Nekuti inogadziriswa musoftware. Hardware video decoders inotarisa chete kune yakajairika runyorwa rwemafomati, uye AV1 iri kunze kwayo pazvigadzirwa zvakawanda, saka chero frame inodzokororwa neCPU. Pa desktop yenguva ino iyo isiri nyore; pafoni, laptop yakare kana smart TV inoonekwa seyakadonha mafomati, fan noise uye bhatiri drain.

Software rutsigiro yasvika nekukurumidza; Hardware rutsigiro chete anouya netsva maturusi, uye foni, TV kana mutambi pamberi pako anogona chete kusvikira. Kwairi rutsigiro iri kunyatsoita zvakanaka kupfuura format inoshandura, izvo ndizvo zvazvinoita zvakaoma kushandura muzvitoro uye zvakaoma kushandura kunze kwezvitoro kuti zvive zvakaenzana.

Zviri nyore - mabhuku anorarama mu metadata yebhokisi, saka kurodha kwenguva refu kunogona kuendeswa nechikamu sezviri nyore kupfuura nekudhonza mutsetse wekumhanya. Vanogona kurarama nekudzokorora mufananidzo muchikamu chinozivikanwa uye kudonha, zvisina kunaka, neimwe isina nzvimbo yekuisa. Kana mabhuku aripo, zvinokosha kuongorora kuti usati wasarudza chigadzirwa chigadzirwa kupfuura mushure.

Hapana munhu, mupfungwa yekuti zvinhu: specifications ndezvevanhu, implementations ndivo vakasununguka kunyora, uye hapana kambani inogona kuchinja mamiriro gare gare. Izvi ndizvo nei ichionekwa mu open-source zvinhu uye mu archiving mitemo, apo mufananidzo akadzora neumwe mutengesi ndemumwe ngozi. The trade is commercial support — it is often the format with the best specifications and the patchiest device compatibility.

Asi hazvina kuitika kare, uye zvinokosha kuziva kuti nei: kusvikira ndechimwe chiratidzo, uye bytes mukati mezvinyorwa zvakagadzirwa kuti zvive neimwe mhando. Kushandura zita refaira kunokonzera kuti zita riite serisina kunaka, uye chero chinhu chinovhura chinogona kubvisa faira kana kuisa mufananidzo. Mumwe mubvunzo unokosha ndewekuti kana iwe uchida kushandura zita refaira, iwe unofanirwa kuziva kuti ndeipi mhando yefaira iri.

Kukwira uye kushandurwa kwemhedzisiro kunogara paseva dzedu kwemazuva anenge 24, izvo zvinopa nguva yekurodha pasi mhedzisiro, uyezve zvinobvisa nekugadzirisa otomatiki. Kutumira kunoitika kuburikidza neHTTPS munzira mbiri. Hapana munhu anoverenga zvinhu, hapana chinhu chinonyorwa, uye hapana chinhu chinoendeswa kune mumwe munhu.

Zvimwe zvidiki zvinyorwa zvinotanga kugadzirwa mumasekondi mashoma. Zvidiki zvinyorwa zvinotanga kugadzirwa mumasekondi mashoma, uye zvinhu zvinotora nguva yakareba kuti zvigadziriswe: vhidhiyo kana vhidhiyo rakaomarara rinofanira kugadziriswazve frame neframe, kana kuti vhidhiyo kana vhidhiyo rakaomarara rinofanira kugadziriswazve nechiratidzo chekuziva, kana kuti vhidhiyo kana vhidhiyo rakaomarara rinofanira kugadziriswazve nechiratidzo chekuziva.
