Leapcast is a software implementation of the Chromecast. It works on the same protocol that Chromecast does and can be easily used as a Chromecast device. What is interesting is that the cost of a Chromecast device and a Raspberry Pi is the same($35).
To use your Raspberry Pi as a Chromecast device follow the following steps:
1. Upgrade your Raspberry Pi
sudo apt-get update sudo apt-get upgrade
2. Install Chromium browser
sudo apt-get install chromium
3. Now we will install dependencies for leapcast and clone the git repository
git clone https://github.com/dz0ny/leapcast.git
cd ./leapcast
sudo apt-get install virtualenvwrapper python-pip python-twisted-web python2.7-dev
Now reset your ssh connection by typing exit and then again ssh into your Pi.
4.Now you are ready to run leapcast. Make sure your HDMI cable is connected.After that type
cd leapcast/
startx &
mkvirtualenv leapcast
pip install .
DISPLAY=:0 leapcast --chrome /usr/bin/chromium
If you get the error “failed to load nss libraries” then type
sudo ln -s /usr/lib/arm-linux-gnueabihf/nss/ /usr/lib/nss
With this i could stream youtube videos to my Pi but I have not tried the new screen cast feature yet. If you try it and it works please leave a comment.
