[V4L] getting started on v4l programming

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



Hello,
	I used to work with v4l2 and bttv2 on a bt848 based
capture card. Now I need USB webcam III support on 2.2.16 (USB
back-port and Mark McClelland's ov511 driver). As far as I know
there's no v4l2 interface for ov511 and I have to switch to v4l.
My question is: Is there any simple and complete piece of code,
like Bill Dirks' xcaptest.c, to be used as a v4l tutorial?
	I have already ``talked'' to ov511 through v4l, and I
posted my experiences and questions in my first email to the
list. It's entitled ``usb webcam III and v4l on redhat 6.2
(2.2.16)'' and archived in 2000-November.
	I would appreciate any kind of tutorial (shorter
than xawtv sources, please) on setting capture modes (e.g.
YUV420, RGB565, etc.), capture sizes (e.g. QCIF, CIF, etc) and
managing capture buffers.

Thank you in advance,

Matias.
