Hi, I'm currently working on a driver for a web cam that has 7 alternate settings for it's only interface, the only difference between them being the packet size of the iso end point. I see in the konicawc driver (which has a similar set up) that this is some how related to the frame rate that the camera produces, with a smaller packet size resulting in a lower frame rate. Is this a standard way of doing things?
This doesn't really make sense to me, I keep thinking that a smaller packet size will only mean that there are more packets per second, or is this a fixed rate for USB? Also, this webcam can either output raw sensor data (YUV) or JPEG. I'm using the usbvideo frame work, and I don't see any support for compression in its ioctl methods. Will this need to change if I want to continue to use the usbvideo framework? Sorry in advance for any slapping of foreheads, I'm new at this. So far I have the LED blinking on the camera, and I can change the various settings that it has, but no picture as yet :) Regards, Nigel ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
