Thus, appearances of the phrases "in one embodiment," "in some embodiments," "in other embodiments," and the like in the specification are not necessarily all referring to the same embodiment, but mean "one or more but not all embodiments" unless expressly specified otherwise.
At present, most of audio playing devices in a car cannot be connected to a network, and many times, a user needs to use a USB flash disk to play music.
The method specifically comprises the steps of firstly storing audio files in a U disk, then inserting the U disk onto vehicle-mounted equipment (namely an external interface of audio playing equipment on a vehicle), and carrying out audio playing by the audio playing equipment of the vehicle through loading the audio playing files in the U disk.
In actual use, people usually directly purchase a USB flash disk specially stored with audio files for vehicle-mounted audio playing, thousands of audio files or even tens of thousands of audio files are generally stored in the USB flash disk, and the audio playing equipment of a vehicle needs to consume a large amount of time and resources to scan the whole disk after recognizing the USB flash disk each time so as to acquire the audio files, so that the audio playing can not be quickly performed after detecting the USB flash disk, the problem of low audio loading speed exists, and the use experience of users is greatly influenced.
In order to solve the above technical problems, embodiments of the present application provide a method for playing an audio file, where the method is applied to a terminal and can be executed by a playing device of the audio file on the terminal.
In this embodiment of the present application, the terminal may be an intelligent terminal that may implement audio playback by loading an audio file in an external device connected to the terminal, such as a vehicle, a desktop computer, or a notebook computer.
The above audio file may be stored in an external device connected to the terminal. The external device may be a storage device such as a usb disk or a magnetic disk.
It should be noted that, the specific types of the above-mentioned intelligent terminal and the external device are not limited in this application, and for convenience of explanation of the technical solution of this application, the above-mentioned terminal is used as a vehicle, and the above-mentioned external device is used as a usb disk for illustration.
Referring to fig. 1, the method for playing an audio file in the embodiment of the present application may include steps 101 to 103.
In step 101, when an external device connected to the terminal is detected, it is detected whether an audio list file corresponding to an audio file is stored in the external device.
In the embodiment of the present application, whether the audio list file corresponding to the audio file is stored in the external device may be detected based on the file name of the audio list file.
The audio list file may be named based on, among other things, the vendor identification code (VID), the product identification code (PID), and the hardware serial number (sn) of the external device.
When the terminal is a vehicle, the vehicle may monitor an insertion state of the external device after each start, and detect whether a file named by a vendor identification code (VID), a product identification code (PID), and a hardware serial number (sn) of the external device is stored in the external device when the external device connected to the terminal is detected, and determine whether an audio list file corresponding to the audio file is stored in the external device.
For example, it is detected whether an audio list file having a file name vid_pid_sn.txt is stored in the external device, and the following step 102 or step 103 is continuously performed according to the detection result.
It should be noted that the foregoing is merely illustrative of the naming manner of the audio list file, and it is understood that in some embodiments of the present application, the audio list file may be named based on other manners.
For example, the "audio list file" may be directly used as a file name, and the audio list file corresponding to the audio file in the external device may be named, which is not limited in this application.
In step 102, if the audio list file corresponding to the audio file is not stored in the external device, the audio file in the external device is scanned, and when any one of the target audio files is scanned, the target audio file is played.
In this embodiment of the present application, when an audio list file corresponding to an audio file is not stored in an external device, it indicates that the external device is connected to the terminal for the first time, so that it is necessary to scan the audio file in the external device, and after obtaining a storage path of any one target audio file, play the target audio file based on the storage path.
In the process of scanning the audio files in the external device, files conforming to the specified format can be used as the audio files. For example, a file in which one or more of MP3 format, WAV format, WMA format, MP2 format, flac format, MIDI format, RA format, APE format, AAC format, CDA format, MOV format can be played by the terminal is used as an audio file.
According to the method and the device, in the process of scanning the audio files in the external equipment, when any one target audio file in the audio files is scanned, the target audio file is directly played, instead of waiting for the completion of the full-disc scanning of the external equipment, then the audio playing is started, and therefore the loading speed of the audio can be improved.
In some embodiments of the present application, in order to enable the external device to connect to the terminal next time, audio playing may be performed based on the audio list file, after the step 102, scanning may be continued on the audio file in the external device, and the audio list file may be generated and stored according to the scanning result.
Specifically, in the process of generating the audio list file according to the scanning result, the storage path and the file identifier of the scanned audio file may be stored in a list form, that is, the audio list file carrying the storage path and the file identifier of the audio file in the external device is generated.
When the audio list file is stored, the audio list file can be stored on an external device or a terminal.
Specifically, when the audio list file is stored, the storage space required to be occupied by the generated audio list file and whether the remaining storage space of the external device is larger than the storage space required to be occupied by the audio list file can be calculated first, and when the remaining storage space of the external device is larger than the storage space required to be occupied by the audio list file, the generated audio list file is stored in the external device, so that when the external device is connected with other terminals, the other terminals can realize quick play of the audio based on the audio list file.
In some embodiments of the present application, when the remaining storage space of the external device is smaller than or equal to the storage space that needs to be occupied by the audio list file, the generated audio list file may also be stored in the terminal, and accordingly, the step 102 may specifically be: if the audio list file corresponding to the audio file is not stored in the external device, detecting whether the audio list file corresponding to the audio file is stored in the terminal, if the audio list file corresponding to the audio file is not stored in the terminal, scanning the audio file in the external device, and playing the target audio file when any one target audio file in the audio files is scanned.
That is, when it is detected that the audio list file is not stored in the external device, it is first detected whether the audio list file is also not stored in the terminal, and when the audio list file is stored in the terminal, the audio file stored in the external device is played based on the audio list file stored in the terminal, and when the audio list file is also not stored in the terminal, the audio file in the external device is scanned, and when any one of the target audio files is scanned, the target audio file is played.
In addition, in some embodiments of the present application, when the audio list file is saved, in order to avoid that the audio list file is deleted by mistake, the attribute of the audio list file may also be set as a hidden attribute.
In step 103, if the external device stores the audio list file corresponding to the audio file, the audio file stored in the external device is played according to the audio file information carried in the audio list file.
In this embodiment of the present application, the audio file information carried in the audio list file may include a storage path and a file identifier of an audio file stored in the external device.
The file identifier may include a file name of the audio file.
In an embodiment of the present application, in implementing the foregoing step 103, in a process of playing an audio file stored in an external device according to audio file information carried in an audio list file, audio file playing may be performed according to a storage path and a file identifier of any one audio file stored in the external device carried in the audio list file, so that when the terminal detects an external device connected to the external device, and when the external device stores an audio file list, audio playing may be performed directly according to the audio file list, without waiting for the terminal to perform full-disc scanning on the external device, and then performing audio playing, thereby improving a loading speed of the audio file.
In another embodiment of the present application, the audio file information carried in the audio list file may further include a file identifier and a storage path of a currently played audio file when the terminal ends playing the audio file. Correspondingly, in the process of playing the audio file stored in the external device according to the audio file information carried in the audio list file in the step 103, the current playing audio file stored in the external device can be played according to the file identifier and the storage path of the current playing audio file when the terminal finishes playing the audio file.
Specifically, when an audio list file corresponding to an audio file is stored in the external device, it indicates that the external device is not connected to the terminal for the first time, and in the last connection process between the external device and the terminal, the file identifier and the storage path of the audio file being played by the terminal can be recorded in the audio list file.
For example, the terminal may record the file identification and the storage path of the audio file being played by the terminal in the audio list file each time the audio file play is ended, so that the terminal may continue playing the audio file from the position where the audio file play was last ended when the external device is connected to the terminal next time.
When the terminal is a vehicle, after the vehicle is restarted, the audio playing device of the vehicle can directly read the file identifier and the storage path of the current playing audio file when the terminal carried in the audio list file in the U disk finishes playing the audio file when detecting that the U disk is inserted in the vehicle, so as to position the playing position of the audio file to the last playing position and continue playing the audio file.
In practical application, since the user may modify the audio file in the external device after finishing playing the audio file, so that the audio file corresponding to the file identifier and the storage path of the currently played audio file does not exist in the external device, in one embodiment, in the process of playing the currently played audio file stored in the external device according to the file identifier and the storage path of the currently played audio file, when the audio file corresponding to the file identifier and the storage path of the currently played audio file exists in the external device, the terminal may directly play the currently played audio file; when the file identifier of the current playing audio file and the audio file corresponding to the storage path do not exist in the external device, the terminal can play the next audio file corresponding to the current playing audio file according to the audio list file.
In addition, in order to improve the accuracy of the audio list file, as shown in fig. 2, in an embodiment of the present application, after the above step 103, the following step 104 may be further performed: rescanning the audio files in the external device, and updating the audio list files according to the rescanning result.
Specifically, in the process of updating the audio list file according to the rescanning result, in order to ensure the integrity of the audio list file, the audio list file is prevented from being damaged due to the fact that the external device is suddenly disconnected from the terminal in the process of reading and writing the audio list file, as shown in fig. 3, the step 104 may be specifically implemented by adopting the following steps 301 to 302.
Step 301, backing up the audio list file to obtain a backup file.
Step 302, updating the backup file according to the rescanning result, and copying the backup file when the backup file updating is completed to obtain an audio list file.
For example, the audio list file vid_pid_sn.txt is backed up as the backup file vid_pid_sn_bak.txt, then the backup file vid_pid_sn_bak.txt is updated according to the rescanning result, and when the update of the backup file vid_pid_sn_bak.txt is completed, the backup file vid_pid_sn_bak.txt is copied as the audio list file vid_pid_sn.txt, thereby obtaining the updated audio list file.
Based on the above update manner of the audio list file, correspondingly, in an embodiment of the present application, as shown in fig. 4, in implementing the above step 103, according to the audio file information carried in the audio list file, in playing the audio file stored in the external device, the following manners of steps 401 to 403 may also be specifically adopted.
In step 401, it is detected whether the audio list file is complete.
In this embodiment, the audio list file may be provided with an end-of-file identifier, and in implementing step 401, the integrity of the audio list file may be detected based on the end-of-file identifier.
For example, the end of file identifier may be a fixed value, such as 0x5A5A5A5A, etc., upon detecting that the last 4 bytes of data of the audio list file is 0x5A5A5A5A, it may be determined that the audio list file is complete, upon detecting that the last 4 bytes of data of the audio list file is not 0x5A, it may be determined that the audio list file is incomplete, i.e., the audio list file is corrupted.
Step 402, if the audio list file is complete, playing the audio file stored in the external device according to the audio file information carried in the audio list file.
Step 403, if the audio list file is incomplete, playing the audio file stored in the external device according to the audio file information carried in the backup file.
Specifically, since the audio list file is complete, it indicates that the audio list file is not updated, or that the updating has been completed successfully, that is, steps 301 to 302 are executed successfully, so that the audio file stored in the external device may be played directly according to the audio file information carried in the audio list file.
When the audio list file is incomplete, it means that the above-mentioned step 302 is not successfully performed, and the process of copying the backup file is not successfully performed after the backup file is updated, and at this time, the backup file is updated and is complete, so that the audio file stored in the external device can be played based on the audio file information carried in the backup file.
The method and the device for updating the audio list file based on the embodiment of the above figure 3 and playing the audio file based on the embodiment of the above figure 4 can effectively avoid adverse effects caused by disconnection of the connection between the external device and the terminal when the audio list file is read and written, ensure that the complete audio list file is stored on the external device or the terminal at any time, and ensure the integrity of the audio list file.
In the above embodiment of the present application, in the embodiment of the present application, when an external device connected to a terminal is detected, whether an audio list file corresponding to an audio file is stored in the external device is detected; when the audio list file corresponding to the audio file is not stored in the external equipment, the audio file in the external equipment is scanned, and when any one target audio file in the audio file is scanned, the target audio file is played; when the audio list files corresponding to the audio files are stored in the external equipment, the audio files stored in the external equipment are played according to the audio file information carried in the audio list files, so that when the external equipment is accessed to the terminal, the audio files can be quickly selected to be played without carrying out full-disc scanning on the external equipment, the problem that when the external equipment containing a large number of audio files is used as a song playing source, the terminal loads the audio slowly is solved, the user experience is effectively improved, and the effect of plug and play can be achieved by the external equipment.
