A technical analysis of VP8

Jason Garrett-Glaser has posted what he claims is The first in-depth technical
analysis of the VP8 codec. The "in-depth" part is certainly right.
"Overall, VP8 appears to be significantly weaker than H.264
compression-wise. The primary weaknesses mentioned above are the lack of
proper adaptive quantization, lack of B-frames, lack of an 8x8 transform,
and non-adaptive loop filter. With this in mind, I expect VP8 to be more
comparable to VC-1 or H.264 Baseline Profile than with H.264. Of course,
this is still significantly better than Theora, and in my tests it beats
Dirac quite handily as well." (Thanks to Martin Jeppesen).
