3GPP AAC+ High Efficiency Advanced Audio Codec v2 (HE-AAC+) Encoder Shared Library
|
|
|
|
|
|
|
|
|
|
3GPP released reference implementation of 3GPP AAC Advanced Audio -
|
|
|
|
|
(HE-AAC+) Encoder (3GPP TS 26.410 V8.0.0).
|

Reference implementation is available as a source code, but the code uses
|
|
|
|
|
#define to choose code options. In world of GNU-Linux, there is a common
|
|
|
|
|
practice to compile such code as a shared library.
|
|
|
|
|
|
|
|
|
|
Due to restrictive license, the reference implementation is not part of
|
|
|
|
|
this package and it is dowloaded from 3GPP during build. If you want to
|
|
|
|
|
build this package without network access, you either have to put the
|
|
|
|
|
original source code ZIP file to the unpacked wrapper code directory or
|
|
|
|
|
you have to use full source core (see below).
|
|
|
|
|
|
|
|
|
|
This package converts 3GPP TS 26.410 V8.0.0 reference implementation of HE-AAC+
|
|
|
|
|
encoder to a shared library. It has exactly the same API, but some calls
|
|
|
|
|
are wrapped by macros to call proper variant of the function.
|
|
|
|
|
|
|
|
|
|
For more see readme.txt and 26410-800.doc, which comes with the original code.
|
|
|
|
|
|
|
|
|
|
This wrapper fixes some bugs of original code.
|
|
|
|
|
I will accept patches for it, if 3GPP will not release fixed implementation.
|
|
|
|
|
|
|
|
|
|
To use package compiled by this code, you may need a license from 3GPP.
|
|
|
|
|
|
|
|
|
|
It is possible to distribute these packages in three source forms:
|
|
|
|
|
1. As a wrapper-only source (as you can build by "make extradist").
|
|
|
|
|
2. As a full source code including 3GPP code (as you can build by "make dist").
|
|
|
|
|
3. As a wrapper-only source accompanied by the original zip file.

Technical notes:
|
|
|
|
|
|
|
|
|
|
The code has only one branch with stereo implementation.
|
|
|
|
|
|
|
|
|
|
In addition to "make dist", you can also call "make extradist", which
|
|
|
|
|
builds distribution package containing LGPL wrapper only.
