However, there are some inconsistencies ... certain files give the 'ambilight' effect when played back but others not, just a steady backlight (green on my Shield, white on my FireTV 4k stick).

I'd heard that the codecs might be to blame - some not supporting the ability to extract colour/luminance data - but it seems to happen even on files that use the same coding (albeit at different resolutions).

eg. Taking two files, this one works to give the 'Ambilight' effect:

Format : Matroska
Format version : Version 4 / Version 2
File size : 319 MiB

Overall bit rate : 1 062 kb/s

... but this one doesn't:

Format : Matroska

File size : 334 MiB

... only real difference is the resolution.

Any ideas why one works and one doesn't?

A bit annoying if so, as I've started to encode all files for storage on my media NAS as 960x540.


Edit: The Ambilight effect is stunning by the way - great work on that.
