In summary, the embodiment of the present application provides a file updating method, in which a multimedia client in the method can obtain completion metadata of a multimedia file from a server, and update the multimedia file based on the completion metadata. Therefore, the updated metadata of the multimedia file can be ensured to be perfect, and the playing effect of the multimedia file played by the multimedia client is better. In addition, the file updating method provided by the embodiment of the application realizes the perfection of the metadata of the multimedia file through the interaction between the multimedia client and the server, and does not need the manual completion of data by a user, so that the efficiency of perfecting the metadata is higher, and the updating efficiency of the multimedia file is further improved.
Fig. 4 is a flowchart of another file updating method provided in an embodiment of the present application. The method can be applied to the application scenario shown in fig. 1. Referring to fig. 4, the method may include:
step 301, the multimedia client obtains initial metadata of the multimedia file.
In the embodiment of the present application, a multimedia client may be installed in the terminal, and the multimedia client may be used to play a multimedia file. The terminal may have a plurality of multimedia files stored therein in advance. The multimedia client may parse a multimedia file of the plurality of multimedia files to obtain initial metadata of the multimedia file. The multimedia file may be an audio file or a video file.
Optionally, the multimedia file is an audio file, and the initial metadata of the multimedia file may include: audio name, lyrics, author, album name, and album art. The multimedia file is a video file, and the initial metadata of the multimedia file may include: at least one of a video name and a subtitle.
As an alternative implementation manner, the multimedia client may respond to a play instruction for the multimedia file, and parse the multimedia file to obtain the initial metadata of the multimedia file. The playing instruction for the multimedia file may be generated by user triggering or may be automatically generated by the multimedia client.
Optionally, the application interface of the multimedia client displays a file list of a plurality of multimedia files. When a user triggers a click operation on an area where a certain multimedia file in the file list is located, the multimedia client can generate a play instruction for the multimedia file. Therefore, the multimedia client can respond to the playing instruction to analyze the multimedia file so as to obtain the initial metadata of the multimedia file. And, the multimedia client can also respond to the playing instruction to play the multimedia file.
Or, after the multimedia client finishes playing the first multimedia file, the multimedia client can automatically play the second multimedia file, and then the multimedia client can automatically generate a playing instruction for the second multimedia file. Therefore, the multimedia client can respond to the playing instruction aiming at the second multimedia file and analyze the second multimedia file to obtain the initial metadata of the second multimedia file. The second multimedia file is any one of a plurality of multimedia files stored in the terminal except the first multimedia file.
As another optional implementation manner, after the multimedia client is started, the multimedia client may parse the multimedia file to obtain the initial metadata of the multimedia file.
In the embodiment of the application, a plurality of clients can be installed in the terminal, and the icon of each client can be displayed on the display interface of the terminal. When a user triggers a click operation on an icon of a multimedia client in a plurality of clients, the terminal can respond to the click operation to start the multimedia client. And after the multimedia client is started, the multimedia client can automatically analyze the multimedia file pre-stored in the terminal, so as to obtain the initial metadata of the multimedia file.
Step 302, the multimedia client sends the initial metadata of the multimedia file to the server.
In the embodiment of the application, after acquiring the initial metadata of the multimedia file, the multimedia client may send the initial metadata to the server.
For example, assuming that after the multimedia client parses the multimedia client, the obtained initial metadata of the multimedia file includes an audio name and an album name, the multimedia client may send the audio name and the album name of the multimedia file to the server.
Step 303, the server obtains the complementary metadata of the multimedia file based on the initial metadata.
In the embodiment of the application, the server stores complete metadata of a plurality of files. After receiving the initial metadata of the multimedia file sent by the multimedia client, the server may obtain the complementary metadata of the multimedia file from a plurality of complete metadata stored in advance based on the initial metadata. The complementing metadata is metadata of the complete metadata of the multimedia file except the initial metadata. That is, the complete metadata includes the initial metadata and the complementary metadata.
By way of example, it is assumed that the complete metadata of the multimedia file stored in the server includes: audio name, lyrics, author, album name, album cover, encoding format, bitrate, file format, and file size. And, the initial metadata of the multimedia file received by the server includes an audio name and an album name. Therefore, the server can obtain the completion metadata of the multimedia file according to the initial metadata of the multimedia file, wherein the completion metadata of the multimedia file comprises lyrics, authors, album covers, encoding format, code rate, file format and file size.
Optionally, the multimedia client may first obtain complete metadata including the initial metadata based on the initial metadata, and then obtain complementary metadata in the complete metadata, excluding the initial metadata, based on the complete metadata and the initial metadata.
Of course, the initial metadata obtained by the multimedia client analyzing the multimedia file may have a low accuracy of some sub-data. The server may not be able to determine the complete metadata including the initial metadata based on the initial metadata sent by the multimedia client, and thus may not obtain the complementary metadata of the multimedia file.
Therefore, the server can determine complete metadata with the matching degree larger than the threshold value of the matching degree of the initial metadata based on the initial metadata sent by the multimedia client, and obtain the complementary metadata of the multimedia file based on the complete metadata and the initial metadata. The supplementary metadata is metadata of the complete metadata that is different from the original metadata.
The threshold of the matching degree may be a threshold of the matching degree stored in the server in advance. The matching degree of the initial metadata and the complete metadata may be measured by a ratio of the number of matching sub-data of the plurality of sub-data included in the initial metadata to the number of the plurality of sub-data included in the initial metadata. The larger the ratio is, the larger the matching degree of the initial metadata and the complete metadata is; the smaller the ratio, the smaller the matching degree of the initial metadata and the complete metadata. The matching subdata is subdata which is the same as the plurality of subdata of the complete metadata in the plurality of subdata of the initial metadata.
Step 304, the server sends the complementary metadata of the multimedia file to the multimedia client.
In the embodiment of the application, after acquiring the completion metadata of the multimedia file, the server may send the completion metadata to the multimedia client.
Of course, the initial metadata obtained by the multimedia client analyzing the multimedia file may have a low accuracy of some sub-data. Therefore, in order to ensure the accuracy of the metadata of the updated multimedia file, the server may send the complete metadata of the multimedia file to the multimedia client.
Step 305, the multimedia client encapsulates the complementary metadata into the multimedia file to obtain an updated multimedia file.
In this embodiment, the multimedia client receives the completion metadata sent by the server, and then the multimedia client can encapsulate the completion metadata into the multimedia file to obtain the updated multimedia file. Or, the multimedia client receives the complete metadata sent by the server, and then the multimedia client can encapsulate the multimedia file based on the received complete metadata of the multimedia file to obtain an updated multimedia file, so that the accuracy of the metadata of the updated multimedia file is ensured.
Because the updated metadata of the multimedia file is more perfect, the playing effect of the multimedia file played by the multimedia client is better. Moreover, since the updated multimedia file is obtained by the multimedia client by encapsulating according to the metadata (complementary metadata or complete metadata) sent by the server, the metadata of the updated multimedia file is not affected by the replacement of the player or the terminal. Even if the player or the terminal is replaced to play the multimedia file, the more complete metadata of the multimedia file can be used, and good experience of one-time completion and permanent use is achieved.
And step 306, displaying an updating interface of the multimedia file.
In the embodiment of the application, the multimedia client can display the update interface of the multimedia file in the application interface. The update interface may be displayed with initial metadata and complementary metadata. The initial metadata and the complementary metadata each include at least one child data. That is, the update interface may display at least one sub data included in the initial metadata and at least one sub data included in the complementary metadata.
For example, referring to FIG. 5, the plurality of child data displayed by the update interface may include: audio name, author, album name, encoding format, bitrate, file format, and file size.
And 307, responding to the selection operation aiming at the target subdata in the updating interface, and updating the file name of the multimedia file based on the target subdata.
In this embodiment of the application, when a user triggers a selection operation for target sub-data in an update interface, the multimedia client may respond to the selection operation and update a file name of a multimedia file based on the target sub-data. Referring to fig. 5, a selection button a1 for each child data may also be displayed in the update interface. The selection operation may be a click operation of the selection button a1 for updating the target sub data in the interface. Also shown in fig. 5 is a decision button, and when the user triggers a click operation for the decision button a2, the multimedia client may determine that the selection for the target sub data is completed in response to the click operation.
Optionally, the number of the target sub-data may be one or more. If the number of the target subdata is one, the multimedia client can directly determine the target subdata as the file name of the multimedia file.
If the number of the target subdata is multiple, the multimedia client may sort the multiple target subdata according to an execution sequence of the selection operation for the multiple target subdata, and determine the sorted multiple target subdata as the file name of the multimedia file. For example, assuming that the first target sub-data is an audio name, the second target sub-data is an author, and the user triggers a selection operation for the first target sub-data first, and then triggers a selection operation for the second target sub-data, the file name of the multimedia file determined by the multimedia client may be: audio name-author.
Or the multimedia client may store a naming rule of the file name of the multimedia file in advance, and the multimedia client may respond to the selection operation for the target sub-data in the update interface and determine the file name of the multimedia file according to the naming rule. The naming rule of the file name of the multimedia file is used for expressing: the order of the sub-data. For example, suppose the naming rule of the file name of a multimedia file is: an audio name; a file format; an author; the file size, and the target subdata includes an audio name and an author, the file name of the multimedia file determined by the multimedia client may be: audio name-author.
For example, assume that the audio name of a multimedia file is: abcd, authored by YYY. The file name of the multimedia file before update is: ssdsfsdfa. Referring to fig. 6, the file name of the updated multimedia file is abcd-YYY. Wherein, the album cover a3 of the updated multimedia file can also be displayed in the application interface of the multimedia client. Also, referring to fig. 6, the application interface of the multimedia client may also display related information of other multimedia files, for example, file names of two other multimedia files, which are ZZZ and AAA, may be displayed. The file names of the other multimedia files shown in fig. 6 may be file names updated by the method provided in the embodiment of the present application, or may be file names before updating.
It should be noted that the order of the steps of the file updating method provided in the embodiment of the present application may be appropriately adjusted, and the steps may also be correspondingly increased or decreased according to the situation. For example, step 306 and step 307 may be performed before step 305, or step 306 and step 307 may be deleted according to the circumstances, and any method that can be easily conceived by those skilled in the art within the technical scope disclosed in the present application shall be covered by the protection scope of the present application, and thus, the description thereof shall not be repeated.
In summary, the embodiment of the present application provides a file updating method, in which a multimedia client in the method can obtain completion metadata of a multimedia file from a server, and update the multimedia file based on the completion metadata. Therefore, the updated metadata of the multimedia file can be ensured to be perfect, and the playing effect of the multimedia file played by the multimedia client is better. In addition, the file updating method provided by the embodiment of the application realizes the perfection of the metadata of the multimedia file through the interaction between the multimedia client and the server, and does not need the manual completion of data by a user, so that the efficiency of perfecting the metadata is higher, and the updating efficiency of the multimedia file is further improved.
