How do I stream content from my PC to the Chromecast?
The best option for enabling media to be streamed from your PC to the Chromecast is by using an app called Plex.
In order for Plex to find the media on your PC, you’ll need to install a small client that will run in the background and index all your pictures, movies, and music. You then install the companion app on your Android device and Plex will automatically detect the client running on your PC and also discover all the indexed media.
Since Plex has just been updated to include Chromecast support, it is then a simple case of selecting the media you want to stream through Plex and selecting your Chromecast to stream to.
