I go through various forums. But i don't understand how to integrate SDK as well as is it possible to integrate BlackMagic SDK in QT Application?
As long as it is a C/C++ SDK the process is pretty straight forward.
Or alternatively if possible (i don't know how the SDK is built up) embedd it into your application by adding all it's source files to your project. But this might cause other side-effects. Better link against it (see the link i've posted)
