int vx, vy, dx, dy;
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
specified by your DISPLAY environment variable. The
display option has the format hostname: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 components are: sub‐
window-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 destination (draw‐
able) 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 posi‐
tion 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 closest size supported) and
clipped to the bounds of the drawable.
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 XvVideoNotify 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 signal is interrupted while video is active a
VideoNotify event with detail XvHardError is generated for the draw‐
able.
