Tested:
  - VLC 2.0.3, libraw1394 2.1.0, libdc1394 2.2.0, kernel 3.6-rc7, udev 171, 
Gentoo Linux
  - miniDV camcorder JVC GR-D725E
  - IIDC (DCAM) webcam Apple iSight
  - VIA VT6306 based CardBus FireWire controller
  - Texas Instruments XIO2213A/B based PCIe FireWire controller

"vlc dv://" and "vlc dc1394://" automatically pick up the camcorder or
webcam respectively and display live video.  Sound of the DV stream is
played as well.  I did not try network streaming.  (Never tried it
before and did not figure out how to set up stream output.)

The VT6306 controller does not work very reliably:  For example, if VLC
is stopped and restarted with "kill -STOP $pid" and "kill -CONT $pid",
the DV stream is frozen.  This is a known issue between VT6306 and
current kernels which is also seen with some other capture programs; the
VT6306 does not properly restart its DMA after a period of inactivity of
the capture process.  The Texas Instruments controller does not exhibit
such a problem, as expected.

Somewhat older software revisions should work as well.  libdc1394 and
the VLC dc1394 are irrelevant for DV.
