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) 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 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
       drawable.

RETURN VALUES
       [Success]
               Returned if XvPutVideo(3) completed successfully.

       [XvBadExtension]

       [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]
