Step S101: the terminal obtains an original subtitle queue, the original subtitle queue includes at least one first original subtitle, and the first original subtitle is a subtitle with an end time.

In this embodiment of the present application, the original subtitle queue includes one or more original subtitles, and each original subtitle has a start time. Wherein, the one or more original subtitles include at least one first original subtitle. In this embodiment of the present application, the first original subtitle refers to a subtitle with an end time. When the original subtitle queue includes multiple subtitles, the multiple subtitles may include at least one second original subtitle in addition to at least one first original subtitle. In this embodiment of the present application, the second original subtitle refers to a subtitle without an end time.

When the original subtitle queue contains multiple original subtitles, the multiple original subtitles are arranged in order of start time, thereby forming the original subtitle queue. Wherein, the first original subtitles and the second original subtitles may be arranged alternately, which is not limited in this embodiment of the present application.

Step S102: the terminal performs a split operation on the first original subtitle in the original subtitle queue to obtain the first type subtitle and the second type subtitle.

In the embodiment of the present application, after acquiring the original subtitle queue, the terminal performs a split operation on the first original subtitle included in the original subtitle queue. It should be noted that, in the embodiment of the present application, when the original subtitle queue includes multiple first original subtitles, the terminal may perform a split operation on each of all the first original subtitles included in the original subtitle queue, or may The splitting operation is only performed on part of the first original subtitles in all the first original subtitles, which is not limited in this embodiment of the present application.

In this embodiment of the present application, taking any one of the first original subtitles as an example, the terminal performs a split operation on the first original subtitle to obtain the first type subtitle and the second type subtitle. Wherein, both the first type subtitle and the second type subtitle are subtitles without end time; the start time of the first type subtitle is the start time of the first original subtitle, and the subtitle type of the first type subtitle is the first type , the first type is used to indicate that the first type of subtitle contains the subtitle content of the first original subtitle, and the first type of subtitle is used to render the subtitle content into an image; the start time of the second type of subtitle is the first An end time of the original time, and the subtitle type of the second type of subtitle is the second type, and the second type is used to indicate that no subtitle content is rendered for the second type of subtitle, and a canvas cleaning operation is performed.

For example, assuming that the first original subtitle is played for 5s-10s and named Sub[5,10], that is, the start time of the first original subtitle Sub[5,10] is the 5th s, and the end time is the 10th s. Perform a split operation on the first original subtitle to obtain the first type of subtitle Sub1[5, *] and the second type of subtitle Sub2[10, *], where * means no end time; the subtitle type of the first type of subtitle Sub1[5, *] is the first type, and the first type can be identified by content; Type II subtitle Sub1[10, *] subtitle type is the second type, and the second type can be identified by cleanup. As shown in Table 1, it is a definition table of a subtitle type provided by the embodiment of the present application. It should be noted that what is shown in this table is only an illustration of the first type and the second type. In practical applications, other types and numbers of subtitle types may also be included, which is not limited in this embodiment of the present application.

Table 1 Definition of subtitle types

字幕类型（subtitle） subtitle type (subtitle)	定义 definition
第一类型（content） The first type (content)	将字幕内容渲染为图像 Render subtitle content as image
第二类型（cleanup） The second type (cleanup)	无内容渲染，立即清除屏幕内容 Render without content, immediately clear screen content

Step S103: the terminal generates a target subtitle queue according to the first type of subtitle and the second type of subtitle.

In this embodiment of the present application, the terminal performs a split operation on each of the first original subtitles in all or part of the first original subtitles included in the original subtitle queue to obtain the first type of subtitles corresponding to each first original subtitle After subtitles of the second type are combined, a target subtitle queue corresponding to the original subtitle queue is generated according to the first type subtitle and the second type subtitle corresponding to each of the first original subtitles in all or part of the first original subtitles.

Optionally, in this embodiment of the present application, when the terminal performs a split operation on each first original subtitle in all the first original subtitles included in the original subtitle queue, the target subtitle queue contains all the first original subtitles The first type subtitle and the second type subtitle corresponding to each first original subtitle in . When the original subtitle queue also contains one or more second original queues, the target subtitle queue still contains the one or more second original queues, and each first original subtitle in all the first original subtitles corresponds to The subtitles of the first type and the subtitles of the second type, and the one or more second original queues are arranged according to the starting time.

Optionally, in this embodiment of the present application, when the terminal performs a split operation on each of the first original subtitles in the part of the first original subtitles included in the original subtitle queue, the target subtitle queue contains the part of the first original subtitles The first type subtitle and the second type subtitle corresponding to each first original subtitle in . In this case, the target subtitle queue also includes another part of the first original subtitles for which the split operation has not been performed, and each first original subtitle in the target subtitle queue for which the split operation has been performed corresponds to The subtitles of the first type, the subtitles of the second type, and the other part of the first original subtitles for which no splitting operation has been performed are arranged in sequence according to the start time of each subtitle. Optionally, when the original subtitle queue also contains one or more second original queues, the target subtitle queue still contains the one or more second original queues, and the first original subtitles that have been split The subtitles of the first type and the subtitles of the second type corresponding to each first original subtitle, the other part of the first original subtitles for which the split operation has not been performed, and the one or more second original subtitles Time is arranged.

Embodiment 1 By parsing the first original subtitle with an end time from the original subtitle queue, performing a split operation on the first original subtitle to obtain the first type of subtitle and the second type of subtitle without an end time, thereby finally generating the original subtitle queue Corresponding to the target subtitle queue, since all subtitles in the target subtitle queue only have the start time, the control logic of subtitles can be simplified.

As shown in FIG. 2 , it is a flowchart of the steps of the subtitle processing method provided by Embodiment 2 of the present application. The method comprises the steps of:

Step S201: the terminal obtains an original subtitle queue, the original subtitle queue includes at least one first original subtitle, and the first original subtitle is a subtitle with an end time.

In the embodiment of the present application, step S201 can be understood by referring to the relevant content of step S101 in the first embodiment, and will not be repeated here.

Step S202: judging whether the first original subtitle satisfies the splitting condition.

In this embodiment of the present application, after acquiring the original subtitle queue, the terminal first judges each of the one or more first original subtitles included in the original subtitle queue, and judges whether each first original subtitle The split condition is met.

Optionally, the splitting condition in this embodiment of the present application may include: the time interval between the end time of the first original subtitle and the start time of the next subtitle is greater than a preset time. That is, when the time interval between the end time of a certain first original subtitle and the start time of the next subtitle is greater than a preset time, it is determined that the first original subtitle satisfies the splitting condition. For example, the preset time may be any one of 30 milliseconds to 50 milliseconds. Assuming that the preset time is set to 40 ms, if the time interval between the end time of a certain first original subtitle and the start time of the next subtitle is greater than 40 ms, it is determined that the first original subtitle meets the splitting condition.

Optionally, the splitting condition in this embodiment of the present application may include: the first original subtitle is the last subtitle in the original subtitle queue. That is, when a certain first original subtitle is the last subtitle in the original subtitle queue, the first original subtitle meets the splitting condition.

Step S203: When the splitting condition is met, perform a splitting operation on the first original subtitle to obtain the first type subtitle and the second type subtitle.

In this embodiment of the present application, the terminal executes the splitting condition on each first original subtitle satisfying the splitting condition, so as to obtain the first type subtitle and the second type subtitle respectively corresponding to each first original subtitle. Specifically, step S230 can be understood by referring to the relevant content of step S102 in the first embodiment, and will not be repeated here.

Step S204: When not satisfied, adjust the end time of the first original subtitle to obtain the first target subtitle, and the end time of the first target subtitle is the start time of the next subtitle; or, when not satisfied, adjust the next subtitle The start time of a subtitle is adjusted to obtain a second target subtitle, and the start time of the second target subtitle is the end time of the first original subtitle.

In this embodiment of the application, when the first original subtitle does not meet the splitting condition, for example, the time interval between the end time of the first original subtitle mentioned in step S202 and the start time of the next subtitle is less than or equal to the preset time, the first original subtitle is not split, but the first original subtitle is adjusted to obtain the first target subtitle, that is, the end time of the first original subtitle that does not meet the split condition is adjusted to the end time of the next subtitle start time. Or, when the first original subtitle does not meet the splitting condition, the first original subtitle is not split, but the next subtitle is adjusted to obtain the second target subtitle, that is, the start time of the next subtitle is adjusted to the The end time of the first raw subtitle.

In the embodiment of the present application, since the second type of subtitle is to perform canvas cleaning, when the time interval between the end time of the first original subtitle and the start time of the next subtitle is small, the screen that performs canvas cleaning is likely to generate a splash screen. Therefore, for this first original subtitle that does not meet the splitting condition, splitting is not performed, but by adjusting the end time of the first original subtitle with an end time to be the same as the start time of the adjacent subtitle, that is, when the first original subtitle When a subtitle ends, an adjacent subtitle begins. Therefore, in terms of the time axis, connecting the first subtitle and the adjacent subtitle without time difference can prevent flickering of the screen.

Step S205: Based on the first type of subtitles and the second type of subtitles, generate a target subtitle queue corresponding to the original subtitle queue.

In the embodiment of the present application, step S205 can be understood by referring to the relevant content of step S103 in the first embodiment, and will not be repeated here.

Embodiment 2 By parsing the first original subtitle with an end time from the original subtitle queue, performing a split operation on the first original subtitle to obtain the first type of subtitle and the second type of subtitle without an end time, thereby finally generating the original subtitle queue Corresponding to the target subtitle queue, since all subtitles in the target subtitle queue only have the start time, the control logic of subtitles can be simplified. Different from the first embodiment, the second embodiment can also realize the advantage of preventing the splash screen.

As shown in FIG. 3 , it is a flowchart of the steps of the subtitle processing method provided by the third embodiment of the present application. The method comprises the steps of:

Step S301: the terminal obtains an original subtitle queue, the original subtitle queue includes at least one first original subtitle, and the first original subtitle is a subtitle with an end time.

Step S302: performing a split operation on the first original subtitle to obtain a first type subtitle and a second type subtitle.

Step S303: Based on the first type of subtitles and the second type of subtitles, generate a target subtitle queue corresponding to the original subtitle queue.

In the embodiment of the present application, steps S301 to S303 can be understood by referring to the relevant content of steps S101 to S103 in the first embodiment, and will not be repeated here.

Step S304: Determine the subtitle type of the currently dequeued subtitle, the currently dequeued subtitle is any subtitle in the target subtitle queue.

Step S305: According to the subtitle type of the currently dequeued subtitle, render the currently dequeued subtitle to obtain a target canvas.

In this embodiment of the present application, when the subtitle type of the currently dequeued subtitle is the first type, the target canvas is the canvas obtained by rendering the subtitle content of the currently dequeued subtitle, and when the current When the subtitle type of the dequeued subtitle is the second type, the target canvas is a canvas obtained by performing a canvas cleaning operation.

Step S306: Compare whether the current playback progress time is greater than the start time of the current out-of-queue subtitle.

Step S307: If yes, display the target canvas.
