[streaming] Re: WebCAM Device Recommendations

[Richard Ham]

Chen,

I believe the Quickcam Pro 3000 and a number of other camera's use the
driver located at http://www.smcc.demon.nl/webcam/ . AFAIK, this
driver works well with vls and vlc. This camera appears to be quite
robust and the driver seems to be fairly flexible.

The Quickcam express camera uses the driver(s) located at
http://qce-ga.sourceforge.net/  - this driver, while working well with
a number of other v4l applications, doesn't work well with vls when
using a quickcam express camera (other cameras may work, but the qe
didn't). AFAIK, this is a palette issue and due to the nature of the
v4l layer as much as anything else.

As always, YMMV :)

Regards,

Richard
