So have you got video preview in linphone app? Could you explain in details how you done it?
Could you explain how have you done it via RFC? I do not know what you mean.
Yea, I know it is not easy task but I have done some changes for now, like I've add Dialog establishment signaling after...
@AndFed have you any success with the video preview in the Linhome app?
I have attached the wireshark pcap with vto call to vth. Pcap shows the SIP signalization that would help resolve your issue. I am also trying to make works video preview in this app with no success for now.
