I-MP4V imele i-MPEG-4 Video. Yadalwa ngokuhambisa iqela lezakhono zeMifanekiso (MPEG) njenge-codec esetyenziselwa ukucwangcisa nokudibanisa idatha yevidiyo.
Mhlawumbi awuyi kubona ifayile yevidiyo eneenombolo zefayile ze .MP4V. Nangona kunjalo, ukuba wenzayo, ifayile ye-MP4V isakwazi ukuvula kumdlali wesigidimi semidiya. Sinabo abadlali be-MP4V abalwe apha ngezantsi.
Ukuba ubona "MP4V" kumxholo wefayili yevidiyo, ithetha nje ukuba le vidiyo icinezelwe nge-codec ye-MP4V. I-MP4 , umzekelo, isitsha esinye sevidiyo esingasebenzisa i-codec ye-MP4V.
Ulwazi olungakumbi kwi-MP4V Codec
I-MPEG-4 inikeza umgangatho wokuchaza indlela yokunyanzelisa idatha yomsindo kunye nevidiyo. Ngaphakathi kukho iinxalenye ezininzi ezichaza indlela izinto ezithile ezifunekayo ukusebenza ngayo, enye yazo i-compression compression, esekuqaleni kweCandelo 2 leenkcukacha. Unokufunda ngakumbi malunga ne-MPEG-4 Ingxenye 2 kwi-Wikipedia.
Ukuba inkqubo okanye idivaysi ithi isekela i-codec ye-MP4V, ngokuqinisekileyo, kuthetha ukuba iintlobo ezithile zeefomati zefayile zevidiyo zivunyelwe. Njengoko ufunde ngentla, i-MP4 enye ifomathi yendlela yokusebenzisa i-MP4V. Nangona kunjalo, kunokuthi isebenzise iH264, i-MJPB, i-SVQ3, njl. Ukuba nevidiyo kunye nokwandiswa kweMP4 akuthethi ukuba usebenzisa i-codec ye-MP4V.
I-MP4V-ES imele i-MPEG-4 ye-Elemental Stream. I-MP4V ihluke kwi-MP4V-ES kwinto yangaphambili i-data yeqhosha yevidiyo ngeli xesha i-RTP (i-real-time transport protocol) idatha ekulungele ukuthunyelwa kwi-network protocol ye-RTP. Le protocol isekela kuphela i-MP4V ne-H264 codec.
Qaphela: I- MP4A yi-codec ye- audio engasetyenziswa ngaphakathi kwe-MPEG-4 izitsha ezifana ne-MP4. I-MP1V kunye ne-MP2V zikhowudi zevidiyo, kodwa zibizwa ngokuba yi-MPEG-1 iifayile zevidiyo kunye neefayile zevidiyo ze-MPEG-2, ngokulandelanayo.
Indlela yokuvula ifayile ye-MP4V
Ezinye iiprogram zixhasa i-MP4V codec, oku kuthetha ukuba unokuvula iifayile ze-MP4V kulezo nkqubo. Khumbula ukuba nangona ifayile ingaba yifayile ye-MP4V kwingqiqo yobugcisa (ekubeni isebenzisa loo codec), akudingeki ukuba yongezwe i .MP4V .
Ezinye iinkqubo ezinokuvula iifayile ze-MP4V ziquka i-VLC, i-Windows Media Player, iMicrosoft Windows Video, i-QuickTime, i-iTunes, i-MPC-HC, kunye nabanye abadlali beendaba.
Qaphela: Kukho iintlobo ezininzi zeefayile ezenza iifayile ezifanayo kwi-MP4V, njengeM4A, M4B , M4P , M4R , kunye neM4U (i-MPEG-4 Uhlu lwadlalwayo). Ezinye zeefayile azivumelekanga ngendlela efana neefayile ze-MP4V kuba zisetyenziswa nganye ngenjongo ekhethekileyo.
Indlela yokuguqula iFayile ye-MP4V
Endaweni yokufuna i-MP4V ukuya kwi-MP4 converter (okanye nayiphi na ifomathi ofuna ukuyigcina ividiyo), kufuneka ufumane umguquleli wevidiyo ngokusekelwe kwandiswa kwefayile eyenziwa yividiyo.
Umzekelo, ukuba unayo ifayile ye- 3GP esebenzisa i-codec ye-MP4V, khangela nje umguquleli wevidiyo ye-3GP.
Qaphela: Khumbula ukuba iifayile ze-M4V azifani ne-MP4V codec. Oluluhlu lwabaguquleli bevidiyo abakhulu bangasetyenziselwa ukufumana umguquleli we-M4V ukuya kwi- MP3 , ogcina iM4V kwi MP4, njl.
MP4 vs M4V vs MP4V
I-MP4, i-M4V, kunye ne-MP4V iifayile zendlela efanayo ukuze ubenokuziphosakela ngokulula kwifom ye fayile efanayo.
Nantsi indlela onokuyiqonda ngokukhawuleza ukungafani kwazo:
- MP4: I-codec kunye nefomathi yefomathi yokugcina i-audio nevidiyo kwifayile enye
- I-M4V: Ifayile ye-MP4 enokukhuselwa yi-DRM ikopi
- I-MP4V: I-MPEG-4 ephakamileyo Iimvolontiya zevidiyo ezingabanjwanga kwi-container MP4
Cofa kwikhonkco elingentla ngenjongo yolwazi olungaphezulu kwiifom kunye nakoluhlu lweenkqubo ezingavulwa kwaye ziguqule iiFayili ze-MP4 kunye nee-M4V.
