2.0.0
|
||||
- Major update in the upstream source base, with support for new
|
||||
profiles and features, and numerous crash/fuzz fixes. The new
|
||||
upstream version is referred to as FDKv2, thus skipping the
|
||||
major version 1 and syncing the fdk-aac major version number to 2.
|
||||
|
||||
0.1.6
|
||||
- Lots of minor assorted crash/fuzz fixes, mostly for the decoder but
|
||||
also some for the encoder
|
||||
|
||||
0.1.5
|
||||
- Updated upstream sources
|
||||
- Fixed building with GCC 3.3 and 3.4
|
||||
- Fixed building with GCC 6
|
||||
- AArch64 optimizations
|
||||
- Makefiles for building with MSVC
|
||||
- Support building the code in C++11 mode
|
||||
|
||||
0.1.4
|
||||
- Updated upstream sources, with minor changes to the decoder API
|
||||
breaking the ABI. (Calling code using AUDIO_CHANNEL_TYPE may need to
|
||||
be updated. A new option AAC_PCM_LIMITER_ENABLE has been added, enabled
|
||||
by default, which incurs extra decoding delay.)
|
||||
- PowerPC optimizations, fixes for building on AIX
|
||||
- Support for reading streamed wav files in the encoder example
|
||||
- Fix VBR encoding of sample rates over 64 kHz
|
||||
|
||||
0.1.3
|
||||
- Updated upstream sources, with a number of crash fixes and new features
|
||||
(including support for encoding 7.1)
|
||||
|
||||
0.1.2
|
||||
- Fix a few more crashes
|
||||
- Include dependency libs (such as -lm) in the pkg-config file
|
||||
|
||||
0.1.1
|
||||
- Updated to a new upstream version from Android 4.2, fixing a lot of crashes
|
||||
- Cleanup of autotools usage
|
||||
- Make sure the shared library links to libm if necessary
|
||||
- Performance improvements on x86
|
||||
- Added support for WG4/DVD audio channel mappings
|
||||
- Minimized the differences to upstream
|
||||
- Added an example encoder tool
|
||||
|
||||
0.1.0
|
||||
- Initial release of fdk-aac
|
||||
- autotools based build system
|
||||
- Enable setting VBR bitrate modes
