What generic webcams drivers do you people use? I found
macam, IOXperts and the one that comes with my particular
WebCam. All give different results as far as some APIs are
concerned (e.g. they behave differently on VDSetDigitzerRect
and SGSetVideoRect calls). Being at the early stage of research
I want to protect myself from future errors, so I want to
try different drivers to see what other differences I may
encounter. So, what else do you use?
[For those curious I am struggling with what seems to be
mission impossible so far: trying to get info out of
SequenceGrabber/VideoDigitizer/Camera itself/Whomever about
supported resolutions, supported formats and supported frame
rates. Without any response from the list I was hoping to
do the next best thing: ok, asking about list of particular
values looks too much close to asking about family silver,
gimme at least the _ranges_ of supported values (e.g.
resolutions from 100*100 to 640*480, frame rates from
10 to 25). But I can't think of reliable way to do even this
(e.g. DigitizerInfo.maxDestWidth/Height may report arbitrary
large values like 32000 which looks unbelievable.]
[BTW, I've looked at macam sources and found interesting APIs like:
// Provide feedback about which resolutions and rates are supported
//
- (BOOL) supportsResolution: (CameraResolution) res fps: (short) rate
which is exactly what I need, though I don't see how these could
be called with the generic (not macam) drivers.]

However, I would rather know the supported resolutions in advance

list of supported resolutions for each video source that I discover.
There is no existing API to report such information currently in
place, neither for the SequenceGrabber in general, nor the lower
level QuickTime IIDC Digitizer.
I found this in archives. Did anything changed in this area since
then?
