[pwc] Multiple webcams

[Gilles GIGAN]

Hi all,
I just wanted to confirm whether or not you can use more than one webcam at
the same time on the same computer, all using the same pwc driver instance ?
So far, my tests with 2 webcams have failed. Capture from each is made via
mapped-memory, not read/write. Accroding to what I found, It seems capture
works on only one webcam at a time. All other block on ioctl
(VIDIOC_QUERYBUF) until the working capture thread close its device file. Is
this correct ?
I did google a bit before posting, and I came across two users with the same
issues (http://ml.osdir.com/drivers.pwc/2006-08/msg00002.html) , but that
was back in Aug 2006, and I wanted to know if things have changed a bit
since then.
Thanks
Gilles
