Node.js Express FFMPEG Project to Embed LIVE Streaming Video Feeds in Browser Using ffmpeg-streamer Library in Javascript



ffmpeg-streamer is a packaged nodejs express server that wraps ffmpeg to allow easy streaming of video feeds directly to modern browsers for testing purposes. It currently includes 6 different types of output streaming which are mjpegjpeg via socket.ioprogressive mp4native hlshls.js, and mse via Video input types supported are rtspmp4mjpeg, and hls.


ffmpeg-streamer has been packaged into an executable using pkg. The current binaries can be found on the releases page.

  • For desktop installation, simply download and extract.

  • For desktop usage, double click the executable to run it.
  • For command line usage, the following shows 2 options.

Or start the app from the command line via pm2



After launching, you can use it via the web interface on port 8181. For example, if your are running it on your current machine, visit it in a modern browser via http://localhost:8181. If port 8181 was already in use, it will keep incrementing the port number by 1 until it finds one available. You can launch multiple copies of the app up to a total of 10, each listening on its own port. If you would like to store your last used settings, go to http://localhost:8181/activity and click the “create” button to use the activity log.


Ffmpeg is the only external software required to run the app. Nodejs is packaged inside the binary and is not needed to be installed separately on your system. When launching the app, it tries to find ffmpeg on your system using ffbinaries. If it cannot find ffmpeg, you will be prompted to install it to the current running directory via the web interface on port 8181. If it does find ffmpeg, but you would like to install a newer version, you can visit http://localhost:8181/install and force the installation.
