GStreamer SDK is a program that allows you to create world-class multimedia applications. You may want to check out more software, such as GStreamer, Medialooks MFormats SDK or VintaSoftImaging.NET SDK, which might be similar to GStreamer SDK. Gst-python git repository. Reference documents for GStreamer and the rest of the ecosystem it relies on are aavilable at laza'sk GitHub site. The main GStreamer site has Reference Manual, AQ,F Applications Development Manual and Plugin Writer's Guide. This tutorial targets the GStreamer 1.0 API which all v1.x releases should follow. Trusted Windows (PC) download GStreamer SDK 20.13.6. Virus-free and 100% clean download. Get GStreamer SDK alternative downloads.
Update. Windows binaries of GTK+-3.14.0, Gstreamer-1.4.4, Python3, pygtk3 gobject-introspection PyGObject (aka PyGI)are available from here, so this guide is not necessary (unless the latest version of Gstreamer without PyGI is desired)
This handy little guide catalogues the adventures of building a minimal Windows version of GStreamer-1.0 on Linux, (without PyGI, which can only be built on Windows). GStreamer-0.10 is end-of-life, so we won't be discussing that. For those who need the Python stuff, but do not want to download the above binaries, Start with building Python3 on Windows. Visual Studio 2010 Professional Edition and Python 2.7-ish is required to build 64-bit Python3. Express Edition can do 32 bit. Now away, go!
The rest of this guide is for Fedora Linux. What good is a Windows version of Gstreamer on Fedora? We can use the comfortable Linux desktop and cross-build system to buid apps for both Windows and Linux, that's why. And then we can test our apps in the wine windows emulator, and make sure everything works the same without needing to use a separate Windows machine.
Fedora Packages
Geting mingw64. This is not the most exhaustive, nor the most minimal install of Mingw64. It's simply what we had on our system.
yum -y install mingw64-binutils mingw64-bzip2 mingw64-cairo mingw64-cpp mingw64-crt
Notice: Do not use root or sudo administrator permissions for any of the make install steps. This howto installs them to the default .wine folder in the user's $HOME directory, which should not require any special permissions. Do not use root or sudo to run wine, nor to do any tests. That's now how any of this works. As a matter of fact, it would be better to log in as an unpriviliged dev user, or chroot sandbox.
This is just a temporary test build walkthrough. Of course there are no guarantees, but if followed correctly, no changes should happen to anything on the Linux development platform. For something more permanant, you could go ahead and re-compile some of these dependencies into Linux's Mingw64 itself from a different shell, and using mingw64-make but that is beyond the scope of this particular agenda.
This will set up a 'safe' cross-build environment.

Q. How do you know where to download source packages from?
A. Get 'rinfo' for Fedora Linux. Append to .bashrc to make it permanent.
alias rinfo='rpm -qi --nodigest --nosignature'
Usage: rinfo [package name]

I am looking into gstreamer as a means to choose a video device from a list to feed it to an opencv script.
I absolutely do not understand how to use gstreamer with python in windows. I installed the Windows gstreamer 1.07 binaries from the gstreamer official website. However, I could not import the
pygst and gst modules in python.
I checked the gstreamer installation, and there seems to be no
pygst.py provided. There is however a file named gst-env that contains paths for environnement variables (that were not added to the system variables on installation. I checked.
Other questions on the same problem here and here, for example, do all use the winbuild versions of gstreamer. Why is that so?
I am totally lost on this one.
Edit
Ok, I managed it using the SDK for Gstreamer 0.10 (in which there is a
pygst.py ), but is there not a way to use the Gstreamer 1.0 series, since 0.10 is “end-of-life”?
Answers:
This is a bit late, but hopefully it will help.
The easiest way to use GStreamer 1.0 is to download the latest version from:
http://sourceforge.net/projects/pygobjectwin32/files/
This will install Python (2.7 or 3.3) modules and, optionally, GStreamer with plugins.
However, if you already have GStreamer 0.10 SDK (from docs.gstreamer.com/display/GstSDK/Home) and old installation of GStreamer 1.0 somewhere, there might be some problems with running Gstreamer 0.10 Python programs, like ImportError: DLL load failed etc. Here’s my detailed setup for everything:
Installation of Gst 0.10 SDK and Python modules
Installation of Gst 1.0 and Python modules
Edit:
If you use both GStreamer0.10 and GStreamer1.0 it’s better to create a separate virtual environment for GStreamer0.10 and put .pth files in its site-packages directory. See my comment below.
HTH,
Tom
Answers:
Step 1: Windows 8.1 64-bit
Step 2: Download and Install Python
Step 3: Download install Python bindings for Gstreamer 1.0
Step 4: Run this code
Step 5: You have to wait 10 minutes, to see a result similar to following.
Because it takes time for some reason
Answers:
Gstreamer Download
The installer from http://sourceforge.net/projects/pygobjectwin32/files/ should works for the test case that Tom gave. Try to match which plugins installed by pygi installer with the one from official gstreamer.
Gstreamer Sdk Windows 10
The installer try to be a “portable and private” installation for each python without registry/environmen vars changes.
Gstreamer Sdk Runtime Windows 10
My note about the runtime dlls, it’s recommended not to mixing the runtime cause the one from pygi is made specifically for python a.k.a linked to msvcrt preferred by python, and use stat() convention that used by python too. If a public api such glib’s stat() use different convention than other dll then a runtime mixing could lead to a silent crash. Other than that it may works fine though.
