[gst-devel] bluetooth audio plugins

[Brad Midgley]

Hi

I have been working on bluetooth audio drivers with a few other 
bluetooth developers (see http://bluetooth-alsa.sf.net). Now we need to 
write them into general purpose drivers so applications like mp3 and 
videoconference software can use them.

I've been reading in the faq and plugin docs. Do you guys think it would 
be a good fit for me to write gstreamer plugins?

We want something that

  - runs entirely in userspace
  - allows multiple clients to write to the device simultaneously (using 
adder plugin or an audio server?)
  - can be written to open the bluetooth connection on demand and close 
after it's not being used
  - streams can be "split" such that eg writes go to the bluetooth 
headset but reads come from another device like a hardwired mic
  - has at least a prayer of working on embedded systems :)

There are two kinds of headsets that we're working with:
  2-way, mono, voice-quality "headset/handsfree/sco"
  1-way, compressed, stereo "a2dp"

I have been researching alsa plugins, maybe combined with the dmix 
plugin but their plugin api is underdocumented unfortunately. Gstreamer 
at least has proven it can work with network plugins and bluetooth audio 
is essentially networked streaming.

thanks guys
Brad
