Hi-
anyone have a suggestion for 'best' all-around Video capture card?
My only requirements-
a) good vl1 (and hopefully vl2) driver support
b) relatively inexpensive


There is a project I'm scoping to capture video from vhs and possibly 
video-camera (firewire). Any help would be appreciated, as I am new to 
using video-capture devices under linux. 
Thanks.

For cheap passable quality any of the supported BT848/878 cards. They just
work. You want a bit of cpu power for software mjpeg/mpeg1/whatever encoding
in real time.

Hi!

I've been trying to answer the same question myself. This is what I have
determined so far, in terms of the options available and their various
pros/cons. I need the framegrabbing gear for robotics and computer
vision applications:

1) For ATI based cards there was (is?) a project called gatos. While it
seemed to me that it was possible to make this run with a number of
older ATI cards, support for newer cards wasn't there, and the project's
focus seemed more on watching TV than video capture. I also think they
went their own way rather than using v4l. In the end it did not seem an
attractive option for me.
2) There's 'QuickCams'. The Philipps VESTA series, the Creative Webcam
II and recently also the Logitech QuickCam Express and Web are more or
less well supported. There's v4l drivers, and the cameras are very cheap
($40 or so for a Logitech QuickCam). USB is a convenient interface (plug
n play, hot swapable, and no nasty power bricks for the cam). However,
the image quality of these cams is proportional to their price, ie very
low. Still, for many applications this might be the way to go, I feel,
and for the price it can't hurt to try.
3) There's IEEE1394, or FireWire. There's a large number of supported
host adapters, some sell for less than $200. If you have an OHCI
conformant host adapter, chances are it will work pretty well. See
http://linux1394.sourceforge.net/ for more info. There's a large number
of cameras you could use, from MiniDV handycams to security type
cameras. Prices can range from a couple of hundred to several thousand.
At the moment, the low level 1394 support seems to be well in place, but
the video drivers are more 'raw'. In particular I don't think there's
v4l support yet, although there are early programs for grabbing DV. This
seems like a good option to me if you're writing your own code and are
prepared to be a bit of a pioneer. There's no doubtin my mind that
there's future in this, and drivers will become a well supported part of
the kernel.
4) There's the bt848 based stuff. This seems like a cheap option that is
likely to work well, if you get the right hardware. For my purposes it
seemed a bit TV oriented, and none of the supported cards really were
frame grabbers in their first role.
5) As far as I was able to ascertain the only framegrabber card in
active production with support under linux is the Matrox Meteor II. The
Matrox framegrabbers have a reputation for quality, but the price is not
low: I recon $600 or so for a plain Meteor II, and that's without a
camera. The Meteor II Multichannel is sadly not let supported under
linux. A german company maintains v4l2 drivers for the Meteor II. 

That's my 2c, but I'd sure like to hear other people's opinions/finds.
Does anyone have a recommendation for framegrabbing under linux, using
current kernels and currently available hardware?

Thanks,

Richie

They are good frame grabbers. Bus mastering PCI DMA engines, multiple inputs
including svideo. Don't make the assumption that cheap=crap

In this case cheap == volume

There are people studying bees with bt848 cards 8)
