Description John T. Shaw 2004-03-09 15:55:36 UTC
I first notice I wasn't getting Xv support when I tried running mplayer and get
this message:

Xlib:  extension "XFree86-VidModeExtension" missing on display ":0.0".
vo: X11 running at 1280x1024 with depth 24 and 32 bpp (":0" => local display)
It seems there is no Xvideo support for your video card available.

I thought perhaps it was because mplayer doesn't recognize XServers XVideo
extension because it looks specifically for the "XFree86-VidModeExtension".

I ran xvinfo and I got the following message:
X-Video Extension version 2.2
screen #0
 no adaptors present

I also tried it with xine and go this message:
This is xine (X11 gui) - a free video player v0.9.23.
(c) 2000-2003 The xine Team.
main: video driver <xv> failed

According to xdpyinfo I do have the XVideo extension:

Is the XVideo extension simply not finished? or am I doing something wrong here?

weird as it sounds, it's perfectly legal to advertise the XVideo extension but
not any Xv adaptors.  what hardware is this with?

no response from reporter, closing.
