[0029] The exemplary embodiments will be described in detail herein with reference to the attached drawings. When the description below refers to accompanying drawings, unless otherwise noted, the same numbers in different drawings refer to the same or similar elements. The following exemplary embodiments described in the following detailed description are not meant to represent all embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0030] The present disclosure provides a multimedia file scanning method, device and terminal device to improve the scanning efficiency of multimedia files and reduce the scanning time.

[0031] The multimedia file scanning method and device provided by the present disclosure can be applied to a terminal device. For example, it can be applied to a mobile phone and the like.

[0032] The following specific embodiments are given to illustrate the technical solutions of the present disclosure in detail. The following specific embodiments can be combined with each other, and the same or similar concepts or processes can not be described in some embodiments.

[0033] Figure 1 is a flow chart of a multimedia file scanning method according to an exemplary embodiment of the present disclosure. Please refer to Figure 1The method provided by the embodiment can be applied to a terminal device and can include the following steps.

[0034] In S101, when receiving a multimedia file scanning request for a service provider multimedia database on the device, a target file path set that needs to be scanned by the scanning request is determined.

[0035] It should be noted that in an embodiment, the multimedia file scanning request is generated when it is detected that a photo album application on the device is started or returns to the foreground.

[0036] In another embodiment, the multimedia file scanning request is a multimedia file scanning request for an Android media database on the device, which is generated when it is detected that a file creation notification is reported by a third-party application.

[0037] It should be noted that when a file creation operation is detected, the third-party application reports a file creation notification to the terminal system. Further, the terminal system generates a multimedia file scanning request for the Android media database on the device based on the file creation notification reported by the third-party application, to perform multimedia file scanning based on the multimedia file scanning request for the Android media database on the device, and update the Android media database.

[0038] Further, the terminal system determines the multimedia file scanning request for the Android media database on the device as a multimedia scanning request for the service provider multimedia database on the device, to perform multimedia file scanning based on the multimedia scanning request and update the service provider multimedia database.

[0039] In addition, in still another embodiment, the multimedia file scanning request can be generated when it is detected that a photo album application on the device creates a file.

[0040] Specifically, the state of the photo album application can be listened to, and then when it is detected that the photo album application creates a file (for example, a new picture is generated by editing an original picture), a multimedia file scanning request is generated.

[0041] In addition, the target file path set is a file path that is newly added or deleted in the local file system compared with the service provider multimedia database. The specific implementation principle of determining the target file path set that needs to be scanned by the scanning request will be described in detail in the following embodiments, and will not be described here.

[0042] In S102, a plurality of final scanning tasks are generated according to the target file path set, wherein each final scanning task is used to instruct to scan a file under a target file path in the target file path set.

[0043] Specifically, for each target file path, it can be packaged into a final scanning task, which carries the target file path and is used to indicate scanning the files under the target file path. The specific implementation principle and implementation process of the packaging can refer to the description in the related art, which will not be described here.

[0044] It should be noted that when generating a final scanning task based on a target file path, if the files under the target file path are newly added files, a final scanning task of the type of newly added is generated, and if the files under the target file path are deleted files, a final scanning task of the type of deleted is generated.

[0045] S103, based on multiple scanning threads, processing each final scanning task in parallel to obtain a scanning result corresponding to each final scanning task, and inserting the scanning result into the service provider multimedia database.

[0046] For example, in an embodiment, the number of scanning threads is 4, that is, 4 final scanning tasks can be processed simultaneously at a time.

[0047] In addition, when inserting the scanning result into the service provider multimedia database, a batch processing method can be used to insert the scanning result into the service provider multimedia database.

[0048] Optionally, in a possible implementation, if several final scanning tasks carry the same file path, when processing the final scanning tasks, the several final scanning tasks can be processed by merging, that is, only one final scanning task can be retained. In this way, resources can be saved, the scanning efficiency can be further improved, and the scanning time can be reduced.

[0049] The method provided in this embodiment, when receiving a multimedia file scanning request for a service provider multimedia database on the device, determines a target file path set required to be scanned by the scanning request, and then generates multiple final scanning tasks according to the target file path set, so as to process each final scanning task in parallel based on multiple scanning threads to obtain a scanning result corresponding to each final scanning task, and insert the scanning result into the service provider multimedia database. Each final scanning task is used to indicate scanning the files under a target file path in the target file path set. In this way, by processing the final scanning tasks in parallel through multiple scanning threads, the scanning efficiency can be improved, and the scanning time can be reduced.

[0050] Figure 2 is a flowchart of another multimedia file scanning method according to an exemplary embodiment of the present disclosure. Please refer to Figure 2On the basis of the above-mentioned embodiments, the method provided in the embodiment can include the following steps.

[0051] S201, according to the identification information, find the processing strategy corresponding to the identification information from the pre-set correspondence between the identification information and the processing strategy; wherein the processing strategy includes a candidate file path set determination strategy.

[0052] Specifically, in the embodiment, the scanning request carries identification information, which is used to identify the triggering scenario of the scanning request. For example, when the scanning request is generated when it is detected that the photo application on the device is started or returned to the foreground, the identification information carried by the scanning request can be Y. When the scanning request is a multimedia file scanning request for the Android media database on the device generated when it is detected that the third-party application reports a file creation notification, the identification information carried by the scanning request can be Z. When the scanning request is generated when it is detected that the photo application on the device creates a file, the identification information carried by the scanning request can be X.

[0053] It should be noted that when the scanning request is a multimedia file scanning request for the Android media database on the device generated when it is detected that the third-party application reports a file creation notification, or when the scanning request is generated when it is detected that the photo application on the device creates a file, the scanning request also carries a file path (the file path can be a file path corresponding to a newly created file).

[0054] In addition, the pre-set correspondence between the identification information and the processing strategy is set according to actual needs, and the specific content of the embodiment is not limited.

[0055] For example, in an embodiment, when the identification information is Z or X, the corresponding candidate file path set determination strategy can be: obtaining all file paths under the file path carried by the scanning request from the local file system, and determining the obtained file paths as the candidate file path set.

[0056] For another example, in another embodiment, when the identification information is Y, the corresponding candidate file path set determination strategy can be: determining all file paths in the local file system as the candidate file path set.

[0057] Of course, in still another embodiment, when the identification information is Y, the corresponding candidate file path set determination strategy can be: determining all file paths corresponding to a specified third-party application (the specified third-party application is set according to actual needs, for example, it can be QQ, WeChat, etc.) existing in the local file system (the file path corresponding to the third-party application refers to a file path used to store data generated by the third-party application) and all file paths under a specified file path obtained from the local file system as the candidate file path set; wherein the specified file path can be the current file path of the service provider multimedia database and / or the newly added file path of the Android media database.

[0058] S202, determining the candidate file path set corresponding to the scanning request based on the candidate file path set determination strategy.

[0059] For example, in an embodiment, the identification information carried by the scanning information is Y, at this time, based on the candidate file path determination strategy given in the second example above, the candidate file path set corresponding to the scanning request can be determined according to the following method:

[0060] (1) For any specified third-party application, it is judged whether the storage space (used to store data generated by the third-party application) corresponding to the third-party application exists in the local file system, if it exists, all file paths in the local file system under the storage space are determined as the first candidate file path.

[0061] (2) For any file path currently existing in the service provider multimedia database, all file paths under the file path are obtained from the local file system, and the obtained file paths are determined as the second candidate file path.

[0062] (3) For the file path newly added by the Android media database, all file paths under the file path are obtained from the local file system, and the obtained file paths are determined as the third candidate file path.

[0063] (4) The set of the first candidate file path, the second candidate file path and the third candidate file path is determined as the candidate file path set.

[0064] S203, comparing the file path currently existing in the service provider multimedia database with the candidate file path set to determine the target file path set newly added or deleted in the local, and generating the final scanning task based on the target file path set.

[0065] In a specific implementation, the existing file paths in the service provider multimedia database can be compared with the candidate file path set to determine which paths in the candidate file path set are target file paths that are newly added locally and which paths in the existing file paths in the service provider multimedia database are target file paths that are deleted locally.

[0066] The method provided in this embodiment can, when the scanning request carries identification information, find a processing strategy corresponding to the identification information from a pre-set correspondence between identification information and processing strategies, and then determine a candidate file path set corresponding to the scanning request based on the candidate file path set in the processing strategy, so as to compare the existing file paths in the service provider multimedia database with the candidate file path set, determine a target file path set that is newly added or deleted locally, and generate the final scanning task based on the target file path set. In this way, multiple final scanning tasks can be processed in parallel based on multiple scanning threads executed in parallel, the scanning efficiency can be improved, and the scanning time can be reduced.

[0067] Optionally, in a possible implementation of the present disclosure, the method further includes:

[0068] The steps of determining the target file path set that is newly added or deleted locally and generating the final scanning task based on the target file path set are executed in parallel based on multiple processing threads.

[0069] It should be noted that, as described above, when the file paths that are newly added or deleted locally are determined, the existing file paths in the service provider multimedia database need to be compared with the file paths in the candidate file path set one by one to determine which paths in the candidate file path set are target file paths that are newly added locally and which paths in the existing file paths in the service provider multimedia database are target file paths that are deleted locally.

[0070] In this embodiment, when the comparison is performed to determine the target file path set that is newly added or deleted locally and generate the final scanning task based on the target file path set, this process can be executed in parallel based on multiple processing threads. In this way, the efficiency can be further improved, and the time can be shortened.

[0071] Optionally, in a possible implementation of the present disclosure, the processing strategy further includes a grouping strategy, and after the candidate file path set corresponding to the scanning request is determined, the method further includes:

[0072] divide the candidate file path set into at least one group based on the grouping policy;

[0073] For each group, generate an intermediate scanning task based on the group;

[0074] The step of executing in parallel using multiple processing threads to determine the target file path set that is newly added or deleted locally and generate the final scanning task based on the target file path set comprises:

[0075] Each intermediate scanning task is processed in parallel using multiple processing threads; wherein the process of processing the intermediate scanning task comprises comparing the file paths that currently exist in the service provider multimedia database with the group carried by the intermediate scanning task, determining the target file path set that is newly added or deleted locally, and generating the final scanning task based on the target file path set.

[0076] Specifically, the grouping policy is set according to actual needs, and in this embodiment, the grouping policy is not limited.

[0077] For example, in an embodiment, when the identification information of the scanning request is X or Z, the corresponding grouping policy is to divide the candidate file path set into one group; when the identification information of the scanning request is Y and the candidate file path determination policy is the case given in the second example above, the corresponding grouping policy can be to divide the first candidate file path into one group, divide the second candidate file path into one group, divide the file path corresponding to the video in the third candidate file path into one group, and divide the file path corresponding to the picture in the third candidate file path into one group, i.e., divide the candidate file set into four groups according to the above method.

[0078] In a specific implementation, for each group, the group can be encapsulated as an intermediate scanning task. For specific implementation principles of encapsulation, reference can be made to the description in the foregoing embodiments, which will not be described here again.

[0079] In addition, in this embodiment, when the step of executing in parallel using multiple processing threads to determine the target file path set that is newly added or deleted locally and generate the final scanning task based on the target file path set is performed, each intermediate scanning task can be processed in parallel using multiple processing threads. Wherein the process of processing the intermediate scanning task comprises comparing the file paths that currently exist in the service provider multimedia database with the group carried by the intermediate scanning task, determining the target file path set that is newly added or deleted locally, and generating the final scanning task based on the target file path set.

[0080] For example, in an embodiment, the candidate file path set contains 50 file paths, and in this embodiment, the 50 file paths can be divided into two groups to obtain two intermediate scanning tasks, and then the two intermediate scanning tasks are processed in parallel. In this way, frequent scheduling processes can be avoided, and scheduling pressure can be reduced.

[0081] The method provided in this embodiment divides the candidate file path set into at least one group, and then generates an intermediate scanning task based on each group. In this way, multiple processing threads can be used to process the intermediate scanning tasks in parallel, which not only improves efficiency but also reduces scheduling pressure.

[0082] It should be noted that in an embodiment, when processing a scanning task (which can include a final scanning task and an intermediate scanning task), the priority of the scanning task can be determined first, and the scanning tasks are processed in parallel based on the order from high to low according to the priority.

[0083] When implemented, the priority of the scanning task can be determined based on the time when the scanning task is generated, the size of the file corresponding to the file path carried by the scanning task, etc. In this embodiment, it is not limited, for example, in an embodiment, when the time when the scanning task is generated is earlier, a higher priority can be assigned to the scanning task.

[0084] The method provided in this embodiment determines the priority of each scanning task before processing the scanning task, and then processes the scanning task based on the priority when processing the scanning task. In this way, certain tasks can be executed in priority.

[0094] For example, in an embodiment, the number of processing threads is 2, that is, two intermediate scan tasks can be processed simultaneously.

[0095] S307, process each final scan task in parallel based on multiple scan threads, obtain the scan result corresponding to each final scan task, and insert the scan result into the service provider multimedia database.
