NAME
       XvPutVideo - write video into a drawable

SYNOPSIS
       #include <X11/extensions/Xvlib.h>

       int XvPutVideo(Display *dpy, XvPortID port, Drawable d, GC gc,
		      int vx, int vy, unsigned int vw, unsigned int vh,
		      int dx, int dy, unsigned int dw, unsigned int dh);

ARGUMENTS
       dpy	      Specifies the connection to the X server.

       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: 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  destination  (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.

DESCRIPTION
       XvPutVideo writes video into a drawable.  The position and size of the source (video) rec-
       tangle 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 draw-
       able region size (or the closest size supported) and clipped to the bounds  of  the  draw-
       able.

       If video is successfully initiated, an XvVideoNotify event with detail XvStarted is gener-
       ated 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.

RETURN VALUES
       [Success]

       [XvBadAlloc]
	       Returned if there were insufficient resources to process the request.

DIAGNOSTICS
       [XvBadPort]
	       Generated if the requested port does not exist.

       [BadDrawable]
	       Generated if the requested drawable does not exist.

       [BadGC] Generated if the requested graphics context does not exist.

       [BadAlloc]
