Daniel Almeida, kes tegeleb video kodekite arendamisega ettev\u00f5ttes Collabora, tutvustas Linuxi tuumaarendajatele uut rakendust, mis v\u00f5imaldab kasutada VP9 videode dekodeerimiseks riistvarakodeerijaid V4L2 alams\u00fcsteemis, mis v\u00f5imaldab juurdep\u00e4\u00e4su videote salvestusseadmetele nagu veebikaamerad ja TV-tuunerid. Rakenduse kood on t\u00e4ielikult kirjutatud Rusti keeles ja keskendub rkvdec ja hantro draiveritega t\u00f6\u00f6tamisele, mis v\u00f5imaldavad juurdep\u00e4\u00e4su videode dekodeerimise riistvara kiirendusele, mis on saadaval Rockchip ja Hantro kiipides. <\/p>\n

VP9 toe rakendava koodi V4L2 jaoks pikkus on umbes 2000 rida. Alternatiivse rakenduse loomise p\u00f5hjuseks Rusti keeles on soov saavutada lisakaitse, kasutades Rusti keele pakutavaid vahendeid m\u00e4lu ohutuks kasutamiseks koodis, mis sisaldab keerukate algoritmide rakendusi ja on m\u00f5eldud kasutajaruumi andmete t\u00f6\u00f6tlemiseks V4L2 liidest m\u00f6\u00f6da. Kuigi Rusti rakendus on praegu katsetamisprotot\u00fc\u00fcp, n\u00e4itasid Fluster paketiga testimisel, mis hindab dekodeerijate vastavust standardite spetsifikatsioonidele, C ja Rusti versioonid identseid tulemusi.
