When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the disclosure, as detailed in the appended claims.

The disclosure provides a multimedia file scanning method, a multimedia file scanning device and terminal equipment, which are used for improving the scanning efficiency of multimedia files and reducing the scanning time.

The method and the device for scanning the multimedia file can be applied to terminal equipment. For example, it can be applied to a mobile phone or the like.

Several specific examples are given below to illustrate the technical solution of the present disclosure in detail. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.

Fig. 1 is a flow chart illustrating a multimedia file scanning method according to an exemplary embodiment of the present disclosure. Referring to fig. 1, the method provided in this embodiment is applied to a terminal device, and the method may include:

s101, when a multimedia file scanning request aiming at a service provider multimedia database on the equipment is received, determining a target file path set required to be scanned by the scanning request.

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

In another embodiment, the multimedia file scanning request is a multimedia file scanning request for an android media database on the device generated when a file creation notification reported by a third-party application is detected.

It should be noted that, when detecting a file creation operation, the third-party application reports a file creation notification to the terminal system, and 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, so as to scan a multimedia file based on the multimedia file scanning request for the android media database on the device, and update the android media database.

Further, the terminal system determines the multimedia file scanning request for the android media database on the device as a multimedia scanning request for a service provider multimedia database on the device, so as to scan the multimedia file based on the multimedia scanning request and update the service provider multimedia database.

Further, in yet another embodiment, the multimedia file scan request may be generated upon detecting that an album application on the device creates a file.

Specifically, the state of the album application may be monitored, and then when it is monitored that the album application creates a file (for example, a user edits an original picture to generate a new picture), a multimedia file scanning request may be generated.

In addition, the set of target file paths are file paths that have been added or deleted by the local file system as compared to the service provider multimedia database. The specific implementation principle of determining the target file path set required to be scanned by the scan request will be described in detail in the following embodiments, and will not be described herein again.

S102, generating a plurality of final scanning tasks according to the target file path set; and each final scanning task is used for indicating to scan the file under one target file path in the target file path set.

Specifically, each target file path may be packaged into a final scan job, where the final scan job carries the target file path and is used to instruct to scan a file under the target file path. For the specific implementation principle and implementation process of the package, reference may be made to the description in the related art, and details are not described herein.

It should be noted that, when a final scan task is generated based on a target file path, if a file under the target file path is a newly added file, a type of the final scan task is generated as the newly added final scan task, and if a file under the target file path is a deleted file, a type of the final scan task is generated as the deleted final scan task.

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

For example, in one embodiment, the number of scan threads is 4, i.e., 4 final scan tasks can be processed simultaneously at one time.

In addition, when the scanning result is inserted into the service provider multimedia database, the scanning result can be inserted into the service provider multimedia database in a batch processing mode.

Optionally, in a possible implementation manner, if the file paths carried by the several final scanning tasks are the same, when the final scanning task is processed, the several final scanning tasks may be merged, that is, only one of the final scanning tasks is reserved. Therefore, resources can be saved, the scanning efficiency is further improved, and the scanning time is reduced.

In the method provided by this embodiment, when a multimedia file scanning request for a multimedia database of a service provider on the device is received, a target file path set that needs to be scanned by the scanning request is determined, and then a plurality of final scanning tasks are generated according to the target file path set, so that each final scanning task is processed in parallel based on a plurality of scanning threads, a scanning result corresponding to each final scanning task is obtained, and the scanning result is inserted into the multimedia database of the service provider. And each final scanning task is used for indicating to scan the file under one target file path in the target file path set. Therefore, the final scanning task is processed in parallel through multiple scanning threads, the scanning efficiency can be improved, and the scanning time can be reduced.

FIG. 2 is a flow chart illustrating another method of multimedia file scanning according to an exemplary embodiment of the present disclosure. Referring to fig. 2, in the method provided in this embodiment, on the basis of the foregoing embodiment, the scan request carries identification information; the determining a target file path set that needs to be scanned by the scanning request, and generating a plurality of final scanning tasks according to the target file path set may include:

s201, searching a processing strategy corresponding to the identification information from a preset corresponding relation between the identification information and the processing strategy according to the identification information; wherein the processing policy comprises a candidate file path set determination policy.

Specifically, in this embodiment, the scanning request carries identification information, which is used to identify a trigger scenario of the scanning request. For example, when the scan request is generated when it is detected that the album application on the present device is started or returned to the foreground, the identification information carried by the scan request may be Y. When the scanning request is a multimedia file scanning request for an android media database on the device, which is generated when a file creation notification reported by a third-party application is detected, the identification information carried by the scanning request may be Z. When the scan request is generated when detecting that the album application on the device creates a file, the identification information carried by the scan request may be X.

It should be noted that, when the scan request is a multimedia file scan request for an android media database on the device generated when a file creation notification reported by a third-party application is detected, or when the scan request is a scan request generated when an album application on the device is detected to create a file, the scan request also carries a file path (the file path may be a file path corresponding to a newly created file).

In addition, the preset correspondence between the identification information and the processing policy is set according to actual needs, and in this embodiment, specific contents thereof are not limited.

For example, in an embodiment, when the identification information is Z or X, the candidate file path set determination policy corresponding to the identification information may be: and acquiring all file paths under the file path carried by the scanning request from a local file system, and determining the acquired file paths as a candidate file path set.

For another example, in another embodiment, when the identification information is Y, the candidate file path set determination policy corresponding to the identification information may be: and determining all file paths in the local file system as a candidate file path set.

Of course, in another embodiment, when the identification information is Y, the candidate file path set determination policy corresponding to the identification information may be: determining all file paths (the file path corresponding to the third-party application refers to a file path for storing data generated by the third-party application) corresponding to a specified third-party application (the specified third-party application is set according to actual needs, and can be QQ, WeChat and the like, for example) existing in the local file system and all file paths under the specified file path acquired from the local file system as a candidate file path set; the specified file path can be a current existing file path of a multimedia database of a service provider and/or a newly added file path of an android media database.

S202, determining a strategy based on the candidate file path set, and determining the candidate file path set corresponding to the scanning request.

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

(1) and judging whether a storage space (used for storing data generated by the third-party application) corresponding to the third-party application exists in the local file system or not aiming at any specified third-party application, and if so, determining all file paths in the local file system under the storage space as first candidate file paths.

(2) And aiming at any current existing file path of the multimedia database of the service provider, acquiring all file paths under the file path from a local file system, and determining the acquired file paths as second candidate file paths.

(3) And aiming at the newly added file path of the android media database, acquiring all file paths under the file path from a local file system, and determining the acquired file path as a third candidate file path.

(4) Determining a set of first, second, and third candidate file paths as a set of candidate file paths.

S203, comparing the current existing file path in the multimedia database of the service provider with the candidate file path set, determining a locally added or deleted target file path set, and generating the final scanning task based on the target file path set.

In a specific implementation, the file path that currently exists in the multimedia database of the service provider may be compared with the candidate file path set to determine which paths in the candidate file path set are locally added target file paths, and to determine which paths in the file paths that currently exist in the multimedia database of the service provider are locally deleted target file paths.

In the method provided by this embodiment, when a scanning request carries identification information, a processing policy corresponding to the identification information is searched from a preset correspondence between the identification information and the processing policy according to the identification information, and then a policy is determined based on the candidate file path set in the processing policy, and a candidate file path set corresponding to the scanning request is determined, so that a file path that currently exists in the service provider multimedia database is compared with the candidate file path set, a locally added or deleted target file path set is determined, and the final scanning task is generated based on the target file path set. Therefore, a plurality of final scanning tasks can be processed in parallel subsequently based on a plurality of parallel execution scanning threads, the scanning efficiency can be improved, and the scanning time can be reduced.

Optionally, in a possible implementation manner of the present disclosure, the determining a locally added or deleted target file path set, and generating the final scanning task based on the target file path set includes:

and executing and determining a locally added or deleted target file path set in parallel based on a plurality of processing threads, and generating the final scanning task based on the target file path set.

It should be noted that, referring to the foregoing description, when determining a locally added or deleted file path, it is necessary to compare a file path currently existing in the multimedia database of the service provider with file paths in the candidate file path set one by one to determine which paths are locally added target file paths in the candidate file path set, and determine which paths are locally deleted target file paths in currently existing file paths in the multimedia data path on the service.

In this embodiment, when performing one-to-one comparison, determining a locally added or deleted target file path set, and generating the final scanning task based on the target file path set, the process may be executed in parallel based on multiple processing threads. Thus, the efficiency can be further improved and the time can be shortened.

Optionally, in a possible implementation manner of the present disclosure, the processing policy further includes a grouping policy; after determining the candidate file path set corresponding to the scan request, the method further includes:

dividing the set of candidate file paths into at least one group based on the grouping policy;

for each packet, generating an intermediate scanning task based on the packet;

the step of determining a locally added or deleted target file path set by adopting a plurality of processing threads to execute in parallel and generating the final scanning task based on the target file path set comprises the following steps:

processing each intermediate scanning task in parallel by adopting a plurality of processing threads; the process of processing the intermediate scanning task comprises the steps of comparing the current existing file path in the service provider multimedia database with the packet carried by the intermediate scanning task, determining a locally added or deleted target file path set, and generating the final scanning task based on the target file path set.

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

For example, in an embodiment, when the identification information of the scan request is X or Z, the corresponding packet policy is: dividing the candidate file path set into a group; when the identification information of the scan request is Y and the candidate file path determination policy is the case given in the second example described above, the corresponding grouping policy may be: the first candidate file path is divided into a group, the second candidate file path is divided into a group, the file path corresponding to the video in the third candidate file path is divided into a group, the file path corresponding to the picture in the third candidate file path is divided into a group, namely, the candidate file set is divided into four groups according to the method.

In particular implementations, for each packet, the packet may be encapsulated as an intermediate scanning task. For the specific implementation principle of the package, reference may be made to the description in the foregoing embodiments, and details are not described here.

In addition, in this embodiment, when the step of determining the locally added or deleted target file path set is executed in parallel by using a plurality of processing threads, and the final scanning task is generated based on the target file path set, each intermediate scanning task may be processed in parallel by using a plurality of processing threads. The process of processing the intermediate scanning task comprises the steps of comparing the current existing file path in the service provider multimedia database with the packet carried by the intermediate scanning task, determining a locally added or deleted target file path set, and generating the final scanning task based on the target file path set.

For example, in an embodiment, the candidate file path set includes 50 file paths in total, and in this embodiment, the 50 file paths may be divided into two groups to obtain two intermediate scanning tasks, and then the two intermediate scanning tasks are processed in parallel. Thus, frequent scheduling procedures can be avoided, and scheduling pressure can be reduced.

In the method provided by this embodiment, the candidate file path set is divided into at least one group, and then for each group, an intermediate scanning task is generated based on the group. Therefore, the intermediate scanning tasks can be processed in parallel by adopting a plurality of processing threads, so that the efficiency can be improved, and the scheduling pressure can be reduced.

It should be noted that, in an embodiment, in processing the scanning tasks (which may include the final scanning task and the intermediate scanning task), the priority of the scanning tasks may be determined first, and the scanning tasks are processed in parallel according to the order from high to low in the priority.

In a specific implementation, the priority of the scanning task may be determined based on the generation time of the scanning task, the size of the file corresponding to the file path carried by the scanning task, and the like.

In the method provided by this embodiment, before processing a scan task, the priority of each scan task is determined, and when processing the scan task, the scan task is processed based on the priority. In this way, certain tasks may be guaranteed to execute preferentially.
