FFProbe Wasm

A Web-based FFProbe. Powered by FFmpeg, Vue and Web Assembly!

https://alfg.github.io/ffprobe-wasm/

⚠️ ️Compatible with Chrome and Edge only due to limited support for SharedArrayBuffer and the required CORS headers for Firefox on Github Pages.

Development

ffprobe-wasm uses emscripten to compile FFmpeg's libav to Web Assembly via Docker.

Emscripten is also used to create and compile the Wasm bindings to be imported by the browser.

Requirements

• nodejs - https://nodejs.org/en/download/
• docker - https://docs.docker.com/desktop/

Setup

• Clone project and build the Wasm module via Docker:

docker-compose run ffprobe-wasm make

This will build the Wasm module and place it into the /dist directory.

• Copy the JS and Wasm modules into www/public/:

cp -a dist/. www/public/

• Install and run the web application:

cd www
npm install
npm run serve

• Load http://localhost:8080/ in the web browser.

Compiles and minifies for production

npm run build

Deploy

Deploys to Github Pages
