Digging into the trace deeper, the actual last line before it crashes is:
0:19.341 H225 Answer:41fde940 PWLib Assertion fail: Invalid cast to non-descendant class, file h245_3.cxx, line 2805, Error=22
This is a componet of H323Plus and not PTlib.
Any ideas what would cause this?
Thanks

Hi Simon,
I did this, and now it looks like everything loads and negioates: 1: H.261-CIF{sw} <24> H.261-QCIF{sw} <25> H.261{sw} <26> H.263{sw} <27> MPEG4{sw} <28> 2:
However when I try to connect a H.261 endpoint (vanilla Ekiga installed from Ubuntu repos), openmcu coredumps as follows:
0:08.158 H225 Answer:401c6940 PWLib Assertion fail: Invalid cast to non-descendant class, file ptlib/common/contain.cxx, line 334, class PBYTEArray, Error=107
This is where it asks if I want to (A)bort or (C)ore dump.
Any ideas? This is a freshly compiled PTLIB 2.6.7

Comment out line 323 SetVideoFrameSize() in h323.cxx. The opal plugins should load and be usuable. Also you will need to enable H.323 in H.264.

Simon,
My apologies, I forgot that I tried to use OPAL 3.6.8 plugins, which is what I had PTLIBPLUGINDIR set to for that test.
Does that make a difference if I were to use H323Plus plugins vs OPAL ?
When I use the H323Plus plugindir, it doesnt seem to find H.263 at all, using OPAL loads H.263/264/MPEG4 but they never end up staying loaded.
Thanks,
Dave

What H.263 plugin are you using? I don't see H.263-CIF and H.263-QCIF definitions loading?
The H.263{sw} codec is being filtered out. Remove the SetVideoFrameSize(H323Capability::cifMPI) function out of your code and both the MPEG4 and H.263 codecs will load.

Simon,
On my RHEL (actually Oracle Enterprise Linux) machine I initially attempted this on with the same PTLIB/H323PLUS/OPENMCU combo, heres the level 5 output when I start OpenMCU. It looks like it loads everything then removes them, and I am only left with H.261 CIF

Do a level 5 trace and see if the H.263 capability actually loads and in the capability list. The plugin will not load unless it finds the FFMPEG library. If it is there then you will need to check that it actually gets negotiated, see if it is the common capability list in the trace file.
The H.264 plugin should work if you are using the current CVS. Use a softphone like Mirial to test.

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
