./configure --enable-static
make -j `nproc`
  • Build MediaInfoLib.
cd MediaInfoLib/Project/GNU/Library
./autogen.sh
./configure --enable-static
make -j `nproc`

Build MediaInfoLib for MacOS

  • Install XCode.
  • Install autoconf automake libtool pkg-config zlib wxwidgets.
brew install autoconf automake libtool pkg-config zlib wxwidgets
  • Download zlib.
curl -o zlib.tar.gz https://www.zlib.net/zlib-1.3.2.tar.gz

Build MediaInfoLib for Windows

  • Download zlib.
curl -o zlib.zip https://zlib.net/zlib132.zip
7z x zlib.zip
move zlib-1.3.2 zlib
del zlib.zip
  • Build zlib.
cd zlib
cmake -G "Visual Studio 18 2026" -A x64 -S . -B contrib/vstudio/vc18
cmake --build contrib/vstudio/vc18 --config Release
  • Patch MediaInfoLib to work with cmake-built zlib.
cd scripts/ts
deno task patch
  • Build MediaInfoLib in Visual Studio 2026.
cd MediaInfoLib\Project\MSVC2026
msbuild MediaInfoLib.slnx -t:rebuild -verbosity:diag -property:Configuration=Release -property:Platform=x64

Generate bindings.rs on Windows

This step is optional because the generated bindings.rs is broken. bindings.rs is for reference only.

  • Install bindgen-cli.
cargo install bindgen-cli
  • Generate bindings.rs.
cd BetterMediaInfo
set LIBCLANG_PATH=C:\Program Files\Microsoft Visual Studio\18\Enterprise\VC\Tools\Llvm\x64\bin\libclang.dll
bindgen ^
  --allowlist-item "MediaInfo\w+" ^
  -o src-tauri\src\bindings.rs ^
  ..\MediaInfoLib\Source\MediaInfoDLL\MediaInfoDLL.h
  • Add the following code to the top of bindings.rs to mute the warnings.
#![allow(non_camel_case_types, non_upper_case_globals, nonstandard_style, dead_code, unused_imports)]

Logging

Turn on Debug Log on Windows

set RUST_LOG=debug

Build Tauri

pnpm install
pnpm tauri dev
pnpm tauri build

Build Installers

Build NSIS Installer

  • Run the commands as follows.
node BetterMediaInfo\src-tauri\scripts\copy_dlls.cjs
node BetterMediaInfo\src-tauri\scripts\patch_tauri_conf.cjs

Config File Location

The config file BetterMediaInfo.json is resolved at runtime based on the platform and how the app is launched:

  • Linux: $XDG_CONFIG_HOME/BetterMediaInfo/BetterMediaInfo.json if XDG_CONFIG_HOME is set; otherwise $HOME/.config/BetterMediaInfo/BetterMediaInfo.json.
  • macOS: $HOME/Library/Application Support/BetterMediaInfo/BetterMediaInfo.json.
  • Windows:
    • If the executable lives under %LOCALAPPDATA%, %ProgramFiles%, or %ProgramFiles(x86)% (i.e. the app is installed), the config is stored in %APPDATA%\BetterMediaInfo\BetterMediaInfo.json.
    • Otherwise (development mode), the config is stored next to the executable (current behavior).

The config directory is created automatically on first launch if it doesn't exist.
