WebM project released the fifth generation of the hardware encoder for VP8, internally known as “Evergreen”. In this release they focused on improving the real-time communication features and on optimizing the encoding speed and visual quality.
In particular, they have now enabled temporal and spatial scalability for VP8 video coding, a valuable feature for live streaming, multi-way video conferencing and security applications.
Reportedly, there are no companies offering ITU-T/MPEG SVC (scalable video coding) hardware encoders for chipset manufacturers at the moment. With this release, VP8 now offers scalable coding at the hardware level.
