A bullet screen prompting method provided by the embodiment of the present invention is described in detail below with reference to fig. 1.
As shown in fig. 1, a bullet screen prompting method provided in an embodiment of the present invention may include:
s101, when a user operates a bullet screen input box in a playing interface of a multimedia file, determining currently played multimedia data of the multimedia file as target data;
it can be understood that when the user has a requirement for publishing the bullet screen, the user can realize publication of the bullet screen by operating the bullet screen input box. The bullet screen input box can be arranged at any position of the playing interface, or a user can click the input box display button to display the bullet screen input box in the playing interface. Correspondingly, there may be a plurality of ways for the user to operate the bullet screen input box, for example, when the bullet screen input box is set in the play interface, the ways for the user to operate the bullet screen input box may include: clicking the bullet screen input box; for example, when the bullet screen input box needs to be displayed by clicking an input box display button, the manner of the user operating the bullet screen input box may include: and clicking an input frame display button in the playing interface to display the bullet screen input frame in the playing interface, and further clicking the bullet screen input frame. In addition, when the bullet screen prompting method is applied to the server, the server detects that the user operates a bullet screen input box in a playing interface of the multimedia file when a bullet screen prompting word generation request sent by the multimedia client is received.
Moreover, the multimedia file may be composed of multimedia data with different data lengths, and the bullet screen that the user needs to publish may have a large association with the currently played multimedia data. Therefore, in order to improve the matching degree between the generated bullet screen prompt words and the user requirements, when the user operates a bullet screen input box located in a playing interface of the multimedia file, the currently played multimedia data of the multimedia file can be determined as target data. Moreover, for a video file, the currently played multimedia data of the multimedia file may be a currently played video frame of the video file; for an audio file, the currently played multimedia data of the multimedia file may be a currently played audio frame, i.e., an audio segment, of the audio file.
For example, in one implementation, determining currently playing multimedia data of the multimedia file as the target data may include: determining the played time length of the multimedia file, and determining the currently played multimedia data of the multimedia file as target data according to the played time length and the file time length of the multimedia file; or, identifying a current playing time point, and determining the multimedia data of the current playing time point as the currently played multimedia data of the multimedia file.
It can be understood that, in the playing process of the multimedia file, each playing time point has corresponding multimedia data, and then, according to the played time length of the multimedia file and the file time length of the multimedia file, the current playing time point of the multimedia file can be determined, so that the multimedia data corresponding to the current playing time point can be determined.
In addition, in order to improve the user experience, whether to execute the barrage prompting process can be determined according to the requirements of the user. In an implementation manner, the mobile terminal may provide a function switch for a user whether to start the barrage prompting function, and the function switch may be set on a setting interface of the mobile terminal or a playing interface of the multimedia file. For the condition that the function switch is arranged on the setting interface, a user can start the function in the setting interface, so that the mobile terminal can trigger and execute S101 when the multimedia file starts to play; for the case that the function switch is set in the playing interface, the user may start the function in the playing interface, so that the mobile terminal may trigger to execute S101 when the multimedia data starts to be played.
In another implementation manner, the mobile terminal may implement the barrage prompting process by requesting user authorization. For example: the mobile terminal outputs prompt information for guiding the user to authorize, and when the user selects authorization, the mobile terminal can execute the barrage prompting process, and when the user does not select authorization, the mobile terminal does not execute the barrage prompting process. The output timing of the prompt message may include, but is not limited to: the user requests to play the multimedia file during the playing process of the multimedia file.

wherein the reference information may include: a history bullet screen associated with the target data, and/or target multimedia data which contains the target data and belongs to a specified data length. For example, when the target data is video data, the target multimedia data of the specified length may be: a specified number of video frames; when the target data is audio data, the target multimedia data of the specified length may be: audio data of a specified audio length.
Considering that reference information of target data may be various, specific implementation manners for generating the first type of bullet screen candidate words for the target data according to the reference information of the target data may be various. Illustratively, in one implementation, when the reference information includes: when the target multimedia data is generated, according to the reference information of the target data, the generating of the first type of bullet screen candidate words for the target data may include: and identifying object information and/or scene information contained in the target multimedia data as a first type of bullet screen candidate word aiming at the target data.
There may be various object information and/or scene information included in the target multimedia data, for example: and identifying object information and/or scene information contained in the target multimedia data through a preset neural network model.
In this case, the identifying object information and/or scene information included in the target multimedia data may include:
and inputting the target multimedia data into a pre-trained neural network model for identifying the object information and/or the scene information to obtain the object information and/or the scene information contained in the target multimedia data.

Illustratively, in another implementation, when the reference information includes: when the historical bullet screen is associated with the target data, generating a first type of bullet screen candidate word for the target data according to the reference information of the target data may include: and screening the bullet screens meeting the preset heat condition from the historical bullet screens associated with the target data to serve as first-class bullet screen candidate words for the target data.
Considering that different users may publish the same bullet screen for the same target data, when generating the first type bullet screen candidate words, the bullet screen meeting the predetermined heat condition may be filtered from the historical bullet screens associated with the target data as the first type bullet screen candidate words for the target data.
Optionally, in an implementation manner, any one of the following manners may be adopted to screen the bullet screens meeting the predetermined heat condition, including;
the method comprises the steps that in the first mode, the occurrence frequency of each bullet screen in historical bullet screens relevant to target data is determined; and taking the bullet screen with the occurrence frequency larger than a preset threshold value as the bullet screen meeting the preset heat condition.
The preset threshold may be determined according to needs and scenes, for example, the preset threshold may be 6.
In a second mode, sorting historical barrages associated with target data according to occurrence times; taking the bullet screens sequenced in the preset range as bullet screens meeting the preset heat condition
The preset range may be N in the top order, N may be determined according to the requirement and the scene, and for example, N may be 4.
The predetermined thermal condition may include various conditions, such as: the occurrence times reach a preset threshold value, and the occurrence times are sorted in a preset range, for example: sort first N, and so on.
In addition, when the reference information includes both a historical bullet screen associated with the target data and target multimedia data that includes the target data and belongs to a specified data length, generating a first type of bullet screen candidate word for the target data according to the reference information of the target data may include: identifying object information and/or scene information contained in the target multimedia data; screening the bullet screens meeting the preset heat condition from the historical bullet screens associated with the target data; and determining the identified object information and/or scene information and the screened bullet screens as first-class bullet screen candidate words aiming at the target data.
S103, outputting bullet screen prompt words aiming at the target data in the playing interface based on the first type bullet screen candidate words;
the bullet screen prompt words are contents selectable by the user and are displayed in the playing interface as input contents after being selected.
For example, in an implementation manner, outputting, in the play interface, a bullet screen cue word for the target data based on the first type of bullet screen candidate word may include: and taking the first type of bullet screen candidate words as bullet screen prompt words aiming at the target data, and outputting the bullet screen prompt words on the playing interface.
It can be understood that there may be a plurality of bullet screen cue words output, then, after the bullet screen cue words for the target data are output in the playing interface, the user may select one or more bullet screen cue words from the output bullet screen cue words for publication, where the manner in which the user selects the bullet screen cue words may include, but is not limited to: clicking the output bullet screen prompt words, and the like. For example, in one implementation, when the user selects from the bullet screen cue words by clicking, the selected bullet screen cue words may serve as input content, and a bullet screen display area of the playing interface is displayed, where the bullet screen display area may be located at any position of the playing interface, for example: top, intermediate, etc.
For example, in another implementation manner, when the user selects from the bullet screen cue words by clicking, the selected bullet screen cue words may be displayed in a bullet screen input box of the playing interface as input content, and when a publication instruction of the user is obtained, the content in the bullet screen input box is published.
In addition, in order to improve the user experience, whether to display the bullet screen in the bullet screen display area can be determined according to the user requirements. For example, the playing interface may provide a function switch for a user whether to turn on a bullet screen displayed in the bullet screen display area, and when the function switch is turned on, the bullet screen display area may display a historical bullet screen, a currently published bullet screen, and the like.
According to the scheme, when a user operates the bullet screen input box, the first type of bullet screen candidate words can be automatically generated according to the reference information of the target data, and bullet screen prompt words are output on the play interface based on the first type of bullet screen candidate words for selection of the user, so that the problem that the user needs to manually input the bullet screen, and the input process is not convenient enough is solved.
Optionally, in another embodiment of the present invention, before outputting the bullet screen cue word for the target data in the playing interface based on the first type of bullet screen candidate word, the method may further include:
and when detecting that the related key words are input into the bullet screen input box, generating second type bullet screen candidate words aiming at the target data by using the key words and the historical bullet screen associated with the target data.
It is understood that, after the user operates the bullet screen input box, the user may input a keyword in the bullet screen input box, where the keyword may be a part of the bullet screen conceived by the user. Then, for convenience of user input, a second type of bullet screen candidate word for the target data may be generated by using the keyword and the historical bullet screen associated with the target data when the related keyword is detected to be input in the bullet screen input box.
For example, in one implementation, generating a second type of bullet screen candidate word for the target data by using the keyword and a historical bullet screen associated with the target data may include: and determining the bullet screens matched with the keyword from the historical bullet screens associated with the target data as second-type bullet screen candidate words aiming at the target data.
Wherein, the implementation process of determining the bullet screen matched with the keyword is not specifically limited, for example: compare the keyword to a historical bullet screen associated with the target data, and so on. It is contemplated that one or more matching barrages may be determined from the historical barrages associated with the target data. Then, for example, when a plurality of matched bullet screens are determined, it is reasonable that all the determined bullet screens are used as second-type bullet screen candidate words for the target data, or the bullet screen with the largest occurrence frequency in the determined bullet screens is used as the second-type bullet screen candidate words for the target data.
As the generated bullet screen candidate words may include a first type of bullet screen candidate words and a second type of bullet screen candidate words, in an exemplary implementation manner, based on the first type of bullet screen candidate words, the outputting of the bullet screen cue words for the target data in the play interface includes:
