So id tried to make device nodes for dv1394 and ieee1394 by
mknod -m 666 /dev/dv1394 c 171 34
mknod -m 666 /dev/ieee1394/dv/host0/PAL/in c 171 34

I've tried to send many different messages to [pix_video] but it doesn't
So, i downloaded the source from gem 0.90 and tried to read it (I'm not
familiar with C/C++) and there is one thing which i have detected:

if gem is recognizing that there is dv it should write the message “ieee1394
for linux”, but it doesn't

The message only appears if HAVE_DV is defined, and HAVE_DV when HAVE_LIBDV
is defined but i couldn't find where HAVE_LIBDV is defined in the source,
and most interesting thing why HAVE_LIBDV or rather HAVE_DV is not
