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. Taranpreet
