Do any Android or iOS music players support Opus?

Rockbox should have it fairly soon, and the decoder implementation is integer and reasonably efficient (much optimization is still needed however).

Any info on how well it performs? From what I heard about the Opus decoder for Windows (or generally x86/x64), it is much slower than decoders for other lossy formats. On a portable device battery usage is a really important issue for an audio format.

Its pretty well optimized now for ARM. The main thing remaining is to go through an write the FFT in assembly. Unfortunately, Opus does not use the same FFT lengths as other lossy formats, so it will need to be done from scratch. Once thats done it should be comparable to any other lossy format.
