AVRCP 1.4 : Future on Target Role

Hi All,

I have been looking at AVRCP 1.4 in BlueZ and intending to
enhance/develop this profile for the target role. I have been
following the discussion initiated by Sander van Grieken earlier last
month, and as I understand, they are premitive and has scope for
further enhancements.

In the current BlueZ implementation, control-api.txt mentions few
methods e.g. SendVendoeDependent, ChangePlayback..., that are not
referred/implemented in the code, or I may be unable to find at right
place.
Further, there are some more AVRCP 1.4 TG specific Notify and Browsing
commands that can be added.

I am willing to define some preliminary interface APIs for Target
Media Applications to register itself with BlueZ, and would come back
with some idea proposal for your suggestions on improvements.

I am keen to receive your feedback with some ideas and thoughts to put
my effort in right direction.

Question:
Is anyone working on AVRCP 1.4 Target role profile development?

Regards,
Shivendra
