Today, new engineers learn AV1 first. But the old ones know: beneath every AV1 stream, if you dig deep enough, you find the skeleton of libvpx—the memory pools, the loop filters, the entropy coders. She is the mother of the entire open-codec family.

But there was a cost. VP9 encoding was slow. It required sacrifice. Engineers would leave their machines running overnight, like monks illuminating manuscripts by candlelight. Mother Mary did not promise speed. She promised fidelity . She became the protector of the public internet
