-## Building (Old Instructions)
-
-You need:
-
-* Qt 5.9.5
-* cmake 3.1 or newer
-* ninja is recommended for building
-* FFmpeg 3.x and mpv from github
-
-## Building on Mac OS X
-
-Configure
-
-If you're happy just building from the command line then run CMake for the ninja build tool:
-
-* Install ninja with homebrew:
-  * ``brew install ninja``
-* Install mpv and other dependencies with homebrew:
-  * ``brew install mpv --with-shared --HEAD``
-* ``mkdir build ; cd build``
-* ``cmake -GNinja -DCMAKE_BUILD_TYPE=Debug -DCMAKE_INSTALL_PREFIX=output ..``
-
-Build (ninja):
-
-* ``ninja``
-
-Make a distributable package:
-
-* ``ninja install`` (be patient, it's slow)
-
-Or if you prefer working in Xcode, run CMake for the xcode build):
-
-* ``mkdir build ; cd build``
-* ``cmake -GXcode ..``
-
-## Building on Linux

-Jellyfin Media Player officially requires Qt 5.9.5. Our users have indicated that Qt 5.10 and Qt 5.11 also builds correctly. However, Qt 5.11.0 and 5.11.1 versions are _incompatible_ and should be avoided. Qt 5.12 may work for you. Please consider building PMP within a dedicated VM or Docker container if your system has a Qt version installed newer than 5.9.5. Downgrading a system Qt will cause issues in other applications depending on a newer Qt version.
-
-These instructions are for Ubuntu 16.04 LTS and up. They were tested on a fresh install without extra options and with auto-updates applied.
-
-First, some preparations:
-
-* ``sudo apt install autoconf automake libtool libharfbuzz-dev libfreetype6-dev libfontconfig1-dev
-    libx11-dev libxrandr-dev libvdpau-dev libva-dev mesa-common-dev libegl1-mesa-dev
-    yasm libasound2-dev libpulse-dev libuchardet-dev zlib1g-dev libfribidi-dev git
-    libgnutls28-dev libgl1-mesa-dev libsdl2-dev cmake``
-* ``mkdir jmp``
-* ``cd jmp``
-
-Systems not based on Debian/Ubuntu will have similar packages, but you'll need to figure out their names yourself.
-
-### Downloading and installing Qt
-
-If your distro provides a Qt 5.9.5 package, try to use it. Otherwise, download a supported Qt version from qt.io.
-
-### Building mpv and ffmpeg
-
-While most distros have FFmpeg and mpv packages, they're often outdated. It's recommended to build a current version, or to get them from 3rd party sources (some are listed on https://mpv.io/installation/).
-
-Here are instructions how to build them locally. First you need to install some build prerequisites:
-
-* ``git clone https://github.com/mpv-player/mpv-build.git``
-* ``cd mpv-build``
-* ``echo --enable-libmpv-shared > mpv_options``
-* you can also add ``echo --disable-cplayer >> mpv_options`` to prevent mpv CLI from being built
-* ``./rebuild -j4`` (this steps checks out all sources and compiles them and takes a while)
-* ``sudo ./install``
-* ``sudo ldconfig``
-
-With this, libmpv should have been installed to ``/usr/local/``. It does not conflict with the system. In particular, it does not install or use FFmpeg libraries. (The FFmpeg libraries are statically linked in libmpv when using mpv-build.)
-
-You can also attempt to skip the installation step, and change the paths in the PMP build step to the build directory, but this is more complicated.
-
-### Building jellyfin-media-player
-
-Assuming that everything else has installed correctly, building Jellyfin Media Player should now be fairly straightforward:
-
-* ``cd ~/jmp/``
-* ``git clone git://github.com/iwalton3/jellyfin-media-player``
-* ``cd jellyfin-media-player``
-* ``mkdir build``
-* ``cd build``
-* ``cmake -DCMAKE_BUILD_TYPE=Debug -DQTROOT=/opt/Qt5.9.5/5.9/gcc_64/ -DCMAKE_INSTALL_PREFIX=/usr/local/ ..``
-* ``make -j4``
-* ``wget https://github.com/iwalton3/jellyfin-web-jmp/releases/download/jwc-10.7.2-2/dist.zip``
-* ``unzip dist.zip``
-* ``sudo make install``
-
-You should now be able to start PMP as ``jellyfinmediaplayer`` from the terminal.
-
-If you use your distro's Qt, use `-DQTROOT=/usr` or similar.
-
-Normally, the Ninja generator (via ``-GNinja``) is preferred, but cmake + ninja support appears to be broken on Ubuntu 16.04.
-
-If you want, you can wipe the ``~/jmp/`` directory, as the PMP installation does not depend on it. Only Qt and libmpv are needed.
-
-Sometimes, PMP's cmake run mysteriously fails. It's possible that https://bugreports.qt.io/browse/QTBUG-54666 is causing this. Try the following:
-
-* locate ``Qt5CoreConfigExtras.cmake`` of your Qt build/installation
-* comment ``set_property(TARGET Qt5::Core PROPERTY INTERFACE_COMPILE_FEATURES cxx_decltype)`` with ``#``
-
-Sometimes, PMP will pick up SDL 1.x libraries. This is not supported and will lead to build failures. You need SDL 2. You can disable use of SLD with ``-DENABLE_SDL2=off`` (it's used for some remotes).
