'It's the perfect app to stream your media to your Chromecasts'

'No fiddling about with extra services, just find the file you want and have it play in the big screen.' - Gizmodo

It transformed my Chromecast from a Netflix and YouTube machine to a watch-whatever-I-want-machine. Which is great!

- Shonda, Videostream User

Let me start by saying that I recently bought the lifetime premium membership and I absolutely love Videostream. It is my favorite thing in the world after pizza and Coca-Cola.

- Aldo, Videostream Premium User

I have a very large movie collection on a networked drive, and it never fails to load the movies, cast them, load subtitles, etc. It's a piece of technology and media genius, so thank you all.

I just wanted to say how much I love Videostream. I use it almost every day. Now that I can select files right from my phone, it is a completely hassle free experience.

  • Clicking the toolbar button will open the popup, but depending on the context, it may not be possible to cast anything.

    As a last resort, casting the tab or screen may provide a means of displaying this media on the Chromecast, but it has its own limitations: the performance is very poor and there's no audio casting.

  • Why do I need the bridge?

    Access to TCP/UDP sockets.

    Network discovery for Chromecast devices relies on mDNS, the implementation of which is reliant on being able to send UDP packets. Communication with the Chromecast device itself relies on a TCP connection. The current workaround is to offload that work to a native companion application that the extension can then launch and communicate with.

    It's possible that this functionality will be re-exposed to extensions, in which case the bridge will be made redundant:

  • How do I completely remove the bridge?

    • Windows

      Removing the bridge on Windows should be as easy as running the uninstaller (C:Program Filesfx_castuninstaller.exe) found in the control panel or settings application.

      To manually uninstall, remove the following files/folders and registry keys:

      • C:Program Filesfx_cast
      • HKLMSoftwareMozillaNativeMessagingHostsfx_cast_bridge
      • HKLMSoftwareMicrosoftWindowsCurrentVersionUninstallfx_cast_bridge
    • macOS

      Remove the following files/folders:

      • /Library/Application Support/fx_cast/
      • /Library/Application Support/Mozilla/NativeMessagingHosts/fx_cast_bridge.json
    • Linux

      On Debian-based systems, remove the fx-cast-bridge package, otherwise remove the fx_cast_bridge package.

      To manually uninstall, remove the following files/folders:

      • /opt/fx_cast/
      • /usr/lib/mozilla/native-messaging-hosts/fx_cast_bridge.json OR
      • /usr/lib64/mozilla/native-messaging-hosts/fx_cast_bridge.json
  • Why is there no sound when casting a screen or tab?

    API limitations. There's no method of obtaining the audio streams. Merging of audio streams from remote media is also not possible due to cross-origin issues.

  • Why doesn't 𝑥 site work?

    Compatibility with Chrome is far from perfect. Most sites will only enable their cast support if the browser reports itself as Chrome. Ensure that you've added the site to the whitelist. Some sites may not test their Chrome-specific code with Firefox, so it's possible that they're using incompatible/non-standard APIs.

    The API is also not fully implemented and is missing some methods (mostly queue management). The current implementation likely also has edge-cases and bugs which may cause issues.

    Check the compatibility list or if it's missing, submit a new compatibility report issue.

  • Why can't I cast DRM-encumbered media?

    Unforunately, for DRM-encumbered media, there's no network-accessible URL to provide to the Chromecast and no means of accessing the media streams. The only way to cast on sites like this is via built-in Chromecast support (look for a cast button), which may not always be available.

  • Why is it taking so long for a full release?

    Though I do enjoy working on this, it's (obviously) not a full-time thing. It's just a hobby project. You can help speed up development by contributing (see below).

  • How can I support development?

    Contributing code, translations, compatibility reports, or even reporting bugs is very helpful. See the contributing guide for more information.
