Obviously, the described embodiments are only part of the embodiments described in the present application, not all of the embodiments.

[0041] In the specification and claims of this application and the above-mentioned drawings, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "multiple" means two or more. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0042] Figure 1 FIG. 1 is a flowchart of a subtitle processing method according to an embodiment of the present application. Figure 1 As shown, the subtitle processing method of the embodiment of the present application includes the following steps:

[0043] S101: Acquire attribute data of a subtitle entry;

[0044] Existing non-linear editing systems usually use a template-based subtitle usage method, which encapsulates the basic attributes and animation effects of subtitles into a template and applies them to subtitles. Each subtitle has a corresponding attribute template and animation template. When rendering subtitles, the corresponding template can be directly read to generate the effect.

[0045] Subtitles are short and frequently switched elements in videos, and the basic properties and animation effects of subtitles do not change in most stages. Therefore, saving a template for each subtitle will result in a large amount of duplicate redundant data, a waste of memory, and repeated operations for template maintenance, which consumes performance.

[0046] In the subtitle file stored, there are different subtitle item entities, each of which stores a subtitle, and the order is expressed in the form of subscripts and levels, and corresponds to the start time and end time of the subtitle. Each item entity corresponds to its attribute data.

[0047] Therefore, in the subtitle processing method provided in the embodiment of the present application, it is first necessary to obtain the attribute data of the subtitle entry. Specifically, it is first necessary to import a subtitle file in the srt format and store the subtitle file as a subtitle entity. Then, the subtitle entry is obtained in the stored subtitle entity, and the attribute data of the subtitle entry is obtained.

[0048] S102: performing deduplication processing on the attribute data of the subtitle entry and mapping the attribute data with the subtitle entry; and

[0049] As mentioned above, each entry entity of the subtitle file has its attribute data. Therefore, after obtaining the attribute data of the subtitle entry, it is necessary to deduplicate the attribute data and map it with the corresponding subtitle entry to avoid storing duplicate redundant data and reduce memory waste.

[0050] S103: batch processing the subtitle entries according to the attribute data after deduplication processing and the subtitle entries mapped thereto.

[0051] Specifically, after the attribute data of the subtitle entry is deduplicated and mapped with the subtitle entry, if the attribute data corresponding to the subtitle entry is modified and then the modified attribute data is transferred to the subtitle entry, the subtitle entries with the same attribute data can be batch processed.

[0052] Therefore, in the subtitle processing method provided in the embodiment of the present application, the attribute data of the subtitle entry is first obtained, and then the attribute data of the subtitle entry is deduplicated and mapped with the subtitle entry, and finally the subtitle entries are batch processed according to the deduplicated attribute data and the subtitle entry mapped with it. The subtitle processing method provided in the embodiment of the present application, after deduplicating the attribute data of the subtitle entry and mapping it with the subtitle entry, if the attribute data corresponding to the subtitle entry is modified, and then the modified attribute data is passed to the subtitle entry, it is possible to realize batch processing of subtitle entries with the same attribute data, which can reduce memory consumption and improve the processing speed of subtitles.

[0053] Furthermore, in some embodiments of the present application, further, batch processing the subtitle entries according to the attribute data after deduplication processing and the subtitle entries mapped thereto includes:

[0054] Obtaining index data of the subtitle entry corresponding to the attribute data; and

[0055] The subtitle entries are batch processed according to the index data and the modification attributes of the subtitle entries.

[0056] Specifically, each subtitle entry entity contains a subtitle and its corresponding start time, end time, subscript and level information. The subscript here is the index data or index array of the subtitle entry. When the subtitle entries are batch processed according to the deduplicated attribute data and the subtitle entries mapped thereto, it is first necessary to obtain the index data of the subtitle entries corresponding to the attribute data, and batch process the subtitle entries according to the index data and modified attributes of the subtitle entries, thereby realizing fast batch processing of subtitles.

[0057] Furthermore, after batch processing the subtitle entries according to the index data and modification attributes of the subtitle entries, the method further includes:

[0058] The attribute data of the subtitle entry is refreshed and mapped with the subtitle entry.

[0059] Specifically, after batch processing the subtitle entries according to the index data and modification attributes of the subtitle entries, it is necessary to provide the index array and modification attributes of the corresponding subtitle entries to the data layer through the data layer interface at the business level, and at the data layer, perform batch settings and template refresh according to the index array and attributes of the subtitle entries, and map them with the corresponding subtitle entries, so as to ensure that the attribute data of the subtitle entries can correspond to the subtitle entries for subsequent processing.

[0060] Furthermore, the refreshing of the attribute data of the subtitle entry and mapping with the subtitle entry includes:

[0061] Writing back the attribute data of the subtitle entry; and

[0062] The attribute data is deduplicated and hash-mapped with the subtitle entry.

[0063] Specifically, as described above, after batch processing the subtitle entries according to the index data and modification attributes of the subtitle entries, Figure 2 As shown, the attribute data of the subtitle entry needs to be refreshed and mapped with the subtitle entry, that is, the attribute data of the subtitle entry needs to be written back, deduplicated, and hash mapped with the subtitle entry, so that the corresponding subtitle entry can be quickly retrieved through the attribute data of the subtitle entry.

[0064] Hash map is a data structure implemented using hash table, which stores data in key-value pairs and allows fast retrieval of corresponding values ​​by key. The basic working principle of hash map is to map a key to an index position through hash function, so as to achieve fast data access. Unlike linear table structures such as arrays, hash map directly locates the data by calculating the hash value of the key, which greatly improves the efficiency of data retrieval.

[0065] Further, refer to Figure 3 The attribute data of the subtitle entry includes an attribute template and an animation template, and the subtitle entry is batch processed according to the attribute data after deduplication processing and the subtitle entry mapped thereto, including:

[0066] Obtaining an all-inclusive template and / or a non-all-inclusive template of the subtitle entry;

[0067] For the all-inclusive template, modifying the template attributes; and

[0068] For the non-fully inclusive template, the template attributes are modified after cloning.

[0069] Specifically, the fully inclusive template means that the subscripts of all subtitle entries using the template are included in the passed index array, while non-fully inclusive means incomplete inclusion. For the fully inclusive module, its template properties can be directly modified, while the non-fully inclusive template clones the template to modify the properties, thereby enabling batch processing of subtitle entries with the same attribute data, reducing memory consumption, and increasing the processing speed of subtitles.

[0070] Furthermore, before acquiring the attribute data of the subtitle entry, the method further includes: traversing the subtitle entry to ensure that each subtitle entry can be retrieved to improve the accuracy of subtitle processing.

[0071] Furthermore, before traversing the subtitle entries, the method further includes:

[0072] The index data of the subtitle entry is divided by time slices.

[0073] That is, in order to improve the traversal speed of subtitle entries, a subtitle entry cache is added. The subtitle processing method provided by the embodiment of the present application implements fast access to subtitle entries by dividing the index of the subtitle entry by time slices, for example, dividing the start time of the subtitle entry by 10 seconds to obtain the segment start value of the subtitle entry.

[0074] Figure 4 2 is a block diagram of a subtitle processing device 200 provided in an embodiment of the present application. Figure 4As shown, the subtitle processing device 200 of the embodiment of the present application includes: an attribute acquisition module 210, a subtitle mapping module 220 and a batch processing module 230, wherein:

[0075] The attribute acquisition module 210 is used to acquire attribute data of a subtitle entry;

[0076] A subtitle mapping module 220, configured to perform deduplication processing on the attribute data of the subtitle entry and map it with the subtitle entry; and

[0077] The batch processing module 230 is used to batch process the subtitle entries according to the attribute data after deduplication processing and the subtitle entries mapped thereto.

[0078] In the subtitle processing device provided in the embodiment of the present application, the attribute data of the subtitle entry is first obtained, and then the attribute data of the subtitle entry is deduplicated and mapped with the subtitle entry, and finally the subtitle entries are batch processed according to the deduplicated attribute data and the subtitle entry mapped with it. The subtitle processing method provided in the embodiment of the present application deduplicates the attribute data of the subtitle entry and maps it with the subtitle entry, and then, if the attribute data corresponding to the subtitle entry is modified, and then the modified attribute data is passed to the subtitle entry, it is possible to realize batch processing of subtitle entries with the same attribute data, reduce memory consumption, and improve the processing speed of subtitles.
