RE: Maxim's Atrac3plus decoder
Hi guys (and girlz),

my ATRAC3+ decoder has finally been posted to the FFmpeg project.

You can either follow up on our discussion here:
http://ffmpeg.org/pipermail/ffmpeg-devel...49248.html

or grab the latest Git snapshot, apply the above-mentioned patches and start to experiment with the decoder yourself.

Enjoy!
Best regards
Maxim

So CPU usage when playing Atrac3+ music will decrease for those of you who have been using the plugin, improving speed somewhat.

I'm pleased to hear that!

At the time being, you're running a scalar version of the decoder. Its speed can be increased by 15-20% by vectorizing several DSP functions.

Most modern CPUs include some kind of SIMD/Vector instructions in order to improve the performance of multimedia applications...

IIRC, Xuggler is just a Java wrapper for FFmpeg, isn't?
What do you need for Xuggler being able to decode ATRAC3+? A custom FFmpeg build?

Best regards
Maxim
