Event, wherein, realize broadcasting to audio, video data by self-defining class, and such inherits the player of audio, video data
Function, and this apoplexy due to endogenous wind also add the function for downloading audio, video data, the described function for downloading audio, video data
Include that first agent services to service with second agent；If monitoring control event, then call control function, by control function pair
First agent's service and second agent's service execution control operation accordingly.As can be seen here, the embodiment of the present invention can utilize
One agency service and second agent's service realize multithreading and download audio, video data, thus realize improving audio, video data and play effect
The purpose of rate.Further, the embodiment of the present invention can be corresponding to first agent's service and second agent's service execution by control function
Control operation, thus realize controlling neatly the purpose of broadcasting of audio, video data.
HTTP live Streaming (HLS) be Apple realize based on HTTP (Hypertext transfer
Protocol, HTML (Hypertext Markup Language)) Streaming transfer protocol, it is possible to achieve the broadcasting of Streaming Media.HLS is based on http protocol
Realizing, data stream is stored as continuous print, media file the longest at server end by HLS protocol, and transferring content includes two
Part, one be m3u8 file (be that a kind of of regulation in Apple's HLS protocol describes file, by text mode to media file
It is described, is made up of a series of labels)；Two is MPEG-TS (Moving Pictures Experts Group/Motion
Pictures Experts Group-Transport Stream, dynamic image Experts Group-Transport Stream) media file of form.
M3u8 file is the index file of the media file establishment for these MPEG-TS forms.Client is constantly downloaded and plays this
A little media files, are achieved that the broadcasting of Streaming Media.
In embodiments of the present invention, the first agent's service and the second agent's service that utilize self-defining apoplexy due to endogenous wind realize multi-thread
Journey downloads audio, video data, thus realizes the broadcasting of audio, video data.Fig. 2 show audio, video data in one embodiment of the invention
The flow chart of the method play, the method may comprise steps of S21-S23.
Step S21, when monitoring broadcast event, obtains first agent's service, the second agent's service preset and treats
The address of the source server of playing audio-video data.
In this step, obtain first agent's service from self-defining apoplexy due to endogenous wind and second agent services.
Step S22, utilizes first agent to service the address with source server, obtains the m3u8 literary composition of audio, video data to be played
Part, and by first agent's service, m3u8 file is resolved, obtain at least one TS file of audio, video data to be played
Source address.
Step S23, utilizes second agent to service and the source address of at least one TS file, downloads audio, video data to be played
At least one TS file, and play.
Utilize first agent to service the address with source server in step S22, obtain the m3u8 of audio, video data to be played
During file, the embodiment of the present invention is alternatively implemented as following steps A1-A2.
Step A1, is sent to first agent's service by the address of source server.
In this step, when broadcast event occurs, starting set method, set method obtains the first agent's clothes preset
The address of the source server of business, second agent's service and audio, video data to be played, the address of source server is sent out by set method
Give first agent service.
Step A2, calls the function of player, sends the request message of the m3u8 file obtaining audio, video data to be played,
Wherein, this request message carries the address of first agent's service, first agent service according to the request message received
With the address of source server, at source server, obtain the m3u8 file of audio, video data to be played.
In this step, first agent's service, according to the address of source server, sends to source server and obtains sound to be played
The request of the m3u8 file of video data；First agent services the m3u8 receiving the audio, video data to be played that source server returns
File.
In the alternative embodiment of the present invention, first agent's service obtains audio, video data to be played at source server
After m3u8 file, m3u8 file is resolved, obtain the source address of at least one TS file of audio, video data to be played.
Subsequently, the source address modification of at least one TS file is the address that second agent services by first agent's service, after being revised
M3u8 file；And then, the source address of at least one TS file is sent to second agent's service by first agent's service, and will repair
M3u8 file after changing is sent to the function of player, with by the function of player according to amended m3u8 file to the second filial generation
Reason service sends the request obtaining at least one TS file.
Thus, utilize second agent to service and the source address of at least one TS file in step S23, download sound to be played
During at least one TS file of video data, may comprise steps of B1-B3.
Step B1, calls the function of player, the m3u8 file after analytic modification, obtains the amendment of at least one TS file
After address.
Step B2, services transmission according to the amended address of at least one TS file to second agent and obtains at least one
The request of TS file.
In this step, owing to the amended address of at least one TS file is the address that second agent services, thus
Can service to second agent and send the request obtaining at least one TS file.
Step B3, second agent's service receives the request obtaining at least one TS file, according at least one TS file
Source address, download at least one TS file of audio, video data to be played.
The control event mentioned in above step S11 can include that heavy duty event, time-out are play, exited broadcasting, etc., this
Invention is not limited to this.Here it is possible to by triggering the operation of control knob (as suspended or exit button), switching program channel
Operate or restart the operation of intelligent terminal to trigger control event.
When the event of control is heavy duty event, by control function to first agent's service and second agent's clothes in step S12
Business performs to control operation accordingly, is alternatively implemented as: stopped first agent's service by control function and second agent services, and
After heavy duty, restart first agent's service and second agent services, thus the resource of two agency services is released
Put.
When control event is play or when exiting broadcasting for suspending, in step S12 by control function to first agent's service and
Second agent's service execution controls operation accordingly, is alternatively implemented as: stopped first agent's service and second by control function
Agency service, thus the resource of two agency services is discharged.
In the alternative embodiment of the present invention, control function can include stop method or pause method.Such as, catching
When receiving time-out or the trigger action of exit button, call stop method, stop method stops first agent's service and the
Two agency services.And for example, when capturing the trigger action of home key, call pause method, pause method stops the
One agency service and second agent's service.
It should be noted that in actual applications, above-mentioned all optional embodiments can be any in the way of using combination
Combination, forms the alternative embodiment of the present invention, and this is no longer going to repeat them.
