are sent to the corresponding audience client. The viewer client may be a client used by a viewer entering a live room created by a live client.
It should be noted that the live client and the viewer client are essentially clients that obtain services from the video server, and the difference is only in roles that are assumed in the live activities. Each client can switch between the live client and the viewer client according to the user's selection. For example, if a user a uses a client a to perform live broadcasting, the client a is a live broadcasting client, and a client B used by a user B who enters a live broadcasting room created by the user a is an audience client. After the user A downloads, when the client A enters a live broadcast room created by the user B, the client B used by the user B who is carrying out live broadcast is a live broadcast client, and the client A is an audience client.
The atmosphere special effect generation method and device provided by the embodiment of the invention can be applied to the live broadcast client in the figure 1.

It is to be understood that the server is not limited to a physical server, and may also be a virtual machine on the physical server, a virtual machine built on a cloud platform, or the like, which can provide the same function as the server or the virtual machine. A large amount of atmosphere special-effect resources are stored in the live broadcast server, so that the client can download and use the atmosphere special-effect resources conveniently. The atmosphere special effect resource can be one of or a combination of special effect music, animation special effect data and special effect filter parameters.
The client may be an application installed in the electronic device. After the client starts to operate, the hardware resource of the electronic equipment can be called to perform data interaction with the live broadcast server, so that services provided by the live broadcast server are obtained, such as starting live broadcast, entering a live broadcast room to watch live broadcast, downloading atmosphere special effect resources and the like. The electronic device may be an intelligent device with image capturing and displaying functions, for example, the electronic device may include a mobile phone, a smart home device, a wearable device, an intelligent mobile device, a virtual reality device, an augmented reality device, or the like, or may be a tablet computer, a laptop computer, or a built-in device in a motor vehicle, or the like.

First embodiment
Referring to fig. 3, fig. 3 illustrates an atmosphere special effect generation method according to an embodiment of the present invention. As shown in fig. 3, the atmosphere special effect generation method may include the following steps:
and S101, loading target special effect resources corresponding to the clicking operation according to the sensed clicking operation.
The target special-effect resource is an atmosphere special-effect resource which can be obtained from a live broadcast server. Therefore, the target special effect resource can also comprise special effect music, animation special effect data and special effect filter parameters.
In some embodiments, the animated special effects data may be a static image (e.g., a decal). In other embodiments, the animation special effect data may further include multiple frames of special effect animation frames, and the multiple frames of special effect animation frames may be rapidly switched in sequence to present an animation state.
In some embodiments, the above-mentioned special effect filter parameter may be a parameter for adjusting an image screen. For example, the special effect filter parameter may be a picture adjustment parameter for face thinning, a picture adjustment parameter for beauty, a picture adjustment parameter for large eyes, an adjustment parameter for switching a picture to black and white, an adjustment parameter for changing a picture style into a cartoon wind, and the like.
The above-described clicking operation is an operation that the electronic apparatus 100 senses as being triggered by the user. The electronic device 100 may present, to a user, a to-be-selected special effect resource (the to-be-selected special effect resource includes an atmosphere special effect resource downloaded from a live broadcast server, an atmosphere special effect resource downloadable from a live broadcast server, and an atmosphere special effect resource customized by a host), and thus, a target special effect resource may be determined from the presented to-be-selected special effect resource according to the sensed click operation.
In order to explain the obtaining manner of the customized atmosphere special effect resource, the customized atmosphere special effect resource is referred to as a customized atmosphere special effect resource, and the system special effect resource is referred to as an atmosphere special effect resource which can be downloaded from a live broadcast server.
In some embodiments, the customized special effect resource may be generated by a user by changing at least one special effect in the system special effect resource, for example, the user may upload customized music to replace special effect music in the system special effect resource, so as to combine the customized special effect resource. Of course, the special effect animation and the special effect filter parameters can be replaced by the user-defined contents.
In some embodiments, the customized special effect resource may also be a user uploading customized music and customized animation frames and selecting available filter special effect parameters from filter special effect parameters available in a live broadcast service. And combining the self-defined music, the self-defined animation frame and the available filter special effect parameters to obtain the self-defined special effect resource.
In addition, in the process of watching live broadcast, if a user likes the customized special effect resource used in a certain live broadcast room, the customized special effect resource can be obtained through a specific button of a live broadcast room interface, and sharing of the customized special effect resource is achieved.
The mode of displaying the atmosphere special effect resource to be selected can be displayed in a name shortcut mode. The name shortcut key can be a touch key carrying the name of the atmosphere special effect resource to be selected.
Illustratively, as shown in fig. 4, a plurality of special effect resources to be selected are shown in a display interface of the electronic device 100 operating the client, where a touch key carrying a name "cheering by multiple persons" corresponds to the special effect of cheering by multiple persons, a touch key carrying a name "highlight moment" corresponds to the special effect of atmosphere at highlight moment, and a touch key carrying a name "cool and cool" corresponds to the special effect of atmosphere at cool. When the touch operation of the user is sensed to point to the touch key carrying the name 'cheering more than one person', the special effect resource to be selected (cheering more than one person atmosphere special effect resource) can be determined as the target special effect resource.
In some embodiments, if the target special effect resource is already downloaded into the electronic device 100, the loading of the target special effect resource may be to obtain corresponding special effect music, animation special effect data, and special effect filter parameters from the inside of the electronic device 100.
In other embodiments, if the target special effect resource is not downloaded to the electronic device 100, the loading of the target special effect resource may be requesting to obtain corresponding special effect music, animation special effect data, and special effect filter parameters from a live broadcast server.
And step S102, processing the collected actual image frame by using the special effect filter parameters while starting to play the special effect music until the special effect music stops playing.
The actual image frame is the raw image data collected by the electronic device 100. In some embodiments, the actual image frames may be processed to obtain live images, and the live images may be sent to the live server in a video stream manner so as to be forwarded by the live server to the viewer client. In other embodiments, the actual image frames may not be processed, and the actual image frames are used as live images and sent to the live server in a video streaming manner, so as to be forwarded by the live server to the viewer client.
It will be appreciated that whether or not the actual image frames are processed is primarily a function of the live effect selected by the user.
In some embodiments, each frame of actual image frames collected during the playing of the special effect music is processed by using the special effect filter parameters in the target special effect resource. For example, the parameters of the special effect filter in the target special effect resource are parameters for indicating face thinning, so that each frame of actual image frame acquired during the playing of special effect music is subjected to face detection, and face thinning is performed when a face is detected.
And step S103, when the playing of the special effect music is started, the animation special effect data is superposed on the collected actual image frame until the playing of the special effect music is stopped.
In some embodiments, in the case where the animation special effect data includes one frame of special effect animation frame, the special effect animation frame is pasted in each of the captured actual image frames during the playing of the special effect music.
In other embodiments, when the animation special effect data includes multiple frames of special effect animation frames, a dynamic image is generated according to the multiple frames of special effect animation frames according to a preset animation sequence, and the dynamic image is superimposed on the acquired actual image frame.
Understandably, during the playing of the special effect music, the audio data of the special effect music and the processed live broadcast picture (i.e., the actual image frame processed by the filter and superimposed with the animation special effect data) are synchronously encoded and sent to the live broadcast server, so that the live broadcast server forwards the encoded audio data to the corresponding audience client for watching.
The synchronous presentation of the special effect music, the special effect filter and the animation special effect can be realized through the step S102 and the step S103.
In the foregoing embodiment, it is mentioned that the electronic device 100 may present the special effect resource to be selected by means of name shortcut. Although this method is simple and fast, it is difficult for a user who is not familiar with the special effect resource to be selected to quickly select a desired atmosphere special effect. To solve this problem, in some embodiments, the atmosphere special effect generation method further includes: and popping up an atmosphere preview frame under the condition that the atmosphere preview control is sensed to be triggered.
The effect example animations corresponding to the multiple to-be-selected special effect resources are displayed in the atmosphere preview frame, so that a user can determine the target special effect resource from the multiple to-be-selected special effect resources through clicking operation. For example, as shown in fig. 5, the atmosphere preview control is triggered, and the atmosphere preview frame pops up in the display interface of the electronic device 100.
The animation with the effect example is a short video obtained by processing a sample video by using special effect music, animation special effect data and special effect filter parameters in the special effect resource to be selected. The effect example animation described above may be generated in advance.
And after the atmosphere preview frame is popped up, automatically playing in a circulating way by using the effect example animation corresponding to each to-be-selected special effect resource so as to provide the user with the realization effect of referring to the atmosphere special effect. As shown in fig. 5, after the atmosphere preview frame is popped up, an effect example animation corresponding to the special effect of the cheering atmosphere of the plurality of persons, the special effect of the atmosphere at the highlight moment and the special effect of the cool atmosphere is displayed in the atmosphere preview frame.
It is mentioned in the above-mentioned step S102 and step S103 that the trigger point for the actual image frame using the special effect filter parameter and the animation special effect data is the start playing of the special effect music.
In some embodiments, after the user selects and finishes loading the target special effect resource, the playing of the special effect music can be started, so that the actual image frame is processed in a linkage manner.
In other embodiments, to avoid a pause caused by temporarily selecting an atmosphere special effect resource to live broadcast, after loading a target special effect resource corresponding to the click operation, as shown in fig. 6, the atmosphere special effect generation method further includes:
step S201, determining a trigger action from the effect example animation corresponding to the target special effect resource.
In some embodiments, if only one target special effect resource is selected, multiple selectable actions that occur may be recognized from the example animation, such as, but not limited to, a waving action, a heart-to-heart action, a blinking action, a waving action, and the like, as selectable actions. One of the selectable actions that occurred in the example animation is then randomly selected as the trigger action.
Of course, corresponding weight values can also be set for various actions in advance, and the higher the weight value is, the more preferable the weight value is. Then, the selectable action with the highest weight value is determined as the trigger action.
In some embodiments, if only a plurality of target special effect resources are selected, a plurality of selectable actions that appear may be identified from the effect example animations of the respective target special effect resources, and then an action that serves as a trigger action is selected from the selectable actions corresponding to each target special effect resource, and it is necessary to ensure that the trigger actions corresponding to different target special effect resources are different. For example, before the anchor broadcasts live, a target special effect resource a and a target special effect resource b to be used are selected in advance, a shaking motion and a panning motion occur in an effect example animation corresponding to the target special effect resource a, a panning motion and a waving motion occur in an effect example animation corresponding to the target special effect resource b, and a weight value of the panning motion is higher than that of the shaking motion and the waving motion. Therefore, after the trigger action corresponding to the target special effect resource a is set to be the heart action, the trigger action corresponding to the target special effect resource b can only be set to be the waving action, so that the anchor can easily and alternately use various pre-selected atmosphere characteristics in the live broadcast process, and the live broadcast content quality is improved.
That is, the trigger action corresponding to the target special effect resource is not fixed, and different actions occurring in the effect example animation can be determined as the trigger action according to the actual situation. For example, in the case that different atmosphere special effect resources are selected to be used, the finally determined trigger action may be different.
After the trigger action corresponding to the target special effect resource is selected, the trigger action can be prominently displayed in the effect example animation (for example, the playing speed is slowed down when the effect example animation is played to the trigger action, and text reminding is performed), so that a user can conveniently trigger playing of the corresponding special effect music by simulating the trigger action.
And step S202, performing trigger action check according to the collected actual image frame.
In some embodiments, action recognition may be performed on multiple frames of actual image frames in a video stream captured by a live client to determine whether the trigger action occurs in the video stream captured by the live client.
In step S203, if the trigger action is detected, the playing of the special music is started.
In some embodiments, when a trigger action is detected, special effect music in a target special effect resource corresponding to the trigger action is started, and then the actual image frames collected by the client are processed by using animation special effect data and special effect filter parameters in the corresponding target special effect resource in a linkage manner.
As shown in fig. 7, the trigger action determined from the effect example animation of the target special effect resource is a heading action, so that no special effect music is played and no actual image frame is processed before the heading action does not occur in the acquired actual image frame. Of course, once the action of pushing the ball occurs, the playing of special effect music is started, and the filter processing and the animation overlaying processing are carried out on the actual image frames in a linkage manner.
In some embodiments, in order to make a user better feel an implementation effect of a target special effect resource, the atmosphere special effect generating method further includes:
(1) and under the condition of receiving a use effect simulation instruction input by a user, acquiring a target object selected by the user in the actual image frame. The target object may be framed by the user in the actual image frame, for example, a person appearing in the actual image frame may be selected.
(2) And replacing the replaceable object in the effect example animation corresponding to the plurality of special effect resources to be selected with the target object to obtain the effect simulation animation and displaying the effect simulation animation in the atmosphere preview frame. The replaceable object may also be selected by the user in a box in the effect example animation, for example, a person appearing in the sample video corresponding to the effect example animation.
In order to execute the corresponding steps in the above embodiments and various possible manners, an implementation manner of the atmosphere special effect generation apparatus 400 is given below, and optionally, the atmosphere special effect generation apparatus 400 may adopt the device structure of the electronic device 100 shown in fig. 2.
