It'll output raw 720x480 4:2:2 component (Cb-Y-Cr-Y packed) if you're using StdoutOutput. You should be able to view it with something like...
./playoutd | mplayer -demuxer rawvideo -rawvideo ntsc:uyvy -
Of course you'll have to install mplayer from your distribution's package repository before this will work.
