Intel yakaburitsa kuburitswa kweSVT-AV1 1.0 (Scalable Vhidhiyo Technology AV1) raibhurari, iyo inopa imwe encoder uye decoder yeAV1 vhidhiyo encoding fomati, iyo inoshandisa iyo hardware parallelization yemakomputa aripo muIntel CPU yemazuva ano. Chinangwa chikuru cheSVT-AV1 ndechekuwana mwero wekuita wakakodzera pane-iyo-inobhururuka vhidhiyo transcoding uye kushandiswa muvhidhiyo-pa-inoda (VOD) masevhisi. Iyo kodhi inogadzirwa neiyo OpenVisualCloud purojekiti, iyo zvakare inovandudza iyo SVT-HEVC uye SVT-VP9 encoders, uye inogoverwa pasi peiyo BSD rezinesi.
SVT-AV1 inoda inokwana chizvarwa chechishanu Intel Core processor (Intel Xeon E5-v4 uye itsva CPUs). Kuti uvhare 10-bit AV1 hova mumhando ye4K, 48 GB ye RAM inodiwa, 1080p 16 GB, 720p 8 GB, 480p 4 GB. Nekuda kwekuoma kwemaalgorithms anoshandiswa muAV1, kukodha fomati iyi kunoda zviwanikwa zvakawanda kupfuura mamwe mafomati, izvo zvisingatenderi kushandisa yakajairwa AV1 encoder yechokwadi-nguva transcoding. Semuyenzaniso, stock encoder kubva kuAV1 project inoda 5721, 5869, uye 658 times more computation pane x264 (main profile), x264 (high profile) uye libvpx-vp9 encoders.
Pakati pekuchinja mukuburitswa kweSVT-AV1 kutsva:
- Yakawedzerwa tsigiro yeS-maframes (Switching Frame), mafuremu epakati ane izvo zvinogona kufanotaurwa zvichibva pamaferemu akadhindwa ereferenzi kubva kuvhidhiyo imwechete pakugadziriswa kwepamusoro. S-mafuremu anotendera iwe kuti uwedzere kudzvanya kwekuita kwehupenyu hova.
- Yenguva dzose bit rate (CBR) encoding control mode yakawedzerwa kuve nechokwadi kushoma latency.
- Yakawedzerwa rutsigiro rwekupfuura ruvara subsampling chinzvimbo ruzivo.
- Yakawedzera kugona kusvetuka denoising mifananidzo mushure mekushomeka synthesis.
- Tsigiro yekukurumidza decoding yakawedzera kusvika kuM0-M10 presets.
- Kushandiswa kwakareruka kwe "--fast-decode" sarudzo uye yakagadziridza yekutanga nhanho yekukurumidza decoding.
- Kuvandudzwa kwemhando yekuona kwe encoding mhedzisiro.
- Optimized memory kushandiswa.
- Yakawedzera mamwe optimizations zvichienderana neAVX2 mirairo.
