I-Mpeg4 ne-Mp4 yinto efanayo? Thola ama-nuances

Kuze kube manje, akunakwenzeka ukucabanga ngomsebenzisi oyedwa we-Global Network, ongayikuhlangana cishe nsuku zonke ngokuqukethwe kwe-multimedia. Okukhangayo kunazo zonke kusukela ekubukeni kokuqwashisa nokusebenza phakathi kolwazi olunjalo yividiyo. Ithelevishini isivele ifika ngaphambili futhi, isebenze noma ijabulisa, umsebenzisi ukwandisa kakhulu amafayela evidyo avela ku-Inthanethi, amafomethi ahlukahlukene namuhla akhona nenani elikhulu.

Ngokuvamile, ukulanda amavidiyo noma ama-movie avela ku-Intanethi, umsebenzisi kufanele abhekane nezinhlobo ezinjalo zamafayela njenge-Mpeg4 ne-Mp4 - lokhu kuyinto efanayo, abaningi bakholwa. Sizoyiqonda, akunjalo ngempela.

Umehluko omkhulu

Eqinisweni, umehluko phakathi kwe-MP4 ne-MPEG4 yinto ephawulekayo. Umehluko omkhulu yiqiniso lokuthi i-MPEG4 yindlela yokunciphisa idatha ye-audio nevidiyo. Futhi i-MP4 iyifomethi yesitolo sedatha. Okusho ukuthi, i-MP4 yenzelwe futhi isetshenziswe njengesitsha lapho idatha ye-audio ne / noma yevidiyo igcinwa khona. Ngakho-ke, isitatimende sokuthi iMpeg4 neMp4 sinye into ayilungile. Sizoqonda injongo yesakhiwo ngasinye.

I-MPEG-4

Inhloso eyinhloko ye-MPEG-4 ukusebenzisa le ndlela yokucindezela emoyeni, ezindaweni ezisebenzisanayo nezemibala. Ukusetshenziswa kwezinga kwenza kube lula ukusebenzisa okuqukethwe komsindo kanye / noma ividiyo hhayi ngezikhathi ezithile kuphela. Ngaphezu kwalokho, izinga likhuthaza kakhulu ukuhlanganiswa kokuqukethwe okwakhiwa kweziteshi ezimbili (i-audio nevidiyo) endaweni eyodwa kanye ne-multimedia efanayo. Konke lokhu kwaholela ekusakazeni kabanzi kwe-codec ezindaweni ezithelevishini nakwebhu.

MP4

Akunakusho ukuthi i-Mpeg4 ne-Mp4 yinye futhi iyafana ngesinye isizathu. I-MPEG-4 ne-MP4 yimigomo emibili edideka kalula komunye nomunye, hhayi kuphela ngoba amagama abo ahluke kuphela ezincwadini ezimbili, kodwa futhi ngoba ahlangene kakhulu emhlabeni wezinombolo eziningi zamafayela abezindaba. Ifomethi ye-MPEG4 ne-MP4 njengesiqukathi sokugcina idatha, isakazeka kakhulu okungenani ngenxa yesilinganiso esamukelekayo sekhwalithi yevidiyo nobukhulu bamakhophi aphethwe aqukethe idatha.

Ngokuqondene nalesi sici se-MP4, singasho ukuthi isilinganiso esihle kakhulu phakathi kwezinye izixazululo phakathi kwekhwalithi yevidiyo nobukhulu bayo kuye kwaholela ekubeni i-MP4 ibe yinye yamafomethi wefayili evamile kakhulu ekugcineni nasekudluliseni i-multimedia. I-MP4 ayisebenzisi kuphela kuma-computer. Kuye kwazuza ukuthandwa okukhulu kumapulatifomu amaningana eselula, ama-smartphone, amakhompyutha amathebulethi, kufaka phakathi "amafoni smart" kanye "amaphilisi" avela ku-Apple.

Kuzo zonke izixazululo ze-hardware ezibalulwe ngenhla ezikuvumela ukuba uthole, ukugcina nokudlulisa okuqukethwe kwe-multimedia, i-MP4 isetshenziswe njengefomethi yefayela ezenzakalelayo. Abasebenzisi abakhetha ukufunda ngokuqondile nangenkingeni, kanye nokurekhoda amafayela evidiyo, bazokhetha i-MP4, nakuba bangakwazi ngisho nokwahlukana komqukathi kusuka ku-MPEG-4 futhi bacabanga ukuthi i-Mpeg4 ne-Mp4 zifana. Singasho ngokuphepha ukuthi njengefomethi yevidiyo evamile, i-MP4 isetshenziswa cishe yonke indawo, futhi i-MPEG-4 iyisisombululo esicacile.
