The AllJoyn Audio Service is a low level byte protocol for PCM/Uncompressed audio. You would need to decode and then send the decoded date over the wire. It depends on what platform you are using on how to decode the MP3. The decoding of an MP3 is outside the scope of the AllJoyn Audio Service. When you do have raw data to stream you can follow the sample applications in the git repository to see how to use the API's.

You would want to make a new MP3DataSource.cc and model it off of the WavDataSource.cc file. Then when you have an mp3 file use the MP3DataSource which would decode the file into raw PCM data.
