I-MP4V imele ividiyo ye-MPEG-4. Yadalwa yi-Moving Pictures Experts Group (MPEG) njenge-codec esetshenziselwa ukucindezela nokudidliza idatha yevidiyo.
Cishe ngeke ubone ifayela levidiyo elinesandiso sefayela seMP4V. Kodwa-ke, uma wenza, ifayela le-MP4V lingakwazi ukuvula isidlali semidiya ye-multi-format. Sinabantu abadlali be-MP4V abalwe ngezansi.
Uma ubona "i-MP4V" kumongo wefayela levidiyo, kusho ukuthi nje ividiyo ivunyelwe nge-codec ye-MP4V. I-MP4 , isibonelo, isitsha esisodwa sevidiyo esingasebenzisa i-codec ye-MP4V.
Ulwazi olungaphezulu kwi-MP4V Codec
MPEG-4 inikeza indinganiso yokuchaza indlela yokucindezela idatha yomsindo nevidiyo. Ngaphakathi kuzo izingxenye eziningana ezichaza ukuthi izinto ezithile kufanele zisebenze kanjani, enye yazo ukucindezelwa kwevidiyo, okuyingxenye 2 yesichazelo. Ungafunda kabanzi mayelana ne-MPEG-4 Ingxenye 2 ku-Wikipedia.
Uma uhlelo noma idivaysi ithi isekela i-codec ye-MP4V, kunjalo, kusho ukuthi izinhlobo ezithile zamafomethi wefayela wevidiyo zivunyelwe. Njengobe ufunde ngenhla, i-MP4 yifomethi eyodwa yesitsha esingasebenzisa i-MP4V. Noma kunjalo, kungenzeka ukuthi isebenzise i-H264, i-MJPB, i-SVQ3, njll. Ukuba nevidiyo ne-extension ye-.MP4 akusho ukuthi isebenzisa i-codec ye-MP4V.
I-MP4V-ES imele i-MPEG-4 Elemental Stream Stream. I-MP4V ihluke ku-MP4V-ES ngoba okokuqala kuyi-data yevidiyo engavamile kuyilapho i-RTP (idatha yangempela yesikhathi sokuthutha) ikulungele ukuthunyelwa ngenqubo ye-RTP yenethiwekhi. Le protocol isekela kuphela i-MP4V ne-H264 codecs.
Qaphela: I- MP4A iyi-codec yomsindo engasetshenziswa ngaphakathi kweziqukathi ze-MPEG-4 njenge-MP4. I-MP1V ne-MP2V yi-codecs yevidiyo futhi, kodwa ibizwa ngokuthi amafayela wevidiyo we-MPEG-1 namafayela wevidiyo we-MPEG-2, ngokulandelana.
Indlela Yokuvula Ifayela le-MP4V
Ezinye izinhlelo zisekela i-codec ye-MP4V, okusho ukuthi ungavula amafayela we-MP4V kulawo mahlelo. Khumbula ukuthi nakuba ifayela lingase libe ifayela le-MP4V ngomqondo wezobuchwepheshe (njengoba isebenzisa leyo codec), akudingeki ukuba nesandiso se-.MP4V .
Ezinye izinhlelo ezingavula amafayela we-MP4V zifaka i-VLC, i-Windows Media Player, iMicrosoft Windows Video, i-QuickTime, i-iTunes, i-MPC-HC, futhi cishe amanye amavidlali abezindaba abehlukene.
Qaphela: Kunezinhlobo eziningi zefayela ezabelana ngezinhlamvu ezifanayo ku-MP4V, njenge- M4A , M4B , M4P , M4R , ne-M4U (i-MPEG-4 Uhlu lwadlalwayo). Amanye alawa mafayela angase angavuli ngendlela efanayo namafayela we-MP4V ngoba ngamunye usetshenziselwa injongo ehlukile.
Indlela yokuguqula ifayela le-MP4V
Esikhundleni sokufuna i-MP4V kuya ku-MP4 converter (noma noma iyiphi ifomethi ofuna ukuyilondoloza kuvidiyo), kufanele uthole i-converter yevidiyo ngokusekelwe kwesandiso sefayela esetshenziswayo.
Isibonelo, uma unefayela le-3GP elisebenzisa i-codec ye-MP4V, vele ubuke i-converter video ye-3GP.
Qaphela: Khumbula ukuthi amafayela we-M4V awafani ne-codec ye-MP4V. Loluhlu lwabaguquleli bevidiyo yamahhala lungasetshenziswa futhi ukuthola i-M4V kuya ku- MP3 converter, eyodwa egcina iM4V kuya ku-MP4, njll.
MP4 vs M4V vs MP4V
Izandiso zefayela le-MP4, i-M4V, ne-MP4V zifana kakhulu kangangokuthi ungaziphutha kalula ngefomethi efanayo yefayili.
Nakhu ukuthi ungaqonda kanjani ngokushesha umehluko wabo oyisisekelo:
- I-MP4: I-codec nefomethi yokuqukatha ukugcina umsindo nevidiyo efayeleni elilodwa nje
- I-M4V: Ifayela le-MP4 elingavunyelwa ikhophi ye-DRM
- I-MP4V: I-MPEG-4 Emifudlana yevidiyo engeke igcinwe ku-container ye-MP4
Chofoza kunoma yikuphi ukuxhumanisa ngenhla ukuthola ulwazi oluthe xaxa kumafomethi nakuhlu lwezinhlelo ezingavulwa futhi ziguqule amafayela we-MP4 ne-M4V.
