I have downloaded pond.dv   video sample file from
http://libdv.sourceforge.net/

Then:

with lastest gstreamer git, on linux

[fail] gst-launch-0.10 filesrc location=pond.dv ! ffdemux_dv ! ffdec_dvvideo
! xvimagesink
[fail] gst-launch-0.10 filesrc location=pond.dv ! dvdemux ! ffdec_dvideo !
xvimagesink
[fail] gst-launch-0.10 filesrc location=pond.dv ! ffdemux_dv ! dvdec !
xvimagesink
[success] gst-launch-0.10 filesrc location=pond.dv ! dvdemux ! dvdec !
xvimagesink
[success] ffplay pond.dv

So "ffmpeg" can play it but "gst-ffmpeg" cannot.

It seems that libdv cannot be compiled with mingw:
see: http://www.nabble.com/dv-support-on-windows-td20035798.html

(note that there is a win32 port for pthread)
