If you are able to connect with PVX at 4CIF then it must be working.
I had a look and there is a small bug in OnStartHandleControlChannel() which causing the error in StartHandleControlChannel(). I accidentally introduced this bug in the last commit when I did the H460.18/19 work. You need to patch h323.cxx with the following.
BOOL H323Connection::OnStartHandleControlChannel() + if (controlChannel != NULL) { PTRACE(2, "H245\tHandle control channel"); return StartHandleControlChannel(); + } else + return StartControlNegotiations(); }
I have checked the fix into the CVS and updated the package on the website.
To assist with debugging it's also a good idea to include tracelogs so we can see exactly why 4CIF is not working.

Hi
I have tried to incorporate 4cif image size in MYPhone by setting videowidth = 704 and videoHeight = 576. It is working fine with Polycom PVX. 4CIF video is received on Polycom side.
But when I run MyPhone on both sides with 4cif image transmission set ,no video is being transmitted.The video channel is opened but still video is not seen and MyPhone crashes IN H323Connection::StartHandleControlChannel().
controlChannel is NULL in this function and it crashes.
Can someone help me with 4cif transmission. I doubt that version 1.20 supports 4cif transmission when H323+ library is being used on both the sides. I have tried to transmit 4cif with my sample application on both sides but it is also not working. I have tested 4cif with OpenH323(older ) version 1.15.6 and it was working fine with 4cif.
If someone else has tested this feature on 1.20 release of H323+ ,please help!!
Thanks.
