Re: Re: feature request: alternative ring audio device

Hello,

Did you made progresses on this patch ?
If not, do you want me to do it ?
Just to be sure that we'll not both do the same thing...

Re: any codecs on ARM SA110 -feedback

Hello,

This problem is usually caused by "not really good" oss sound drivers, 
especially in full duplex mode. I hope alsa drivers to solve that (as they 
did for PCs) but there are not finished for all PDA's sound chipsets of the 
world.

Re: Re: feature request: alternative ring audio device

Hello, and sorry for this late answer:
The usual way to build from cvs is to run
./autogen.sh on the top level directory, then ./configure && make as usual.
The ECONNREFUSED error is strange: nothing changed recently there.
Normally it's defined when including <errno.h>

No I didn't. I've been waiting for your reply on the cvs
issues I've been having. Yes, I ran the autogen.sh thing,
but it still gave me trouble with speex/mediastreamer
(which I solved by setting CPPFLAGS manually) and exosip
(which I never could solve). I haven't tried since I sent
the original email, so I'll be sure to check out a fresh
version and get to it. If I can build it, then I'll be
happy to finish the patch myself.

Give me a few days though. I'm in the middle of a job
transition, and this week is my last week at WingNET,
so I'm a bit pressed for time. It might have to wait
till this weekend.

Re: any codecs on ARM SA110 -feedback

The sound control code for oss is in mediastreamer/osscard.c. I think your oss 
driver doesn't like the way linphone uses it: minimum latency using the 
SUBDIVDE ioctl() and non-blocking read() (uses select with 0 timeout before).
You can try some changes in osscard.c to try to figure out what is going 
wrong.
Good luck,
Simon

Can you give me details (error messages) for this speex issue ?
What is your linux distrib ? This exosip error message seems strange to me. 
The ECONNREFUSED macro is defined in /usr/include/asm-generic/errno.h on my 
linux box, this file being included by <errno.h>.
Can you check that your linphone's cvs build is not conflicting with other 
linphone's libs or header installed in /usr or /usr/local ?

I use speex>=1.1.6, installed in /usr

Re: any codecs on ARM SA110 -feedback

Hi Simon,

	Im glad to get your comments on this.
I have suspected scheduling issue at the read/write operation. To find out
, i just wrote a voice send/receive socket program for simputer PDA.
I have a small jitter buffer of 5x160 bytes. This program worked well, i
could speak and hear proerly on the PDA. There was no voice clutter or
delay in playback.

Simputer has on board Philipls sound chipset.

Could you please suggest me any alternatives on solving this problem.

Thanking you in advance,
Anand

ILBC support

Hello,

Some time ago, draft ilbc support files were posted here.

Simon: did you try compiling them in? I'm completely a dummy on autotools; so 
I'd try them as soon as you get them compiled it.

Pleeease... ILBC is a requirement for my VoIP provider now.
