I’m wondering if it’s possible to use Jingle to stream an MP3 file from one user to another. I’ve had a look at the demo code for Jingle, and I have not been able to fathom how I can change the audio input from the microphone to an MP3 file. Is this possible? Additionally, I can run the demo code and initialise a connection but an error occurs on both the sender and receiver:
java.lang.NullPointerException
RAW CAND
RAW CAND
Track 0 is set to transmit as:
gsm/rtp, 8000.0 Hz, Mono, FrameSize=264 bits
Failed to realize: com.sun.media.ProcessEngine@530cf2
Cannot build a flow graph with the customized options:
Unable to transcode format: LINEAR, 44100.0 Hz, 16-bit, Stereo, LittleEndian, Signed
to: gsm/rtp, 8000.0 Hz, Mono, FrameSize=264 bits
outputting to: RAW/RTP
Error: Unable to realize com.sun.media.ProcessEngine@530cf2
Can anyone help?
