* dsputil: Split audio operations off into a separate contextDiego Biurrun2014-06-22
|
* floatdsp: move scalarproduct_float from dsputil to avfloatdsp.Ronald S. Bultje2013-01-22
| | | | This makes the aac decoder and all voice codecs independent of dsputil.
* celp_math: rename ff_log2 to ff_log2_q15Mans Rullgard2012-10-20
| | | | | | | This name is more descriptive as the function returns a fixed-point value with 15 fraction bits. Signed-off-by: Mans Rullgard <mans@mansr.com>
* build: Restore dependency of acelp_filters.o on celp_math.oDiego Biurrun2012-08-27
|
* celp_math: Replace duplicate ff_dot_productf() by ff_scalarproduct_c()Diego Biurrun2012-08-27

* Don't include common.h from avutil.hMartin Storsjö2012-08-15

* dsputil: remove shift parameter from scalarproduct_int16Christophe GISQUET2012-03-07
| | | | | | | | | There is only one caller, which does not need the shifting. Other use cases are situations where different roundings would be needed. The x86 and neon versions are modified accordingly. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
* Remove unused code under G729_BITEXACT #ifdef.Diego Biurrun2011-07-20
| | | | G729_BITEXACT is never set, so the code is all dead code.
* Do not include mathematics.h in avutil.hMans Rullgard2011-07-03
