           Version: 528+ (Nightly build)

See http://bellard.org/bpg/
BPG is a high-efficiency image compression format based on the HEVC Main 4:4:4 16 Still Picture Profile.
As you can see at http://xooyoozoo.github.io/yolo-octo-bugfixes/ (which uses a JS-based decoder), it achieves significantly better quality per size than JPEG.
BPG can be decoded natively using either libbpg (which in turn uses a minimal subset of the LGPL libavcodec and libavutil libraries), or with a hardware HEVC decoder on devices that support it.
