int XvPutStill(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);
writes a single frame of video to 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.
- Specifies the connection to the X server.

If the port is grabbed by another
client, this request is ignored, and an XvVideoNotify event with detail
