Supported platforms

Linux
macOS
Windows (TODO)

Only tested on Linux and macOS. mDNS library issue to be fixed. mdns only works on Windows, mdns-js only works on Linux.

Building

Requirements

NodeJS
node binary in path
~~Bonjour SDK (Windows)~~

Instructions

git clone https://github.com/hensm/fx_cast.git
npm install
npm run build
npm run install-manifest

This will build the ext and app, outputting to dist/.

dist/app/ contains the bridge binary and manifest with the path pointing that binary. install-manifest copies the manifest to the proper location (or adds its current location to the registry).

dist/ext/ contains the built extension in the format fx_cast-<version>.zip in addition to the unpacked extension at dist/ext/unpacked/.

Watching ext changes and auto reload:

npm run watch --prefix ./ext

# In seperate terminal
npm run start --prefix ./ext

Packaging

Packaging currently only possible on macOS:

npm run package

dist/app/ contains the installer package: fx_cast_bridge.pkg (macOS). dist/ext/ contains the built extension.

Testing

Testing requires geckodriver (or chromedriver for Chrome parity testing). See selenium-webdriver installation instructions (ignore npm install).

Chrome doesn't load the media router in a temporary selenium profile, so there's a bundled profile (test/ChromeProfile.zip). Extract the folder within as test/ChromeProfile/.

npm run build
npm test
SELENIUM_BROWSER=chrome npm test

Usage

Extension can be loaded from about:debugging as a temporary extension.

Most sites won't load the cast API unless the browser presents itself as Chrome. The extension includes a method of spoofing the user agent string, sites can be whitelisted via the options page. Whitelist entries are specified as match patterns. To whitelist all sites, add <all_urls> to the whitelist, though this could cause breakage on random sites.

HTML5 media elements have a "Cast..." context menu item that triggers a sender application. Only works on remote (non-local) media that isn't DRM-encumbered.

Cast-enabled websites will load the sender API shim and display a cast button as in Chrome, provided there are no bugs/incompatibilities with the shim.
