On2 announced some stuff with ARM a couple of years ago, apparently they worked together to both design and optimize VP8 for the ARM platform, including NEON.

And one of the low cost platforms for Android phones had a mysterious "On2" hardware acceleration block on their schematics at least 6 months ago.

A quote from ARM today on the VP8 announcement:

The efficient processing is helped by the fact that the VP8 codec is already optimized for Cortex-A/v7A class processors with the NEON SIMD (Single Instruction Multiple Data) engine. NEON allows the ARM CPU to work on multiple bits of data in parallel, and optimizations for ARM11 processors are also available
