Original commit message from CVS: Patch by: Ole André Vadla Ravnås <ole.andre.ravnas@tandberg.com> * gst-libs/gst/dshow/gstdshowfakesink.cpp: (CDshowFakeSink.CDshowFakeSink): * gst-libs/gst/dshow/gstdshowfakesink.h: (CDshowFakeSink.m_hres): Fix crasher in constructor due to the base class's constructor not necessarily being NULL-safe (depends on the SDK version used apparently; #492406). * sys/dshowsrcwrapper/gstdshowaudiosrc.c: (gst_dshowaudiosrc_prepare): * sys/dshowsrcwrapper/gstdshowvideosrc.c: (gst_dshowvideosrc_set_caps): Fix a couple of MSVC compiler warnings (#492406).
