Gudaha qaabka ISO Base Media File Format: Waa maxay sababta bateriga dhintay u dilo moov atamka¶

Si aad u fahamto sababta 30-daqiiqo, 25-gigabyte 4K xafladda arooska fiidiyaha ayaa noqda mid aan la akhrin karin marka uu batarigu dhinto daqiiqadda 29:59, fiiri anatomy gudaha gudaha ee .MP4 ama QuickTime .MOV fayl

Mid walba .MP4 iyo .MOV faylka waxaa loo qaabeeyey sida kala sareynta "sanduuqyada" ama "atomamka", mid walba waxaa ka horeeya 4-byte integer iyo aqoonsiga 4-byte ASCII (FourCC):

1. ftyp (Faylka Nooca Sanduuqa - Bytes 0x00 ku 0x1F bilowga faylka):
2. Qor isla markiiba aad riixdo badhanka Diiwaangelinta. Wuxuu aqoonsadaa qeexida weelka (sida mp42, isom, qt, ama Sony XAVC).
3. mdat (Sanduuqa Xogta Warbaahineed - Waxa uu qaataa 99.8% faylka oo dhan):
4. Sida dareemaha kamaraduhu uu qabto muqaal, makarafoonkuna uu qabto maqal, cod-bixiyaha hardware-ka waxa uu daadiyaa fiimyada fiidyaha ee la cufan (I-frames / Keyframes, P-frames, B-framesiyo baakado maqal ah (PCM ama AAC) si joogto ah u galay mdat sanduuqa ku yaal kaarka SD.

6. moov (Sanduuqa Metadata ee filimada - Waxa la qoray oo keliya dhamaadka marka aad riixdo Jooji):
7. Sababtoo ah kamaradu horay uma sii saadaalin karto ilaa inta aad duubi doonto ama inta byte ee jir kasta oo variable-bitrate uu qaadan doono, ma qori karto miiska tusmada bilowga faylka. Taa baddalkeeda, kamaradu waxay ku kaydisaa tusaha jirku chip-ka DRAM ee gudaha marka la duubayo.
8. Kaliya marka aad riixdo badhanka **Stop *** (ama marka maaraynta baytariyada kamaradu IC ay kiciso hoos u dhigista korantada yar ee boqolkiiba 2) ayay kamaradu daadinaysaa tusmada DRAM ilaa dhamaadka dhamaadka .MP4/.MOV faylka sida moov atom, kaas oo ka kooban lix miisas-hoosaadyo gudaha ah moov -> trak -> mdia -> minf -> stbl (Tusaale Sanduuqa Shaxda):

Su'aalaha soo noqnoqda¶

Waa maxay sababta VLC Media Player ee ku dhex dhisan "Faylka Fiidiyowga Dayactira" u soo baxay ku guuldareystay inuu hagaajiyo aan dhammayn .MP4?¶

Ciyaartoyga VLC ee tooska ah "Faylka AVI burburay ama aan dhamaystirnayn - Dhis index ka dibna ciyaar" sifada waxaa loogu talagalay si gaar ah dhaxalka `.AVI` (`RIFF`) weelasha, AAN ahayn warbaahinta casriga ah ee ISO Base Media `.MP4` ama `.MOV` faylasha kamaradaha. In ah `.AVI` faylka, qaab kasta oo shakhsi ah oo ku dhex jira qulqulka xogta wuxuu leeyahay sumad cad oo 4-byte ah oo ASCII ah (`00dc` muuqaal ahaan, `01wb` loogu talagalay maqalka), markaa VLC waxay si indho la'aan ah u sawiri kartaa `.AVI` iyada oo aan la garanayn goobaha kamarada. In ah `.MP4` ama `.MOV` file, cayriin `mdat` culayska la saarayo waxa uu ka kooban yahay weel eber ah calamadaha, iyo cabbiraadaha bilowga codec (`SPS` iyo `PPS` miisaska gudaha `avcC`/`hvcC`) ku noolaado gudaha kaliya ee maqan `moov` atamka dhamaadka faylka. Taasi waa sababta VLC aysan u ciyaari karin mid aan dhameystirneyn `.MP4`, iyo sababta ay tahay inaad isticmaasho `untrunc` ama `recover_mp4` oo leh muuqaal tixraac caafimaad leh oo isla kamarad la mid ah si loo bixiyo kuwa maqan `SPS/PPS` naqshadeynta.

Maxaa dhacaya haddii aanan haysan fiidiyoow kale oo ka soo baxay toogashadaas saxda ah si aan u isticmaalo "Faylka Tixraaca Caafimaadka"?¶

Uma baahnid muuqaal isku maalin ama isku meel ah. Waxaad qaadan kartaa isla kamaraddaas saxda ah, drone-ka, ama GoPro hadda (xitaa toddobaadyo ka dib), geli kaar ka duwan, kaarka SD maran, hubi in menu-ka kamarada loo dejiyay isla Qaraarka saxda ah, Framerate, Codec (`H.264` vs `H.265`), Qoto dheer (`8-bit` vs `10-bit`), iyo Qaab maqal ah oo aad isticmaalaysay markii shilku dhacay, oo duub muuqaal 10-ilbiriqsi ah miiskaaga. Goobkaas-cusub ee 10-ilbiriqsi ah wuxuu yeelan doonaa isku mid `stsd` (`avcC`/`hvcC`) Qaamuuska madaxa codec ee uu u baahan yahay `untrunc` iyo `recover_mp4` si loo furo faylkaaga jaban.

Sideen ku ogaan karaa haddii "Website-ka Dayactirka MP4 ee Online-ka ah ee bilaashka ah" (restore.media, fix.video, cleverfiles) waa nabad, mise haddii ay isku dayayaan inay i khiyaaneeyaan?¶

Inta badan shabakadaha dib-u-habaynta fiidyaha ee khadka tooska ah waxay ku shaqeeyaan duubabka daruuriga ah ee ku wareegsan isla isha furan `untrunc` iyo `recover_mp4` / `FFmpeg` Algorithms-ka lagu sifeeyay hagahan, aan kuu ogolaado inaad soo rogto faylkaaga jaban iyo faylka tixraaca, ku tuso 4 sawir gacmeed oo muuqaal hoose leh oo caddaynaya in fiidyahaagu yahay mid dib loo soo celin karo, ka dibna dalbado $49 ilaa $149 fayl kasta si aad u soo dejiso dayactirka `.MP4`. Kahor intaadan bixin bogga internetka, socodsii isha furan ee bilaashka ah `anthwlock/untrunc` ama `recover_mp4` CLI naftaada kumbiyuutarkaaga; ma aha oo kaliya 100 boqolkiiba bilaash ah, waxaad sidoo kale ka fogaataa inaad 30 gigabytes ee arooska gaarka ah, macmiilka, ama sawirada sharciga ah ee server-ka saddexaad ee daruuraha.

Fiidiyowgeyga la dayactiray si fiican ayuu u ciyaaraa, laakiin 1.5-kii ilbiriqsi ee ugu dambeeyay isla markii ay diyaaraddu ku dhufatay geedka waa la la'yahay. Miyaa la soo celin karaa 45-kii ugu dambeeyay?¶

Badanaa maya, oo waa kan sababta physics hardware-ka sababta: Kamaradaha casriga ah iyo diyaaradaha aan duuliyaha lahayn waxay isticmaalaan giraanta SDRAM ee xawaaraha sare leh ee u dhexeeya processor-ka sawirka (`ISP / Encoder`) iyo baska kaadhka SD. Sida kaamiradu u codeeeyso muqaalka koox sawiro ah (`GOP`, sida caadiga ah 15 ilaa 60 fiimyo dheer), waxa ay ku haysaa kaydka hadda jira ee 1-ilaa-2-second ee RAM kacsan ka hor inta aan lagu daadin megabyte-ka badan ee ku dilaaca kaadhka SD ee NAND. Korantada degdega ah ee baytarigu waxa uu hoos u dhacayaa eber inta lagu jiro shil adag, wax kasta oo xayndaab ah ayaa ku fadhiya SDRAM kacsan (sida caadiga ah 0.5 ilaa 2.0 ilbiriqsi ee u dambeeya ee muuqaalka) way baaba'aan ka hor inta aysan waligood ka gudbin biinanka kaararka SD. Wax kasta oo horeyba u soo baxay `mdat` atomka kaadhka ayaa ah waxa la samatabbixiyo.

Sideen uga hortagi karaa mid aan dhammaanayn .MP4 masiibooyinka arooska muhiimka ah, dukumentiyada, ama toogashada shineemo mustaqbalka?¶

Shaleemo-garafayaasha xirfadleyda ah iyo isku-dariyeyaasha dhawaaqa waxay isticmaalaan saddex qalab ilaalin oo ka hortagaya in la waayo `moov` atamka: (1) Isticmaal Dual-Slot isku mar isku-gudbinta/kabka duubista (`Slot 1 + Slot 2 Simultaneous`): Haddii kaadhka SD ee kulaylka badan ama gabowga uu ka dhaco khadka tooska ah dhex-qaadista, kaarka labaad wuxuu hayaa duubista wuxuuna u dhammeeyaa si nadiif ah. (2) Ku duub MP4 jajaban (`fMP4`), `.MXF`, ama Qaabab Madax-Bannaaneed`Blackmagic RAW .BRAW` ama `ProRes RAW`) meesha laga heli karo: ka duwan heerka caadiga ah `.MP4`/`.MOV` kaas oo sugaya ilaa dhamaadka dhamaadka 60-daqiiqo qaadashada si loo qoro hal keli ah `moov` atom, MP4 oo jajaban (`fMP4`, oo ay adeegsato qaabka iyo baahinta MP4-ka Hybrid Studio OBS `.MXF` duubayaasha) wuxuu qoraa madax-yar (`moof` - Filimka Fragment Atom) 2 ilbiriqsi kasta oo dhan faylka, markaa haddii korontadu go'do inta lagu jiro duubista 2-saac ee gudaha `fMP4` ama `.MKV`, Boqolkiiba 100 fiidyowgu isla markiiba wuu ciyaaraa iyada oo aan lahayn qalab dayactir ah. (3) Had iyo jeer baytariyada dummy-ka-xidhka ah iyo fiilooyinka USB-C PD ama V-Mount ee dibadda si gimbal ama tripod aysan u dhicin inay korontadu dhexda qaadato.
