Hi

I tried but Full Duplex application do not work. and actually i want to play audio from streaming server(using URL) i am able to play local file.

so i want to use RSocket for store streaming data into buffer and after send data for play, but i don't know how i can use RSocket with Audio Streaming.

"Audio Streaming" is a complex thing.
Check if CMdaAudioPlayerUtility::OpenUrlL happens to do what you need.
Otherwise you can go for RTP/RTC API-s from the plug-in pack: http://wiki.forum.nokia.com/index.php/SDK_API_Plug-in

Hi

Thanks for replay.

I am doing but get -5 error, so i tried to read data using RSocket but do not know that how i can read data from following URL.

iAuPlayUtil->OpenUrlL(_L("rtsp://rmlive.bbc.co.uk/bbc-rbs/rmlive/ev7/live24/radio1/live/r1_dsat_g2.ra"));

I get it following snippets but how i can use with above code.

Code:


User::LeaveIfError(iSocketServer.Connect());
        //CleanupClosePushL(iSocketServer);
        User::LeaveIfError(iListener.Open(iSocketServer,KAfInet,KSockStream, KProtocolInetTcp));
                
        User::LeaveIfError(iListener.SetLocalPort(80));
        //TInetAddr iAddress(KInetAddrAny,2345);
        //User::LeaveIfError(iListener.Bind(iAddress));
                
        User::LeaveIfError(iListener.Listen(1));
        //TRequestStatus status;
        TBuf8<256> buffer;
        iSocket.Open(iSocketServer);
        iListener.Accept(iSocket, iStatus); 
        
        User::WaitForRequest(iStatus);
        
        TPtr8 gDataPtr(NULL,0);
        TUint32 msglen;
        TUint8 *buf=new TUint8[msglen];
        gDataPtr.Set(buf,0,msglen);
        iSocket.Read(gDataPtr,iStatus);
        
        User::WaitForRequest(iStatus);

Oops, you are right. That is a known issue. However you will find a possible workaround if you search for OpenUrlL in the Wiki.

You can still consider searching for OpenUrlL in the Wiki...

Hi

I searched but result is:

In following link says that : CMdaAudioPlayerUtility::OpenUrlL() cannot be used for opening audio files or streams for playback.

http://wiki.forum.nokia.com/index.ph...ot_implemented

and this link show the code implementation: that i implemented in my application but void MapcInitComplete(TInt aError, const TTimeIntervalMicroSeconds &aDuration) return aError = -5.

http://wiki.forum.nokia.com/index.ph..._Playback_APIs.

It is Ok, I meant this article. However it also suggests a solution, have you checked if it is suitable for your needs?

**SymbianTH** · 2009-05-20, 14:42

Yes

give error -5 (-5 = KErrNotSupported)

I want to play audio file in following way
iAuPlayUtil->OpenUrlL(_L("rtsp://rmlive.bbc.co.uk/bbc-rbs/rmlive/ev7/live24/radio1/live/r1_dsat_g2.ra"));

Just to make sure: iAuPlayUtil is CVideoPlayerUtility, is not it?
