The disclosure provides a multimedia file scanning method, a device and terminal equipment, so as to improve the scanning efficiency of multimedia files and reduce the scanning time.
The multimedia file scanning method and device provided by the disclosure can be applied to terminal equipment. For example, it can be applied to mobile phones and the like.
Several specific examples are given below to illustrate the technical aspects of the present disclosure in detail. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.
Fig. 1 is a flowchart of 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 server multimedia database on the equipment is received, determining a target file path set which needs to be scanned by the scanning request.
It should be noted that, in an embodiment, the multimedia file scan 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 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.
It should be noted that when the third party application detects the file creation operation, a file creation notification is reported 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 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.
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 server multimedia database on the device, so as to scan the multimedia file based on the multimedia scanning request and update the server multimedia database.
Further, in yet another embodiment, the multimedia file scan request may be generated upon detecting that an album application on the present device creates a file.
Specifically, the state of the album application may be monitored, and when the album application creates a file (for example, a user edits an original picture to generate a new picture) is monitored, a multimedia file scanning request is generated.
In addition, the target file path set is a file path that is added or deleted by the local file system compared to the server multimedia database. The specific implementation principles for determining the target file path set to be scanned by the scan request will be described in detail in the following embodiments, which are not described herein.
S102, generating a plurality of final scanning tasks according to the target file path set, wherein each final scanning task is used for indicating to scan a file under one target file path in the target file path set.
Specifically, for each target file path, it may be wrapped into a final scan task that carries the target file path for indicating to scan the files under the target file path. The specific implementation principle and implementation process of the package may refer to descriptions in the related art, and are not repeated herein.
When a final scan task is generated based on a target file path, if the file under the target file path is a newly added file, a final scan task with a new type is generated, and if the file under the target file path is a deleted file, a final scan task with a deleted type is generated.
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 server 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 scan result is inserted into the service provider multimedia database, the scan result may be inserted into the service provider multimedia database in a batch process.
Optionally, in a possible implementation manner, if the file paths carried by the several final scan tasks are the same, when the final scan tasks are processed, the several final scan tasks may be combined, that is, only one of the final scan tasks may be reserved. Therefore, resources can be saved, the scanning efficiency is further improved, and the scanning time is reduced.
According to the method provided by the embodiment, when a multimedia file scanning request aiming at a service provider multimedia database on the equipment is received, a target file path set which 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 to obtain a scanning result corresponding to each final scanning task, and the scanning result is inserted into the service provider multimedia database. 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, so that the scanning efficiency can be improved, and the scanning time can be reduced.
Fig. 2 is a flowchart of another multimedia file scanning method according to an exemplary embodiment of the present disclosure. Referring to fig. 2, based on the foregoing embodiment, the method provided in this embodiment, where the scan request carries identification information, and the determining a target file path set to be scanned by the scan request and generating a plurality of final scan tasks according to the target file path set may include:
S201, searching a processing strategy corresponding to the identification information from the corresponding relation between the preset identification information and the processing strategy according to the identification information, wherein the processing strategy comprises a candidate file path set determining strategy.
Specifically, in this embodiment, the scan request carries identification information, which is used to identify the trigger scenario of the scan request. For example, when a scan request is generated when it is detected that an album application on the device is started or returns to the foreground, the identification information carried by the scan request may be Y. When the scanning request is a multimedia file scanning request aiming at an android media database on the device, which is generated when the file creation notification reported by the third party application is detected, the identification information carried by the scanning request can be Z. When a scan request is generated when it is detected that an 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 present device, which is 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 creation file on the present device is detected, the scan request further carries a file path (the file path may be a file path corresponding to a newly created file).
In addition, the correspondence between the preset identification information and the processing policy is set according to the actual needs, and in this embodiment, the specific content is not limited.
For example, in an embodiment, when the identification information is Z or X, the corresponding candidate file path set determining policy may be that all file paths under the file path carried by the scan request are obtained from the local file system, and the obtained file paths are determined as the candidate file path set.
For another example, when the identification information is Y, the corresponding candidate file path set determining policy may be to determine all file paths in the local file system as candidate file path sets.
Of course, in still another embodiment, when the identification information is Y, the corresponding candidate file path set determining policy may be to determine all file paths (file paths corresponding to the third party application refer to file paths for storing data generated by the third party application) corresponding to specified third party applications (the specified third party application may be set according to actual needs, for example) existing in the local file system and all file paths under the specified file paths acquired from the local file system as the candidate file path set, where the specified file paths may be file paths currently existing in the server multimedia database and/or file paths newly added in the android media database.
S202, determining a candidate file path set corresponding to the scanning request based on the candidate file path set determination strategy.
For example, in one embodiment, the identification information carried by the scan information is Y, and at this time, based on the candidate file path determining policy given in the second example above, the candidate file path set corresponding to the scan request may be determined according to the following method:
(1) And judging whether a storage space corresponding to the third party application exists in the local file system (used for storing data generated by the third party application) aiming at any appointed 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 for any file path currently existing in the service provider multimedia database, acquiring all file paths under the file path from a local file system, and determining the acquired file path as a second candidate file path.
(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) And determining a set of the first candidate file path, the second candidate file path and the third candidate file path as a candidate file path set.
S203, comparing the file paths existing in the server multimedia database with the candidate file path sets, determining a target file path set which is newly added or deleted locally, and generating the final scanning task based on the target file path set.
In particular, the file paths currently existing in the server multimedia database can 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 determine which paths in the file paths currently existing in the server multimedia database are locally deleted target file paths.
According to the method provided by the embodiment, when the scanning request carries the identification information, the processing strategy corresponding to the identification information is searched from the corresponding relation between the preset identification information and the processing strategy according to the identification information, and then the candidate file path set corresponding to the scanning request is determined based on the candidate file path set determining strategy in the processing strategy, so that the file path which is currently existing in the server multimedia database is compared with the candidate file path set, a target file path set which is newly added or deleted locally 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 based on a plurality of scanning threads which are executed in parallel, so that 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 scan task based on the target file path set includes:
and executing the step of determining a local newly added or deleted target file path set based on a plurality of processing threads in parallel, 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 file path that is newly added or deleted locally, it is necessary to compare a file path that is currently existing in the server multimedia database with a file path in 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 determine which paths in the file path that is currently existing in the multimedia data path on the server are target file paths that are deleted locally.
In this embodiment, when a comparison is performed to determine a locally added or deleted target file path set, and the final scan task is generated based on the target file path set, this 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, and after determining the candidate file path set corresponding to the scan request, the method further includes:
Dividing the candidate file path set into at least one group based on the grouping policy;
for each packet, generating an intermediate scan task based on the packet;
The step of using a plurality of processing threads to execute and determine a local newly added or deleted target file path set in parallel and generating the final scanning task based on the target file path set comprises the following steps:
And processing each intermediate scanning task in parallel by adopting a plurality of processing threads, wherein the process of processing the intermediate scanning task comprises the steps of comparing a file path existing in the service provider multimedia database currently with a packet carried by the intermediate scanning task, determining a target file path set which is newly added or deleted locally, 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 one embodiment, when the identification information of the scan request is X or Z, the corresponding grouping policy is that the candidate file path set is divided into one group, and when the identification information of the scan request is Y and the candidate file path determining policy is given in the second example described above, the corresponding grouping policy may be that the first candidate file path is divided into one group, the second candidate file path is divided into one group, the file path corresponding to the video in the third candidate file path is divided into one group, and the file path corresponding to the picture in the third candidate file path is divided into one group, that is, the candidate file set is divided into four groups according to the above method.
In particular, for each packet, the packet may be encapsulated as an intermediate scan task. The specific implementation principles of the package may be referred to the description of the foregoing embodiments, and will not be repeated here.
In addition, in this embodiment, when a step of determining a locally added or deleted target file path set and generating the final scan task based on the target file path set is performed in parallel by using a plurality of processing threads, each of the intermediate scan tasks 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 a file path existing in the server multimedia database currently with a group carried by the intermediate scanning task, determining a target file path set which is newly added or deleted locally, 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, so as to obtain two intermediate scanning tasks, and further process the two intermediate scanning tasks in parallel. In this way, frequent scheduling processes can be avoided and scheduling pressure can be reduced.
The method provided by the embodiment divides the candidate file path set into at least one group, and further generates an intermediate scanning task based on each group. Thus, a plurality of processing threads can be adopted to process the intermediate scanning task in parallel, so that not only can the efficiency be improved, but also the dispatching pressure can be reduced.
In one embodiment, in processing the scan task (including the final scan task and the intermediate scan task), the priority of the scan task may be determined first, and the scan task may be processed in parallel based on the order of the priority from high to low.
In particular, when the method is implemented, 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, which is not limited in this embodiment, for example, in an embodiment, a higher priority may be assigned to the scanning task when the generation time of the scanning task is earlier.
According to the method provided by the embodiment, before the scanning tasks are processed, the priority of each scanning task is determined, and then when the scanning tasks are processed, the scanning tasks are processed based on the priority. In this way, priority execution of certain tasks may be guaranteed.
