In OpenCORE 2.0, the wrapper component was available. In OpenCORE 2.1, required modifications in the author engine, omx encoder node, and composer nodes to make use of an aac encoder have been provided. So, anybody interested to plugin an AAC encoder can do so via the framework.
I don't think the AAC encoder library itself will be part of OpenCORE. -Ravi On Mar 3, 5:14 am, Andy Quan <[email protected]> wrote: > Question on AAC encoder OMX support: > - Added OMX AAC encoder support in the OMX encoder. > > It seems OMX wrapper for AAC encoder is already there in opencore 2.0 > release.
