Chrome cast don't play video

[stokdesign 0]

Hi, I have Emby server on my Mac (Version 3.0.5675.1) and i want to play a video to my chromecast from Chrome (Version 44.0.2403.89 (64-bit)). I can connect Chrome with Chromecast and on my TV appears "Ready to cast" but when I try to play a video nothing happens.

 

How can I resolve?

 

Thanks
