main modules and their uses in vlc
===================================

DirectShow(win)+ Directsound===v4l2(lin) + alsa

gstreamer defines interfaces and contexts for all components of A/V pipe
directshow does the same on windows
v4l and alsa becomes a sub component of gstreamer
vlc uses v4l2/alsa interface directly for A/V
gstreamer plugins are interfaces that wrap around v4l2/alsa apis and make them
consistant with gstreamer specifications
so if vlc was not written in adherence to gstreamer spec, vlc is not a gstreamer app
