They encode videos ahead of time and they likely decided that whatever hardware you’re judging them by is only .9% of the market so fuck those guys.
Big companies use percentages in places they shouldn’t and it gets them in trouble. .1% when you have a billion users is a million people you’re shitting on.
For me that might be a dozen people. Very different.
Supposedly, the whole point of Google financing “open codecs” was for them to break free from MPEG codec licensing. I imagine the total amount of fees had a lot of zeros. So, yes, each time they don't serve H.264 (unless absolutely required) results in saving a lot of money.
