VSync (mplayer) & Composite

hey!
i have got an old problem since gentoo. i am using archlinux now but the problem still exists: it seems to be that vsync is not activated when i run xcompmgr. i have that horizontal flickering when playing movies. there is no problem when running mplayer without xcompmgr. here is my xorg.conf:

Section "ServerLayout"
    Identifier     "Layout0"
    Screen      0  "Screen0"

Re: VSync (mplayer) & Composite

I have the exact same problem. The only diference is that i have been having that bug since Ubuntu, Now i am on arch using xmonad, but still the problem persists even with diferent video cards. Every time xcompmgr is on i get horizontal flickering when playing movies, and there is no problem otherwise.

Here it is my xorg.conf :

Re: VSync (mplayer) & Composite

sorry mate... X doesn't support vsync yet... You can still try to use gl2 as mplayer -vo and manually set the refresh rate of your monitor to seamlessly solve the problem when playing videos, but you are never going to get a "real" vsync :-(

Re: VSync (mplayer) & Composite

I've been having this problem too with nvidia, explicitly disabling composite in xorg.conf along with setting the correct xv sync device via nvidia-settings works for me, or simply using VDPAU (if your card supports it).

Re: VSync (mplayer) & Composite

xcompmgr causes tearing, but i've got rid of them with other composite managers, like compiz or kwin.
If your card supports it (xvinfo to check), then set mplayer to use the overlay adaptor, that should 99% fix any tearing issue.
