Description
Technical field
The present invention relates to multimedia technology field, particularly relate to a kind of audio data play method and device.
Background technology
Along with the development of multimedia technology, user listens to music online by mobile device to be become many used for mobile terminal
The selection at family.The application scenario such as live online for audio frequency, directly transmits complete AAC sound to the client being connected with server
Although frequency is according to mobile client can be made directly to play audio frequency, but client is not necessarily required to listen to complete whole section audio,
Such as many users terminate to listen to this section audio owing to loseing interest in it after often hearing out beginning one section audio, it is clear that complete
The transmission of whole AAC voice data can cause the wasting of resources, and the transmission of big data quantity easily produces data and the problem such as substitute.
For solving the problems referred to above, in current this area, develop streaming media solutions based on http protocol, i.e. HLS
(HTTP Live Streaming).In HLS technology, Web server provides close to real-time audio/video flow to client.But make
It is the http protocol of the standard used during with, so at this moment, as long as using the technology of HLS, just can be at common HTTP
Application on program request and live is directly provided.This technology ultimate principle is video file or audio stream to be cut into small pieces and sets up
Index file (M3U8), such as, by the index of the data of Advanced Audio Coding format (Advanced Audio Coding, AAC)
Address sends with the form of M3U8 file, or with the form of M3U8 file, the voice data of TS form is sent to client.
But, it is currently based on the player of Android system exploitation, single Advanced Audio Coding format (Advanced can only be supported
Audio Coding, AAC) data playback and the M3U8 file of TS form, it is impossible to support AAC form M3U8 file.
Summary of the invention
The present invention provides a kind of audio data play method and device, and being used for solving Android system player cannot play
The problem of the M3U8 file of AAC form.
The present invention provides a kind of audio data play method, for client, including:
The request downloading voice data is sent to server；
Receive multiple M3U8 slicing files that server is sent；Described M3U8 slicing files have recorded a section high of correspondence
The index address of level audio coding formats AAC voice data；
One section of AAC audio frequency that each M3U8 slicing files is corresponding is parsed from each described M3U8 slicing files received
The index address of data；
According to the index address of multiple AAC voice datas that parsing obtains, obtain a section stored in each index address
AAC voice data；
The multistage AAC voice data got is played out in the form of streaming.
Some beneficial effects of the embodiment of the present invention may include that

Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are illustrated, it will be appreciated that preferred reality described herein
Execute example be merely to illustrate and explain the present invention, be not intended to limit the present invention.
Fig. 1 is the flow chart of a kind of audio data play method in the embodiment of the present invention.As it is shown in figure 1, the method includes
Following steps S101-S104:
S101: send the request downloading voice data to server.
S102: receive multiple M3U8 slicing files that server is sent；Wherein, each M3U8 slicing files have recorded this
The index address of one section of AAC voice data that M3U8 slicing files is corresponding.
Wherein, AAC voice data is encapsulated into the mode of M3U8, and be encapsulated into the mode of M3U8 with TS similar, the most superfluous
State.
S103: parse one section of AAC sound that each M3U8 slicing files is corresponding from each M3U8 slicing files received
The index address of frequency evidence.
S104: according to the index address of multiple AAC voice datas that parsing obtains, obtains storage in each index address
One section of AAC voice data.
S105: the multistage AAC voice data got is played out in the form of streaming.
Preferably as an optional embodiment, local player can provide a user with streaming broadcast button, step S104
And between S105, may also include that the streaming playing request being received user's input by the streaming broadcast button of local player.Then
With specific reference to the streaming playing request received in step S105, the multistage AAC voice data got is carried out in the form of streaming
Play.
The audio data play method that the present invention provides, server is by being sent to the M3U8 slicing files of AAC form
Client, thus client can obtain in index address deposit by parsing the index address in the M3U8 slicing files received
The AAC voice data of storage, and the AAC voice data got is played out in the form of streaming.The method can solve the problem that
The problem that Android system player cannot play the M3U8 file of AAC form, it is possible to make client especially Android system client
Hold direct audio stream plays, play simple and convenient, compatible strong, applied widely.
Preferably, in each index address that step S104 gets, one section of AAC voice data of storage includes that order is known
Other code, then as in figure 2 it is shown, step S105 can comprise the following steps S201-S202:
S201: the multistage AAC voice data identification code in their order order got is preserved in the buffer, forms audio frequency
Stream.
Such as: if successively from received server-side to 3 M3U8 slicing files in S102, resolve successively through S103 and obtain this
The index address of 3 M3U8 slicing files, through S104 get successively the 1st section of AAC voice data, the 2nd section of AAC voice data,
3rd section of AAC voice data, wherein, the sequential identification codes of the 1st section of AAC voice data is 1, the order of the 2nd section of AAC voice data
Identification code is 3, and the sequential identification codes of the 3rd section of AAC voice data is 2, then according to " the 1st section of AAC audio frequency number in this step S201
According to, the 3rd section of AAC voice data, the 2nd section of AAC voice data " order these 3 sections of AAC voice datas preserved formed in the buffer
Audio stream.
S202: play the AAC voice data preserved in caching in the form of streaming.
Wherein, AAC voice data is saved in the buffer, the most directly due to S201 identification code the most in order order
From caching, the voice data of reading and saving is play in the form of streaming.
For live voice data, client need not download also cannot once download complete program
Voice data, server end edge stores the AAC voice data of nearest preset duration and generates M3U8 file, and client obtains with regard to limit
AAC voice data in the index address that several M3U8 slicing files that server is newly generated are corresponding, and identify according to order
These AAC voice datas of up-to-date acquisition are stored in caching by code.
In this embodiment, the multistage AAC voice data got is preserved in the buffer according to its sequential identification codes order,
Directly form the correct audio stream of the voice data that client is asked, it is to avoid the different sections caused due to network transmission delay
The order dislocation of AAC voice data, further ensures the accuracy rate of audio transmission and broadcasting.
Preferably, in another embodiment, step S102 may also include that and receives each M3U8 burst that server is sent
The video file that AAC voice data that file is corresponding is corresponding.In this embodiment, step S105 is specifically by every section of AAC audio frequency number
According to the video file synchronization broadcasting corresponding with this section of AAC voice data.When being embodied as, can according to every section of AAC voice data and
The timestamps of video file etc. are for indicating the parameter of reproduction time to carry out the synchronization of Voice & Video, and here is omitted.
Below by specific embodiment, the audio data play method that the embodiment of the present invention provides is described.
