[linux newbie]

Hi,

On my embedded PXA255 platform, we have working USB module. ISP1362 is the
controller. Recently we want to integrate Microsoft Lifecam Cinema webcam
and want to take still images.

Linux kernel is 2.6.26.3 and we enabled V4L2 and UVC class drivers. On
plugging the Cam and querying the proc and sys file system, I can able to
view cam details.

I want to capture the frame (preferably in jpeg) and write to a file. Is
there any example code for that? I went through the below web page
http://v4l2spec.bytesex.org/spec/capture-example.html, but if you can
suggest some more example, it will be of great help to me.

Thanks

Hi,

the video4linux mailing list is all but dead and has been superseded by
the linux-media mailing list (Lmml). I've cc'ed the Lmml with this reply.

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.
Thanks
