Fig. 9 is a schematic view illustrating a plurality of display areas in a bullet screen area in a bullet screen display method according to an embodiment of the present disclosure. As shown in fig. 9, the bullet screen area 31 may be divided into a plurality of display areas 32. In the example shown in fig. 9, the bullet screen area 31 is divided into 5 display areas 32. One skilled in the art will appreciate that the number of display areas may be greater or fewer and that embodiments of the present disclosure do not limit the location of the display areas.
It should be noted that the shape of the display area is not limited in the embodiments of the present disclosure. The shape of the display area can be any shape such as rectangle, circle, ellipse or triangle.
In one possible implementation, the position of the presentation area may be determined by the geometric center of the presentation area. In this implementation, the determining of the first display area corresponding to the first bullet screen may be determining a geometric center of the first display area corresponding to the first bullet screen. The size of the display area may be determined according to the font size and the number of words of the display area.
In a possible implementation manner, determining a first display area corresponding to the first bullet screen includes: and determining a display area which has the highest priority and is not displayed with the bullet screen in the bullet screen area as a first display area corresponding to the first bullet screen. Wherein, the display area without displaying the bullet screen represents the display area without the bullet screen at present. For example, in the example shown in fig. 9, the priority of the presentation area in the middle is higher than the priority of the presentation areas on both sides. For example, only the display area E and the display area F in all the display areas are display areas not displaying the bullet screens, and then the display area E may be used as the first display area corresponding to the first bullet screen.
In one possible implementation manner, the font size of the bullet screen segment of the first bullet screen is determined according to the user parameter of the publishing user of the first bullet screen.
In this implementation, the larger the user parameter of the publishing user of the first barrage is, the larger the font of the barrage fragment of the first barrage is. The font size of the bullet screen is larger than or equal to the equipment reference font size and smaller than the maximum preset font size.
As an example of this implementation, the user parameters of the publishing user are determined according to at least one of: publishing the online time of the user; posting a member level of the user; and publishing the activity of the user.
In this example, the longer the online duration of the publishing user, the larger the user parameters of the publishing user; the higher the member level of the publishing user is, the larger the user parameter of the publishing user is; the higher the liveness of the publishing user, the larger the user parameters of the publishing user.
In this example, the liveness of the publishing user may be determined according to at least one of: the method comprises the steps of publishing the number of the barracks published by a user, publishing the number of comments published by the user, publishing the praise times of the user, publishing the forwarding times of the user, publishing the collection times of the user and subscribing times of the user.
For example, the more the number of the bullet screens published by the publishing user is, the higher the liveness of the publishing user is; the more the number of the comments issued by the issuing user is, the higher the activeness of the issuing user is; the more the praise times of the publishing user are, the higher the activity of the publishing user is; the more forwarding times of the publishing user, the higher the activity of the publishing user; the more the collection times of the publishing user are, the higher the activity of the publishing user is; the more subscriptions a publishing user has, the higher the liveness of the publishing user.
In one possible implementation, the radius of curvature of the rotational trajectory is determined according to user parameters of a posting user of the first bullet screen.
In this implementation, the larger the user parameter of the posting user of the first bullet screen, the larger the radius of curvature of the rotation trajectory.
In a possible implementation manner, before determining the first display area corresponding to the first bullet screen, the method further includes: and determining the bullet screen with the highest priority in the bullet screens to be displayed as a first bullet screen.
As an example of this implementation, the priority of the bullet screen is determined according to at least one of: the time difference between the delivery time of the bullet screen and the time of the video frame to be played; publishing user parameters of the user; mass fraction of bullet screen.
In this example, the delivery time of a bullet screen may represent the point in time when the delivery user of the bullet screen views the video for which the bullet screen is being delivered. The time of a video frame may represent a point in time of the video frame in the video to which the video frame belongs. The user who posts the barrage can show the user who posts this barrage.
In this example, the smaller the time difference between the publication time of the bullet screen and the time of the video frame to be played, the higher the priority of the bullet screen; the larger the user parameter of the user who issues the bullet screen is, the higher the priority of the bullet screen is; the higher the mass fraction of the bullet screen, the higher the priority of the bullet screen.
In this example, a pre-trained first neural network may be employed to determine a quality score for the bullet screen. The first neural network can be trained according to a large number of bullet screens and the number of praise of the bullet screens. For example, before training the first neural network, the quality score of the bullet screen can be labeled according to the praise number of the bullet screen. When the first neural network is trained, the bullet screen can be used as the input of the first neural network, and the mass fraction of the bullet screen can be used as the output of the first neural network, so that the first neural network is trained and optimized.
In the embodiment of the disclosure, a full-duplex communication channel may be established between the client and the server through a Socket or a WebSocket protocol, and the server may push a barrage of a video to a client (e.g., a browser) playing the video through the full-duplex communication channel.
In one possible implementation, the client may cache the bullet screen to be displayed.
In a possible implementation manner, the client may request the interface to obtain the bullet screen to be displayed at a preset time interval. For example, the preset time interval is 2 seconds.
In one possible implementation, the method further includes: and adjusting the position of the first display area according to the position of the person in the video frame being played. In this implementation, the first presentation area may be controlled to move to a position that does not occlude the person. For example, the first display area may be controlled to move in an arcuate trajectory to a position that does not occlude the person. The first display area is controlled to move to the position where the person is not shielded, so that the user can watch the video content more conveniently.
In one possible implementation, the method further includes: and if the user parameter of the publishing user of the first bullet screen is greater than the third threshold value, displaying the first mark in the first display area. Wherein, the first mark is used for highlighting the first bullet screen.
In another possible implementation manner, the method further includes: and if the mass fraction of the first bullet screen is greater than the fourth threshold value, displaying a first mark in the first display area.
In another possible implementation manner, if the user parameter of the publishing user of the first barrage is greater than a third threshold and the mass fraction of the first barrage is greater than a fourth threshold, the first mark is displayed in the first display area.
In one possible implementation, different bullet screens in a bullet screen zone may be presented in different ways.
