[0071] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0072] In one embodiment, as shown in FIG1, a caption display method is provided. Although the logical order is shown in the step diagram, in some cases, the steps shown or described may be performed in a different order than that shown in the figures. Specifically, this caption display method can be applied to a terminal, wherein the terminal may include, but is not limited to, one or more of smartphones, tablets, laptops, desktop computers, and in-vehicle computers.
[0073] The following sections provide detailed descriptions of each example. It should be noted that the order in which the embodiments are described is not intended to limit the priority of the embodiments.
[0074] According to the subtitle display method shown in Figure 1, the method includes at least steps S110 to S160, which are described in detail below: In step S110, the target font of the target character corresponding to the subtitle to be displayed is determined.
[0075] The subtitle to be displayed can be any subtitle containing characters. Characters can be characters with multiple font options, characters from various languages, or other symbols. Font refers to the style and form of the characters; it is the external representation of the characters. The target character can be any character, and the target font can be any font. The fonts of the individual characters in the subtitle to be displayed can be the same or different.
[0076] Optionally, determining the target font of the target character of the subtitle to be displayed may include: acquiring the target character of the subtitle to be displayed when the playback process starts; and determining the target font required to display the target character.
[0077] It can retrieve the target characters from the subtitle file when the playback process corresponding to the subtitle starts, and determine the target font required to display the target characters.
[0078] In one embodiment, the target characters can be words such as "T" and "good", or various punctuation marks; each target character can have multiple fonts, such as regular script, Times New Roman, or boldface, etc. The shapes of the same character displayed in different fonts are different. When displaying the target characters of the subtitle, it is necessary to determine which font to display the target characters in specifically. Therefore, it is necessary to determine the target font required to display the target characters.
[0079] Adopting the technical solution of the embodiment of the present application can quickly display subtitles. Therefore, determining the target font of the target characters when the playback process starts, compared with determining the target font of the target characters in advance before the playback process starts, can avoid waste of resources caused by not playing subtitles subsequently without affecting subtitle display.
[0080] In step S120, query the target font corresponding to the target character in the index table.
[0081] Among them, the index table includes: multiple characters, multiple fonts corresponding to the multiple characters, and the storage paths of the multiple characters of each font.
[0082] The fast display of subtitles can be achieved by using the font configuration software tool (Fontconfig). The font set supported by the fonts file of the font configuration software tool is specified; the storage paths of each character of each font are specified in the cache file of the font configuration software tool.
[0083] The index table can be pre-generated and stored in the cache file. As shown in Table 1, the index table at least includes: multiple characters, multiple fonts corresponding to each character, and the storage paths of each character of each font. The font corresponding to a character refers to the font that the character has. Optionally, the index table can also include the font library files where the characters of each font are located, etc.
[0084] Table 1. Index Table
[0085] It can be seen from Table 1 that the character T has multiple fonts such as Courier, Tiresias, and Open Sans. Among them, the character T of the Courier font is stored in the font library file "cour.ttf", and the storage path of the character T of the Courier font is " / data / tcluniplayer / fontconfig / font / cour.ttf".
[0086] Optionally, the characters in the index table can be sorted in order, and the fonts corresponding to each character can also be sorted in order to speed up the query speed of the index table.
[0087] When the player process starts, it checks the availability of the font configuration software tool. If the software tool is available and the index table exists in the cache file, the pre-generated index table can be retrieved directly from the cache file. If the index table does not exist, it is rebuilt based on the set of font files in the fonts file.
[0088] The target font corresponding to the target character refers to the target font that the target character belongs to. As shown in Table 1, Courier, Tiresias, and Open Sans are the fonts corresponding to the character T.
[0089] Optionally, the step of querying the target font corresponding to the target character in the index table may include: querying the target character in the index table; and when the target character is found in the index table, querying whether each font corresponding to the target character contains the target font.
[0090] The system checks if the target character exists in the index table. If the target character does not exist in the index table, then the target font corresponding to the target character also does not exist.
[0091] If the target character exists in the index table, then you can query whether the target font corresponding to the target character exists among the multiple fonts corresponding to the target character.
[0092] Because the characters in the index table are sorted in order, and the fonts corresponding to each character are also sorted in order, when querying whether the target character exists in the index table, and whether the target font exists in the fonts corresponding to the target character, the search can be performed in order.
[0093] In this way, by querying the index table to see if the target font corresponding to the target character exists, it is possible to quickly determine whether the font file corresponding to the index table contains the target font corresponding to the target character.
[0094] In step S130, when the target font corresponding to the target character is found in the index table, the target storage path of the target character of the target font is obtained.
[0095] When the target font corresponding to the target character is found in the index table, the target storage path of the target character of the target font can be directly obtained from the index table.
[0096] In step S140, the target characters of the target font are obtained according to the target storage path.
[0097] The target characters of the target font can be obtained directly by following the target storage path.
[0098] In step S150, the subtitle is displayed according to the target character of the target font.
[0099] After obtaining the target characters for the target font, the target characters can be displayed. Similarly, after obtaining the target characters for each target font in the subtitle, the subtitle can be displayed.
[0100] The technical solution adopted in this application embodiment contains multiple characters, multiple fonts corresponding to the multiple characters, and the storage paths of the multiple characters in each font. Therefore, querying the index table can quickly obtain the target storage path of the target character of the target font; thus, it is not necessary to open each font file sequentially to find the target character of the target font, but can directly obtain the target character of the target font according to the target storage path, and quickly complete the display of subtitles. In this way, the time to obtain the target character of the target font can be greatly shortened, the display speed of subtitles can be accelerated, and the display efficiency of subtitles can be improved.
[0101] Based on the above technical solution, as an embodiment, as shown in Figure 2, before querying the target font corresponding to the target character in the index table, the method may further include steps S210 to S250.
[0102] In step S210, the character set is obtained.
[0103] In step S220, each font file in the font set is traversed to obtain each character of each font.
[0104] A font set consists of multiple font files, each containing characters from various fonts. By iterating through the font files in the font set, you can obtain the individual characters from each font.
[0105] In step S230, based on the individual characters of each font, the font corresponding to each character is determined. By organizing the individual characters of each font according to their order, the font corresponding to each character can be determined.
[0106] For example, if there are characters T in the Courier font, T in the Tiresias font, T in the Open Sans font, L in the Courier font, and L in the Tiresias font, then it can be determined that character T has the following three fonts: Courier, Tiresias, and Open Sans; and character L has the following two fonts: Courier and Tiresias.
[0107] In step S240, the storage path of each character in each font is determined according to the storage path of each character in each font file.
[0108] Each character in each font is obtained from a different font file. Therefore, the storage path of each character in each font can be determined based on the storage path of the font file containing each character.
[0109] In step S250, the index table is generated based on each character, the corresponding font, and the storage path of each character in each font.
[0110] The index table is generated based on each character, the corresponding font, and the storage path of each character in each font. This can be achieved by storing the characters, their corresponding fonts, and the storage paths of each character in each font in a corresponding manner, generating the index table as shown in Table 1.
[0111] Optionally, the characters in the index table can be sorted in order, and the fonts corresponding to each character can also be sorted in order to speed up the query of the index table.
[0112] The technical solution adopted in this application involves traversing each font file in the font library set to obtain each character of each font, and then redirecting each character of each font to generate an index table. Subsequently, the storage path of each character of each font can be directly determined from the index table, enabling fast lookup of each character of each font and thus accelerating the display speed of subtitles. Furthermore, the characters and fonts in the index table are sorted sequentially, which further speeds up the index table lookup.
[0113] Based on the above technical solution, as an embodiment, Figure 3 is a flowchart illustrating a subtitle display method provided in an embodiment of this application. As shown in Figure 3, after querying the target font corresponding to the target character in the index table, the method may further include: when the target font corresponding to the target character is not found in the index table, obtaining a font library set; querying the target character of the target font in each font file of the font library set; when the target character of the target font is found in each font file of the font library set, obtaining the target character of the target font; and displaying the subtitle according to the target character of the target font.
[0114] If the target font corresponding to the target character cannot be found in the index table, it is necessary to query each font file in the font set to see if it contains the target character of the target font. The font set is obtained, and each font file in the font set is traversed until the target character of the target font is found.
[0115] When the target character of the target font is found in the font file of the font set, the subtitle is displayed based on the target character of the target font in that font file.
[0116] Using the technical solution of this application embodiment, when the storage path of the target character of the target font does not exist in the index table, the target character of the target font can be found by traversing each font file in the font library set, so as to avoid affecting the display of subtitles. Based on the above technical solution, as an embodiment, as shown in Figure 3, after searching for the target character of the target font in each font file in the font library set, the method may further include: when the target character of the target font is found in each font file in the font library set, deleting the index table; and generating a new index table. If the target font corresponding to the target character cannot be found in the index table, but the target character of the target font is found in each font file in the font library set, it proves that the target character of the newly added target font exists in the font library set. Therefore, it is necessary to update the index table or generate a new index table.
[0117] In one embodiment, a thread can be created to delete the existing index table and generate a new index table. The method for generating the new index table can be referred to steps S210 to S250, and will not be described in detail here.
[0118] In another embodiment, the character set can be traversed to obtain the characters of the newly added fonts, and the original index table can be incrementally updated based on the characters of the newly added fonts.
[0119] By adopting the technical solution of this application embodiment, when there are newly added characters of a font in the font library set, the index table is updated or a new index table is generated so that when obtaining other characters of other fonts in the future, the storage path of the required font characters can be quickly obtained according to the new index table.
[0120] Based on the above technical solution, as an embodiment, as shown in Figure 3, after querying the target character of the target font in each font file of the font set, the method may further include: when the target character of the target font cannot be found in each font file of the font set, determining the target character of the target font as a reference character; and displaying the subtitle according to the reference character.
[0121] If the target font corresponding to the target character cannot be found in the index table, and the target character of the target font cannot be found in any of the font files in the font set, it proves that the target character of the target font does not exist in any of the current font files.
[0122] To prevent a single target character from affecting the display of the entire subtitle, the target character of the target font can be designated as a reference character. The reference character can be "□".
[0123] When displaying target characters in subtitles, reference characters can be used as a substitute. When users see the reference characters, they can determine that there are characters that are not displayed correctly at the location of the reference characters.
[0124] By using the technical solution of this application embodiment, a reference character is used to replace the target character for display. This can inform the user that there is a character that is not displayed correctly at the location of the reference character, so that the user can obtain the meaning of the target character by referring to the context, thereby reducing the impact on the viewing experience.
[0125] Optionally, as an embodiment, if the target font corresponding to the target character cannot be found in the index table, and the target character of the target font cannot be found in any of the font files in the font set, the target character of other fonts can be obtained. When displaying the target character of the subtitle, the target character of other fonts is displayed. Although the display effect of displaying the target character of other fonts is not as good as that of the target character of the target font, it still allows the user to obtain the semantics of the target character, thereby reducing the impact on the user's viewing experience.
[0126] Figure 3 is a flowchart illustrating a subtitle display method according to an embodiment of this application. As shown in Figure 3, in step S310, subtitle rendering begins. In step S320, the index table is checked to see if a target character of the target font exists. If the target character of the target font exists in the index table, the process jumps to step S330; if the target character of the target font does not exist in the index table, the process jumps to step S340.
[0127] In step S330, the storage path is obtained, and the target characters of the target font are retrieved based on the storage path. The storage path is the storage path of the target characters of the target font stored in the index table. Based on the storage path, the font file storing the target characters of the target font can be directly determined, and then the target characters of the target font can be directly retrieved from that font file. The subtitles are then displayed based on the retrieved target characters of the target font.
[0128] In step S340, the font set is traversed to check if the target character of the target font exists. If the target character of the target font exists in the font set, steps S350 and S360 are executed; if the target character of the target font does not exist in the font set, step S370 is executed.
[0129] In step S350, the target character of the target font is obtained from the font set. In step S360, a new index table is generated. If the target character of the target font exists in the font set, it is obtained from the font set to display the subtitles. If the target character of the target font exists in the font set but cannot be found in the index table, it indicates that the font set has been updated; therefore, a new index table is generated based on the current font set.
[0130] In step S370, the target character of the target font is displayed as a reference character. To avoid a single target character affecting the display of the entire subtitle, the target character of the target font can be designated as a reference character.
[0131] By adopting the technical solution of this application embodiment, the time to obtain the target character of the target font can be greatly shortened, the display speed of subtitles can be accelerated, and the display efficiency of subtitles can be improved.
[0132] To facilitate better implementation of the subtitle display method of this application, this application also provides a subtitle display device based on the above-described subtitle display method.
