VP8 Codec


VP8 is an open source, royalty-free, video codec standardized by Internet Engineering Task Force (IETF), as RFC 6386, in the year 2011. It has been made available by Google under BSD license and is the default video codec in the Google WebRTC application. The codec operates on 8-bit YUV 420 progressive scans with resolutions up to 4K. The Encoder has an inhenrent support for multi-core implementation (up to 8 cores) and has an in-loop deblocking filter. The encoding complexity can be controlled using the cpu-use parameter which provides a lot of flexibility for real-time applications. The Decoder supports packet loss concealment. VP8 codec can be used in a wide range of applications such as video-conferencing, streaming, and storage applications.
