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. 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?:

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:
