Original commit message from CVS: * sys/dshowdecwrapper/gstdshowaudiodec.cpp: * sys/dshowdecwrapper/gstdshowaudiodec.h: * sys/dshowdecwrapper/gstdshowfakesrc.cpp: * sys/dshowdecwrapper/gstdshowutil.cpp: * sys/dshowdecwrapper/gstdshowutil.h: * sys/dshowdecwrapper/gstdshowvideodec.cpp: * sys/dshowdecwrapper/gstdshowvideodec.h: Prefer known-good filters, create directly by GUID if possible, fall back to creating highest-merit filter otherwise. Fixes playback with random dshow filters installed in some cases.
