Kutheni u AV1 udlala ngokuchaseneyo okanye uqhuba ngokushushu kumamatshini adala?

Kuba ikhowudi iguqulwa kwinkqubo yekhompyutha. Izixhobo zokufaka ikhowudi zevidiyo ziquka kuphela uluhlu oluqinileyo lweefomati, kwaye AV1 ingaphandle kwayo kwizixhobo ezininzi, ngoko ke iframe nganye ibuyiselwa kwakhona yi-CPU endaweni yayo. Kwidesktop yangoku elahlekile; kwifowuni, ilaptop edala okanye i-smart TV ibonisa njengee-frames ezilahlekileyo, intshukumo ye-fan kunye nokutshaya kwebhetri. Ukuguqula kwifomati exhaswe yi-hardware isusa ingxaki ngokupheleleyo.
