This is a JavaScript port of the excellent MediaInfoLib and can run directly in a browser or in Node.js. It is transpiled from C++ source code using Emscripten.
Try mediainfo.js in your browser: https://mediainfo.js.org
import MediaInfoFactory from 'mediainfo.js'
MediaInfoFactory().then((mediainfo) => {
mediainfo.analyzeFile(...)
})See the API docs for detailed instructions.
You can either use a CDN to include the script file directly in your page or use a JavaScript bundler like webpack.
- CDN:
<script type="text/javascript" src="https://unpkg.com/mediainfo.js"></script> - Bundler:
npm install mediainfo.js
Be aware that mediainfo.js needs to load the MediaInfoModule.wasm file (around
3.5 MiB). The WASM module is loaded and instantiated automatically. By
default its load path is determined from the script location. This works
out-of-the-box for the UMD and Node.js version.
❗️ If using a bundler, you need to ensure the module loader can fetch the WASM file by configuring your bundler/web server accordingly (examples).
Note that you can override the WASM file location by specifying a custom
locateFile
function to MediaInfoFactory.
Install mediainfo.js from NPM.
$ npm install -g mediainfo.jsIt can be used as a CLI from the shell.
$ mediainfo.js /path/to/media.aviOr use it as a library.
Install Emscripten preferably using Emscripten SDK.
$ git clone https://github.com/emscripten-core/emsdk.git
$ cd emsdk
$ ./emsdk install latest
$ ./emsdk activate latest
$ source ./emsdk_env.shIn the project root of mediainfo.js run the following to build.
$ pnpm install
$ pnpm buildFind the resulting files in the dist directory.
