/*!\defgroup vp8 VP8
* \ingroup codecs
* VP8 is vpx's newest video compression algorithm that uses motion
* compensated prediction, Discrete Cosine Transform (DCT) coding of the
* prediction error signal and context dependent entropy coding techniques
* based on arithmetic principles. It features:
* - YUV 4:2:0 image format
* - Macro-block based coding (16x16 luma plus two 8x8 chroma)
* - 1/4 (1/8) pixel accuracy motion compensated prediction
* - 4x4 DCT transform
* - 128 level linear quantizer
* - In loop deblocking filter
* - Context-based entropy coding
