Description

TECHNICAL FIELD

[0001] The present application relates to the field of audio and video technology, and in particular to a song library updating method and device, equipment and a storage medium. BACKGROUND

[0002] With the increasing popularity of KTV, the demand for stand-alone KTV devices (referred to as stand-alone devices) has surged. In order to save traffic, a large number of song files are retained in the hard disk of the stand-alone device, and the stand-alone device also contains an SD card, which stores the path of the song in the hard disk. When the song ordering application in the stand-alone device starts, the application only needs to read the song path in the SD card to realize related operations such as singing, deleting, downloading, etc.

[0003] However, since the song ordering application only reads the song path in the SD card, if the file storing the song path in the hard disk is missing, the song path stored in the SD card will be invalid, which will cause the device to be unable to realize the song ordering function, affecting the user's experience.

[0048] It should be understood that the specific embodiments described herein are intended to explain the application and are not intended to limit the application.

[0049] REFERENCE Figure 1 , Figure 1 A structure diagram of a music library updating device related to a hardware running environment of an embodiment of the application.

[0050] As Figure 1As shown in the figure, the music library updating device can include a processor 1001, such as a central processing unit (CPU), a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005. The communication bus 1002 is used to realize the connection and communication between the components. The user interface 1003 can include a display, an input unit such as a keyboard, and can also include a standard wired interface, a wireless interface. The network interface 1004 can optionally include a standard wired interface, a wireless interface (such as a wireless fidelity (Wi-Fi) interface). The memory 1005 can be a high-speed random access memory (RAM) or a stable non-volatile memory (NVM), such as a disk memory. The memory 1005 can also be a storage device independent of the aforementioned processor 1001.

[0051] Those skilled in the art can understand that Figure 1 The structure shown in the figure does not constitute a limitation on the music library updating device, and can include more or fewer components than the figure, or combine certain components, or different component arrangements.

[0052] As Figure 1 As shown in the figure, the memory 1005 as a storage medium can include an operating system, a network communication module, a user interface module, and a music library updating program.

[0053] In Figure 1 In the music library updating device shown in the figure, the network interface 1004 is mainly used for data communication with a network server; the user interface 1003 is mainly used for data interaction with a user; the processor 1001 and the memory 1005 in the music library updating device of the present application can be arranged in the music library updating device, and the music library updating device calls the music library updating program stored in the memory 1005 through the processor 1001, and executes the music library updating method provided by the embodiments of the present application.

[0054] The present application provides a music library updating method, which is described with reference to Figure 2 , Figure 2 The flowchart of the first embodiment of the music library updating method of the present application is shown in the figure.

[0055] In this embodiment, the music library updating method includes the following steps:

[0056] Step S10: Detect whether a hard disk music library exists in the hard disk.

[0057] It should be noted that the execution subject of the method of the embodiment can be a computing service device with a song library updating function, a data processing function, a network communication function, and a program running function, for example, a song ordering machine, and can also be other electronic devices with the same or similar functions, such as the song library updating device described above. The following describes the embodiment and each of the following embodiments with reference to the song library updating device.

[0058] It can be understood that the hard disk song library can be a database in the hard disk storing song file information. The song file information can be song path information or path information used to describe the position of the song in the hard disk.

[0059] In a specific implementation, the song library updating device is taken as the execution subject, which can be in the stand-alone song ordering machine. If the song ordering machine is replaced with a new hard disk, there can be a situation that the hard disk song library has not been added, or the user accidentally deletes the hard disk song library, resulting in loss of the hard disk song library. Therefore, the song library updating device needs to detect whether the hard disk song library exists in the hard disk when the song ordering machine starts, to avoid the situation that the hard disk song library is missing in the hard disk, resulting in failure to implement the song ordering function.

[0060] Step S20: If the hard disk song library does not exist, performing full-disk scanning on the hard disk to obtain all target song paths in the hard disk that meet a preset naming rule.

[0061] It should be noted that the preset naming rule can be set by a technician and is a special naming mode for a song path. That is, the song path is named by the preset naming rule, and it is determined that the file is a song path when it is detected that the file name is named by the preset naming rule.

[0062] It can be understood that although the hard disk song library is missing in the hard disk, there are still actual songs that can be played in the hard disk, and the actual songs in the hard disk have corresponding paths, that is, the song paths are not in the hard disk song library but can be in other positions in the hard disk. Accordingly, the target song path can be a song path in a position in the hard disk other than the hard disk song library.

[0063] In a specific implementation, when the song library updating device detects that the hard disk song library does not exist in the hard disk, in order to ensure that the SD card song path is consistent with the hard disk song path, the hard disk is scanned to obtain the target song path that meets the preset naming rule.

[0064] Step S30: Synchronizing the SD card song path in the SD card song library to the target song path.

[0065] It should be noted that the SD card song library can be a database in the SD card storing song file information.

[0066] In a specific implementation, the song library updating device can delete the stored SD card song path in the SD card song library when detecting that the hard disk song library is missing in the hard disk, then copy the target song path, insert the copied target song path into the SD card song library, and take the target song path as the SD card song path of the SD card, thereby realizing synchronization of the SD card song path and the target song path.

[0067] Step S40: copying the path-synchronized SD card song library to obtain the hard disk song library, and updating the hard disk song library to the hard disk.

[0068] In a specific implementation, the song library updating device can copy the path-synchronized SD card song library, insert the copied SD card song library into the hard disk as the hard disk song library of the hard disk, thereby reconfiguring the hard disk song library for the hard disk, and also synchronizing the hard disk song library with the SD card song library, and ensuring implementation of the song ordering function of the jukebox.

[0069] The method includes detecting whether the hard disk song library exists in the hard disk, performing full-disk scanning on the hard disk to obtain all target song paths in the hard disk that meet a preset naming rule, synchronizing the SD card song path in the SD card song library to the target song path, copying the path-synchronized SD card song library to obtain the hard disk song library, and updating the hard disk song library to the hard disk. The method synchronizes the SD card song path in the SD card song library to the target song path in the hard disk that meets the preset naming rule when the hard disk song library does not exist, avoids a problem that, in the prior art, if a file storing a song path is missing in the hard disk, the song path stored in the SD card is invalid, and the device cannot implement the song ordering function, and effectively ensures implementation of the song ordering function, thereby improving user experience.

[0070] Reference Figure 3 , Figure 3 FIG. 2 is a flowchart of a second embodiment of the song library updating method.

[0071] Based on the first embodiment, in the present embodiment, the step of performing full-disk scanning on the hard disk to obtain all target hard disk song paths in the hard disk that meet a preset naming rule includes:

[0072] Step S201: performing full-disk scanning on the hard disk to determine whether a target file whose file name contains a preset keyword exists in each file of the hard disk.

[0073] It should be noted that the preset keyword can be a keyword for determining whether a song path exists in a song file, and the preset keyword can be a suffix of the file name.

[0074] In a specific implementation, the music library updating device can perform a full-disk scan on the hard disk, and determine whether the file name suffix of each file in the hard disk contains the preset keyword. For example, for an xxx.mp3 file, it is only necessary to determine whether the file name contains.mp3.

[0075] Step S202: If there is a target file whose file name contains the preset keyword in each file of the hard disk, it is determined that the target song path conforming to the preset naming rule is stored in the target file, and the target song path is extracted.

[0076] In a specific implementation, when the music library updating device detects that the file name of a file contains the preset keyword, it is determined that the target song path conforming to the preset naming rule is stored in the file, and the target song path is extracted accordingly. Accordingly, the file that stores the target song path conforming to the preset naming rule is the target file.

[0077] It should be understood that the existing full-disk scan method uses a song name regular matching method for searching. Regular matching involves complex calculations, for example, regular expression parsing: the regular expression itself needs to be parsed into a sequence of ordered operations to perform matching operations on the target string. Finite state automaton: the regular expression is usually interpreted as a finite state automaton (FSA), in which each character is converted into a state, and each operator in the regular expression produces some state transitions. Backtracking: when performing regular expression matching, multiple possible matches need to be considered. In some cases, the regular expression engine needs to backtrack to try different matching methods until a feasible match is found. Nested expressions: regular expressions can contain nested expressions, such as nested sub-expressions in parentheses, which may require additional calculations to perform. Pre-compilation and optimization: in practical applications, regular expressions usually need to be pre-compiled and optimized to achieve better performance when performing matching. These preprocessing and optimization processes also require some calculation cost.

[0078] It should be noted that the present embodiment uses a method of determining whether the file name suffix of a file contains a preset keyword, which is a suffix-based matching method. After the file is specified, it is only necessary to determine whether the file name contains the specified keyword, without involving complex operations of regular matching, thereby effectively improving the efficiency of full-disk scanning.

[0079] Reference Figure 4 , Figure 4 FIG. 2 is a flowchart of a music library updating method according to a third embodiment of the present application.

[0080] Based on the above embodiments, in the present embodiment, after the step S10, further comprising:

[0081] Step S20': if the hard disk song library exists, detecting whether the hard disk song path in the hard disk song library is consistent with the SD card song path in the SD card song library.

[0082] In a specific implementation, the song library updating device can determine whether the hard disk song path is consistent with the SD card song path by checking whether the hard disk song library identifier of the hard disk song library and the SD card song library identifier of the SD card song library are consistent.

[0083] Further, in the present embodiment, the step S20' comprises:

[0084] Step S201': detecting whether the hard disk song library identifier of the hard disk song library is consistent with the SD card song library identifier of the SD card song library.

[0085] It should be noted that the SD card song library identifier can be an identifier for representing the song path in the SD card song library, and is used to determine whether the song path in the SD card song library is consistent with the song path in the hard disk song library.

[0086] It can be understood that the hard disk song library identifier can be an identifier for representing the song path in the hard disk song library, and is used to determine whether the song path in the hard disk song library is consistent with the song path in the SD card song library.

[0087] It should be noted that the existing stand-alone karaoke machine system is based on an Android native system + external hard disk form. The Android native system is responsible for running the karaoke machine program, and the external hard disk (master disk) is responsible for storing song-related multimedia files. The Android system has a small capacity of SD card (not removable), and the SD card mainly saves song-related song library files. The song library saves the song path in the hard disk, which facilitates the playback of the song. When the karaoke application starts, the application reads the song information from the song library file in the SD card, performs singing, deleting, downloading, and other related operations. The above-mentioned method can avoid deleting the song resource in the hard disk directly when deleting, blacklisting, etc. For example, when deleting a song, only the song path field under the SD card needs to be deleted, and there is no need to really delete the song file under the hard disk, which effectively protects the hard disk. However, in order to ensure that the song path stored in the SD card is consistent with the actual position of the song in the hard disk, the existing method is to scan all the song paths in the hard disk song library and compare them with the song paths stored in the SD card when the device starts, which results in a long device startup time and affects the user experience.

[0088] In a specific implementation, the embodiment takes a music library updating device as an execution subject, which can be in the stand-alone jukebox. To solve the above problem, the music library updating device can generate the hard disk music library identifier based on the hard disk music library, generate the SD card music library identifier based on the SD card music library, and compare the hard disk music library identifier with the SD card music library identifier to determine whether the song paths in the SD card music library and the hard disk music library are consistent.

[0089] Step S202': determining whether the hard disk song path in the hard disk music library and the SD card song path in the SD card music library are consistent based on the detection result.

[0090] In a specific implementation, if the hard disk music library identifier and the SD card music library identifier are consistent, it can be determined that the song paths in the SD card music library and the hard disk music library are consistent, otherwise, if the hard disk music library identifier and the SD card music library identifier are inconsistent, it can be determined that the song paths in the SD card music library and the hard disk music library are inconsistent, without scanning all the song paths in the hard disk music library and comparing them with the song paths stored in the SD card, effectively reducing the device startup time and improving the user experience.

[0091] Step S30': if inconsistent, synchronizing the SD card song path to the hard disk song path.

[0092] In a specific implementation, when the determination result is that the SD card song path in the SD card music library and the hard disk song path in the hard disk music library are inconsistent, the music library updating device can update the SD card song path based on the hard disk song path in the hard disk music library, so that the SD card song path in the SD card music library is consistent with the hard disk song path.

[0093] Further, in the embodiment, after the step of synchronizing the SD card song path to the hard disk song path, the method further includes:

[0094] Step S31': updating the SD card music library identifier and synchronizing the hard disk music library identifier to the updated SD card music library identifier.

[0095] It should be noted that, since the embodiment detects whether the hard disk song path and the SD card song path are consistent through the hard disk music library identifier and the SD card music library identifier, after the synchronization of the hard disk song path and the SD card song path is completed, the hard disk music library identifier and the SD card music library identifier also need to be synchronized.

[0096] In the specific implementation, after the SD card song path in the SD card library is updated and the SD card song path in the SD card library is synchronized with the hard disk song path in the hard disk library, the SD card library identifier is updated again, and then the updated SD card library identifier is copied to the hard disk library. Correspondingly, the hard disk library identifier is replaced by the updated SD card library identifier, so that the hard disk library identifier is consistent with the SD card library identifier, and the logical implementation that the hard disk song path is consistent with the SD card song path under the condition that the hard disk library identifier is consistent with the SD card library identifier is ensured.

[0097] And / or, the step S30 further comprises:

[0098] Step S31: updating the SD card library identifier, and synchronizing the hard disk library identifier to the updated SD card library identifier.

[0099] In the specific implementation, after the synchronization of the SD card library and the hard disk library is completed, the SD card library identifier of the SD card library can be updated, and then the hard disk library identifier is synchronized to the SD card library identifier. After the jukebox is started, it is only necessary to compare whether the SD card library identifier and the hard disk library identifier are consistent to determine whether the song path in the SD library and the song path in the hard disk library are consistent, thereby effectively improving the efficiency.

[0100] It should be understood that, since the SD card library identifier and the hard disk library identifier are synchronized, it can be determined that the song path in the SD library and the song path in the hard disk library are consistent, and the jukebox can normally operate, without the need to sequentially scan the hard disk song path in the hard disk library and the SD card song path in the SD card library to sequentially compare when starting, thereby effectively improving the starting efficiency.

[0101] For the convenience of understanding, reference Figure 5 is made to the description, but the present solution is not limited thereto. Figure 5 The present solution is a library updating method and device, and a jukebox. Figure 5 In the specific implementation, after the SD card song path in the SD card library is updated and the SD card song path in the SD card library is synchronized with the hard disk song path in the hard disk library, the SD card library identifier is updated again, and then the updated SD card library identifier is copied to the hard disk library. Correspondingly, the hard disk library identifier is replaced by the updated SD card library identifier, so that the hard disk library identifier is consistent with the SD card library identifier, and the logical implementation that the hard disk song path is consistent with the SD card song path under the condition that the hard disk library identifier is consistent with the SD card library identifier is ensured.

[0102] Further, in order to ensure that different hard disks can be compatible, in the embodiment, the step of synchronizing the SD card song path to the hard disk song path comprises:

[0103] Step S301': deleting the stored SD card song path in the SD card song library.

[0104] In a specific implementation, when the hard disk song library identifier and the SD card song library identifier are detected to be inconsistent, it indicates that the currently stored SD card song path in the SD card song library is inconsistent with the hard disk song path in the hard disk song library, and the stored SD card song path in the SD card song library can be deleted to facilitate subsequent synchronization of the hard disk song path.

[0105] Step S302': obtaining the hard disk song path and inserting the hard disk song path into the SD card song library to synchronize the current SD card song path in the SD card song library to the hard disk song path.

[0106] In a specific implementation, since the hard disk song path is stored in the hard disk song library, the library updating device can extract the hard disk song library from the hard disk, query all the hard disk song paths in the hard disk song library, extract all the hard disk song paths, and re-write all the extracted hard disk song paths into the SD card song library, so that the written hard disk song path is used as a new SD card song path, thereby completing synchronization of the SD card song path and the hard disk song path.

[0107] It should be understood that the existing single-machine version jukebox hard disk is detachable, and the SD card is not detachable. If the hard disk is replaced, the hard disk song path in the new hard disk will be inconsistent with the SD card song path in the SD card song library, that is, the new hard disk is incompatible with the single-machine version jukebox. In order to solve this problem, when the hard disk song path and the SD card song path are detected to be inconsistent through the hard disk song library identifier and the SD card song library identifier, the library updating device deletes the stored SD card song path in the SD card song library, and then updates the hard disk song path queried in the hard disk song library to the SD card song library. The hard disk song path updated to the SD card song library is used as the SD card song path in the SD card song library. Different hard disks can be processed in this way, thereby avoiding the problem that the hard disk song path in the new hard disk is inconsistent with the SD card song path in the SD card song library, realizing compatibility of different hard disks, and avoiding the problem that the hard disk inserted is not the original hard disk, resulting in failure of song jukebox playing.

[0108] Correspondingly, in the embodiment, the step S30 comprises:

[0109] Step S301: deleting the stored SD card song path in the SD card library.

[0110] In a specific implementation, the operation process of synchronizing the SD card song path in the SD card library as the target song path can be consistent with the operation process of synchronizing the SD card song path as the hard disk song path in the case that the hard disk library exists in the hard disk, that is, deleting the stored SD card song path in the SD card library, so as to facilitate the subsequent hard disk song path synchronization.

[0111] Step S302: inserting the target song path into the SD card library to synchronize the SD card song path as the target song path.

[0112] In a specific implementation, since the target song path has been obtained before the operation of synchronizing the SD card song path in the SD card library as the target song path is performed in the case that the hard disk library does not exist in the hard disk, the target song path can be directly rewritten into the SD card library, and the written target song path is taken as a new SD card song path, so as to complete the synchronization of the SD card song path and the target song path.

[0113] Further, in the embodiment, the step of inserting the target song path or the hard disk song path into the SD card library comprises:

[0114] Step S3021': grouping the target song path or the hard disk song path to obtain a plurality of song path array sets.

[0115] In a specific implementation, the library updating device can slice and group the extracted target song path or the hard disk song path based on a preset rule, that is, if the target song path is obtained, the target song path is grouped, and if the hard disk song path is obtained, the hard disk song path is grouped, and the song paths in the same group are taken as a song path array set, so as to obtain a plurality of song path group sets.

[0116] It should be understood that the above-mentioned preset rule can be a rule for grouping preset by a technician. For example, two by two in the order, or ten files in a group, etc.

[0117] Step S3022': sequentially inserting the plurality of song path array sets into the SD card library.

[0118] It should be noted that the existing song path updating scheme is to scan all the hard disk song paths and insert them into the SD card library at one time. Due to the low performance of the stand-alone jukebox, reading a large amount of data at one time will consume a large amount of memory resources of the device, resulting in a decrease in the stability of the device, and due to the insufficient cache of the SD card library, the insertion efficiency will also be reduced.

[0119] In a specific implementation, the library updating device synchronizes the SD card song paths in the SD card library to the target song paths by grouping the target song paths, obtaining a plurality of groups of song path files, and then inserting the groups of song path files into the SD card library. Since the insertion is in groups, the amount of data inserted at one time is reduced, thereby reducing memory consumption, the cache of the SD card library is not full, and the insertion speed of the SD card library is improved, thereby effectively improving the efficiency of updating the target song paths.

[0120] It should be understood that the execution process of inserting the target song paths into the SD card library in the case where the hard disk does not have a hard disk library is consistent with the description in steps S3021' and S3022' in the case where the hard disk library in the hard disk is operated, and this embodiment will not be described again here.
