Google si to prosadí z pozice síly nehledě na to, že to prozatím žáden AV hardware nepodporuje.Dám příklad v posledních updatech na většině Android TV Youtube přestal zobrazovat 4k/60fps. Pokud je zdroj videa v tomto formátu, zobrazí jej jen v 720p. Určitě potěší každého, kdo si zrovna vybalí z krabice new oled tv s androidem...

To by som skôr videl na podporu kodekov v TV, ako na to, čo Google zakázal (práve som pozeral na mojom, 4K@60 je stále default).
Youtube podporuje AVC len do 1080p60; video s vyšším rozlíšením alebo HDR je dostupné len vo VP9 alebo AV1. Napríklad SK

Kodekama to není ty jsou podporovány. 4k 60fps ma u Youtube na android TV v prubehu let po updatech celkem pohnutou historii. Nejdriv ok, pak uplne vypnuti, pak zase ok, a ted v rezimu 720p. Pouzivám apku treti strany viz navod v odkazu, ale u te neni stabilita zadna hitparada.
