I am trying to execute the "Basic tutorial 5: GUI toolkit integration" source
from the documentation.
https://gstreamer.freedesktop.org/documentation/tutorials/basic/toolkit-integration.html?gi-language=cThe GTK and Gstreamer setups is done as below:
OS : Windows 10 64-bit
1. GTK+3 is installed using vcpkg
2. Gstreamer (ver 1.16) is installed using the official gstreamer downloads
3. Gstreamer libraries are added to the the environment variables using
GST_PLUGIN_PATH
4. The source code is setup in visual studio 2019
5. Gstreamer property sheets are added
(Note : gstreamer-video-1.0 and gstreamer-1.0 props are only added,
gtk+-3.0 is integrated to Visual studio using vcpkg)
The code compiles and executes, but the output is not as expected. GUI is
displayed, but the gstreamer pipeline is played in a separate sink windows.
There are several errors in the console.
GLib-GObject-WARNING **: 11:43:34.893: ../gobject/gsignal.c:2523: signal

The errors seems like Glib-GObject is unable to process the signal_connect
for GTK objects. I am able to execute GTK samples separately without adding
the gstreamer compiler or linker libraries to visual studio.
When I manually add the linker and compiler dependencies of GTK and
Gstreamer in Visual studio, I get the signal_connect errors for gstreamer
objects.
eg: signal 'media-configure' is invalid for instance '0000026441B40280' of
type '(NULL)'
How can I fix the GObject reference issue ?
At run-time, how is the GObject referenced by GTK and Gstreamer code ?
I am not an expert in visual studio and C therefore finding it hard to
resolve the library/dll reference issue.
