I've been playing around with some video stuff and became curious about
the XvPutVideo function. The function has a man page, and my video card
supports the function directly as shown by the output of xvinfo. From
the man page:
XvPutVideo(3x)
Name
XvPutVideo - write video into a drawable
Syntax
#include <X11/extensions/Xvlib.h>
XvPutVideo(dpy, port, d, gc, vx, vy, vw, vh, dx, dy, dw, dh)
Display *dpy;
XvPortID port;
Drawable d;
GC gc;
int vx, vy, dx, dy;
unsigned int vw, vh;
unsigned int dw, dh;
So my question is: How do I find where Display, XvPortID, Drawable, and
GC are declared? I have tried to grep through the header files and it is
an overwhelming problem. Is there some search technique I can use? Or
perhaps build some tiny app and use a debugger to tell me where the
stuff comes from?
