I Have an iPhone 5 with Air Video HD. I have 2 Media Center type computers (1 Mac 1 PC). I want to stream the media from those 2 computers, via my iPhone using Air Video HD to an HDTV that has a Chromecast attached USB/HDMI.
Based on prior comment above "Yes (you need to activate Early Access in Air Video HD)", I did so "activate Early Access" in the Air Video HD app on the iPhone. Then I think I realized I had to stream it to an app on the Chromecast, otherwise that output source did not show in the AirPlay list in Air Video HD on the iPhone. So I found and bought the Air Video HD app for FireTV, which should be the same as Chromecast I would think
So, now I have an app in my Chromecast app list on the HDTV, and when I play a video from either media source via Air Video HD on the iPhone, the Air Play list does include FireTV (assuming it means the same as Chromecast).
If I select that, it does start the Air Video HD app on the HDTV within Chromecast as if its going to play the stream but it never starts. And after 30 seconds, the iPhone starts playing the video local again.
