Subject: Re: [h323plus] openmcu hangs when second client accepts invitation

Hello all,

can someone enlighten me on which combination of versions work for
videoconferencing?

I would like very much to help to debug the hang problem with the current
development version, but I would also like to implement a working version if
possible.

Any advice is appreciated.

	With kind regards, Sander

# 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?
