[h323plus] h323plus 1.22, ptlib 2.8.2, openmcu 2.2.5 - can't get H.263 to load

[Alex Katebi]

Hi Dave,

   In my experience if the plugin library has some unresolved symbols then it won't load. 
Also put a gdb break in file osutils.cxx in ptlib where dlopen is used to load the plugin. I think the name of the function is PDynaLoad::Open.
You can see if the loading was successful or not.

Thanks,
Alex

I am having a terrible time trying to get basic H.263/264 plugins working
on a vanilla Ubuntu 10.04 install.

I installed ffmpeg, libavcodec-devel, x264, libx264-devel from ubuntu repos

Compiled PTlib 2.8.2, set PTLIBDIR, compilied h323plus 1.22, set
OPEN323DIR, configured and make installed h323plus/plugins (showed all the
codecs as enabled), set PTLIBPLUGINDIR to the OPENH323DIR/plugins.
Compiled openmcu 2.2.5 without issues...

When I run openmcu, right out of the box H.261 and H.264 are enabled, but
if I try to connect an endpoint (using Ekiga) it segfaults openmcu.  If I
disable h.264 via openmcu.ini, restart openmcu, I can connect an endpoint
at H.261 CIF (which is terrible resolution and pretty much useless to me.
The problem is I cant seem to get H.263 to load at all.

Can someone that has had good results setting this up please shed some
light on how to do it on a more recent OS like Ubuntu 10.04 or even RHEL5?

Thanks
Dave
