First let me say what my main goal is. My main goal is for me to be able to play .mp4 movies on my Chromecast.

I tried to play the files directly in Chrome but no sound was being produced. As a result, I was wondering if there was a way to host my videos on my own personal video site. The site will never see the light of the WWW and will only reside on my LAN. My host is a 10TB FreeNAS system.

I would prefer to view the videos in HTML 5.

Any help is appreciated!
