M4V kuya AVI Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiguqula kanjani i-M4V ibe yi-AVI ngaphandle kokubuyisela umbhalo ongezansi wevidiyo?

I-remux ye-1 GB M4V ku-AVI ivame ukuqedwa ngamasekondi angama-5-15 ngaphandle kokulahlekelwa umgangatho. Ukuthuthukiswa M4V MP4 - H.264 noma HEVC nge AAC - nge optional Apple FairPlay DRM ne iTunes isiqephu metadata.

I-AVI ayinaso isixhaso esisemthethweni se-codecs yamanje, isilinganiso sefreyimu esiguqukayo, izihloko ezithambile noma amafayela angaphezu kuka-4 GB ngaphandle kokuhlaselwa, futhi i-chunk ngayinye i-overhead ibhoboza ifayela.

Kungani ihele lami M4V lingakwazi ukushintsha ku AVI?

Kuyinto evamile kakhulu i-DRM. Ezinye M4V izithombe zibhalwe ngokufihlakele ku-bitstream level yisitolo noma isofthiwe eyenza, futhi isithombe esibhalwe ngokufihlakele asikwazi ukucinywa yithu noma yinoma yini ngaphandle kwesitshixo selayisense. Izithombe ongazirekhodile, ozenzayo noma ozibhumele ngaphandle azikhuselwanga ziguqulwa ngokuvamile; ukuthenga okusemthethweni akuzokwenza, futhi akukho oguqulelayo angaba nesiqiniseko sokuthi kungashintshwa.
