Hi, > Regarding OPENH323, what is the video interface used ? V4L ? Yes. OpenH323 uses the V4L interface on Linux and has been used with the bttv driver (for TV cards and grabbers using the Bt848/Bt878) and with several USB cameras including ov511s and the Philips. > I want to capture video and multicast it.

Most TV cards use the BT878 and some simple boards with just video inputs use the BT878 > Do I have to use a more expensive TV board for just capturing video > from a camera ? If a BT878 TV Card has a composite video input, you can connect a PAL or NTSC camera and you it with bttv. Roger
