Valid for ICS release as well, tested on :

Observed on Panda and iMX53 too.

If this is what I think it is, like mp3 decode done by dedicated unit instead of cpu, I don't think it's important in leb context if cpu can do it. If it means audio coming during accelerated video decode, deal with that on accelerated video decode bug, since it's legit if only video is accelerated and audio decode done by cpu.

Do TI release any hardware accelerated audio codecs? This particular feature often means that the apps processor can be shut down during a call, or when playing streaming video and audio. In Ubuntu it would be handled by GStreamer integration; not entirely sure how Android integration would be handled. What's available on the Nexus?

no. we don't provide any audio acceleration, and we entirely rely on ARM
open source codecs for any open source community. Some customers are using
h/w acceleration but we don't have any solution that we can share publicly.

OMAP4 has support for "low power music playback" using some specific h/w
that has large buffers for samples so you can shut down the CPU while
playing the 'decoded' samples. I am not how much of that is currently
available in our Linaro kernel though.

why exactly are you looking for that? are you interested in decoders or
encoders?

There is no hardware for audio codec both in i.MX53 and i.MX6.

Accelerated MM audio decoding for Snowball will be released in a 2012.04 pre-release as soon as possible. Small final issues with packing hinders it from getting into the 2012.03 release.

[Patrik Ryd (patrik-ryd)]

The vendor tarball intended for the 12.04 release should solve this for snowball
