The problem is the generic information on profile and level are not being
read from the plugin and exchanged. The same problem exists with MPEG4
plugins. 

Currently working on a fix.

Hello Chin

   H264 (and other resolutions above 4CIF and like vga, wvga etc) is not
part of H323 stack. One way to use it is with the extended video capability,
them both end-points can agree on a specific and possible proprietary
CODECs.
