What Asterisk are you running? Is it a default distro

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

You should report a bug to your distribution maintainer.
Things are badly

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.


Impossible !
What does :
grep avcodec_init /usr/ -r
return ?


Ok

grep -r avcodec_init /usr

Binary file /usr/bin/audacity matches

So the static /usr/lib64/libavcodec.a has the old _init()
function, but:


ugh that was from libav. Thought I'd removed it.


Ok so after removing libav and rebuilding yet again:

That means that when compiling OPAL the avcodec_init method was
present in the ffmpeg headers, and when running the executable, it is
not present anymore.

I see Opal picks the plugins in /usr/lib64/opal-3.10.10/codecs/video/

Isn't that the place of an older Opal plugin that was compiled once
with an older ffmpeg ?

Anyway, I can not really help more than this. When you link to a
library at runtime and it compiains that it does not find a symbol,
it means that the compilation was done with headers from a different
(and incompatible) version of the library.


All I did, and this is what I did originally, is build/install ffmpeg
2.1 and then Opal/ekiga.

I don't know where plugins should go, but here is a list of all:

http://www.r0t.co.uk/paste/p/pdoGLS92.html

Trust me, there is no other opal or ffmpeg on my system.
Both the ffmpeg and opal slackbuilds are on slackbuilds.org. If they
are wrong please let me know.

By the way, I'm the slackbuild maintainer for ptlib, opal and ekiga
and I do want to sort this out as ekiga is the only sip/voip app that
looks like any thought went into its gui.

I use ffmpeg from git (version # N-61767-gc08e523) with libx264 from git
./configure --enable-shared --enable-libx264 --enable-gpl
--disable-stripping && make && make install
Don't forget disable stripping. I also work with some limitation with
libav. (dyna, slopen, dlsym).
Dyna.cxx from opal dlopens libavcodec.so and check functions using
dlsym.
If libavcodec is stripped, dlsym fails (and of course dyna).
For avcodec_init, last versions of opal didn't use this call anymore and
in opal_10 this call is deprecated -  see
opal/plugins/video/common/ffmpeg/libavcodec/avcodec.h


Thanks Thierry. This had me looking in the right direction. It turns
out to be --enable-shared in ffmpeg that is the problem. I still don't
get video for h.263 but that avcodec_init error is gone.

Here's what I see now:

2014/03/25 07:44:09.828   0:07.099          Pool:0x7f1008084700 Opal

I'll keep plugging away at this.

Check if configure generates Makefile and make builds all plugins.
I had to add  -fpermissive flag in Makefile.in, some CODEC_FLAG_Hxx in
h263xx.cxx, and change CodecID by AVCodecID


Yeah, I have a patch for that AVCodecID problem.

Here's a full message though. It seems to be looking in the wrong place
for them:

Looks like I need to build this in a chroot, since my system is multilib.
That may be messing with it.
