In some instances, methods, means, elements and circuits that are well known to those skilled in the art have not been described in detail so as not to obscure the present disclosure.
Fig. 1 shows a flowchart of a method of controlling a bullet screen speed according to an embodiment of the present disclosure. The method may be applied to a terminal device, and may also be applied to a server, which is not limited herein. The method can control the speed of the bullet screen displayed on the large-screen bullet screen on site, and can also control the speed of the bullet screen in the video played by the terminal device, which is not limited herein. As shown in fig. 1, the method includes step S11 and step S12.
In step S11, a first speed corresponding to the target bullet screen is determined.
In one possible implementation, determining the first speed corresponding to the target bullet screen may include: and determining a first speed corresponding to the target bullet screen according to the length of the target bullet screen, wherein the first speed is positively correlated with the length. In this implementation, the longer the length of the target bullet screen, the greater the first speed, and the shorter the length of the target bullet screen, the smaller the first speed.
As an example of this implementation, a first speed corresponding to the target bullet screen may be determined according to the first presentation time and the length of the target bullet screen. Wherein the first presentation time may be set by a user. For example, the first speed corresponding to the target bullet screen can be determined according to the ratio of the length of the target bullet screen to the first display time. For example, the product of the ratio and a first preset speed may be taken as the first speed.
In another possible implementation manner, determining the first speed corresponding to the target bullet screen may include: according to the length of the target bullet screen and one or two of the first bullet screen quantity and the second bullet screen quantity, a first speed corresponding to the target bullet screen is determined, wherein the first bullet screen quantity represents the bullet screen quantity being displayed, the second bullet screen quantity represents the bullet screen quantity beginning to be displayed at the same moment with the target bullet screen, the first speed is positively correlated with the length, the first speed is positively correlated with the first bullet screen quantity, and the first speed is positively correlated with the second bullet screen quantity. In this implementation, if the first bullet screen amount and/or the second bullet screen amount are/is larger, it may be indicated that more bullet screens are displayed on the screen.
As one example of this implementation, the amount of the bullet screen that starts to be presented at the 1 st to tth calculation times before the current calculation time may be determined as the first bullet screen amount. Each calculation time may be 1 second, and the current calculation time represents a calculation time at which the target bullet screen starts to be displayed. For example, T equals 8.
For example, the first bullet screen amount
Figure BDA0001528829860000061
Wherein, ctIndicating the amount of the bullet screen which starts to be displayed at the tth calculation time before the current calculation time.
As another example of this implementation, the first bullet screen amount may be an amount of bullet screens that are already being displayed and are not displayed at the time of starting to display the target bullet screen.

For example, the first speed V corresponding to the target bullet screen can be determined according to equation 11，
Figure BDA0001528829860000062
Wherein l represents the length of the target bullet screen, C1Indicates the first bullet screen amount, C2Indicates the second bullet screen amount, C0Indicating a preset value of the amount of the bullet screen, w1Denotes a first coefficient, w2Denotes a second coefficient, VlRepresenting a first predetermined speed, VCRepresenting a second preset speed.

According to the implementation mode, the display speed of the target bullet screen is improved when the bullet screen amount on the screen is large, and the display speed of the target bullet screen is reduced when the bullet screen amount on the screen is small, so that the phenomenon that a large number of bullet screens occupy too long time of the screen can be avoided, and the bullet screens still flash when the bullet screen amount on the screen is small can be avoided.
In step S12, the display speed of the target bullet screen is determined according to the first speed and the priority of the target bullet screen.
In one possible implementation, the display speed of the target bullet screen is inversely related to the priority of the target bullet screen. The higher the priority of the target bullet screen is, the slower the display speed of the target bullet screen is, and the lower the priority of the target bullet screen is, the faster the display speed of the target bullet screen is.
In the present embodiment, the display speed of the target bullet screen is positively correlated with the first speed.
In a possible implementation manner, the priority of the target bullet screen may be determined according to the user information of the sending user of the target bullet screen.
As an example of the implementation manner, if the sending user of the target bullet screen is determined to be an important user according to the user information of the sending user of the target bullet screen, the priority of the target bullet screen may be determined to be a first priority; if the sending user of the target bullet screen is determined to be a common user according to the user information of the sending user of the target bullet screen, the priority of the target bullet screen can be determined to be a second priority. Wherein the first priority is higher than the second priority. The important users may include a star user or a member user, etc., which are not limited herein.
As another example of the implementation manner, if the sending user of the target bullet screen is determined to be a star user according to the user information of the sending user of the target bullet screen, the priority of the target bullet screen may be determined to be a first priority; if the sending user of the target bullet screen is determined to be a member user according to the user information of the sending user of the target bullet screen, the priority of the target bullet screen can be determined to be a second priority; if the sending user of the target bullet screen is determined to be a common user according to the user information of the sending user of the target bullet screen, the priority of the target bullet screen can be determined to be the third priority. Wherein the first priority is higher than the second priority, which is higher than the third priority.
It should be noted that, although the manner of determining the priority of the target bullet screen according to the user information of the sending user of the target bullet screen is described above by way of example, those skilled in the art can understand that the present disclosure should not be limited thereto. The method for determining the priority of the target bullet screen according to the user information of the sending user of the target bullet screen can be flexibly set by a person skilled in the art according to the requirements of the actual application scene and/or personal preferences.
In another possible implementation manner, the priority of the target bullet screen may be determined according to the type of the target bullet screen. In this implementation, the segmentation processing may be performed on the target bullet screen, and the segmentation result may be analyzed to determine the type of the target bullet screen.
As an example of this implementation, if the type of the target barrage is a funny barrage, the priority of the target barrage may be determined to be a first priority; if the type of the target barrage is the non-fun barrage, the priority of the target barrage can be determined to be the second priority. Wherein the first priority is higher than the second priority.
It should be noted that, although the manner of determining the priority of the target bullet screen according to the type of the target bullet screen is described above by way of example, those skilled in the art will appreciate that the present disclosure should not be limited thereto. The method for determining the priority of the target bullet screen according to the type of the target bullet screen can be flexibly set by a person skilled in the art according to the requirements of the actual application scene and/or personal preferences.
In another possible implementation, the priority of the target barrage may be set manually.
This embodiment is through the first speed that confirms target barrage corresponds to confirm the show speed of target barrage according to the priority of first speed and target barrage, can set up the show speed of target barrage in a flexible way according to the priority of target barrage from this, can make the barrage of high priority obtain the show of longer time, avoid the barrage of high priority also to pass, thereby can improve the bandwagon effect of high priority barrage, utilize high priority barrage to reach better interactive effect.
Fig. 2 shows an exemplary flowchart of the step S12 of the bullet screen speed control method according to an embodiment of the disclosure. As shown in fig. 2, step S12 may include step S121 and step S122.
In step S121, a second speed corresponding to the target bullet screen is determined according to the priority of the target bullet screen, where the second speed is positively correlated to the priority.
For example, if the priority of the target bullet screen is the first priority, the second speed corresponding to the target bullet screen may be greater than 0; if the priority of the target bullet screen is the second priority, the second speed corresponding to the target bullet screen may be equal to 0. Wherein the first priority is higher than the second priority.
In step S122, the difference between the first speed and the second speed is used as the display speed of the target bullet screen.

In step S123, an adjustment ratio corresponding to the target bullet screen is determined according to the priority of the target bullet screen, where the adjustment ratio is greater than 0 and less than or equal to 1, and the adjustment ratio is negatively related to the priority.
For example, if the priority of the target bullet screen is the first priority, the adjustment ratio corresponding to the target bullet screen may be smaller than 1; if the priority of the target bullet screen is the second priority, the adjustment ratio corresponding to the target bullet screen may be equal to 1. Wherein the first priority is higher than the second priority.
