Detailed Description
The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.
In order to dynamically adjust the sliding time of each bullet screen, the embodiment of the invention provides a bullet screen display method, a display device and electronic equipment.
In the existing bullet screen display method, when a client displays bullet screens in a video, each bullet screen is generally displayed at a fixed sliding speed. The bullet screen has a certain length, when the bullet screen is displayed in a sliding mode, the head of the bullet screen usually slides from one side boundary of the video to appear, then slides to the other side boundary of the video until the tail of the bullet screen slides out of the boundary, and the bullet screen sliding display is completed. Because the length of each bullet screen is different, the sliding speed of the bullet screen is fixed, in the existing bullet screen display method, the sliding time of the bullet screen only changes along with the length rule of the bullet screen, when the bullet screen is long, the sliding time is prolonged, when the bullet screen is short, the sliding time is shortened, and the sliding time of the bullet screen cannot be dynamically adjusted according to the number of user comments received by a client. When a user publishes a large number of comments in a short time, the evaluation information of the user is overstocked, the user can display the barrage content published by the user after the plot is passed for a long time, and the user experience is poor.
Generally, in a bullet screen display method provided by an embodiment of the present invention, first, when caching each received character string, determining the number of currently cached character strings, and when converting a character string into a bullet screen, determining a display length of the bullet screen; and then, determining the sliding time of the bullet screen based on the determined number of the cached character strings and the display length of the bullet screen. Because the number of the current cached character strings is a dynamically changing numerical value, when the sliding time of each bullet screen is determined, the sliding time of each bullet screen can be dynamically adjusted by the client, so that overstocked user evaluation information is avoided, a user can see the published bullet screen in time, and the use experience of the user is improved.
Method embodiment
As shown in fig. 1, an embodiment of the present invention provides a bullet screen display method, which may be applied to a client that plays a video, and may also be applied to other types of devices having a data processing and computing function, where the process may include the following steps:
s101, caching the received character strings containing the comment information, and determining the number of the cached character strings when caching the character strings aiming at each character string.
In the embodiment of the present invention, the character string received by the client and sent by the server may be a binary character string in a JSON (JSON Object Notation) data format, where the JSON data format is a lightweight data exchange format. The above character string may carry comment information itself issued by the user, and information such as the user name, the user rank, the priority of the character string, and the like. As can be seen from the above, the character string received by the client includes not only the comment information but also other information. For example, the degree of importance of the comment information can be determined by the user name and the user rank corresponding to the comment information in the character string. Specifically, when the user level is a high level, the importance degree of the corresponding comment information is high.
In general, a client receives a plurality of character strings transmitted one by a server, and then buffers the received character strings. Specifically, the client may cache the received character strings in the form of a linked list. The character strings cached in the linked list can be extracted for bullet screen display, so that the caching quantity is reduced, and the caching quantity is increased by newly caching the character strings, so that the cached character strings are dynamic values. When caching a plurality of received character strings, the client can cache one character string every time, and determine the number of the character strings which are cached currently when caching the character strings once. The process of determining the number of the cache character strings is simple arithmetic calculation, and has little influence on the processing performance of the client.
As an optional implementation manner of the method embodiment of the present invention, sometimes, because the number of the character strings received by the client is not large, the character strings may be directly converted without buffering and the bullet screen may be displayed. Specifically, a number threshold may be set, which may be the maximum number of character strings that the program developer can process in a unit time by the client, as determined by the client performance. If the number of the character strings received by the client in unit time is larger than or equal to a preset threshold value, caching the received character strings, processing the character strings according to the bullet screen display method provided by the embodiment of the invention, and displaying the bullet screen; and if the number of the received character strings in the unit time of the client is less than a preset threshold value, directly converting the received character strings into the bullet screen, and sliding and displaying the bullet screen according to a preset speed. Wherein the preset speed may be fixed.
And S102, extracting the cached character strings and analyzing comment information in the character strings.
In the embodiment of the invention, the cached character string can be extracted from the linked list, and the comment information in the character string can be analyzed.
As an optional implementation manner of the method embodiment of the present invention, the cached character strings may be extracted one by one according to the time sequence of caching the character strings. For example, if the cache time of the character string a is 1 point, the cache time of the character string B is 1 point 01 minutes, and the cache time of the character string C is 1 point 02 minutes, the character string a is extracted first, then the character string B is extracted, and then the character string C is extracted. The mode of extracting the character strings according to the cache time can ensure that the comment contents of all users are converted into the bullet screen and displayed.
As mentioned above, the string may carry priority information to indicate the priority level of the string. As another optional implementation manner of the embodiment of the present invention, if it is required to preferentially display the bullet screens of the important users, the plurality of cached character strings may be extracted according to the priority order of the character strings. For example, a character string with a higher priority is extracted first, and then a character string with a lower priority is extracted, so that the character string with the higher priority is converted into a bullet screen earlier than the character string with the lower priority, and the bullet screen is displayed earlier.
Optionally, the lowest priority string cached in the linked list may be purged at intervals to avoid backlogging of cached low priority strings.
S103, converting the obtained comment information into a bullet screen, determining the display length of the bullet screen, and caching the converted bullet screen.
In the embodiment of the present invention, the process of converting the comment information into the bullet screen can be implemented by the existing bullet screen generation method, and details are not repeated herein. It is easy to understand that after the comment information is converted into the bullet screen, the display pixel value (i.e., the display length) of the bullet screen can be determined naturally.
After the comment information is converted into the barrage, the converted barrage can be cached. Specifically, the client may also cache the barrage in a form of a linked list, and store information related to display of each barrage, such as display length and sliding time of each barrage, in the linked list.
S104, for each cached bullet screen, determining the sliding time of the bullet screen based on the determined number of the currently cached character strings and the display length of the bullet screen, wherein the sliding time of the bullet screen is reduced along with the increase of the determined number of the currently cached character strings and is increased along with the increase of the display length of the bullet screen.
In the embodiment of the present invention, it is easy to understand that if the number of the currently cached character strings is larger, it indicates that the bullet screen required to be displayed is larger, and if the display length of the bullet screen is longer, it indicates that the sliding distance required by the bullet screen is longer. Therefore, when the number of the character strings which are cached increases, in order to display the cached bullet screens as soon as possible, the sliding time of each bullet screen can be shortened.
Specifically, the slide time of the bullet screen can be determined by the following formula:
Figure BDA0001538994840000091
wherein, TiRepresenting the sliding time of the bullet screen; w represents the length of the display area of the bullet screen, and is usually set according to the display length of the video, and specifically may be represented by a pixel value, for example, if the resolution of one video is 640 × 480, which indicates that the display length of the video is 640 pixels, the length of the display area of the bullet screen may be determined to be 800 pixels; wiThe bullet screen display length is expressed, and specifically, the bullet screen display length can be expressed by pixel values; as shown in FIG. 2, W and WiThe sum is the sliding distance of the bullet screen; t ismaxRepresents the maximumThe number of character string caches is usually set according to the storage space of a client; b isnIndicating the number of the cached character strings; lambda [ alpha ]nA first coefficient, usually set to a constant value, may be determined according to the quotient of the historical average string buffer count and the maximum string buffer count; lambda [ alpha ]wThe second coefficient, which is usually set to a constant value, may be determined based on the quotient of the historical average bullet screen display length and the length of the bullet screen display area. Through the first coefficient and the second coefficient, the sliding time of the bullet screen can be adjusted.
And S105, sliding and displaying the cached bullet screens according to the determined sliding time of each bullet screen.
In the embodiment of the invention, after the cached sliding time of each bullet screen is determined, each bullet screen can be displayed in a sliding mode one by one according to the determined sliding time. For example, if the determined slide time is 3 seconds, the display length of the bullet screen a is 20 pixels, the length of the display area of the bullet screen is 640 pixels, and the slide distance of the bullet screen a is 660 pixels, it can be calculated that the slide display of the bullet screen a can be completed within 3 seconds when the bullet screen a slides at 220 pixels/second.
Based on the bullet screen display method shown in fig. 1, in an optional implementation manner of the method embodiment of the present invention, the step S105 slides and displays the cached bullet screen according to the determined sliding time of each bullet screen, as shown in fig. 3, specifically, the method may include:
s1051, according to the determined sliding time of the first bullet screen, the first bullet screen cached is displayed in a sliding mode.
S1052, after the first bullet screen slides its own length and a first distance, sliding the second bullet screen that shows the buffer memory, wherein the first distance is the non-overlapping minimum distance of the first bullet screen and the second bullet screen.
In the embodiment of the present invention, the first bullet screen and the second bullet screen are two bullet screens cached adjacently in the linked list, as shown in fig. 4, the caching time of the first bullet screen is earlier than that of the second bullet screen, so that the first bullet screen is displayed earlier than the second bullet screen. There is a possible case where two bullet screens are superimposed if a first bullet screen is displayed followed by a second bullet screen. To avoidThe first bullet screen can slide for at least the first distance WgAnd then, the cached second bullet screen is displayed in a sliding manner, so that a certain distance exists between the second bullet screen and the first bullet screen, and the condition that two bullet screens are overlapped can not occur.
As shown in fig. 5, the limit that the first bullet screen does not overlap with the second bullet screen is that when the first bullet screen is just displayed completely (i.e. the tail just slides out of the display area), the head of the second bullet screen is just next to the tail of the first bullet screen. If the first bullet screen and the second bullet screen are not overlapped, the following conditions need to be met:
Figure BDA0001538994840000111
wherein, WgRepresenting a first distance; w represents the length of the bullet screen display area, and is usually set according to the length of the video, and may be specifically represented by a pixel value; vaRepresenting the sliding speed of the first bullet screen; vbIndicating the sliding speed of the second bullet screen.
Further, the sliding speed of the first bullet screen is:

wherein, TaRepresenting the sliding display time of the first bullet screen; waIndicating the display length of the first bullet screen; w represents the length of the bullet screen display area;
the sliding speed of the second bullet screen is as follows:

wherein, TbRepresenting the sliding display time of the second bullet screen; wbIndicating the display length of the second bullet screen; w represents the length of the bullet screen display area;
then the first distance can be deduced as:

wherein, WgRepresenting a first distance; w represents the length of the bullet screen display area, and is usually set according to the length of the video, and may be specifically represented by a pixel value; waThe first bullet screen display length is expressed, and specifically, the first bullet screen display length can be expressed in pixel values; t isaRepresenting the sliding time of the first bullet screen; wbThe second bullet screen display length is expressed, and specifically, the second bullet screen display length can be expressed by pixel values; t isbIndicating the slide time of the second bullet screen.
When the first bullet screen starts to slide and display, the sliding distance is at least Wa+WgWhen the second bullet screen slides next to the back of the first bullet screen, the second bullet screen and the first bullet screen can be ensured not to be overlapped when the first bullet screen slides and disappears.
According to the bullet screen display method provided by the embodiment of the invention, when each received character string is cached, the number of the currently cached character strings is determined, when the character strings are converted into the bullet screen, the display length of the bullet screen is determined, and the sliding time of the bullet screen is determined based on the determined number of the cached character strings and the display length of the bullet screen.
