Ingabe ingomsindo, ividiyo, noma kokubili?
Le FAQ yedijithali yedijithali ichaza ngokufishane izinto ezisisekelo zefomethi ye-MP4.
Incazelo
Ngisho noma ifomethi ye-MP4 ivame ukucatshangwa njenge-algorithm ye-encoding yevidiyo, empeleni isakhiwo sesitsha esingabamba noma yiluphi uhlobo lwedatha. Kanye nokukwazi ukuphatha noma iyiphi inamba yevidiyo noma ukusakazwa komsindo, ifayela le-MP4 lingagcina ezinye izinhlobo zemidiya njengezithombe ngisho nemibhalo engezansi. Ukudideka ukuthi ifomethi ye-MP4 i-video-kuphela ivela kumadivayisi afanelekayo evidiyo ebizwa ngokuthi abadlali be-MP4.
Umlando
Ngokusekelwe kwefomathi ye-AppleTextTime (.mov), ifomethi ye-MP4 yenkomo yaba ngowokuqala ngo-2001 njenge-ISO / IEC 14496-1: 2001. Manje ku-version 2 (MPEG-4 Ingxenye 14), izinga le-ISO / IEC 14496-14: 2003 lakhishwa ngo-2003.
Izandiso Zefayela Ezidumile
Njengoba kukhonjisiwe ngaphambilini, isitsha se-MP4 singabamba izinhlobo ezahlukene zemifudlana yedatha futhi ingabelwa yizandiso zefayela ezilandelayo:
