I'm attacking the bottle necks in my app........ and I've just noticed that XvShmPutImage is one of my bottlenecks. It takes 4 msecs to draw 1 512 x 256 sized frame.
I suspect that I am doing something wrong, but I cant find what. Maybe it is how I initialise the shared memory.
I've attached the code, wondering if anyone can see any glaring mistakes that could cause XvShmPutImage to take longer.
any help is appreciated
(BTW, i'm running it on a 2Ghz P4 with a 32Mb nvidia go card and 512 Mb ram.)
