This is evident in the rise of low-cost Android devices. The Android operating system relies heavily on libvpx for video playback and capture. By integrating VP9 support into the OS via libvpx, Google ensured that budget smartphones could stream high-quality video from YouTube or participate in video calls without requiring expensive hardware decoding chips dedicated to proprietary codecs like HEVC (H.265).
libvpx has a constant rate factor (CRF) mode. It tries to keep quality consistent without blowing up the bitrate. You can't send 4K HDR video over a 56k modem.
