Hi i'm Krit
I'm doing senior project about softphone.
Main functions are video,audio calling, video, audio conferencing and IM.
The server for sip I used Asterisk, XMPP is openfire (IM).
Library I used PJSUA to make audio call but video calling and conferecing.
Please recommend the library that use for video calling and conferencing. Farsight2 can use for windows XP? http://farsight.freedesktop.org
http://videocapture.sourceforge.net/ this library can capture only picture not video recording?
