Hi, I'm writing a video processing application under linux and windows. I'm using an ov511 driver under linux (I have a creative pro, usb camera), and dx under windows. I have the feeling (I haven't finished investigating) that the windows version is running much faster (perhaps 3 to 4 times the frame rate). Do you know why this could happen ? Is it something to do with the ov511 driver, or usb driver, or do I have a bug in my code ? Thanks for your time & help, Alok.
