a2dp on maemo/nokia770
Hey
Any nokia developers hanging out here?
I would like to get A2DP audio working with the 770. The codec would perform faster/better if it was a proper dsp task but that's beyond the scope of a volunteer effort.
Is nokia working on it?
Brad

Probably at a guess they are in preparation for the Internet Table 2006 release so BT Headsets can be supported. They have been doing a fair amount of other work around some of the core infrastructure of BT for things like integration with dbus so they may not be at the BT-Audio stage yet. Its intersting to note thought that on their OS Website (here http://opensource.nokia.com/) they mention they are going to be releasing Affix (a bt protocol stack for linux)shortly.

the Affix stack (affix.sf.net) has been around since November 2001.

Currently we are working on basic hs support. A2DP is not yet under focus. However dsp-style approach is one of the possibilities.
Feel free to send any wishes, suggestion and ideas regarding bt audio support. We'll keep them in mind when we do decisions and plans.

since I've already seen Nokia phones with A2DP Source capabilities, the question is now is this a bought solution or is developed inside Nokia. If it is developed inside Nokia you might wanna share it or help us out to get our SBC in shape and really good and fast.
The Nokia 770 is using a TI chip and basically nobody of us has real experiences with these chips. I have seen them in an iPAQ and now the 770, but that's it. Do you think Nokia is willing to donate some of the TI development kits to BlueZ? Especially the SCO and eSCO stuff needs a lot of testing and I would prefer to do it with an i386 or x86_86 based system.

Marcel

I wouldn't hold my breath to see that happening. Whan is the situation with current SBC? What is missing? Is performance optimal? I have followed discussions about it and there seems to be fixed point implementaion allready but that has poor quality compared to floating point version.

I'll try to arrange something.

this is what I know. Bard of course would have more details since I haven't done any SBC related work for some time. I am not a codec expert and so not really helpful, but I still think that fixed point is the only way to go. Some people at the UPFs acknowledge this, but of course without any details about actual code.

This would be great, thanks.
