In obtaining current play time, reproduction time signal is generated according to current play time and sent to mobile terminal 1 10, Yi Jigen
Music regulation control is carried out according to control signal.
Mobile terminal 1 10 can be specifically the handheld mobile devices such as smart mobile phone, IPad, mainly provide the user operation circle
Face, receives the operational order of user and sends corresponding signal to wireless music router 120.Mobile terminal 1 10 and wireless sound
Can be that radio communication is carried out by modes such as bluetooth, WIFI between happy router 120.DLNA is based in the present embodiment
(DIGITAL LIVING NETWORK ALLIANCE, DLNA agreement) standard, in wireless music router
120 transplanting Platinum UPnP (Universal Plug and Play, UPnP) storehouses and madplay players are made
For DLNA/UPnP equipment ends, by the use of playout softwares such as the KuGou of mobile terminal 1 10 as DLNA/UPnP control ends, movement is eventually
Row data communication is entered in end 110 by WIFI and wireless music router 120, realizes that music wireless is played and controlled.
The code refactoring in Platinum UPnP storehouses be on the basis of the Platinum UPnP SDK that increase income, by understand and
DLNA technology relevant criterions are analyzed, the control information that mobile terminal 1 10 is transmitted are obtained, and be delivered in the form of parameter
Madplay players, realize the functions such as broadcasting, pause, the song of up/down one, F.F..Because traditional madplay players only have
The standby function of playing local audio file, it is impossible to from mobile phone terminal remote download audio file and broadcasting, it is necessary to carry out function to it
Extension.Curl storehouses are utilized in the present embodiment, by adding curl remote download moulds in madplay main body functions player.c
Block, realizes madplay players from mobile phone terminal remote download audio file function.Platinum UPnP storehouses and madplay are played
Information exchange between device, realizes that the real-time reproduction time of music and the music player interface progress bar of mobile terminal 1 10 are shown
The synchronization of time and uniformity.
Specifically, so that mobile terminal 1 10 is smart mobile phone as an example, user passes through the KuGou playout softwares in smart mobile phone
The music playlist of storage is checked, smart mobile phone is generated corresponding play signal and is sent to wireless sound by clicking on song
Happy router 120.Play signal specifically may include URL addresses of the middle pitch frequency file of mobile terminal 1 10 etc..Wireless music router
120, according to the play signal of reception, download audio file from mobile terminal 1 10 and are decoded, then control audio amplifier 130 to carry out
Music.It is appreciated that downloading song in other embodiments or in advance and being stored in wireless music router
120, the play signal that wireless music router 120 is sent according to mobile terminal 1 10 directly selects correspondence from the song prestored

Generate reproduction time signal and send to mobile terminal 1 10.Mobile terminal 1 10 shows correspondence according to the reproduction time signal of reception
Playing progress bar, realize that synchronous music is shown.Control signal also can be transmitted to wireless music router 120 in mobile terminal 1 10,
Wireless music router 120 carries out music regulation according to control signal and controlled, such as play out, suspend, up/down one is bent,
The function controls such as F.F..
In one of the embodiments, wireless music router 120 carries out corresponding operating according to the signal of reception, specific logical
Cross the control letter of acquisition mobile terminal 1 10 write on Platinum UPnpP SDK Media Render media player modules
Breath and parameter information function GetStateVariableValue () are carried out.The data structure wherein related generally to is as follows：
typedef struct StateVariableValue{
NPT_String metadata；
NPT_String uri；
NPT_String currenturi；
NPT_String target；
Char*action；
}StateVariableValue。
Structure includes audio file header information, audio file URL address lists, current played file URL addresses, progress
Bar drag target time value and current action.
The idiographic flow of GetStateVariableValue () function is as follows：
GetAVTransportmetadata () audio file header information
GetAVTransportURI () url list
GetAVTransportTargetTime () progress bar drag target time
The current URL addresses of GetAVTransportCurrentTrackURI ()
GetCurrentTransportActions () is acted
Platinum UPnP define PLT_MediaRenderer classes, establish the control framework to equipment.PLT_
MediaRenderer is defined as follows：
class PLT_MediaRenderer
{
public:
Virtual NPT_Result OnNext ()=0；
Virtual NPT_Result OnPause ()=0；
Virtual NPT_Result OnPlay ()=0；
Virtual NPT_Result OnPrevious ()=0；
Virtual NPT_Result OnSeek ()=0；
Virtual NPT_Result OnStop ()=0；
}
Control process only needs to directly invoke madplay players, adds GetStateVariableValue () function and obtains
The relevant parameter taken, such as in order to realize playing function, the main code added in OnPlay () function is as follows：
Sprintf (cmd_buffer, " madplay-v-o wav:- %s | aplay＆ ", uri.GetChars ())；
System(cmd_buffer)；
In order to realize fast forward/back function, following main code is added in OnSeek () function：
Sprintf (cmd_buffer, " madplay-v-s%s-owav:- %saplay＆ ", target.GetChars
(), uri.GetChars ())；
System(cmd_buffer)；
Uri in above-mentioned code, target are variate-value, can be obtained by GetStateVariableValue () function.
In the present embodiment, when music is played in the music player software control in mobile terminal 1 10, madplay players
It is responsible for downloading audio file from mobile terminal 1 10, and stores into temporary file Filename, defined in madplay player
Player pointers by reading temporary file, obtain played file information, and played out after MP3 decoding.
Madplay players have write download_file () function in its main body function play_one (), realize
Wireless downloading function.The idiographic flow of download_file () function is as follows：
Curl=Curl_easy_init () initialization of variable；
Fp=fopen (outfilename, " wb ") defines fp file pointers；
Curl_easy_setopt (curl, CURLOPT_URL, url) processing url addresses；
Curl_easy_perform (curl) url data is downloaded；
Curl_easy_setopt (curl, CURLOPT_WRITEFUNCTION, write_data) processing is received
Downloading data；
Curl_easy_setopt (curl, CURLOPT_WRITEDATA, fp) sets fp to be exported for stream data flows
Target；
Curl_easy_cleanup (curl) releasing memory space.
When wireless music router 120 calls " madplay-v-owav:- %s | aplay＆ ", uri.GetChars ()) "
When playing music, a series of variables are first initialized in audio download phase libcurl storehouses, are then handled by uri.GetChars
()) obtained URL addresses and start to download, the data of download flow through the file adjusted back and pointed to file pointer fp after processing.
In order to ensure real-time that the music player software interface time schedule bar of mobile terminal 1 10 shows, it is necessary to the cycle
