SDL can use XV for hardware accel. But it is complicated (you have to make sure you use a supported colorformat, otherwise it falls back to software.) But I would be glad if Ekiga/pwlib had one dependency less (it is a little bit strange, pwlib is a portability library, and SDL as well, and only the video part of SDL is used, and even using SDL you have to do a lot of platform specific stuff.) > Just the first issue (see > http://www.libsdl.org/faq.php?action=listentries&category=3#31 > ) rules out SDL under linux.

Nope xdpyinfo: X.Org version: 6.8.2 xvinfo: X-Video Extension version 2.2 screen #0 Adaptor #0: "ATI Radeon Video Overlay" number of ports: 1 This is an Mobility 9000 aka rv250, using the "radeon" (opensource) driver. Might be different with a newer xorg version.
