That anti-tearing Xv features only work if Xv renders directly to the front buffer (i.e., no compositor). If you are using a compositor, you need to run a 3D compositor and enable vsync support if you want tear-free video. For non-3D compositors, you can enable the EXAVSync option in the device section of your xorg.conf (Option "EXAVSync" "True"), but it will impact performance. Thanks, this resolves video tearing under newer distros, but I can't understand why videos tear with newer radeon drivers, because under Ubuntu 10.04 (which has xserver-xorg-video-radeon 6.13.0) I don't have to enable EXAVSync to have tear-free video playback. Your older distro may not have composite enabled. The Xv anti-tearing stuff only works without composite. |
