Dear V4L Gurus,
I would like to grab a single frame at a time of composite video to my
Linux PC, and would greatly welcome any advice on the best way to do
this. Sorry if this is off-topic here, please let me know where I should
be posting instead if I am off base(:-)).
1. Are there any frame grabber cards that work "out-of-the-box" under any
Linux kernel version that could accomplish this simple feat? (If one
worked under the RH7.0 that I have already installed, that would be even
better!)
2. Can anyone point to software that works with the v4l interface, which
can easily accomplish this task, or should I just use the v4l API? I don't
need any video compression, if that matters.
3. Any recommendations for frame grabbing devices that could be used with
a laptop running Linux, to grab a composite video frame (speed is not an
issue, so I assume I could even use a USB port). I can't use a webcam, the
signal is coming from an existing camera. The Iomega Buz looks attractive,
but I see from Iomega's website, that they are no longer available from Iomega?
4. Do I need to patch a 2.2.x kernel with the big_physarea patch for a
DC-10+ or LML-33 board? I have been mucking about with a LML-33 board with
RH7.0, as well as a DC-10+ under a vanilla 2.2.19 kernel for an alpha, and
they seem to work without the patch.
Any comments, criticisms, things to try, things to avoid, etc. would be
very much appreciated.
Thanks in advance!
