#include <avcap/windows/DS_Tuner.h>
Inheritance diagram for avcap::DS_Tuner:
This implementation uses the PROPSETID_TUNER property-set which is defined in the library kstvtuner.ax which can not be linked with gcc. It thus can not be used under mingw, but only if build with Visual-C++. So the mingw-build library misses this tuner-implentation.
There are only three states of signal strength: signal present, signal not present, signal not determined. Because of this limitation the method getAFCValue() is not implemented.
