Yes I can remove but I dont want to..
I am adding H323_h224 capability for Far End Camera Control. Is this the
reason for Multiple control channel

Sorry for the delay
You can disable extended video capability by
RemoveCapability(H323Capability::e_ExtendVideo);
But I don't think that is the problem. As I mentioned before you are
opening
2 control channels somehow.

Simon, Robert
I am not using H323Connection::OnSendCapabilitySet()
Robert, As you suggested I go through my code many times and have taken
great care of pointers.
I tried to debug the library and I find the reason for PTlib crash. I am
not
sure.but It solved the problem for me
In file h323caps.cxx
Line no . 2064
BOOL
H323CodecExtendedVideoCapability::OnSendingPDU(H245_VideoCapability &
pdu) const
{
.
.
.
.
1 if (table.GetSize() > 0) {
2 caps.SetSize(table.GetSize());
3 for (PINDEX i=0; i< table.GetSize(); i++) {
4 H245_VideoCapability vidcap;
5 ((H323VideoCapability &)table[i]).OnSendingPDU(vidcap);
6 caps[i] = vidcap;
7 }
8 } else {
9 caps.SetSize(extCapabilities.GetSize());
10 for (PINDEX i=0; i< extCapabilities.GetSize(); i++) {
11 H245_VideoCapability vidcap;
12 ((H323VideoCapability
&)extCapabilities[i]).OnSendingPDU(vidcap);
13 caps[i] = vidcap;
14 }
15 }
Here in line no. 1 if (table.GetSize() > 0) { table.GetSize() does not
get
initialsed after the end of the call
table.GetSize() increases in order 0, 2, 4, 16, 32, 64, 128, 256 and
crash........
I am not using Extended channel. But by default plugins add H.263
extended
capabilities.
How to avoid this?? Where is the problem??
