25 port Defines the port from which to get video.

30 gc Defines the graphical context. GC components are: sub‐
31 window-mode, clip-x-origin, clip-y-origin, and clip-
32 mask.
33
34 vx,vy,vw,vh Define the size and location of the source (video)
35 region to be written. vx and vy define the upper-left
36 pixel of the region. vw and vh define the width and
37 height, in pixels, of the region.
38
39 dx,dy,dw,dh Define the location and size of the destination (draw‐
40 able) region into which the video image is written. dx
41 and dy define the upper-left pixel of the region. dw
42 and dh define the width and height, in pixels, of the

46 XvPutVideo writes video into a drawable. The position and size of the
47 source (video) rectangle is specified by vx, vy, vw, and vh. The posi‐
48 tion and size of the destination (drawable) rectangle is specified by
49 dx, dy, dw, and dh.
50
51 Video data is clipped to the bounds of the video encoding, scaled to
52 the requested drawable region size (or the closest size supported) and
53 clipped to the bounds of the drawable.
54
55 If video is successfully initiated, an XvVideoNotify event with detail
56 XvStarted is generated for the drawable. If the port is already in
57 use, its video is preempted, and if the new drawable is different than
58 the old, an XvVideoNotify event with detail XvPreempted is generated
59 for the old drawable. If the port is grabbed by another client, this
60 request is ignored, and an XvVideoNotify event with detail XvBusy is
61 generated for the drawable. If the port is not receiving a valid video
62 signal or if the video signal is interrupted while video is active a
63 VideoNotify event with detail XvHardError is generated for the draw‐
64 able.
