Hi

Can someone tell me which of these files shouldn't be in our btsco cvs module?

acinclude.m4
aclocal.m4
config.status
configure
configure.in
Makefile
Makefile.am
Makefile.in
missing
mkinstalldirs

I know some projects even make you generate "configure" but I'm not sure I want to go that far.

btw, I added a sort of placeholder "a2play.c" to the project for sending preencoded audio to an a2dp player. I want to make sure our autoconf mess is cleaned up before putting it in the build.

Brad

look at the BlueZ libs and utils CVS repository. I spent quite some time to clean up this autoconf/automake mess. Basically what I do is:

	./bootstrap
	./configure
	make
	==> modify files, compile again, test etc.
	make maintainer-clean

This keeps your CVS repository clean.

This is great. Does it work for you already. Do you hear any sound?

Regards

Marcel

no, it's pretty early yet.

what do you suggest for packing bits together in a portable way before putting them on the wire? is there some code somewhere that you can point to that works in userspace?

Yeah, I guess I just needed to read up more.

I'm going to be assembling parts of frames like the media packet header. I started looking at l2cap_build_cmd to see how you do it in kernel space. I see htobs() is the equivalent of __cpu_to_le16 for 16-bit values and I see the __attribute__ ((packed)) directives that result in a packed struct that can be copied byte for byte into the buffer. I think I'm good to go.

I'll probably be running the naming for some of the structures and members by you to see if they're ok to eventually go into the bluetooth headers.

please don't think about any kernel part at this time. It is not the time to do any kernel work. The l2cap_build_cmd() is by the way the wrong place to look at, because AVDTP is L2CAP payload.

If we get a program that can play pre-encoded SBC files on an A2DP headphone then this is a good start. This program should be in userspace first so we can learn through it. Remember that RFCOMM and HID were implemented both in userspace first, before we did the kernel version.

After this is working, we need a subband codec implementation for the ALSA library and then we should really start doing the kernel version of the AVDTP. I don't wanna scare you, but it must look like the RFCOMM one. It needs to do its own L2CAP connection setup.

Marcel

Since you ask for opinions... all but 'Makefile' should be printed out and ritually burned. Just write a proper Makefile. :)

Does btsco work only with headsets or should it also work with mobile phones?

no, btsco doesn't but bluez could. I've added this answer and a link to our page at http://bluetooth-alsa.sourceforge.net/

that should do what you are looking for...
