Problems building QtGStreamer release build on Windows

Hi Dinesh,

Good to hear that it can work.

I tried your cmake command line, but I get the same results - no
import entries in the QtGStreamer DLLs - which means that they don't
load the gstreamer dlls and so I get a crash (access error) when I
call QGst::init(). All works fine for the debug builds, which is even
more confusing.

Here are the steps I used to build it (the QtGStreamer source is in a
directory called qtgstreamer):

md build-release
cd build-release

cmake -DCMAKE_BUILD_TYPE=Release

cmake --build . --target install --config Release

How does that compare to your build?
Which version of Visual Studio are you using?

Many thanks,
