Re: image capture speed up?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



It's good to know that `Creative labs ct6840' is
capable of compression. Do I need to find any
API (like pwc-ioctl.h for Philips WebCam) in addition
to upgrade the ov511 driver? 
What kind of fps can I reach if I stick to this model
of WebCam?


Thank you.
