  .SH ARGUMENTS
  .\"
  .IP \fIdpy\fR 15
  Specifies the connection to the X server.
  .IP \fIport\fR 15
  Defines the port from which to get video.
  .IP \fId\fR 15
  Defines the drawable (window) into which video is to be written.
  .IP \fIgc\fR 15
  Defines the graphical context.

  .IR clip-y-origin ,
  and
  .IR clip-mask .
  .IP \fIvx,vy,vw,vh\fR 15
  Define the size and location of the source (video) region
  to be written.  \fIvx\fP and \fIvy\fP define the
  upper-left pixel of the region. \fIvw\fP and \fIvh\fP
  define the width and height, in pixels, of the region.

  .SH DESCRIPTION
  .\"
  XvPutVideo writes video into a drawable.
  The position and size of the source (video) rectangle is specified by
  .IR vx ,
  .IR vy ,
  .IR vw ,
  and
  .IR vh .
  The position and size of the destination (drawable)
  rectangle is specified by
  .IR dx ,
  .IR dy ,
  .IR dw ,
  and
  .IR dh .
  .PP
  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.
  .PP
  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 drawable.
