* Include autogen.sh when building distribution packagesMartin Storsjo2013-11-251-0/+1

* Include the encoder library version in the publicly installed headerMartin Storsjo2013-11-011-0/+3
| | | | | This allows callers to conditionally use new API features without breaking compatibility with the earlier versions of the library.
* Avoid casting arbitrary values to an enumMartin Storsjo2013-11-011-6/+6
| | | | | | | | | | | | | | The enum only contains the constant values 0, 1 and 2. This produces the warning "comparison of constant 6 with expression of type 'PS_RESOLUTION' is always false" in clang for the first check in the getNoBands function (but apparently not for the second one even though mode>=3 shouldn't ever happen for a valid PS_RESOLUTION value either). This could allow the compiler to completely remove the conditions that shouldn't be able to occur even though they actually are used and are necessary. By passing the value as UINT instead, it is clear to the compiler that all the checks are necessary.

| | | | | | | | This reverts commit 226601a8d9bce81455e161a0e26051d2f22c5d7a. This change doesn't seem to be necessary any longer, a proper fix seems to be included upstream now in 60a27b7fe5bf2c3b07ae7f679ca67c0c5cba3b00.

| * Encoder quantizer fixJean-Michel Trivi2013-08-202-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | AAC Encoder: Saturate quantizer shift value to prevent undefined behaviour. In very rare cases the shift value 'totalShift = (16-4)-(3*(totalShift>>2))' can be greater than accu data width. If you apply a shift with more then 31 bit the result depends on the architecture and is not defined in C. For certain platforms zeros are shifted in. That would be our desired behaviour. On other platforms the shift will be applied as modulo. For example >>34 would be applied as >>2. To prevent this discrepancy the shift value is limited/saturated to DFRACT_BITS-1. 'accu >>= fixMin(totalShift,DFRACT_BITS-1)'. Bug 9428126 Change-Id: I27177654c4dc22cf899bc35dad9cdd040dccb02d

| | | | | | | | | | | | | | | | | | | | This makes sure we read the right array element, corresponding to all other array accesses in the same function, and all other use of the isBook array elsewhere in the library. This makes the fix in the previous commit ("Avoid too big changes in isScale") work as intended, fixing other samples that triggered assertions.
* | Avoid too big changes in isScaleMartin Storsjo2013-03-181-0/+9
| | | | | | | | | | | | | | | | | | | | These values are delta encoded, but only steps [-60,60] are possible to encode. If the difference between two values are bigger than that, we end up with a sequence we are unable to encode. This fixes crashes on certain stereo samples at higher bitrates.

* | Don't try to shift more bits than the variable lengthMartin Storsjo2013-02-171-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Shifting by more than (or equal to) the variable length is undefined in C. This caused the quantized spectrum values to remain unshifted, causing loud beeps in some samples. The exact same change was originally applied in 657456949 (for AOSP) and in 24021f190 (in the separate fdk-aac repo), but was overwritten and silently reverted by the new upstream code drop for Android 4.2 in 381d69840a. After the code drop, I chose not to reapply this change since the crashes that it fixed had been fixed in other ways upstream and I was unable to reproduce them after the new code drop.

| | * Don't zero out spec coeffs before doing the final IMDCT.John Grossman2012-09-121-4/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Addresses bug 7140347. When flushing the decoder, you need to make sure to zero out any lingering spectral coefficients as well as zero out the overlap buffer state after decoding the final access unit. Zeroing out the spec coefficients *before* you decode the last block, however, seems like a mistake. If the final block contains any useful information for the stream, then you end up outputting the overlap portion of the second to last decoded block combined with zeros. Because of the shape of the second to last block's windows, this results in what appears to be a fade out, but actually is a zero'ed out final block.

Modified file(s): libAACdec\src\aacdec_tns.cpp libAACdec\src\aac_rom.h libAACdec\src\aac_rom.cpp - Fixed ELD synthesis QMF filterbank scaling for downsampled SBR. Modified file(s): libFDK\src\qmf.cpp * AAC-Encoder - Fixed bit rate limiting for lower limit as introduced in the Delivery 2012-05-11. Modified file(s): libAACenc\include\aacenc_lib.h libAACenc\src\aacenc.h libAACenc\src\aacenc.cpp libSBRenc\src\sbr_rom.h libSBRenc\src\sbr_rom.cpp - Allow negative prediction gain as meaning that there is no coding gain. Make use of scaleValueSaturate in gauss window calculation. Modified file(s): libAACenc\src\aacenc_tns.cpp - Added energy saturation to prevent overflow in short blocks. Modified file(s): libAACenc\src\grp_data.cpp - Perform scalefactor adaption in case quantized lines are out of valid range. Modified file(s): libAACenc\src\quantize.cpp - Interrupt quantization loop when no spectral data is available. Adjustments in bitreservoir adaption. Modified file(s): libAACenc\src\qc_main.cpp - Indroduced dynamic scaling in none missing harmonic energy lowering compensation. Modified file(s): libSBRenc\src\env_est.cpp * FDK-Library - Fixed saturation for negative values in scaleValueSaturate.
