Un file video a 360 gradi sembra essere un tipo speciale di file MP4.
Ho usato un'estensione del browser per scaricare il video di YouTube che hai citato.
Se visualizzato in "VLC media player" viene mostrato l'intero panorama a 360 gradi, anziché una vista specifica.
( EDIT: Al 30 novembre 2016, VLC Player ora riproduce video a 360º .)
L'articolo "Carica video a 360 gradi - Guida di YouTube" ( link ) descrive come caricare video a 360 gradi ed elenca alcuni riferimenti software, incluso Kolor. Il Kolor Occhi Player Free Video per Windows, Mac, Android, iOS e giocheranno video sferiche sia online che offline.
L'utility Linux file
elenca il video come:
ISO Media, MP4 v2 [ISO 14496-14]
