Just to confirm:

  /* Add video capabilities */
  if (video_size == 1) {

    if (autoStartTransmitVideo && !autoStartReceiveVideo) {

      /* CIF Capability in first position */
      AddCapability (new H323_H261Capability (0, 1, FALSE, FALSE, 6217));
      AddCapability (new H323_H261Capability (1, 0, FALSE, FALSE, 6217));
    }
    else {

      /* CIF Capability in first position */
      SetCapability (0, 1, new H323_H261Capability (0, 1, FALSE, FALSE, 
6217));
      SetCapability (0, 1, new H323_H261Capability (1, 0, FALSE, FALSE, 
6217));
    }
  }
  else {

    if (autoStartTransmitVideo && !autoStartReceiveVideo) {

      AddCapability (new H323_H261Capability (1, 0, FALSE, FALSE, 6217));
      AddCapability (new H323_H261Capability (0, 1, FALSE, FALSE, 6217));
    }
    else {

      SetCapability (0, 1, new H323_H261Capability (1, 0, FALSE, FALSE, 
6217));
      SetCapability (0, 1, new H323_H261Capability (0, 1, FALSE, FALSE, 
6217));
    }
  }
}

Change to:

  /* Add video capabilities */
  if (video_size == 1) {

    if (autoStartTransmitVideo && !autoStartReceiveVideo) {

      /* CIF Capability in first position */
AddCapability(0, 1, new  H323_RFC2190_H263Capability(0, 0, 2, 0, 0, 
maxbps));
AddCapability(0, 1, new  H323_RFC2190_H263Capability(0, 1, 0, 0, 0, 
maxbps));
    }
    else {

      /* CIF Capability in first position */
SetCapability(0, 1, new  H323_RFC2190_H263Capability(0, 1, 0, 0, 0, 
maxbps));
SetCapability(0, 1, new  H323_RFC2190_H263Capability(0, 0, 2, 0, 0, 
maxbps));
    }
  }
  else {

    if (autoStartTransmitVideo && !autoStartReceiveVideo) {

AddCapability(0, 1, new  H323_RFC2190_H263Capability(0, 0, 2, 0, 0, 
maxbps));
AddCapability(0, 1, new  H323_RFC2190_H263Capability(0, 1, 0, 0, 0, 
maxbps));
    }
    else {

SetCapability(0, 1, new  H323_RFC2190_H263Capability(0, 1, 0, 0, 0, 
maxbps));
SetCapability(0, 1, new  H323_RFC2190_H263Capability(0, 0, 2, 0, 0, 
maxbps));
    }
  }
}
