not necessarily.
you have compiled 5 plugins, but some of them might not have enabled
their code.
e.g. if configure cannot find libdv, then you will end up with a bare
gem_videoDV4L.so, that basically does nothing....

see above.

no, dc1394 uses idc (industrial video over ieee1394), wherase dv4l uses
IEC 61834 (aka: consumer a/v over ieee1394)

did you follow the steps in plugins/videoHALCON/README.txt that say:
<snip>
probably this won't work, with Gem complaining that it cannot find
"libhalconcpp.so" or similar.
in this case should tell the linker where to find the halcon-libraries,
using
the LD_LIBRARY_PATH variable:
$ LD_LIBRARY_PATH=${HALCONROOT}/lib/${HALCONARCH} pd -lib Gem
should do the trick.
