When I watch YouTube on my Virgin Media V6 or Firefox on my Windows 10 PC, I often see the VP9 codec. But the same video on Firefox on my Amazon Fire TV stick is AVC1, and I was wondering why.

Here's an example video:

As far as I can tell neither the 1st or 2nd gen FireTV stick support VP9 hardware decoding, it's probably why it fall back to H.264 (AVC).

I worked testing STB and DTV platforms and the chips there didn't have VP9 simply because so many countries don't transmit it and that would have increased costs.

My understanding is that the the Sky Q 1TB does not support VP9, don't know if this is also true of the 2TB box.

Basically the same main chip from the same company (Broadcom) inside.
Guess where I worked for several years.
