Description

Multimedia file recovery method, device, terminal and storage medium

Technical Field

The disclosure relates to the technical field of internet, and in particular relates to a multimedia file recovery method, a device, a terminal and a storage medium.

Background

With the development of internet technology, the functions of application clients in terminals are becoming more and more powerful. For example, the music application client in the terminal can not only play songs online, but also collect songs, so that the user can conveniently play the collected songs later. In order to ensure the reliability of the collected songs, the terminal can generate a song list based on the collected songs, wherein the song list comprises information such as song names of the collected songs, the song list is synchronized to a server corresponding to the music application client, and when the locally collected songs are lost, the terminal can recover the collected songs from the server based on the song list.

Currently, when a terminal synchronizes the song to a server, the server generates a version number (for convenience of distinction, the version number is referred to as a first version number) for the song, the first version number is issued to the terminal, and the terminal stores the first version number locally. When the terminal starts the music application, the terminal acquires a version number (called a second version number) of the song stored in the server from the server, and determines whether the first version number and the second version number are consistent; when the songs are inconsistent, all songs in the song list are acquired from the server, and the songs collected locally are replaced by all songs in the song list.

Since the related art only compares the version numbers, when the locally collected songs are lost, but the version numbers of the song list are not changed, in this case, the terminal cannot recover the songs from the server, i.e. cannot recover the collected songs, resulting in poor reliability of recovery.

The first update instruction may be a first delete instruction or a first add instruction. Accordingly, the first multimedia identifier to be updated may be the first multimedia identifier to be deleted or the first multimedia identifier to be added.

When the first update instruction is a first delete instruction, this step may be: the terminal displays a collection interface corresponding to the collection label, wherein the collection interface comprises at least one multimedia identifier; when a deleting operation of any multimedia identifier is received, determining that a first updating instruction of the multimedia file in the collection label is received, and taking the any multimedia identifier as a first multimedia identifier.

When the first update instruction is a first add instruction, this step may be: when the terminal receives the adding operation of any multimedia identifier, the terminal determines that a first updating instruction of the multimedia file in the collection label is received, and the any multimedia identifier is used as a first multimedia identifier.

The multimedia application client of the terminal comprises at least one collection label; the terminal can update the multimedia files in any one of the collection labels, or update the multimedia files in all the collection labels. When the terminal updates the multimedia files in any one of the collection labels, the subsequent steps can be used for recovering the multimedia files in the collection labels, and the recovery operation can be performed on the multimedia files in a plurality of or all of the collection labels.

For example, the multimedia application client includes 4 collection tabs, respectively, "i like," "love," "aging," and "Tong Ge. When a user adds a song to the favorite collection label, the terminal can only restore the multimedia files in the favorite collection label, and can restore the multimedia files in the favorite collection labels, namely, love song, aging song and Tong Ge.

It should be noted that, when the terminal performs a recovery operation on the multimedia files in the plurality of collection labels, the terminal may perform a recovery operation on the multimedia files in the collection label that is updated recently by the user, or may obtain the collection label that should be recovered currently according to a recovery rule set by the user. For example, the restoration rule is a restoration order of at least one collection label, and the terminal selects one collection label from the at least one collection label according to the restoration order.

302. And the terminal updates a third multimedia list corresponding to the collection label currently according to the first multimedia identifier to obtain a first multimedia list.

And before the third multimedia list receives the first updating instruction, the terminal collects the multimedia list corresponding to the tag. And when the collection tag does not collect the multimedia file before receiving the first update instruction, the third multimedia list is empty. When at least one multimedia file has been collected in the collection tag before the first update instruction is received, the multimedia identification of the at least one collected multimedia file is included in the third multimedia list.

The first multimedia list includes at least one multimedia identifier, which is an identifier of at least one multimedia file collected by the collection tag. For example, when the multimedia file is a song, the first multimedia list may be a song list corresponding to the collection label, where the song list includes an identification of at least one song.

It should be noted that, after the terminal obtains the first multimedia identifier to be updated, the synchronization request server updates the multimedia list, and the process may be: and the terminal sends a first update request to the server, wherein the first update request carries the first multimedia identifier. The server receives the first updating request, updates a fourth multimedia list corresponding to the collection label currently according to the first multimedia identifier to obtain a second multimedia list, acquires a second version identifier and second list information of the second multimedia list, and stores the second version identifier and the second list information so as to return the second version identifier and the second list information to the terminal when the terminal requests to acquire the second version identifier and the second list information.

The fourth multimedia list is a collection list corresponding to the collection label stored in the server, and the fourth multimedia list is a multimedia list corresponding to the collection label before the server receives the first update request. And, when the collection tag does not collect the multimedia file before receiving the first update request, the fourth multimedia list is empty. When at least one multimedia file has been collected in the collection tag before the first update request is received, the fourth multimedia list includes multimedia identifications of the at least one multimedia file that has been collected.

And when the first updating request is a first deleting request, deleting the first multimedia identifier in the fourth multimedia list by the server to obtain a second multimedia list. And when the first updating request is a first adding request, adding a first multimedia identifier in the fourth multimedia list by the server to obtain a second multimedia list.

When the server adds the first multimedia identifier to the fourth multimedia list, the first multimedia identifier may be directly added to the end of the fourth multimedia list, or may be added to a position corresponding to the category of the fourth multimedia list according to the category corresponding to the first multimedia identifier. For example, the multimedia may be a song, the type corresponding to the first multimedia identifier is a love song, and the server adds the song to the location corresponding to the love song.

Another point to be described is that the terminal does not have strict time sequence for updating the local multimedia list and requesting the server to update the multimedia list, and the terminal can update the local multimedia list first and then request the server to update the multimedia list. The server may be requested to update the multimedia list before the local multimedia list is updated, or the server may be requested to update the multimedia list while the local multimedia list is being updated.

303. The terminal acquires first list information of a first multimedia list and stores the first list information.

The first list information may include at least one of a first number of multimedia identifications in the first multimedia list, a first encoding result obtained by encoding the multimedia identifications in the first multimedia list, and a time of generating the first multimedia list. The first encoding result may be a hash value obtained by performing a hash operation on the multimedia identifier in the first multimedia list, and the like.
