Integration of GStreamer in QT application on Windows using MinGW

[d***@tiscali.it]

Hi,

I'm interesting in the integration of the gstreamer library
on Windows 7/8 platforms using QT and the MinGw compiler. Do you think
this is possible? Could you give me some hint to let me start in this
integration?

Best Regards

Daniele Santanché

Hi
It is doable quite easily.
You just have to download the gstreamer binaries + dev files, install it.
To play the video in a QT widget, I used the D3DvideoSink, using the video_overlay interface to give the video sink the widget in which to render.
I don’t really know about the MinGw compilation as I used Visual’c compiler, but any way as both Qt and GStreamer are built using minGw, this shouldn’t be an issue.

Good luck
Eric T

yes it is doable. I am developing such application myself. You can use
precompiled binaries from gstreamer page and Qt for MinGW. But you need
get rid of taglib plugin. It is because taglib is C++ code. Problem is
that gstreamer and Qt is compiled with different version of C++
exception handling runtime. So just delete taglib and gstreamer becomes
pure C library which can be used freely between different MinGW versions.

more information about different C++ runtime

Hello! I also try to integrate GStreamer with Qt but I am a beginner.

I need to integrate Qt 4.7.4 (MinGW 4.4.0 x86 compiler) with GStreamer on
Windows (Windows 7 x64 installed). The application must be x86 compatible.
I downloaded the latest GStreamer packages: gstreamer-1.0-x86-1.2.4.1.msi,
gstreamer-1.0-devel-x86-1.2.4.1.msi and
gstreamer-1.0-x86-1.2.4.1-merge-modules.zip.
I installed the first and second package but I don't know what to do with
gstreamer-1.0-x86-1.2.4.1-merge-modules.zip.
I created a console application and modified the .pro file by adding the
following lines:


As a result I receive the following error... (application work fine without
lines given above)


main.cpp:


I also tried to delete all files "taglib" but it doesn't work...

Please, help me!
How to install these GStreamer packages?
How to configure the Qt project? It would be nice to get the example of .pro
file or the entire project.

Sorry, but the problem still remains...

I've installed the gstreamer-1.0-x86-1.2.4.1.msi and
gstreamer-1.0-devel-x86-1.2.4.1.msi to D:/gstreamer.

console.pro:


main.cpp:


Error:


The full output:


I am doubtful what I ought to do... I urgently need to start the development
of cross-platform VoIP application.

You could use msys2 packages instead. For me it was a painless experience.
Used gstreamer+freeglut on windows7..
