Dear Sir,
    Some problems I would like please you for help on h323.
    On H.239, we modify the code from simple project, when we open the usb camera (Via OpenVideoChannel in main.cxx of simple), the image can appear normal. But the H.239 open, they can not show usb camera and H.239 at the same time , that is, to receive the H.239 error OpenLogicalChannel. I copy the method from OpenVideoChannel to implement H.239. But no work. Could you please help me to solve this.

I found that I can send H.239 packets, but receive not work.
Does it will open two windows of both usb camera and h.239 data sharing window ? I try to use usb camera and fake video. But both of them show on the same window and preempt the same window resource resulting segmentation  fault.
Could you give any advice for me ?


Thanks & Regards,
Hans
