+# Cross compiling GStreamer with gst-build
+
+GStreamer can be cross compiled for various platforms using gst-build. However,
+only dependencies that are ported to the Meson build system will be built. It is
+recommended to use Cerbero to cross compile GStreamer when other external
+dependencies are required.
+
+Once the toolchain is installed and a Meson cross file is created, to build
+GStreamer simply run for example: `meson --cross-file data/cross-files/mingw_w64_x86-64.txt builddir`.
+
+## Android
+
+Requires Android API level >= 28, previous versions are missing *iconv* dependency.
+
+- Download and extract the [NDK](https://developer.android.com/ndk/)
+- Create a Meson cross file, you can use `android_arm64_api28.txt` as example
+  and change CPU architectures and toolchain path using the prebuilt toolchains
+  from the NDK.
+
+Notes:
+- On fedora the Android NDK requires the `ncurses-compat-libs` package.
+
+## Windows
+
+GStreamer can be cross compiled for Windows using mingw packaged in most
+distribution.
+
+The Meson cross file `mingw_w64_x86-64.txt` can be used when targeting amd64
+architecture, or adapted for i686 arch.
+
+### Fedora
+
+- Install the toolchain packages: `mingw64-gcc`, `mingw64-gcc-c++`. Fedora
+  provides many other optional dependencies that could be installed as well.
+  For example: `mingw64-gettext`, `mingw64-libffi`, `mingw64-zlib`.
+
+### Ubuntu
+
+- Install the toolchain package: `gcc-mingw-w64`.
