Hello Simon,

Are you using ptlib 2.8.0 ? The error is in the PSoundChannel_WAVFile class in ptlib. ptclib/pwavfiledev.cxx Replacing both the .h and .cxx file or reverting back to ptlib 2.6.0 will fix the problem.
There was a change made in the last ptlib release which I am currently debugging.
I'm affraid that didn't work out (openmcu still hangs when the second ekiga clients accepts the invitation).
First I tried to copy the two files over from ptlib 2.6.5 to the svn version of ptlib. This didn't compile (can provide errors if useful).
Then I tried to compile ptilib 2.6.5 and the other software from cvs/svn. Ptlib compiled, but h323plus did not.
h323plus-v1_21_0.tar.gz did compile, and so did the rest, but to no avail.
Are you sure the error is in pwavfiledev.* ? If you are not, how can I best debug?
With kind regards, Sander

Dear all,
I'm trying to do a three-way videoconferencing with openmcu.
After inviting two ekiga clients to the same conference room (from within the webinterface), openmcu hangs.
Hangs means: http://10.0.0.1:1420/Status doesn't refresh anymore (reload times out eventually) and openmcu has to be killed with -9.
When inviting the first ekiga client, the client sees the openmcu logo as 'remote video', and that client gets listed on the status page.
When inviting the second ekiga client to the same room, that client sees it's own video, and 'remote video' is grayed out.
If the second client is invited to a different room from the first instead, both clients see the openmcu logo (and openmcu doens't hang and the status page gets refreshed with both clients listed in their rooms).
This all happened back in early february too. Now I found the time to try again.
I've read al mails in the archive at http://lists.packetizer.com/pipermail/h323plus/ from november 2009 till now, but didn't find a similar case.
The system on which all software is compiled and which is running openmcu, is an up to date Debian Sid (unstable) amd64, and selfcompiled kernel 2.6.32-rc6.
The clients are a Debian Sid on Intel Core2 Duo and a Debian Sid on ARM (SheevaPlug).
How can I debug what happens to openmcu? Or is there an obvious mistake in the steps below?
With kind regards, Sander
