Installing castnow

Wanted to stream videos from the Raspberry Pi to my Chromecast and control it on the command line through ssh.  Found out about a cli tool that does just that.  It’s called castnow and it was quite a beast figuring out how to install it, so I’ve boiled it down here.

# It’s actually not a regular program you can just download with apt-get.  It runs on nodejs.

So here’s the install breakdown:

Pre-install flight check:

sudo apt-get update -y

sudo apt-get install wget

# Update and install wget if not already installed.


Install nodejs:


tar -zxvf node-v0.10.28-linux-arm-pi.tar.gz && cd node-v0.10.28-linux-arm-pi/bin

This downloads an archive of nodejs version 0.10.28 and extracts it.

sudo su


apt-get install npm

npm install -g castnow

Change to root and add this path so that castnow will be able to run as a regular command once it’s installed.  Install npm, the nodejs package manager.  Then use npm to install castnow.

su pi

sudo ln -s “$(which nodejs)” /usr/bin/node

Change back to the pi user and make a symbolic link to the node directory in /usr/bin.

There’s a few cool things you can do with castnow.

  • Play local .mp4 video files.

castnow ./video.mp4

  • Play video and / or audio files from a directory.

castnow ./Media/

  • Play multiple videos in a row.

There’s many more commands and options to play with, more information can be found on castnow’s github:
