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:

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

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/avidemux2_gtk matches
Binary file /usr/bin/audacity matches
Binary file /usr/bin/avidemux2_qt4 matches
Binary file /usr/bin/avidemux2_cli matches
Binary file /usr/lib64/libADM5avcodec.so.53 matches
Binary file /usr/lib64/opal-3.10.10/codecs/video/mpeg4_ffmpeg_ptplugin.so matches Binary file /usr/lib64/opal-3.10.10/codecs/video/h264_x264_ptplugin.so matches Binary file /usr/lib64/opal-3.10.10/codecs/video/h263_ffmpeg_ptplugin.so matches 
Binary file /usr/lib64/xine/plugins/1.30/xineplug_decode_ff.so matches
Binary file /usr/lib64/libavcodec.a matches
Binary file /usr/lib64/ADM_plugins/videoEncoder/libADM_vidEnc_avcodec.so 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:

ekiga -d 4 2>&1 | grep Error

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.
