Fraunhofer IIS FDK e499f9485e Adjust VBR mode depending on given peak bitrate and fix crash recovery usage.
Operating the FDK encoder in A2DP with variable bitrate mode
configuration resulted in unexpected encoder return value AACENC_ENCODE_ERROR.

Due to peak bitrate restriction the encoder quite often runs into requantization.
In case the bitrate constraint is not fulfilled, the so-called crash recovery is
used as final emergency step. The crash recovery reduces the overall bit
consumption considering the given number of bits to be saved. The bit difference
is extracted from audio element structures. In VBR mode the element wise bit
consumption state was not updated since there is typically no bitrate limitation
required.

The patch solves the choppy audio problems and increases audio quality for
AAC VBR encoding.

The changes in FDKaacEnc_QCMain() ensure that audio element bit info is always
updated. This is achieved by always calling FDKaacEnc_BitResRedistribution()
and FDKaacEnc_prepareBitDistribution() with maxBitsPerFrame variable as total
bits parameter.
Furthermore, VBR assumes a certain target bitrate which is used for internal
configuration and limitations. In case the peak bitrate parameter is less than
the VBR mode target bitrate the maximum of both bitrate configurations was used.

The function FDKaacEnc_AdjustVBRBitrateMode() is added to adjust the encoder
internal VBR mode to a desired target bitrate less than given peak bitrate.
It is possible that the peak bitrate is very close to the desired target bitrate.
The virtual available bitreservoir is quite low and the encoder would run quite
often into requantization with needless audio quality reduction. In such a
configuration, it is a better choice to use the CBR targeted threshold adaption
to avoid audio quality reduction.

In FDKaacEnc_Initialize(), there was already a bitResMode selection depending
on available bitreservoir for CBR. This selection will now also be used for VBR.
In case the bitResMode is AACENC_BR_MODE_FULL and VBR mode is selected, the VBR
threshold adaption is used. Otherwise, CBR threshold adaption strategy is used
and therefore, no unnecessary fill bits are written.

Dan Willemsen 6e8330732f Remove __DATE__/__TIME__
Building __DATE__/__TIME__ into the binaries means that every build will
create different binaries, even if all the sources are identical. This
also means that any libraries including this one will need to be patched
during every OTA.

Nothing appears to use the build_date/build_time fields, so just replace
them with empty strings.

Martin Storsjo 9a3234055a Extend the GetInvInt table to 80 elements
This is a bug fix patch from Fraunhofer, amending/replacing/extending
the previous commit which only extended the table to 55 elements.
(In my previous fix, 55 seemed to be enough for the issue at hand at
least. A few of the coefficients had slightly different rounding than
what Fraunhofer had used though).

This will show up in AOSP in the next code drop as well.

Martin Storsjo 164fc98be1 Include the encoder library version in the publicly installed header
This allows callers to conditionally use new API features without
breaking compatibility with the earlier versions of the library.

Martin Storsjo b41a6f9e81 Revert "Avoid too big changes in isScale"
This reverts commit 226601a8d9.

This change doesn't seem to be necessary any longer, a proper
fix seems to be included upstream now in
60a27b7fe5.

Jean-Michel Trivi 9f455bea1c Encoder ELD auto configurator

   - Introduce ELD auto configurator to get predefined configuration at given
     bitrate and sampling rate. The configurator selects SBR on/off and if SBR
     enabled distinguishes between dualrate and downsampled SBR. In default
     configuration the ELD auto configurator is enabled.

     The parameter is optional and default configuration is implicit signaling
     for dualrate SBR as before. In case of downsampled SBR and HE-AAC explicit
     signaling is configured as default.
