Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions in the present application are further described in detail by the following examples with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.

Referring to fig. 1, the media file scanning method provided in the embodiment of the present application is applicable to a scenario in which when an external device (or a storage peripheral) is mounted to a terminal device, the terminal device performs media file scanning on the external device. The method may be performed by a media file scanning device in the terminal device, which may be implemented in particular by means of software and/or hardware. The terminal device may be an in-vehicle terminal or an android television device, for example. The external device can be pluggable storage devices such as a USB flash disk and a mobile hard disk. The media files may include audio files, video files, or image files.

As shown in fig. 1, the media file scanning method provided in the embodiment of the present application is applied to a terminal device, and the method specifically may include the following contents:

s101, when receiving the mounting broadcast of the first external device, determining whether the storage content in the first external device is modified.

When the first external device is mounted on the terminal device, a system of the terminal device can send out a mounting broadcast, a broadcast receiver for scanning static registration receives the mounting broadcast, and a scanning process with a message circulation mechanism is started to start scanning. Before scanning, it is necessary to determine whether there is a modification to the stored content in the first external device. If yes, the following S102 is executed; if not, the file information of all the media files in the first external equipment is directly obtained from the database without traversing and scanning all the media files in the first external equipment, and the file information is returned to the media application for use. Particularly, when the first external device is not used for the first time, detailed information of all media files in the first external device can be rapidly displayed in the media application, and millisecond-level display is achieved. The detailed information of the media file may include a file path, a title, an author, an album, and the like of the media file.

Optionally, determining whether the stored content in the first external device is modified may include: and filtering the fragment files in the first external equipment and determining whether the filtered storage content in the first external equipment is modified or not.

Wherein, the fragment file can be determined by the following way:

1) And determining the file with the file size smaller than the preset value as a fragment file.

Fragmented files are typically relatively small, typically below 100KB, and files with file sizes below 100KB may be determined to be fragmented files.

2) Some read-only files, hidden files or system files, etc.

By filtering the fragmented files, scanning of the fragmented files is reduced, which may reduce the waiting time of the user.

S102, determining the interested folder of the user in the modified folder.

The modified folder refers to a folder where the modified media file is located, and the interested folder refers to a folder where the user's interested media file is located. The media files that are frequently viewed and played by the user may be considered to be media files of interest to the user.

Upon determining that there is a modification to the stored content in the first external device, the modified folders may be analyzed to determine which modified folders may be the folders of interest to the user. In an alternative embodiment, the user's folder of interest may be determined in conjunction with the user's historical travel log. For example, folders that are frequently browsed/opened may be considered folders of interest to the user.

S103, analyzing the media files under the interested folder preferentially, analyzing the media files under the other folders except the interested folder in the modified folder, and storing the analyzed file information into a database for use by a media program.

After determining the folder of interest of the user, the media files under the folder of interest of the user can be preferentially analyzed, and the analyzed file information is stored in the database. Further, a data change callback may also be sent to the media application. After the media application receives the data change callback, the data is obtained from the database and displayed, so that the media application can obtain and display the file information of part of the media files in advance before the media scanning is finished, namely, the detailed information of the media files of interest of the user is displayed quickly, the user can see the files frequently used by the user instantly, and the waiting time of the user is shortened. Further, the background continues to analyze the media files under the rest folders except the interested folder in the modified folder, and stores the analyzed file information into the database. Further, the presentation content in the media application is refreshed with the portion of the changed data, i.e., the detailed information of the media files under the remaining folders is also presented in the media application.

In data presentation, media files may be presented in a media application in the form of a file list. When the number of the media files in the file list is large, a user needs to repeatedly slide the screen to find the media files required by the user, in order to facilitate the user to quickly locate the target media files, the media files can be displayed in the form of folders, namely, the file scanning service screens out the media files corresponding to the media application types based on the media application types opened by the user, classifies and unifies the media files into the corresponding folders according to the file path information, and recalls the classified and unified results to the media application, so that the media application displays the media files in the form of folders, namely, the first page in the media application only displays the folders in which the media files are located, and after the user clicks a certain folder, the media files under the folders are displayed. In this way, since the media files are classified according to the folders, compared with the file list, the number of the folders displayed in the media application is relatively small, so that a user can easily locate a target folder, and further locate the target media file from the target folder, thereby being convenient for the user to operate.

Optionally, in order to further shorten waiting time of the user, the scanning service in the terminal device may be matched with the media application to obtain a media application type opened by the user, and according to the media application type opened by the user, the media application type is classified into video, music, pictures, and the like, media files corresponding to the media application type opened by the user under the folder of interest are preferentially analyzed, and then media files corresponding to the media application types opened by the user under other files except the folder of interest in the modified folder are analyzed. For example, if the media application type opened by the user is a music player, the audio files under the folder of interest of the user are preferentially parsed, and then the audio files under the rest folders except the folder of interest are parsed.

According to the media file scanning method provided by the embodiment of the application, when the mounted broadcast of the first external device is received, if the storage content of the first external device is confirmed to be modified, the interested folder of a user in the modified folder is confirmed, media files under the interested folder are analyzed preferentially, then the media files under the other folders except the interested folder in the modified folder are analyzed, and the analyzed file information is stored in the database, namely, when the first external device is scanned, only the media files in the modified folder are analyzed, and repeated analysis of all the media files is not needed, so that the media application can rapidly display detailed information of the media files in the first external device, and the waiting time of the user is shortened; in addition, media files in the folder of interest of the user are preferentially analyzed in the scanning process, so that the media application can acquire and display file information of part of the media files in advance before the media scanning is finished, namely the media application can rapidly display detailed information of the media files under the folder of interest of the user, the waiting time of the user is further shortened, and the user experience is improved.

In practical applications, the first external device may be an existing external device (i.e. an external device that has been mounted on the terminal device) or may be a new external device (i.e. an external device that has not been mounted on the terminal device), and for this case, based on the foregoing embodiment, optionally, as shown in fig. 2, determining whether the storage content in the first external device has been modified in S101 may include:

s201, acquiring a device identification code of the first external device.

S202, matching the device identification code with the first data set stored currently.

The first data set stores device identification codes of a plurality of second external devices mounted on the terminal device in a specified time period.

The above specified period of time may be the past several days, the past one month, the past several months, or the like, and may be set based on actual demands.

Matching the device identification code of the first external device with the first data set, and if so, executing the following S203; if the content is not matched, the first external device is considered to be a new external device (i.e. the first time of being mounted on the terminal device), in some cases, the stored content in the new first external device may be directly copied to the stored content in the existing external device, in other cases, the stored content in the new first external device may be the stored content after the stored content in the existing external device is modified, and further judgment is needed in combination with the following processes of S204-S207.

S203, determining whether the storage content in the first external device is modified according to the modification time and/or the space size of each folder in the first external device.

The terminal device can store the related information of the second external device mounted on the terminal device in a specified time period, when the first external device is determined to be the mounted external device, the space size and/or the modification time of each folder of the first external device during the last mounting can be obtained from the database, and the space size of each folder scanned by the first external device during the current mounting is compared with the space size of each folder during the last mounting, so that whether the storage content in the first external device is modified or not is determined. For example, if the space size of each folder is not changed when the first external device is mounted twice, the storage content of the first external device can be considered to be unmodified, and if the space sizes of each folder are different when the first external device is mounted twice, the storage content of the first external device can be considered to be modified. Of course, the modification time of each folder scanned by the first external device during the current mounting can be compared with the modification time of each folder during the last mounting, so as to determine whether the storage content in the first external device is modified. For example, when the modification time of each folder is inconsistent during the twice mounting of the first external device, it is determined that the storage content in the first external device is modified, otherwise, it is determined that the storage content of the first external device is not modified.

S204, acquiring identification information of all folders and all media files under the condition that the root directory of the first external device is up to a preset hierarchical directory.

The preset hierarchical directory may be set in combination with an actual requirement, for example, may be a secondary directory, a tertiary directory, or even more hierarchical directories.

The identification information may be a folder name or a media file name. Specifically, traversing the folders and the media files in the first external device from the root directory, if the files are media files, directly acquiring the names of the media files, if the files are target folders, acquiring the names of the target folders and the directory levels to which the target folders belong, acquiring the names of the sub-media files, the directory levels to which the sub-media files belong, the names of the sub-folders and the directory levels to which the sub-folders belong in the target folders according to a preset level directory, and combining the names of the target folders, the directory levels to which the target folders belong, the names of the sub-media files, the directory levels to which the sub-media files belong, the names of the sub-folders and the directory levels to which the sub-folders belong to generate the target names of the target folders.

Taking the preset hierarchical directory as a secondary directory as an example, assuming that the root directory of the first external device includes a folder a, a folder B and a folder C, where the folder a includes a folder D and a folder E, and the folder B does not include any file, the target name AA of the folder a is 1a+2d+2e (where 1 and 2 respectively represent the current primary directory or the secondary directory); target name bb=1b of folder B; the target name cc=c of file C.

And S205, splicing the identification information according to a preset rule to obtain a spliced character string.

Illustratively, the object names of the folder a, the folder B, and the file C are spliced to obtain the spliced character string "1a+2d+2e+1b+c".

S206, encrypting the spliced character string to obtain a first file identification encryption value corresponding to the first external device.

Alternatively, the encryption Algorithm may be a Message Digest Algorithm (md5) Algorithm, a hash Algorithm, or other encryption Algorithm.

After the spliced character string is obtained, the spliced character string is encrypted by adopting a preset encryption algorithm, so that a first file identification encrypted value corresponding to the first external equipment is obtained.

S207, determining whether the stored content in the first external device is modified according to the matching result of the first file identification encryption value and the second data set stored currently.

And the second data set stores second file identification encryption values corresponding to a plurality of second external devices mounted on the terminal device in a specified time period.

After a first file identification encryption value corresponding to the first external equipment is obtained, matching the first file identification encryption value with a second data set stored currently, and if the first file identification encryption value is matched with the second data set, determining that the storage content in the first external equipment is not modified; if the first external equipment is not matched with the first external equipment, the stored content in the first external equipment is confirmed to be modified.

In this embodiment, when the device identifier of the first external device is matched in the first data set currently stored in the terminal device, whether the storage content in the first external device is modified is determined based on the modification time of each folder in the first external device and/or the size of the space occupied by each folder; when the device identification code of the first external device is not matched in the first data set currently stored in the terminal device, whether the stored content in the first external device is modified or not is further determined by processing the identification information of all folders and all media files under the condition that the root directory of the first external device is up to the preset hierarchical directory, and different judging means are adopted aiming at different use conditions of the first external device, so that the accuracy of a judging result can be ensured.

In one embodiment, optionally, as shown in fig. 3, the above S102 may include the following:

s301, acquiring played media files in a plurality of second external devices mounted on the terminal device in a specified time period.

Wherein the specified period of time may be the last days, the last month, the last months, or the like, and may be set based on actual demands.

By analyzing the historical play records of the user, the played media files in the second external device and the information such as the play frequency, the play time and the like of the user aiming at each played media file can be obtained.

S302, determining the retention rate of the user for each played media file.

And determining the retention rate of the user for each played media file based on the obtained information such as the playing frequency and/or the playing time of the user for each played media file. For example, if the playing frequency of a certain played media file is higher, the higher the retention rate of the played media file is indicated to the user; conversely, if the playing frequency of a certain played media file is lower, the lower the retention rate of the played media file for the user is indicated.

As an alternative embodiment, the above S302 may be implemented by:

acquiring average playing time of a user for each played media file in a specified time period;

and determining the retention rate of the user for each played media file based on the average playing time of each played media file and the file duration of each played media file.

Specifically, the playing times of the user for each played media file and the playing time of each playing time in a specified time period are obtained, and the average playing time of the user for the played media file in the specified time period is determined by utilizing the playing times of the played media file and the playing time of each playing time; further, a ratio between the average playing time of the played media file and the file duration of the played media file is determined, and the ratio is determined as the retention rate of the user for the played media file.

S303, determining the media files of interest of the user according to the retention rate of each played media file.

After obtaining the retention rate of each played media file, sorting the played media files according to the order of the retention rate from high to low, and determining the interested media files of the user based on the sorting result. For example, the first 10 played media files in the ranking result are determined to be media files of interest to the user.

Of course, the played media file with the retention rate greater than the preset threshold may also be determined as the media file of interest of the user, which is not limited in the embodiment of the present application.

S304, acquiring a folder identifier of a folder in which the media file of interest is located.

S305, determining the folder corresponding to the folder identification in the modified folders as the interested folder of the user.
