unsigned int vw, vh;
unsigned int dw, dh;
Arguments
dpy Specifies the display screen on which the
Xv Server is to accept requests from Xv
clients. If the display option is not
specified, Xv uses the display screen spec-
ified by your DISPLAY environment variable.
The display option has the format host-
name:number. Using two colons (::) instead
of one (:) indicates that DECnet is to be
used for transport.
port Defines the port from which to get video.
d Defines the drawable (window) into which
video is to be written.
gc Defines the graphical context. GC compo-
nents are: subwindow-mode, clip-x-origin,
clip-y-origin, and clip-mask.
vx,vy,vw,vh Define the size and location of the source
(video) region to be written. vx and vy
define the upper-left pixel of the region.
vw and vh define the width and height, in
pixels, of the region.
dx,dy,dw,dh Define the location and size of the desti-
nation (drawable) region into which the
video image is written. dx and dy define
the upper-left pixel of the region. dw and
dh define the width and height, in pixels,
of the region.
DescriptionXvPutVideo writes video into a drawable. The position and
size of the source (video) rectangle is specified by vx,

vy, vw, and vh. The position and size of the destination
(drawable) rectangle is specified by dx, dy, dw, and dh.
Video data is clipped to the bounds of the video encoding,
scaled to the requested drawable region size (or the clos-
est size supported) and clipped to the bounds of the draw-
able.
If video is successfully initiated, an XvVideoNotify event
with detail XvStarted is generated for the drawable. If
the port is already in use, its video is preempted, and if
the new drawable is different than the old, an XvVideoNo-
tify event with detail XvPreempted is generated for the
old drawable. If the port is grabbed by another client,
this request is ignored, and an XvVideoNotify event with
detail XvBusy is generated for the drawable. If the port
is not receiving a valid video signal or if the video sig-
nal is interrupted while video is active a VideoNotify
event with detail XvHardError is generated for the draw-
able.
