* avutil/softfloat: Move av_sincos_sf() from header to c fileMichael Niedermayer2015-06-05
| | | | | | | The function is quite big and trigonometric functions should not really be used in speed critical code Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

* libavutil/softfloat: Fix av_normalize1_sf bias.Nedeljko Babic2015-06-04
| | | | | | | av_normalize1_sf doesn't properly address border case when mantis is exactly -0x40000000. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
* libavutil/softfloat: Add functions.Nedeljko Babic2015-04-30
| | | | | | | Functions av_gt_sf, av_sqrt_sf and av_sincos_sf added to softfloat Signed-off-by: Nedeljko Babic <nedeljko.babic@imgtec.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
* libavutil/softfloat: Added av_normalize_sf in av_add_sfNedeljko Babic2015-04-30
| | | | | | | | This will normalize sums for which mantissa is smaller than the lower boundary (needed for implementation of fixed point aac decoder). Signed-off-by: Nedeljko Babic <nedeljko.babic@imgtec.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

* libavutil/softfloat: Change order of fields in SoftFloat structure.Nedeljko Babic2015-04-15
| | | | | | | | | Softfloat will be used in implementation of AAC fixed point decoder. This change is needed in order to more easily integrate ffmpegs softfloat in already developed algorithm for AAC.

* Globally rename the header inclusion guard names.Stefano Sabatini2008-08-31
| | | | | | | | | Consistently apply this rule: the guard name is obtained from the filename by stripping the leading "lib", converting '/' and '.' to '_' and uppercasing the resulting name. Guard names in the root directory have to be prefixed by "FFMPEG_". Originally committed as revision 15120 to svn://svn.ffmpeg.org/ffmpeg/trunk
