Detailed Description
With the increasing maturity of car networking technology, playing network radio on cars has become a trend. When the network radio plays audio, the network radio acquires audio data through the network and plays the audio data. The playing address can be accessed specifically, and then audio data can be acquired. The vehicle often can pass in and out the relatively poor region of network signal in the course of traveling, for example the vehicle can pass in and out the tunnel, and when the vehicle was in the tunnel, the network radio just can't visit the broadcast address, and then can't obtain audio data, just also can't normally broadcast the audio frequency. After the network exits the tunnel, the network radio can access the playing address, and then continue to acquire and play the audio data.
Therefore, under the condition of network interruption, the network radio stops playing audio, and when the network is recovered, the network radio recovers playing audio, and when the vehicle frequently enters and exits an area with poor network signals, the network radio can continuously play audio, so that poor user experience is caused. Moreover, the contents played by the network radio generally have certain real-time performance, such as news programs.
In order to solve the technical problem, the scheme provided by the application comprises an audio playing method, wherein an audio clip with the total playing time as a storage time threshold is downloaded and stored to the local when the network is normal, the audio clip stored in the local can be acquired and played under the condition of network disconnection, and when the network disconnection time is greater than the storage time threshold, the starting time for downloading the audio clip can be determined according to the current time and the storage time threshold after the network is recovered. As long as the network disconnection time length is less than or equal to the storage time length threshold value, the user does not feel network disconnection, and the experience of the user is improved. When the network disconnection time length is larger than the storage time length threshold value, the starting time of playing the audio clip can be determined according to the current time and the storage time length threshold value when the audio is played again, and the real-time performance of audio playing is guaranteed.
Fig. 1 is a flowchart illustrating an audio playing method according to an exemplary embodiment of the present application.
As shown in fig. 1, the audio playing method provided by this embodiment includes:
The method provided by the application can be executed by an electronic device with computing capability, for example, an in-vehicle device provided in a vehicle, and the in-vehicle device can download an audio clip and play the audio clip.
The scheme provided by the application can be applied to a network radio, and the network radio can be arranged in electronic equipment, such as vehicle-mounted equipment. The network radio can be divided into two parts of a downloader and a player. The downloader can download and store the audio clip locally, specifically, the audio clip downloaded by the downloader can be stored in a reception pool, and the reception pool is a component of the downloader. The player can acquire the audio clips from the radio reception pool of the downloader and play the acquired audio clips.
The audio clip downloaded by the downloader may be a Transport Stream (ts) file, the ts file may be a playable voice file, and one ts file may be an audio clip.
Further, a background server of the network radio can acquire the radio station data from the cloud and slice the radio station data. For example, it is possible to set one ts file every 5s on average, and record information of an audio piece by an m3u8 file, for example, 10 ts files by an m3u8 file. Where the m3u8 file is a list file.
Specifically, the m3u8 file includes a download path of the ts file, station information, and time information. Each ts file has a time length of 5 s.
The downloader obtains the m3u8 file from the background server, analyzes the ts list file in the m3u8 file, and orderly downloads the ts file. Specifically, the audio clips may be downloaded in time sequence according to the time information of the audio clips.
The time information refers to the time attribute of the audio segments, including the start time, the end time, and the time length of each audio segment. An audio segment whose time information is continuous means that the end time of the previous audio segment is the start time of the following audio segment.
The audio clip downloaded by the downloader can be stored in a radio pool in the downloader.
The storage duration threshold refers to the duration of the maximum audio frequency storable in the reception pool. For example, the storage duration threshold may be set to be two minutes, and assuming that the duration of each audio clip is 5s, the reception pool may store 24 audio clips at maximum, and the sequence numbers may be 10001-10024 in chronological order.
Further, the downloader may stop downloading after the reception pool is full of 24 audio clips.
And step 102, sequentially acquiring and playing the stored audio clips under the condition of no network.
Specifically, the player of the network radio sequentially acquires and plays audio clips from the radio pool of the downloader, acquires and plays audio clips with the time being before first, and acquires and plays audio clips with the time being after later.
Further, under the condition that no network exists, the player can still obtain the pre-downloaded audio clip and play the audio clip, so that under the condition that no network exists, the scheme provided by the disclosure can still normally play the audio with the storage duration threshold.
In actual application, if no network exists, the downloader in the scheme can also send an HTTP request to the background server every 10s, if the background server responds to the HTTP request, the network can be connected, and if the background server does not respond to the HTTP request, it indicates that the network cannot be connected, and the downloader continues to send the HTTP request to the background server.
Further, under the condition of a network, the player acquires and plays an audio clip from the reception pool, the corresponding audio clip in the reception pool is deleted, and the downloader downloads a new audio clip from the background server and then the last audio clip in the reception pool and stores the new audio clip in the reception pool, so that the length of the audio in the reception pool is maintained at the storage duration threshold.
And 103, when the network disconnection time length is greater than the storage time length threshold value, if the network is recovered, acquiring the current time, and determining the starting time of the audio clip needing to be downloaded according to the current time and the storage time length threshold value.
Specifically, if the network disconnection time length is less than the storage time length threshold value, the downloader can continue to download the audio clip to supplement the data in the reception pool after the network is recovered. And when the network is recovered, the data in the reception pool is not played completely, so that the player can continuously acquire and play the audio clip from the reception pool in the period from the network disconnection to the network recovery, the playing state of the player cannot be interrupted, the user cannot perceive that the network is disconnected, and good user experience is further brought to the user.
Further, if the network disconnection time length is greater than the storage time length threshold value, the network is still not recovered when the player plays all the data pre-stored in the reception pool, and under the condition, the player cannot acquire the next audio clip to be played, so that the electronic equipment can display prompt information without the network.
In practical application, if the network disconnection time length is greater than the storage time length threshold value, the electronic equipment can continue to download the audio clip when the network is recovered. In this case, the electronic device may first obtain the current time, and determine the start time of the audio segment to be downloaded by combining the current time and the storage duration threshold. To ensure timeliness of the audio that continues to be downloaded.
The scheme provided by the disclosure can be applied to the network radio, and the content played by the network radio has certain real-time performance, for example, news programs are played, and the timeliness of the audio is very strong. If the content played before the network is disconnected is continuously downloaded after the network is recovered, the real-time performance of the downloaded audio content is poor. According to the scheme provided by the disclosure, the starting duration of the audio clip downloaded next can be determined according to the current time, so that the audio content conforming to the current time can be downloaded, and the audio content with better timeliness is provided for the user.
Assuming that the storage time length threshold is two minutes, if the network disconnection time length exceeds two minutes, acquiring the current time after the network is recovered, and determining the starting time of the audio clip needing to be downloaded according to the current time and the storage time length threshold.
In one embodiment, the current time may be subtracted by the storage duration threshold to obtain the start time of the audio segment to be downloaded. For example, if the score is 1/29/2021, 15/13, the network is recovered, the audio clip is downloaded at 15/11/1/29/2021, and after 5 audio clips are downloaded, the recovery play operation is performed.
The step 101 is continuously executed according to the determined starting time, that is, the step of downloading and storing a plurality of audio segments with continuous time information is continuously executed according to the starting time.
The application provides an audio playing method, which comprises the following steps: downloading and storing a plurality of audio clips with continuous time information, and stopping downloading the audio clips when the total playing time of the stored audio clips reaches a storage time threshold; sequentially acquiring and playing the stored audio clips under the condition of no network; when the network disconnection time length is greater than the storage time length threshold value, if the network is recovered, acquiring the current time, and determining the starting time of the audio clip needing to be downloaded according to the current time and the storage time length threshold value; and continuing to execute the step of downloading and storing a plurality of audio segments with continuous time information according to the starting time. According to the audio playing method, the audio clip with the total playing time as the storage time threshold is downloaded and stored to the local when the network is normal, the audio clip stored in the local can be obtained and played under the condition of network disconnection, and when the network disconnection time is greater than the storage time threshold, the starting time for downloading the audio clip can be determined according to the current time and the storage time threshold after the network is recovered. As long as the network disconnection time length is less than or equal to the storage time length threshold value, the user does not feel network disconnection, and the experience of the user is improved. When the network disconnection time length is larger than the storage time length threshold value, the starting time of playing the audio clip can be determined according to the current time and the storage time length threshold value when the audio is played again, and the real-time performance of audio playing is guaranteed.
Fig. 2 is a flowchart illustrating an audio playing method according to another exemplary embodiment of the present application.
As shown in fig. 2, the audio playing method provided by this embodiment includes:
The background server of the network radio station can cache one radio station audio data from the cloud end and slice the radio station audio data to generate one audio clip every 5s, and the audio clip can be in a ts format. The backend server may also record audio clips through an audio file list, which may be an m3u8 file, assuming 10 ts files are recorded at a time.
The network radio comprises a downloader and a player, wherein the downloader downloads and stores the audio clips to the local, and the player acquires the audio clips from the downloader and plays the audio.
A downloader in the network radio acquires an audio file list from a background server, wherein the audio file list is a file for recording audio clips and comprises a download address and time information of each audio clip. The downloader can parse the audio file list and acquire the download address and the time information of each audio clip.
The download address in the audio file list indicates that each audio clip corresponds to one download address, and the downloader can download the corresponding audio clip according to the download address. The time information in the audio file list means that each audio clip corresponds to a time information, and the time information includes the start time, the end time and the time length of the corresponding audio clip. Each audio clip has a corresponding download address and time information in the audio file list.
In another embodiment, the audio file list further includes station information for each audio clip.
Specifically, the audio file list may further include radio station information of each audio clip, and the downloader may acquire the audio file list from the background server and may acquire the radio station information of each audio clip after parsing the audio file list.
Further, each audio clip has a corresponding download address, time information and station information in the audio file list.
And 202, downloading and storing the audio clip according to the downloading address and the time information in the audio file list.
Specifically, the downloader parses the audio file list, may obtain a download address and time information of the audio file, may download each audio clip according to the download address and time information, and stores the downloaded audio clip in a reception pool in the downloader.
In another embodiment, the download address of each audio clip is sequentially accessed according to the time information of each audio clip; each audio clip is retrieved and stored in turn from the location pointed to by the download address.
Specifically, according to the time information in the audio file list, the download addresses of the corresponding audio clips are sequentially accessed according to the continuous time sequence, each audio clip is obtained from the position pointed by the download address, and the audio clips are stored in the sound receiving pool. Wherein, the sequential time sequence means that the end time of the previous audio segment is the start time of the next audio segment.
And step 203, when the total playing time of the downloaded audio clips reaches the playing time threshold, playing the audio clips one by one according to the time information of each audio clip.
The playing time threshold refers to a threshold of the total playing time of the audio clips stored in the reception pool, and the playing time threshold is a preset value, for example, the playing time threshold may be set to 25s, and if the time of each audio clip is 5s, the playing time threshold is reached when 5 audio clips are stored in the reception pool.
Specifically, when the network is normal, the downloader can download all the audio clips in the audio file list and store the audio clips in the reception pool, when the total playing time of the audio clips stored in the reception pool reaches the playing time threshold, the downloader sends a message to the player, the player acquires the audio clips in the reception pool according to the time information of each piece of audio information and according to the continuous and sequential time sequence, and plays the audio clips one by one after each acquisition. The audio clip obtained by the player is deleted from the sound reception pool.
And step 204, after the audio clip is played, continuing to download the audio clip, so that the total playing time of the stored and unplayed audio clip reaches the storage time threshold.
The storage duration threshold refers to the duration of the maximum audio frequency storable in the reception pool. The storage period threshold is set in advance, assuming that the storage period threshold is set to 2 minutes. Then if the duration of each audio clip is 5s, a maximum of 24 audio clips can be stored in the reception pool.
Specifically, when the network is normal, the downloader downloads and stores the audio clips into the reception pool in order, and the reception pool is full of 24 audio clips, and when the player plays an audio file, the reception pool deletes one audio clip, and the corresponding downloader downloads another audio clip into the reception pool, so that 24 audio clips are always stored in the reception pool.
And the playing time length threshold is smaller than the storage time length threshold.
The storage duration threshold refers to the duration of the maximum audio frequency storable in the reception pool. The playing time length threshold refers to a threshold of the total playing time length of the audio clips stored in the reception pool, and when the playing time length threshold is reached, the player obtains the audio clips from the reception pool and plays the audio clips. Therefore, if the playing duration threshold is greater than the storage duration threshold, the voice clip cannot be played.
And step 205, stopping downloading the audio clip when the total playing time of the stored audio clip reaches the storage time threshold.
Step 205 is similar to the implementation manner and principle of the related content in step 101, and is not described again.
And step 206, under the condition that no network exists, sequentially acquiring audio clips corresponding to the radio station information being played according to the radio station information being played and the radio station information included in the audio file list, and playing the acquired audio and video clips.
Specifically, the network radio includes more than one radio station, and if the network is disconnected, the radio station information of the audio clip stored in the radio pool is the radio station information of the audio clip currently being played. If the user does not change the radio station when the network is disconnected, the player can accordingly obtain the audio clip from the radio pool and play the audio clip.
In one embodiment, if the station is changed when the network is disconnected, no corresponding audio clip will be playable, at which point the network radio will load a turn.
In another embodiment, audio segments of multiple radio stations may be cached, and further, in the absence of a network, even if a user switches a radio station being played, the electronic device may obtain a corresponding audio segment and play the audio segment.
And step 207, when the network disconnection time length is greater than the storage time length threshold value, if the network is recovered, acquiring the current time, and taking the time obtained by subtracting the storage time length threshold value from the current time as the starting time of the audio clip needing to be downloaded.
Specifically, assuming that the storage time threshold is 2 minutes, when the network disconnection time is longer than 2 minutes, the player has no network after playing 24 audio clips stored in the reception pool, and at this time, the network radio may load a turn.
When the network is restored, the electronic device may obtain the current time, for example, the current time is 13 minutes from 1 month, 29 days and 15 days of 2021, and take the current time minus two minutes, that is, 11 minutes from 1 month, 29 days and 15 days of 2021 as the starting time for downloading the audio clip.
In step 208, the start audio segment with the same time information as the start time is downloaded and stored.
Specifically, for example, the 15 th day 11 of 29 th day 1/29 in 2021 is taken as the starting time of the audio clip to be downloaded, the downloader parses from the audio file list and finds the corresponding audio clip whose time information is the starting time and this time, and downloads and stores this audio clip as the starting audio clip.
In this case, the audio clip acquired by the electronic device may be an audio clip corresponding to the current time, and the electronic device may be further enabled to play the latest audio content after the network is restored.
And step 209, sequentially downloading and storing other audio clips with time information later than the starting time and continuous time information.
Specifically, starting from the initial audio clip, the downloader sequentially downloads and stores the audio clips into the reception pool according to a continuous time sequence. When the reception pool is full of 5 audio files, the downloader sends a signal to the player, the player sequentially acquires and plays the audio files from the reception pool, and one audio file is deleted from the reception pool every time one audio file is played. The downloader downloads the audio files to the sound reception pool, and stops downloading when the number of the audio files stored in the sound reception pool is 24, and the 24 audio files stored in the sound reception pool are always kept.
In another embodiment, when the network disconnection time length is less than or equal to the storage time length threshold value, if the network is recovered, the latest time information in each stored audio clip is determined.
Specifically, assuming that the storage time threshold is 2 minutes, when the network disconnection time is less than or equal to 2 minutes, the player does not play 24 audio clips stored in the reception pool, and the network is recovered. If the 24 audio clips in the reception pool are 10001-10024 respectively according to the time sequence, assuming that the 20 th audio clip has been played at this time, the network replies, and the downloader determines that the latest time information in each stored audio clip is 10024.
And determining the starting time of the next audio clip to be downloaded according to the latest time information.
Specifically, if the downloader determines that the latest time information included in each stored audio clip is 10024, the downloader continues to download the audio clip with the start time of the audio clip No. 10025 as the start time from the background server.
And continuing to execute the step of downloading and storing a plurality of audio segments with continuous time information according to the starting time.
Specifically, if it is determined that the start time of the 10025 th audio clip is the start time, the downloader continues to download 24 full audio files from the 10025 th audio clip and stores the audio files in the reception pool, and the iteration is continued.
Fig. 3 is a process diagram of an audio playing method according to an exemplary embodiment of the present application.
As shown in fig. 3, the downloader obtains the audio file list from the background server, parses the audio file list, obtains the time information of the audio clip, obtains the current time, compares the time information of the audio clip with the current time, and downloads the audio clip two minutes ago by the downloader, that is, downloads the audio clip two minutes ago by the current time according to the time continuity and the time sequence and stores the audio clip into the reception pool.
When the download is full of 5 audio clips, the audio clips are continuously downloaded, and a signal is given to the player, and the player acquires the audio clips from the downloader and plays the audio clips. And when the radio reception pool is full of 24 audio clips, the corresponding downloader stops downloading the audio clips, so that the audio clips stored in the radio reception pool are kept at 24.
When the network is normal, the above operations are continued. When the network is disconnected, the network is detected by adopting a heartbeat continuous detection method, specifically, the downloader sends an HTTP request to the background server every 10s, if the background server responds to the HTTP request, the network can be connected, if the background server does not respond to the HTTP request, the situation that the network cannot be connected is indicated, and the downloader can continuously send the HTTP request to the background server. When the network is restored, the above operation is continued from the acquisition of the audio file list.
