* Include libFDK ppc headers in make distMartin Storsjo2014-11-041-0/+1

* Extend the GetInvInt table to 80 elementsMartin Storsjo2014-08-013-10/+14
| | | | | | | | | | 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.
* Extend GetInvInt to support values up to 54Martin Storsjo2014-07-292-6/+7
| | | | | | | | | For sample rates >= 64 kHz with short blocks, the largest sfb width is 36, which after grouping can be multiplied with 3, ending up as 108. GetInvInt needs to be able to support the largest grouped sfb width, divided by two (3 * 36 / 2 = 54). This fixes VBR encoding with sample rates >= 64 kHz.
* Add support for waveformatex filesMartin Storsjo2014-06-231-1/+11
| | | | This is used for multichannel wave files.
* Support reading sox style piped wav filesMartin Storsjo2014-06-231-1/+1
| | | | | Sox writes the RIFF header size as a very large number, instead of as 0 as in libavformat.
* Use skip instead of fseekMartin Storsjo2014-06-231-2/+8
| | | | | | | | fseek(SEEK_CUR) doesn't work for nonseekable streams (such as pipes). Only do this for skipping past small chunks; don't use it for skipping past the actual data for non-streamed input.
* Allow reading wav files with a 0 bytes RIFF chunkMartin Storsjo2014-06-231-1/+5
| | | | | This is required in order to read streamed wav files produced by the libavformat wav muxer.
* Allow opening stdin when "-" is specifiedMartin Storsjo2014-06-231-2/+6

* Support streamed wav files with a 0 bytes data chunkMartin Storsjo2014-06-231-1/+7

* Use AC_SEARCH_LIBS to search for a library containing math functionsMartin Storsjo2014-06-231-1/+1
| | | | | Even though the previous mechanism worked, this should be more correct.
* Fix AIX buildMark Harris2014-05-261-2/+2
| | | | | | | Fix AIX build failure with IBM xlC compiler due to conflicting definition of M_PI. The libSYS/include/genericStds.h definition is guarded with #ifndef M_PI, but was included before <math.h> which defines M_PI with more significant digits.
* Add ppc optimization for clz and fixmulMark Harris2014-05-265-1/+232
| | | | | Optimize ppc/ppc64 similar to i386/x86_64, approximately doubling encoding speed on a Power Mac G5 running OS X 10.5.8.

* 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.
* Revert "Avoid too big changes in isScale"Martin Storsjo2013-11-011-9/+0
| | | | | | | | 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

* | 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.
