UnsupportedAudioFileException: could not get audio input stream from input URL

[Raymond Domingo]

Hello,

I just tryed the media-playback-servlet example and confirmed that is
is working.

After this I changed just one line:
// java.io.File speech = new File("speech.wav");
java.io.File speech = new File("/home/raymond/Music/wav/
BrookBentonMyWay.wav");

(I tried different wav files, all playing correct on my ubuntu
firefox)
But I keep getting :

16:32:37,288 ERROR [AudioPlayer] Exception in file
file:///home/raymond/Music/wav/BrookBentonMyWay.wav

Any suggestions ?

The conference-demo also fails to work.
When I select some wave file and press Play file no music is played...
I also get the same exception:

even the provided wave file (plays in firefox but) doesn't work in the
examples like I discribed in my previous posts:

/mobicents/servers/sip-servlets/sip-servlets-examples/shopping-demo/
web/src/main/webapp/audio/OrderApproved.wav

The problem is mostly likely that we support only certain kinds of WAV files. You should convert your wav to 8khz, 16 bit, mono, PCM (uncompressed). If you dont have other software for conversion you could use Audacity. Generally follow this tutorial, but adjust the sampling rate too http://bgetutorials.wordpress.com/2007/12/02/converting-stereo-wav-to-mono-wav/

[Amit Bhayani]

As pointed out by Vladimir, in Mobicents Media Player 1.x.y the Audio Player has support only for 8khz, 16 bit mono PCM Format. However from 2.x.y we support

Linear 44100, 16bit, mono
Linear 44100, 16bit, stereo
PCMA
PCMU
Speex
GSM
and Linear like in old one


Is it possible for you to move to 2.x.y? There is no MSC API in 2.x.y but either use MGCP or JSR-309

[R.Domingo]

Thank you all for responding.

I converted some wav files and now it is working ! J

 

I’m looking forward to the 2.x.y version. I probably give it a try in future, but for now I don’t have the time to set it up L
