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
2 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.shYou also need to have Binaryen and wabt available on your system.
In the project root of mediainfo.js run the following to build.
