Audio/Video conversation

[kakaroto]

Hi Kalinda,
the voice chat is ready, but I haven't released libnice yet, so I'm waiting until we release the 0.0.2 version of libnice and 0.0.4 version of farsight2 (which will support libnice). It should be done sometime next week.
Once it's all done, then you can probably request ubuntu to make a package out of those... if they are too slow, I can make one...
But note that ubuntu hardy has old dependencies, so even if they create libnice and farsight2 packages, there dependencies will be too old to work, so you will need to change your apt source to Intrepid instead of Hardy... or just use the Intrepid packages as they should work on Hardy...
either way, packaging is not my concern :p

[trv]

or just upgrade to Intrepid, it's pretty stable even now. Or just way 2 weeks until it's released. Once you're on intrepid, then you will need just the libnice and farsight2 debs (made from the packages kakaroto will release next week)

Hi Kakaroto,
(been busy for a while sorry for answering 2 pages late !). Thanks you for this, that sounds useful. I will try new svn version and be careful with sound mixing.

 

@farseeing :
ok, i got some news for you :
1 - the freezing seems to happen when someone sends you an invite and cancels it right away, so I'm guessing that while you were having that audio call, someone sent you an invite and canceled it (or something similar happened) and that made amsn freeze... that issue is now fixed in the latest SVN version of amsn.
2 - The problem where amsn says you don't have farsight because it reports :

Quote:
** (<unknown>:8314): DEBUG: Got an error on the BUS (4): Could not open audio device for recording. Device is being used by another application. (gstalsasrc.c(635): gst_alsasrc_open (): /pipeline/gconfaudiosrc1/bin5/alsasrc1:
Device 'hw:1,0' is busy)

this happens when amsn tries to launch farsight at the same time as it's playing a sound, so if for example, you start a call, cancel it right away, then try to start it again (before the 'ringing' sound has finished playing), then it will have this error..
If you try to launch amsn at the same time as someone connects/changes state or whatever that causes amsn to play a sound, then it will fail... so that's the trick! Hopefully, we'll have sometime in the future a better system for all of this, don't worry.

p.s.: I still get the memory corruption, but it seems much harder to reproduce...

Alrighty, sounds good Thanks

Yeeeah... I could... buuuut... I use Kubuntu... and KDE 4 is not ready for me yet... perhaps in January when they release 4.2. I'm glad the release I'm stuck with is LTS, though. That doesn't matter too much anyhow, as Intrepid packages will work in Hardy.

I did everything in your post but amsn svn cant find farsight2 to compile sadly   I`m on F9 x86_64    Any clue ?       (I did ldconfig thing as writed)

Got it work on Fedora 9 !
Spent hours with snack2.2 and finally gave up and tried farsight. So for those who may be helped by that, here are some tips I had to do to adapt the procedure on the beginning of this thread to my needs.

I'm using :
- fedora 9 with kernel 1.6.25 (due to graphic driver issues, hum, well...anyway)
-pulse-audio, alsa and all this stuff I don't understand anything in !
-aMSN from svn : v.10479 at this very second
- farsight 2 : 0.0.3 (had to cheat see below) --> http://farsight.freedesktop.org/releases/farsight2/farsight2-0.0.3.tar.gz
- gst-plugins : 0.12.9  --> use yum or add/remove software, all plugins available for F9 in my configured repositories (usuals + livna)
- libnice.


I've just followed the above procedure (obviously using yum instead of apt)  except for several points where I had to struggle with versions problems :

# I followed the procedure using git but the version of farsight2 there didn't seem to work.
so I downloaded farsight2-0.0.3.tar.gz (see link above), unpacked and manually copy files in farsight2-0.0.3/common from the git tree of farsight2 I created : gst-autogen.sh, gst.supp. -I have 4 files & 1 folder in this directory). I'm then using this version of farsight2 instead of the git tree version

# After the ./configure step in farsight2-0.0.3 installation and just before the make, I edited farsight2.pc and farsight2-0.10.pc and change version 0.0.3 by 0.0.3.1. then go back to the procedure and perform make and make install. (otherwise aMSN doesn't recognized farsight.).

#  (yes, don't forget to do the ldconfig as prescribed !)

# then I installed aMSN

AND THAT'S WORKIN DAMN FINE RIGHT NOW !!!!

Hell yes!
Same here

So to sum things up:

Install the following packages from the repo's:

Code:

gstreamer-plugins-bad-0.10.7-1.lvn9.i386
gstreamer-0.10.19-1.fc9.i386
gstreamer-plugins-good-0.10.8-8.fc9.i386
gstreamer-tools-0.10.19-1.fc9.i386
gstreamer-plugins-pulse-0.9.5-0.5.svn20070924.fc9.i386
gstreamer-plugins-base-devel-0.10.19-2.fc9.i386
gstreamer-plugins-bad-extras-0.10.7-1.lvn9.i386
gstreamer-plugins-base-0.10.19-2.fc9.i386
gstreamer-plugins-bad-devel-0.10.7-1.lvn9.i386
gstreamer-devel-0.10.19-1.fc9.i386
gstreamer-plugins-good-devel-0.10.8-8.fc9.i386
gstreamer-plugins-ugly-0.10.8-1.lvn9.i386

Install the latest gst-plugins-farsight (the one from the repo's is outdated).

Code:

wget http://farsight.freedesktop.org/releases/gst-plugins-farsight/gst-plugins-farsight-0.12.9.tar.gz
tar zxfv gst-plugins-farsight-0.12.9.tar.gz
cd gst-plugins-farsight-0.12.9
./configure --prefix=/usr
make
sudo make install
cd ..

Obtain and install libnice (be sure to have git installed: sudo yum install git)

Code:

git clone git://git.collabora.co.uk/git/user/kakaroto/nice.git libnice
cd libnice
git checkout -b nice-kakaroto origin/nice-kakaroto
./autogen.sh --prefix=/usr
make
sudo make install
cd ..

Install farsight2

Code:

git clone git://git.collabora.co.uk/git/user/kakaroto/farsight2.git farsight2
cd farsight2
git checkout -b nice origin/nice
cd ..
wget http://farsight.freedesktop.org/releases/farsight2/farsight2-0.0.3.tar.gz
tar zxfv farsight2-0.0.3.tar.gz
cd farsight2-0.0.3
cp -f ../farsight2/common/check.mak ./common/
cp -f ../farsight2/common/gst.supp ./common/
cp -f ../farsight2/common/gst-autogen.sh ./common/
cp -f ../farsight2/common/gtk-doc.mak ./common/
./autogen --prefix=/usr --disable-python
nano -w farsight2.pc

Now change the version from 0.0.3 to 0.0.3.1
Press CTRL+O to save and CTRL+X to quit nano.

Code:

make
sudo make install
sudo /sbin/ldconfig
cd ..

Voila, check out the latest svn of amsn and you should be able to make voice calls:)

[kakaroto]

make sure you used the GIT repository of farsight2, that you did the checkout of the appropriate branch, and that you configured it with --prefix=/usr...
Many people seem to screw it up, but then when they retry everything and make sure they follow my step by step guide, it works fine for them in the end...

[lordamus]

yeah First I tryed farsight2.0.0.3 then your GIT repository but farsight2 cant find libnice to compile error..LIbnice compiled well from your repository(I use ./autogen.sh --prefix=/usr )

hummm... libnice seems to install correctly.
Can you please see if there's a file  /usr/lib/pkgconfig/nice.pc on your system.
and type

Code:

pkg-config nice --modversion

and paste here the output...
this should tell us if pkg-config can find libnice or not.
thanks!

[lordamus]

farsight2]# pkg-config nice --modversion
Package nice was not found in the pkg-config search path.
Perhaps you should add the directory containing `nice.pc'
to the PKG_CONFIG_PATH environment variable
No package 'nice' found

yea there is a file nice.pc  in  /usr/lib/pkgconfig/    

prefix=/usr
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
includedir=${prefix}/include

Name: libnice

Maybe some shared lib problem on my x86_64 fedora  ?

hummm... libnice seems to install correctly.
Can you please see if there's a file  /usr/lib/pkgconfig/nice.pc on your system.

[kakaroto]

humm... :

Code:

echo $PKG_CONFIG_PATH

? in theory /usr/lib/pkgconfig should be the default.. maybe something is different on your system.

that command shows nothing... I`ve  /usr/lib/pkgconfig  and /usr/lib64/pkgconfig   /usr/share/pkgconfig...   also  /usr/local/lib/pkgconfig/nice.pc     Any clue ?

humm... :

Code:

echo $PKG_CONFIG_PATH

? in theory /usr/lib/pkgconfig should be the default.. maybe something is different on your system.

nope!, no clue at all! try pasting here the output of

Code:

pkg-config --debug --print-errors nice --modversion

with this --debug option, it should give you the list of all files it scans! if there's anything wrong, then you'll find it with it.. maybe try to see if it searches for .pc files in /usr/lib/pkgconfig or if it looks in another directory...
either way, in theory if you do "export PKG_CONFIG_PATH=/usr/lib/pkgconfig" (since you said the file /usr/lib/pkgconfig/nice.pc exists there) then it should work....
make sure btw that the file is readable!

here is the output   http://pastebin.com/d2302dd38      package nice not found...it looks directly to /usr/lib64/pkgconfig   so I`m on 64bit system... Maybe if I change pkg_config_path to /usr/lib/pkgconfig  there will be problems

Edit:  I did  export PKG_CONFIG_PATH=/usr/lib64/pkgconfig:/usr/lib/pkgconfig/  and then farsight2 compiled well with no errors and I did ldconfig then compiled amsn svn 10606 without errors it found farsight well..But when I open amsn audio/video config it cant find farsight module ?  I did package require Farsight in amsn console it returns "0.1" and then farsight Prepare 1 it returns "Couldn't create fsrtpconference"   what can I do ?   I`m using gst-plugins-farsight-0.12.9  (compiled)

nope!, no clue at all! try pasting here the output of

Code:

pkg-config --debug --print-errors nice --modversion

with this --debug option, it should give you the list of all files it scans! if there's anything wrong, then you'll find it with it.. maybe try to see if it searches for .pc files in /usr/lib/pkgconfig or if it looks in another directory...

you're missing gstreamer-plugins-bad.
Again.. like I said, make sure you follow the wiki and don't forget any dependency!!!!

EDIT: it looks like it actually can't find the farsight2 plugin.. make sure you installed farsight2 with --prefix=/usr... again, read the guide correctly and do everything as it tells you to...
