To develop applications using GStreamer for Windows we recommend using Windows10 or newer with Microsoft Visual Studio 2019 or newer. Older versions of eachmay also work, but they are not recommended.
GStreamer package includes C headers (.h) and library files (.lib) validfor any version of Microsoft Visual Studio.For convenience, property pages (.props) are also included which extremelysimplify creating new projects.
On Windows 8 and Windows 10, it might be necessary to log out and log back in to your accountafter the installation for the newly defined environment variables to be picked up by Visual Studio.
It is the application's responsibility to ensure that, at runtime,GStreamer can access its libraries and plugins. It can be done by adding%GSTREAMER_ROOT_X86%\bin to the PATH environment variable, orby running the application from this same folder.
So, typically, if your application can find gstreamer-1.0-0.dll,it will find the GStreamer plugins, as long as the installation folderstructure is unmodified. If you do change this structure in yourapplication, then you can use the GST_PLUGIN_PATH environmentvariable to point GStreamer to its plugins. The plugins are initiallyfound at %GSTREAMER_ROOT_X86%\lib\gstreamer-1.0.
In order to prevent accidental modification of the original code, and tomake sure Visual Studio has the necessary permissions to write theoutput files, copy the entire tutorials folder to a place of yourliking, and work from there.
Use the GSTREAMER_ROOT_X86_64 environment variable if you have installed GStreamer binaries for 64-bit platforms.Both GStreamer packages (32 and 64-bit) can be installed simultaneously, hence the separate environment variables.
This property sheet contains the directories where the headers andlibraries are located, and the necessary options for the compiler andlinker, so you do not need to change anything else in your project.
The tutorial's project files already contain all necessary property pages. When developing your own applications,the GStreamer documentation will tell you what library a function belongs to, and therefore, what property pages you need to add.
Applications built with Visual C++ 2010 depend on the Visual C++ 2010Runtime, which is a DLL that gets installed when you install VisualStudio. If you were to distribute your application, you would need todistribute this DLL with it (e.g. via the Visual C++ 2010 RedistributablePackage).This happens with every version of Visual Studio, and the Runtime DLL isdifferent for every version of Visual Studio.
The generated project file includes the two required Property Sheetsdescribed in the previous section, so, in order to link to the correctMSVCRT.DLL, you still need to install the Windows Device DriverKit and change the appropriate property sheets.
I'm trying to install GStreamer 1.0 on Ubuntu 12.04, the default GStreamer that comes with Ubuntu 12.04 is gst 0.10. I could see that I could download the GStreamer 1.0 source from gstreamer.freedesktop.org, build it and install it. But this installs only the gst plugins only, it does not install the actual required libraries like:
If you want to install gstreamer 1.0, you need to use the backports for Precise from the gstreamer developers ppa, which is the best source at the minute and the most 'official' developer ppa available.
This will install all the base packages and plugins that you require, and is fine to install, even though you also have the earlier version installed as well, although applications will not use gstreamer1.0 unless they have been built with support for it.
I did a standard install of gstreamer, it would get to qground control, but not mission planner. (On windows 10 _ 64bit) . (also latest stable versions of qgroundcontrol and mission planner).
I can only figure that is because of the gstreamer version.
So now I figure I need to install gstreamer version 1.9.2 on my raspberry pi.
but it seems like it would only install the latest gstreamer version. There are pages where you can download the version you need, but how do you install all the correct libraries and environment requirements?
I have had this working before on the same raspberry pi, I have no idea how i did it, i was following all sorts of blogs and installing all sorts of things, this time i am trying to do everything properly and document it. (i will happily make a video tutorial for this, and documents you can add to the main github guide book, as this is something that soaks up endless hours for newbies!).
ok ive found a straight forward install plan, unfortunately its still only getting to qgroundcontrol and not mission planner, but erghghgh im a bit over it now. Will just stream it to a gstreamer script so i can view the video.
GStreamer is installed as per the instructions (i.e. all offered packages) in C:\gstreamer. I've tried reinstalling both PTB and GStreamer and the problem persists. Any help/suggestions would be greatly appreciated. I'm running Matlab 2012a on Windows 10 Pro (64).
For my recording project I need to use a tool which needs a new version of gstreamer. I've seen that 1.6.3 is the last stable version of it but don't know if it's possible to install it on my system (ubuntu 14.04 / 4.1.6-040106-generic) if yes, what's the easiest way to install?
I could not find dependencies that satisfy ivorbisdec so don't worry about that one unless you really need it. Run ./configure again after installing dependencies and then proceed if you are satisfied.
There was a whole list of plugins not built here, I didn't even try to track down. If you have problems with GStreamer later on like if something doesn't work, you can check but I wouldn't bother here unless there are issues.
I am having trouble enabling gstreamer support for the opencv python package (cv2). gstreamer1.0 is running fine as a standalone and I have manually built the cv2 python package from the OpenCV sources.
ahh jeeez. I just took a bunch of time answering my own question. new users have to wait 2 days to do it though. I'll post it in my related stack overflow and make sure to link this post here, too. You're on point about your find! I had both WITH_GSTREAMER and WITH_GSTREAMER_0_10 set to ON during installation. Cmake seems to prefer the latter, but I don't have gstreamer0.10 installed. I am running gstreamer1.0 and thus must enable only the WITH_GSTREAMER option during cmake. Again, thanks for the immediate help =)
@berak is on point about his find in the comments! I had both WITH_GSTREAMER and WITH_GSTREAMER_0_10 set to ON during installation. Cmake seems to prefer the latter, but I don't have gstreamer0.10 installed. I am running gstreamer1.0 and thus must enable only the WITH_GSTREAMER option during cmake.
Hi I am trying to run a have a gstreamer stream run on OBS studio. I followed all the guidelines in downloading the plugin but, i add the stream settings but nothing shows up on gstreamer. Both cameras show up QGC though not sure what the issue is.
i havent download the msvc installer before. I though it would install along with qgc. Ive been trying to get a camera stream to obs studio but for sm reason even after the plugin shows in and i set a pipeline i can see the feed. But if i try the same thing on linux it works well.
The simplest way would probably be to run sudo dnf upgrade gstreamer-plugins-bad-freeworld --allowerasing and it should them uninstall the conflicting packages. As Chris said the best fix would be for rpmfusion to fix the conflicts. This is part of fedora trying to improve multimedia support within the fedora distro where previously they were mostly dependent upon the 3rd party repos to support almost all multimedia codecs.
I removed the package gstreamer1-plugins-bad-freeworldfrom rpmfusion repository with Yum Extender and problem was solved. This was only gstreamer plugin package from rpmfusion in my system. Updated versions are from updates repository.
I tried to remove the offending rpm but dnf also wants to remove several items of installed software with it, as well as quite a number of python files used by other programs! Nothing here so far posted works. Any other suggestions?
Note:
I also tried with the reference multimedia image: Toradex Download Links (Torizon, Linux BSP, WinCE and Partner Demos) Toradex Developer Center and the plugins are correctly installed inside the /usr/lib/gstreamer-1.0/ folder.
Should video display via GStreamer work?
I have a Mission Planner installed. In Video I have the option Herelink but does not display anything
I do have Video on my desktop when running QGroundcontrol
@champ8242 Sorry for my last reply. Download and install the latest version of gstreamer only solve the gstreamer error, but cannot get the HereLink video to be played on MP. At least this is my current situation.
Thank you for your input and update. I have been busy debugging the situation also with your remark of the download. I immediately checked the version of GStreamer I had installed and it is/was the latest 64bit for Windows 10. I will report later in this thread my findings
which you could have found by doing a search for gstreamer-app-0.10.pc in package contents on packages.ubuntu.com or with apt-file search, or by running the whole configuration process within auto-apt run.
