RE: good quality webcam for linux?

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



Here's what I have used. All of this pretty much worked out of the boxes
(all of them ;-):

- SuSE 8.0 (kernel 2.4.18) This distribution has a lot of the video stuff
bundled
- A generic OHCI FireWire PCI card
- A Sony PC1 DV camcorder
- A Dazzle Hollywood DV Bridge. This is a $300USD firewire <-> composite/S
video (and audio) converter box. Works real well.
-
I hooked up the firewire devices to the PCI card (one at a time) and
captured video with dvgrab. I used mjpegtools to convert the video to a VCD
compliant MPEG file. I used a regular Hi8 camcorder to feed video to the DV
Bridge.
The only trick was that I had to insmod ieee1394.o, ohci1394.0 and raw1394.o
to get dvgrab to be happy.
I can't keep track of whether any of the stuff I use is considered part of
v4l.
Dvgrab produces gobs of data (3600000 bytes/sec). You need a fast machine to
keep up with this. In my case I work with 5 minute video snippets. That's
approx 1 gig from dvgrab. I immediately squeeze that down to 50 meg before
burning a VCD. That's a 20X reduction. I tried a few analog capture cards
but they didn't work that well so I picked this rather roundabout way of
doing things.

what I'm really looking for is a way to use a camera that I already have,
which has svideo and component outputs, as a v4l source on a laptop. It
seems like firewire would be the best way to get the video in, but I
haven't discovered any solutions that sound like they would work yet.
