Have a query how the bluez will be identifying the player and respond the correct metadata or attributes. Based on the following blog, Is this supported in pulseAudio currently which version of player or pulseAudio i should be using for handling this. http://jprvita.wordpress.com/ The proposed approach to implement this project is to have PulseAudio intermediating data exchange between media players and bluetoothd. For each audio stream going to a bluetooth audio sink it would listen to TrackChange and StatusChange signals coming from the application generating the stream going to that device and send this information to the remote peer through AVRCP calling a method exposed on bluetoothd?s org.bluez.Control interface. This integration could latter be extended for basic player controls, having PulseAudio to listen to bluetoothd signals and call methods on media players MPRIS interfaces to trigger the matching action. Also, a similar approach could be modeled for adding content browsing capability, as defined by AVRCP 1.4 specification. Thanks & Regards Rohit Sharma
