linaro aac encoder optimization

Hi, All, I would like to discuss about the next step of aac encoder optimization for linaro. Current situation is , 1. ffmpeg aac encoder is in bad shape and poor performance and encoding quality. 2. libfaac has license issue for release. 3. Android aac encoder is better for the performance and encoding quality, but it's Apache licensed.

Here's some options for me of the next steps for aac encoder optimization 1. Continue on ffmpeg aac encoder, but more effort is needed to a acceptable level. 2. Reuse Android aac encoder. Since it is Apache licensed. We need write a wrapper to use it in ffmpeg or write a gstreamer plugin to use Android encoder.

Any suggestions?
