* dca: remove unused decode_hf function and quant_d tablesAlexandra Hájková2015-12-24
| | | | | They were superseded with their integer equivalents. Rename integer decode_hf to decode_hf.
* arm: dcadsp: implement decode_hf as external NEON asmJanne Grunau2014-02-28
|
* dcadec: remove scaling in lfe_interpolation_firChristophe Gisquet2014-02-28
| | | | | | | The scaling factor is constant so it is faster to scale the FIR coefficients in the tables during compilation. Signed-off-by: Janne Grunau <janne-libav@jannau.net>
* dcadsp: split lfe_dir casesChristophe Gisquet2014-02-07
| | | | | | | | | The x86 runs short on registers because numerous elements are not static. In addition, splitting them allows more optimized code, at least for x86. Arm asm changes by Janne Grunau. Signed-off-by: Janne Grunau <janne-libav@jannau.net>
* ARM: Move asm.S from libavcodec to libavutilJustin Ruggles2012-06-08
| | | | | This will allow for easier implementation of ARM-optimized functions in libraries other than libavcodec.
