    ​Несколько слов о тайм-лимитах для T2.

    Мне нравится, как команда WebP определяет "скоростные режимы": не "fast" и "slow", а "capture mode" и "delivery/storage mode".


    Предположим, необходим кодек для покадрового lossless-сжатия видео, захваченного с экрана во время игры. У геймера 8-ядерный проц, из которых только 2 ядра могут быть отданы под real-time сжатие. Видео 1080@60 - это 375 MB/s, то есть минимальная однопоточная производительность кодека = 200 MB/s.


    В то же время, победителем в категории "T2, Rapid" может стать асимметричный кодек с соотношением "enc / dec" == "36 s / 4 s" == "28 MB/s / 250 MB/s", который useless для описанного выше варианта применения.
