Since open-sourcing the project, other partner companies and the open-source community have contributed to SVT-AV1. The teams have been working closely on SVT-AV1 development, discussing architectural decisions, implementing new tools, and improving compression efficiency. As mentioned in our earlier blog post, Intel and Netflix have been collaborating on the SVT-AV1 encoder and decoder framework since August 2018. SVT-AV1 is an open-source AV1 codec implementation hosted on GitHub under a BSD + patent license. $ ffmpeg -hide_banner -benchmark -i pedestrian_area_1080p25.y4m -c:v libaom-av1 -cpu-used 8 -usage realtime -crf 20 -y 4īench: utime=49.713s stime=0.230s rtime=16.By Andrey Norkin, Joel Sole, Mariana Afonso, Kyle Swanson, Agata Opalach, Anush Moorthy, Anne Aaron Set the SVT-AV1 configuration using a :-separated list of key=value parameters Log2 of number of tile rows to use (from 0 to 6) (default 0) Log2 of number of tile columns to use (from 0 to 4) (default 0) Initial Quantizer level value (from 0 to 63) (default 0) Constant Rate Factor value (from 0 to 63) (default 0) Set operating point tier (from 0 to 1) (default main) Encoding preset (from -1 to 13) (default -1) Look ahead distance (from -1 to 120) (default -1)

$ ffmpeg -hide_banner -h encoder=libsvtav1Įncoder libsvtav1 : It makes heavy use of threads and SIMD assembly thus better suited for live streaming (realtime encoding). SVT-AV1 is a mature implementation of a fast AV1 encoder.
