But, as we’ve implemented AV1 for mobile RTC , we’ve also had to address a number of challenges including scaling, improving video quality for low-bandwidth users as well as high-end networks, CPU and battery usage, and maintaining quality stability. As seen in Figure 1, some calls operate in very low-bandwidth conditions.
