XvPutVideo(dpy, port, d, gc, vx, vy, vw, vh, dx, dy, dw, dh)
int vx, vy, dx, dy;
unsigned int vw, vh;
unsigned int dw, dh;
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.
Defines the port from which to get video.
Defines the drawable (window) into which video is to be written.
Defines the graphical context. GC components are: subwindow-mode, clip-x-origin, clip-y-origin, and clip-mask.
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.
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.
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.
