Without zero copy, there should really no value in using direct mode
transfers. It is probably even slower than normal copy mode.
In the even that the capture device do not support standard transfers, VLC
should automatically detect the problem from hardware parameters, and
select the correct mode with no a command line option. I do not know if
there are such devices, and I would expect that ALSA plughw would work
around the problem if it exists.
