There are two ways of building GStreamer on Windows - using either cerbero or gst-build. As gst-build is a lot quicker, we will use this approach in this post.
GStreamer relies on various 2D font rendering and layout libraries such as Pango and Cairo to generate text for the Pango plugin, which contains elements such as textoverlay. However, building GStreamer on Windows using gst-build does not currently include support for Pango.
In this post, we will learn how to add the Pango plugin to a gst-build installation on Windows.
If you haven't already followed my previous guide on GStreamer and Windows, please follow the steps there to build GStreamer from source.
Now, we will need to clone a few more repositories into our source directory :
Next we open a Visual Studio x64 command prompt and execute the following:
> cd freetype2 && meson build --prefix=%GSTREAMER_1_0_ROOT_X86_64% --buildtype=release && ninja -C build install > cd ..\pixman && meson build --prefix=%GSTREAMER_1_0_ROOT_X86_64% --buildtype=release && ninja -C build install > cd ..\harfbuzz && meson build --prefix=%GSTREAMER_1_0_ROOT_X86_64% --buildtype=release && ninja -C build install > cd ..\cairo && meson build --prefix=%GSTREAMER_1_0_ROOT_X86_64% --buildtype=release && ninja -C build install > cd ..\pango && meson build -Dintrospection=false --prefix=%GSTREAMER_1_0_ROOT_X86_64% --buildtype=release && ninja -C build install > cd ..\gst-build-x64 && meson build --reconfigure --prefix=%GSTREAMER_1_0_ROOT_X86_64% --buildtype=release && ninja -C build install
At this stage, it is a good idea to delete our plugin cache:
> rmdir /Q /S c:\\Users\YOUR_USER_NAME\AppData\Local\Microsoft\Windows\INetCache\gstreamer-1.0
And finally:
> gst-inspect-1.0 textoverlay
should find the overlay plugin!
