[h323plus] Problem in receiving 4CIF with H.263 codec

[Simon Horne]

Frame sizes above CIF are handled by a dynamic codec definition in the
plugin. I suggest you download the latest plugins from the h323plus website.

To ensure that 4CIF is available there is a new command in h323plus
H323EndPoint::SetVideoFrameSize().

eg...
AddAllCapabilities(0, P_MAX_INDEX, "*");
SetVideoFrameSize(H323Capability::CIF4MPI);

This will set the maximum allowable framesize for all call to 4CIF.

Hi,
What I've done is, I've added all capabilities first and then set the
topmost priority for "H.263"  (which I assume is dynamic and works for all
sizes including 4CIF).
In H323EndPoint derived class,
AddAllCapabilities(0, P_MAX_INDEX, "*");
PStringArray preferenceorder;
PString str3_4cif = "H.263";
preferenceorder.AppendString(str3_4cif);
capabilities.Reorder(preferenceorder);

This transmits the video to remote site successfully but is not able to show
the received video.
If CIF is selected at remote site, video is displayed on both sides
successfully.
But if 4CIF is selected, video is not shown on any side.
Please Help.
Thanks in advance.
