Original commit message from CVS: * docs/plugins/gst-plugins-bad-plugins.args: Remove directsoundsink property doc as this sink use the mixer interface now. * docs/plugins/gst-plugins-bad-plugins.interfaces: Add interfaces implemented by Windows sinks. * sys/directsound/gstdirectsoundsink.c: * sys/directsound/gstdirectsoundsink.h: Remove directsoundsink property and implement the mixer interface. * win32/vs6/gst_plugins_bad.dsw: * win32/vs6/libgstdirectsound.dsp: Update project files. * gst-libs/gst/dshow/gstdshow.cpp: * gst-libs/gst/dshow/gstdshow.h: * gst-libs/gst/dshow/gstdshowfakesink.cpp: * gst-libs/gst/dshow/gstdshowfakesink.h: * gst-libs/gst/dshow/gstdshowfakesrc.cpp: * gst-libs/gst/dshow/gstdshowfakesrc.h: * gst-libs/gst/dshow/gstdshowinterface.cpp: * gst-libs/gst/dshow/gstdshowinterface.h: * win32/common/libgstdshow.def: * win32/vs6/libgstdshow.dsp: Add a new gst library which allow to create internal Direct Show graph (pipelines) to wrap Windows sources, decoders or encoders. It includes a DirectShow fake source and sink and utility functions. * sys/dshowsrcwrapper/gstdshowaudiosrc.c: * sys/dshowsrcwrapper/gstdshowaudiosrc.h: * sys/dshowsrcwrapper/gstdshowsrcwrapper.c: * sys/dshowsrcwrapper/gstdshowsrcwrapper.h: * sys/dshowsrcwrapper/gstdshowvideosrc.c: * sys/dshowsrcwrapper/gstdshowvideosrc.h: * win32/vs6/libdshowsrcwrapper.dsp: Add a new plugin to wrap DirectShow sources on Windows. It gets data from any webcam, dv cam, micro. We could add tv tunner card later.
