Kokunye sikhulume ngakho FFmpeg. Kuyinto Ithuluzi lomthombo ovulekile umsebenzi walo ukukhipha amafomethi wevidiyo. Ithuluzi livame kakhulu kunalokho okungahle kubonakale, noma kwezinye izimo lisebenza njengezithunzi njenge kuyinjini yabadlali bevidiyo abadumile.
Ezinsukwini zakamuva kukhishwe isibuyekezo esisha, esimele inguqulo 4.0. Ngaphezu kokulungiswa okwaziwayo ukwenza noma ikuphi ukudlala kube uketshezi oluningi, kulokhu kuthuthukisa ukuhambisana namakhadi wehluzo lokho kudale kuze kube manje okunye ukungahambelani. Manje inqubo ayincikile kakhulu kuma-processor, idlulisa umsebenzi kumakhadi wehluzo.
Ngakho-ke manje kuyashesha futhi kusetshenziswa amandla amancane lapho udlala amavidiyo athile, ekuqaleni awahambisani nesidlali esivame ukusisebenzisa.
Kuze kube manje, ihluzo zeNvidia ezisekelwa yi-NVDEC ziphikisiwe. Ngakho-ke, ukuhambisana ne-HEVC / H.265 entsha kufanele kuphelele, kungakhi ukuzibophezela ohlelweni oluzama ukukhiqiza kabusha. Kumaprosesa we-AMD, ukuthuthuka kuqala kusuka ku-H.264 futhi-ke, uH.265 uyabuyekezwa.
Ingxenye engemihle ukuthi ayitholakali ngqo kwi-Mac. okwesikhashana, singasebenzisa I-VideoToolBox nomyalo wokugcina wokusebenzisa ikhadi lehluzo hhayi iprosesa. Umyalo ulandelayo:
ffmpeg -i video.mp4 -c:v h264_videotoolbox out.mp4
Umehluko ubaluleke kakhulu, ikakhulukazi kuma-Mac akamuva kakhulu. Ku-2017 15-inch MacBook Pro eguqula ividiyo ibe yi-HEVC / H.264 kungathatha cishe imizuzwana engama-40. Ngemuva kokubuyekeza i-FFmpeg, inqubo ithatha imizuzwana engu-6 nje.
Ngalezi zivinini zokuguqula, ukusetshenziswa kwe-H.265 kuzokwanda. Khumbula ukuthi iyi-codec egcina ikhwalithi efanayo esikhaleni esincane. Okubi yisikhathi sokuguqulwa. Ngamandla akhonjisiwe kulesi sibuyekezo, ifomethi ye-H.265 izohamba phambili ngokushesha okukhulu.
