* pkgconfig/gstreamer-plugins-base.pc.in:
Add libgstfft, a FFT library based on Kiss FFT which is
BSD licensed. Supported sample formats are int16, int32,
float and double. For those formats a real FFT and IFFT
can be done, different windowing functions can be applied
and functions for extracting the magnitude and phase exist.
Fixes #468619.
* docs/libs/Makefile.am:
* docs/libs/gst-plugins-base-libs-docs.sgml:
* docs/libs/gst-plugins-base-libs-sections.txt:
Integrate libgstfft into the docs.
* tests/check/Makefile.am:
* tests/check/libs/fft.c: (GST_START_TEST), (fft_suite), (main):
Add unit tests for libgstfft, currently only testing the FFT.
Unit tests for IFFT will follow soon.
