10x Supermicro SSG-6049P-E1CR60H servers (60 x 3,5" HDD in 4U enclosure) - $5k each
600x WESTERN DIGITAL Ultrastar DC HC550 18TB (10800PB in total) - $500 each
~$350k in hardware, up to 20kW energy consumption, should fit in two rack towers. You can host it for about $1.5k somewhere. All assuming no redundancy :)
Some of these are probably fingerprinting but the Twitch one isn't (I worked on the video system at Twitch for a number of years).
"player-core-variant-....js" is the Javascript video player and it uses WebGL as a way to guess what video format the browser can handle. A lot of the times mobile android devices will say "I can play video X, Y, Z" but when sent a bitstream of Y it fails to decode it. WebGL allows you to get a good indication of the supported hardware features which you can use to guess what the actual underlying hardware decoder is.
This is sadly the state of a lot of "lower end" mobile SoCs. They will pretend to do anything but in reality it just... doesn't.
