MediaCoder (build 3999) can now encode with the Enhanced 3GPP AAC+ encoder again. The encoder is updated (with the latest 3GPP AAC+ encoder reference code) and patched with some minor optimizations and AAC/ADTS container support by me. The Enhanced 3GPP AAC+ encoder is able to produce low-bitrate (16kbps to 48kbps) AAC+ with Parametric Stereo optionally.

The 0.6.0.3999 update contains the encoder. The x64 update contains the 64-bit version of the encoder which has an approximate 30% speedup than the 32-bit version.
