Original commit message from CVS: * configure.ac: * sys/Makefile.am: * sys/dshowvideosink/Makefile.am: * sys/dshowvideosink/README: * sys/dshowvideosink/dshowvideofakesrc.cpp: * sys/dshowvideosink/dshowvideofakesrc.h: * sys/dshowvideosink/dshowvideosink.cpp: * sys/dshowvideosink/dshowvideosink.h: Add a new win32 videosink. Uses the DirectShow renderers for high-performance video rendering on win32. Currently only supports some YUV formats. Rank PRIMARY, since it's much more useful for the common cases that the directdraw sink (which only does RGB).
