Koleszar: VP8 Codec Optimization Update
[Posted June 15, 2010 by ris]
Google software engineer John Koleszar
looks
at VP8 development. "
For those of you eager to get involved, one
piece of low-hanging fruit is writing a SIMD version of the ARNR temporal
filtering code. Also, much of the assembly code only makes use of the SSE2
instruction set, and there surely are newer extensions that could be made
use of. There are also redundant code removal and other general cleanup to
be done; (Yaowu Xu has submitted some changes for these). At a higher
level, someone can explore some alternative motion search strategies in the
encoder. Eventually the motion search can be decoupled entirely to allow
motion fields to be calculated elsewhere (for example, on a graphics
processor)."
