De code van het project wordt verspreid<\/a><\/noindex> onder de BSD-licentie.<\/p>\n

Het AV1-formaat overtreft aanzienlijk x264 en libvpx-vp9 qua compressieniveau, maar door de complexiteit van de algoritmen<\/a><\/noindex> is er aanzienlijk meer tijd nodig voor codering (in termen van coderingsnelheid is libaom honderden keren langzamer dan libvpx-vp9 en duizenden keren langzamer dan x264). vereist<\/a><\/noindex> De coder rav1e biedt 11 prestatieniveaus, waarvan de hoogste snelheden mogelijk maken die dicht bij real-time codering komen. De coder is beschikbaar als zowel een commandoregelhulpprogramma als een bibliotheek.
