uAVS2 is a fast encoder application library for China’s 2nd generation advanced video coding standard (AVS2), which was developed within the IEEE 1857 Working Group and issued as IEEE 1857.4. (More information about AVS2)

The coding performance of uAVS2 outperforms HEVC encoder x265 10~30% under similar coding speed. (More details)
