Hello all, I'm writing a program that captures images from a bttv video capture card and processes them then outputs to the screen and i need real-time performance. Currently I'm using XImages to display on screen but i want to use MIT-SHM extension and XShmPutImage. My problem is that the data is coming from mmap()'ed buffers and i don't know how to get it into the XImage without doing memcopy. Currently I use
XImage->data = &buffer[i]; XPutImage(... Can i do this with SHM or can i mmap the same segment as i use for a SHM XImage? Or is it faster with memcopy? THanks Brian _______________________________________________ Xpert mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/xpert
