cam max width and height
Hi, I am using linux 2.6.26.3. I connected "microsoft live cam" and its max supported resolution is 1280x800. If I use VIDIOC_G_FMT, fmt.fmt.pix.width, fmt.fmt.pix.height returns 640x480. How to get the maximum supported resolution??

Re: Need Info
Hi, It is observed that Lifecam transfer type is Isochronous and ISP1362 driver does not support this. Is there any driver patch that supports Isochronous transfer?? Please help me in this regard.

Re: cx88 audio input change
In Linux cx88 driver, is it possible to stream audio only without video Risc engine running? If so, what tools/players and commands can I use to stream audio only from cx88 card? I appreciate for all your help.
