Hello,
I just read the thread this morning :
- No trouble using Linphone or Ekiga with any version of
Asterisk. I use it. Conf seems OK but check your user is well
registered and have the right properties.
- ffmpeg or libav: I had this problem. See
ekiga-devel mailing list archive

There is also a big problem with
libav (for linux). Debian provides a standard
stripped libav . To have symbols, it is necessary to
install debug packages.
There is also troubles with deprecated functions and then
the dyna mecnism
doesn't work. This implies that it is impossible to use
opal codecs.
I use the last version of libx264 and ffmpeg with an
unstable version of Slackware. I have too much trouble with
libav and opal/ptlib when compiling on my slackware
platform. It is necessay to patch a little bit opal
(changing some Codec_ID by AVCOdec_id .... adding some
missing CODEC_FLAG_H263P..). avcodec_init error is not
important because this call was useless. I checked your log
and found nothing. Check your environnement : it is
mandatory to have only one version of ffmpeg or libav. If
you compile ffmpeg, use ./configure <your flags>
--enable-libx264 --disable-stripping for dyna (dlopen
dlsym..)

What Asterisk are you running?
Is it a default distro like FreePBX? There
are some configs to check, but they are mush easier
using the freePBX GUI.
But apart from my asterisk server I only get video on
ekiga.net's echo
tester with h261 too.
If it helps any, these are the output of -d 4. The first
is using h261
and the second is h263. I rang the ekiga.net echo line
then hungup
afterwards:
h261: http://www.r0t.co.uk/paste/p/qJ9yve44.html

You should report a bug to your distribution maintainer.

My guess would be that it links to a different libavcodec
library than the
one whose headers were used to compile things.
I've just recompiled both Opal and Ekiga and get the same
error.
There's no way that it's compiled against a different
version. Is
there a recommended ffmpeg version to use?
Currently, I have version 2.1.4.
Have you seen this?:
http://lists.mplayerhq.hu/pipermail/ffmpeg-devel/2012-April/123454.html
I will have to patch Opal by the look of it.
If the compilation succeeded, that means that avcodec_init was
present in your
headers.
If it fails at runtime, that means that the library you are
linking to does not
contain that method.
=> your headers and libraries are different, believe me
Perhaps you have ffmpeg/libav installed from your distribution,
and you also installed it manually? During compilation, one of
them is used, and during execution the other gets used.
Slackware doesn't have ffmpeg in it's stock repo. But like I said
I
rebuilt both Opal and Ekiga from what I had installed, and there
is
only one version installed.
Also, do you use ffmpeg or libav?
ffmpeg. I did try libav just now but Opal wouldn't build against
it.
I notice that plugins/video/common/dyna.cxx for example uses
avcodec_open() when since ffmpeg-1.x avcodec_open2() is used.
There
are similar problems with avcodec_alloc_context /
avcodec_alloc_context3. This looks like a big upstream mess to me.
I am going to downgrade to ffmpeg 0.11.5 if I can fix the doc
bugs.
