Kutulutsa koyamba kwa rav1e, encoder ya AV1 ku Rust

chinachitika kutulutsa koyamba kwa encoder yatsopano yamakanema ochita bwino kwambiri AV1 - mvu1e 0.1, yopangidwa ndi anthu a Xiph ndi Mozilla. Encoder imalembedwa mu Rust ndipo imasiyana ndi encoder ya libaom pakukulitsa kwambiri liwiro la encoding ndikuwonjezera chidwi pachitetezo. Project kodi wogawidwa ndi pansi pa layisensi ya BSD.

Mtundu wa AV1 ndiwowonekera kutuluka x264 ndi libvpx-vp9 malinga ndi mulingo wa kukakamiza, koma chifukwa cha zovuta zama algorithms pamafunika nthawi yochulukirapo yokhotakhota (mu liwiro la encoding, libaom ili kuseri kwa libvpx-vp9 kangapo, ndi nthawi masauzande kumbuyo kwa x264).
Encoder ya rav1e imapereka magawo 11 a magwiridwe antchito, apamwamba kwambiri omwe amapereka pafupi ndi liwiro lenileni la encoding. Encoder imapezeka ngati chida cholamula komanso ngati laibulale.

Zinthu zazikulu zonse za AV1 zimathandizidwa, kuphatikiza chithandizo
mafelemu amkati ndi kunja (mkati- и yapakati-mafelemu), 64x64 superblocks, 4:2:0, 4:2:2 ndi 4:4:4 chroma subsampling, 8-, 10- ndi 12-bit color deep encoding, RDO (Rate-distortion optimization) kusokoneza kukhathamiritsa, mitundu yosiyanasiyana yolosera zakusintha kwa interframe ndikuzindikiritsa masinthidwe, kuwongolera kuchuluka kwamayendedwe ndikuzindikira kuchepa kwa zochitika.
