„The spec consists largely of C code copy-pasted from the VP8 source code — up to and including TODOs, “optimizations”, and even C-specific hacks, such as workarounds for the undefined behavior of signed right shift on negative numbers. In many places it is simply outright opaque. Copy-pasted C code is not a spec. I may have complained about the H.264 spec being overly verbose, but at least it’s precise. The VP8 spec, by comparison, is imprecise, unclear, and overly short, leaving many portions of the format very vaguely explained. Some parts even explicitly refuse to fully explain a particular feature, pointing to highly-optimized, nigh-impossible-to-understand reference code for an explanation. There’s no way in hell anyone could write a decoder solely with this spec alone.“
Můžete se podívat sám, ale opravdu je tam spousta céčkového kódu včetně TODO. Bude se asi nejdříve muset asi napsat specifikace v2.0, kde bude způsob dekódování specifikovaný tak, aby se dál napsat dekodér bez zkoumání chování „referenčního“ dekodéru. http://www.webmproject.org/media/pdf/vp8_bitstream.pdf
