Build GStreamer on Windows. And augmenting them to the end of building GStreamer-1.0 (1.8.0) on Windows. (which may be a manual download/install for earlier. Install GStreamer OSSBUILD in Windows 8. Download and install. Download and install. Make sure to disable the. Now your GStreamer should be ready. The second command will take a long time and generate a lot of output. If the download fails, read below on Download Problems. Pelles C is a complete development kit.
We’re big fans of GStreamer, a very good open source multi-media framework supported on almost every platform conceivable, including Linux, OS/X, Android, iOS, and even tiny clients like Raspberry Pi. Recently, we’ve needed to use GStreamer on a couple of Windows projects. Because we use advanced features of GStreamer, like multiple synchronized video feeds with synchronized audio, we want to be able to build the Gstreamer libraries from source, in case we uncover a bug under advanced scenarios that might affect our client. Unfortunately, building GStreamer on Windows is fairly complex, and the available on the web are woefully out of date.
In general, you should avoid GStreamer.com since that site is no longer maintained by its parent company and use gstreamer.freedesktop.org instead. I recently worked through the legacy instructions, updating, correcting, and augmenting them to the end of building GStreamer-1.0 (1.8.0) on Windows.
The end result was a successful build of the GStreamer Windows MSI and merge module release artifacts. (A thank you to the current maintainers of GStreamer, who provided helpful advice along the way.) Building GStreamer on Windows is not for the faint of heart! But if you need to build it from source, these directions should help you out. Note that the software gets built in the Unix/POSIX-compatible MingGW/MSYS subsystem for Windows, so the instructions below assume at least some basic familiarity with Unix conventions.
Prerequisites This was tested on:. Windows 10 Professional.
Windows 7 Professional. Using Visual Studio 2015 Community. Using Microsoft Windows SDK/DDK 10 The below assumes you are on 64-bit, you’re building for 64-bit, and your Windows username does not contain spaces. Git Git can be added as part of VS 2015, or installed standalone. Microsoft Visual Studio.
These instructions used Visual Studio 2015 Community. Windows SDK 10 (which includes DDK 10).
Should work with SDK/DDK 7.1 or later (which may be a manual download/install for earlier versions of VS). Visual C.
Add as part of VS 2015 (Tools 1.x + Windows SDK 10) Note that the build does not use the Microsoft C/C compiler, but will need the Visual C libraries installed Downloads Needed (if not already installed, e.g. Integrated in VS) – Windows Installer: msi – Win64.exe (note: this will be renamed/copied later) – wix35.msi INSTALLATION STEPS. Install Visual Studio 2015 Community (or greater) – Make sure to add prerequisites in the components dialog – You can try using an earlier version of VS. Install Python to C: Python27 – Install for all users – Add Python.exe to Path. Install CMake – Add CMake to the System Path for all users – Suggested to install to C: CMake. Install Wix – You may get a warning that Votive cannot be installed to Visual Studio; this is harmless. MinGW/MSYS – This installation is quite involved, please follow the steps carefully – The later Cerbero build steps will automatically download the components of MinGW/MSYS that it needs, so you don’t need to worry too much here.
Install MinGW/MSYS Installation Manager. When the Installation Manager opens at the end, select following items in the “Basic System” – MinGW-developer-toolkit – MinGW32-base – MinGW32-gcc-c – msys-base – Click Installation Apply Changes – Click Apply. This will take many minutes to finish. YASM. Copy the YASM file you downloaded earlier (example name below) to yasm-1.3.0-win64.exe to C: MinGW bin – Rename to yasm.exe.
Make a shortcut icon on the desktop or taskbar or start menu: target: C: MinGW msys 1.0 msys.bat Run as administrator When you run this (as administrator) for the first time, it will create: C: MinGW msys 1.0 home This is where you will add a.profile file and where you will build Cerbero. NOTE: it is not known if the MinGW subsystem accepts Windows line endings It is suggested you use Notepad (or similar programmer editor) and set EOL (line endings) to Unix if you edit files in MinGW (use menu Edit EOL Conversion Unix). Create fstab.
You can copy: copy C: MinGW msys 1.0 etc fstab.sample to fstab Make sure it has this line enabled: c:/mingw /mingw. Create a file in /.cerbero/cerbero.cbc with the following lines:. NOTE: Parallel builds do not work (as of 1.8.0), so don’t enable that option Import os from cerbero.config import Platform, Architecture, Distro targetarch = Architecture.X8664 You must now set up the following inside your C: MinGW installation. (run the msys shell as Administrator). create a /.profile file: $ echo “export PATH= ” $PATH:/c/Python27 ”” /.profile $ echo “alias cerbero=‘/cerbero/cerbero-uninstalled’” /.profile.
Set wget to not check certificates: $ echo “checkcertificate=off” /.wgetrc Git Config. You need to set up the following items otherwise they halt the build process. NOTE: Git run inside the MinGW shell doesn’t pick up settings from Git Windows $ git config –global user.email “you@example.com” $ git config –global user.name “Your Name” $ git config –global core.autocrlf false Cerbero and GStreamer The following basic steps will be done to build a specific version of GStreamer. The recipe files in the version of Cerbero you check out will by default build the same version of GStreamer. (Cerbero and recipe files are beyond the scope of this section.) Note that the entire process can take MANY hours; be prepared!
Quick search. What are wheels, pip and wheel In Python, packages such as Kivy can be installed with the python package manager,. Some packages such as Kivy require additional steps, such as compilation, when installing using the Kivy source code with pip. Wheels (with a.whl extension) are pre-built distributions of a package that has already been compiled and do not require additional steps to install. Essentials of strategic management chapter 4. When hosted on one installs a wheel using pip, e.g. Python -m pip install kivy. When downloading and installing a wheel directly, python -m pip install wheelfilename is used, such as.
Warning Using the latest development version can be risky and you might encounter issues during development. If you encounter any bugs, please report them. Snapshot wheels of current Kivy master are created on every commit to the master branch of kivy repository. They can be found.
To use them, instead of doing python -m pip install kivy we’ll install one of these wheels as follows. Perform steps 1 and 2 of the above Installation section.
Download the appropriate wheel for your system. Install it with python -m pip install wheel-name where wheel-name is the name of the renamed file and add deps to the PATH. Kivy examples are separated from the core because of their size. The examples can be installed separately on both Python 2 and 3 with this single wheel:. Kivy’s dependencies We offer wheels for Kivy and its dependencies separately so only desired dependencies need be installed.
The dependencies are offered as optional sub-packages of kivy.deps, e.g. Currently on Windows, we provide the following dependency wheels:. for audio and video. and/or for OpenGL. for control and/or OpenGL.
One can select which of these to use for OpenGL use using the KIVYGLBACKEND envrionment variable by setting it to glew (the default), angle, or sdl2. Angle is currently in an experimental phase as a substitute for glew on Python 3.5 only. Gstreamer is an optional dependency which only needs to be installed if video display or audio is desired.
Ffpyplayer is an alternate dependency for audio or video. Command line Know your command line.
To execute any of the pip or wheel commands, one needs a command line tool with python on the path. The default command line on Windows is, and the quickest way to open it is to press Win+R on your keyboard, type cmd in the window that opens, and then press enter.
Alternate linux style command shells that we recommend is which offers a bash command line as as. Note, CMD can still be used even if bash is installed. Walking the path!
To add your python to the path, simply open your command line and then use the cd command to change the current directory to where python is installed, e.g. Cd C: Python27.
Alternatively if you only have one python version installed, permanently add the python directory to the path for. Python - m pip install cython docutils pygments pypiwin32 kivy. Gstreamer kivy. Glewdev kivy. Sdl2dev kivy.
Gstreamerdev. If you downloaded or cloned kivy to an alternate location and don’t want to install it to site-packages read the next section. Finally compile and install kivy with pip install filename, where filename can be a url such as for kivy master, or the full path to a local copy of a kivy. Python - m pip install - e location That allows Kivy to remain in its original location while being available to python, which is useful for tracking changes you make in Kivy for example directly with Git. To achieve using Kivy in an alternate location extra tweaking is required. Due to this wheel and pip install the dependency wheels to python Lib site-packages kivy. So they need to be moved to your actual kivy installation from site-packages.
After installing the kivy dependencies and downloading or cloning kivy to your favorite location, do the following:. Move the contents of python Lib site-packages kivy deps to your-path kivy deps where your-path is the path where your kivy is located. Remove the python Lib site-packages kivy directory altogether. From python Lib site-packages move all kivy.deps.dist-info directories to your-path right next to kivy.
Now you can safely compile kivy in its current location with one of these commands. Double-click method If you only have one Python installed, you can associate all.py files with your python, if it isn’t already, and then run it by double clicking. Or you can only do it once if you want to be able to choose each time:. Right click on the Python file (.py file extension) of the application you want to launch.
From the context menu that appears, select Open With. Browse your hard disk drive and find the file python.exe that you want to use. Select “Always open the file with” if you don’t want to repeat this procedure every time you double click a.py file. You are done.
Open the file. Send-to method You can launch a.py file with our Python using the Send-to menu:.
Browse to the python.exe file you want to use. Right click on it and copy it. Open Windows explorer (File explorer in Windows 8), and to go the address ‘shell:sendto’. You should get the special Windows directory SendTo.
Paste the previously copied python.exe file as a shortcut. Rename it to python. Python27-x64 You can now execute your application by right clicking on the.py file - “Send To” - “python ”.
