I have been surprised it has not been more heavily promoted by +Google. It was only recently listed on the Chromecast page.
Avia is usually dismissed in favor of Plex which I have never gotten to work and whose pricing scheme is $3.99 a month. You can get Chromecast support with Avia for $2.99.
So what does Avia allow me to do?
- I have an simple way to cast the photos and videos on my device to my TV. This is great for sharing a photo or video I just took with family via a large screen TV.
- Avia connects directly to Google Photos which gives me access all my instantly uploaded content. I simply load an album, click play, and Chromecast it.
- If I download movies to my device I can cast them via the Avia app. This works great for 720p and below with buffering issues at higher bit rates.
