Hi all

I am hacking the bluez audio coding.
I saw that bluez implement audio sink profile in remote device.
Is there any ppl working on audio source profile?

And there is a gstreamer sbc decoder, but how can i create the audio stream
from remote side?

I've been working in the audio sink implementation (...Audio.Source interfa=
ce),
but because of the changes we are now doing for bluez 4.0 I left that
unfinished.

The code is available in my branch audio-source:
http://git.infradead.org/users/vudentz/bluez-utils.git?a=3Dlog;h=3Drefs/hea=
ds/audio-source

I was already able to configure streams between 2 linux boxes, but
there is no plugin to
handle the streams yet.

This task is also available in gsoc page, so any student interested may app=
ly:

Hi Luiz

Thanks, i found the audio source code. But when i compile the source, it
seems there are missing files. I search over the repository and git
snapshot, i could not find gsta2dpbin.c/h. but audio/Makefile refer to these
two files.

mv -f .deps/libgstbluetooth_la-gstrtpsbcpay.Tpo .deps/libgstbluetooth_la-
gstrtpsbcpay.Plo
make: *** No rule to make target `gsta2dpbin.c', needed by
`libgstbluetooth_la-gsta2dpbin.lo'.  Stop.

Regards,
Mike,Lee

Hi there,

My bad, I forgot to remove it from Makefile.am, for instance you can
do it in order
to compile. I will fix it when I resync with marcel's tree.

Hi Luiz

I del the entry and try to use it. My setup like this
Nokia mobile phone (src) -> Thinkpad notebook (sink)

I make one more change on a2dp.c(1263) in order to make this work.
avdtp_get_seps(session, !type,....  =>  avdtp_get_seps(session, type...

And when i successfully connected to my notebook and play mp3 file in
mobile,
i find that my pc receive discover cmd again and again without play out
anything.
The mobile player seem to skip every songs.

by hcidump, the Audio Sink(PC) reply with "ACP SEID2 - Audio Sink(InUse)".Do
you have any idea on this?
