It doesn't matter whether the i686 or the x86_64 version is used. Both can
build 32-bit and 64-bit binaries when running on a 64-bit version of Windows.
2. Add ``C:\msys64\mingw64\bin`` to your ``%PATH%``. mpv will depend on several
DLLs in this folder.
2. Start a MinGW-w64 shell (``mingw64_shell.bat``). Note that this is different
from the MSYS2 shell that is started from the final installation dialog.
3. Start a MinGW-w64 shell (``mingw64_shell.bat``). For a 32-bit build, use
``mingw32_shell.bat``.
For a 32-bit build, use ``mingw32_shell.bat``.
Updating MSYS2
--------------
To prevent errors during post-install, ``msys2-runtime`` and ``pacman`` must be
updated first.
To prevent errors during post-install, the MSYS2 core runtime must be updated
separately.
```bash
# Check for updates to msys2-runtime and pacman. If there were updates, restart
# MSYS2 before continuing.
pacman -Sy --needed msys2-runtime pacman
# Check for core updates. If instructed, close the shell window and reopen it
# before continuing.
update-core
# Update everything else
pacman -Su

Running mpv
-----------
If you want to run mpv from the MinGW-w64 shell, you will find the experience
much more pleasant if you use the ``winpty`` utility
```bash
pacman -S winpty
winpty mpv.com ToS-4k-1920.mov
```
If you want to move / copy ``mpv.exe`` and ``mpv.com`` to somewhere other than
``/mingw64/bin/`` for use outside the MinGW-w64 shell, they will still depend on
DLLs in that folder. The simplest solution is to add ``C:\msys64\mingw64\bin``
to the windows system ``%PATH%``. Beware though that this can cause problems or
confusion in Cygwin if that is also installed on the machine.
Use of the ANGLE OpenGL backend requires a copy of ``d3dcompiler_43.dll`` (yes,
exactly 43) in the path or in the same folder as mpv. It must be of the same
architecture (x86_64 / i686) as the mpv you compiled. You can find a copy in the
official mpv builds:
