Yeah, just because some data hoarder on the internet has TBs of videos doesn't mean that's normal. So weird call out.
It is however a call out of the GP as well for not knowing how ubiquitous something can be while not being shoved in your face that it is being used. The GP is evidently unaware that most streaming services will offer an h.265 encode for those users that can use it as the bandwidth savings make it very worthwhile. Mobile devices are using HEVC by default now as well as at least iOS using a still image variant. From reading elsewhere in these comments, clearly MS Teams uses it as well.
So just because you don't know it is being used does not mean it is not being used the way you might think.
Youtube detects your capabilities and sets it automatically. Unless you're using an obsolete potato network or watching low resolution stuff you'll likely get x265.
Netflix is similar. It defaults to h265 for Netflix content (because they want it to look good). Partner/licensed content uses the inferior codecs that use more bandwidth to achieve worse quality.
youtube has never and will never come to support x265 they even tried to block support from chrome becuase they hate it that much
they support x264,vp8/vp9, av1 and soon av2
they literally started and entire organisation to take on mpeg called aomedia
Pretty much everything modern except Apple. Intel since 11th gen (2021), AMD since Zen4 (2022), Samsung phones since 2021, Google phones since 2021, Mediatek since 2020.
With modern lifecycles the way they are, that's probably ~60-80% of everything out there.
lets all calm down, its about h.265 nobody sane uses anyway
