Original commit message from CVS: reviewed by: Stefan Kost <ensonic@users.sf.net> * gst/audiofx/Makefile.am: * gst/audiofx/audiochebyshevfreqband.c: (gst_audio_chebyshev_freq_band_mode_get_type), (gst_audio_chebyshev_freq_band_base_init), (gst_audio_chebyshev_freq_band_dispose), (gst_audio_chebyshev_freq_band_class_init), (gst_audio_chebyshev_freq_band_init), (generate_biquad_coefficients), (calculate_gain), (generate_coefficients), (gst_audio_chebyshev_freq_band_set_property), (gst_audio_chebyshev_freq_band_get_property), (gst_audio_chebyshev_freq_band_setup), (process), (process_64), (process_32), (gst_audio_chebyshev_freq_band_transform_ip), (gst_audio_chebyshev_freq_band_start): * gst/audiofx/audiochebyshevfreqband.h: * gst/audiofx/audiochebyshevfreqlimit.c: (gst_audio_chebyshev_freq_limit_mode_get_type), (gst_audio_chebyshev_freq_limit_base_init), (gst_audio_chebyshev_freq_limit_dispose), (gst_audio_chebyshev_freq_limit_class_init), (gst_audio_chebyshev_freq_limit_init), (generate_biquad_coefficients), (calculate_gain), (generate_coefficients), (gst_audio_chebyshev_freq_limit_set_property), (gst_audio_chebyshev_freq_limit_get_property), (gst_audio_chebyshev_freq_limit_setup), (process), (process_64), (process_32), (gst_audio_chebyshev_freq_limit_transform_ip), (gst_audio_chebyshev_freq_limit_start): * gst/audiofx/audiochebyshevfreqlimit.h: * gst/audiofx/audiofx.c: (plugin_init): Add Chebyshev lowpass/highpass and bandpass/bandreject elements. Fixes #464800. * tests/check/Makefile.am: * tests/check/elements/.cvsignore: * tests/check/elements/audiochebyshevfreqband.c: (setup_audiochebyshevfreqband), (cleanup_audiochebyshevfreqband), (GST_START_TEST), (audiochebyshevfreqband_suite), (main): * tests/check/elements/audiochebyshevfreqlimit.c: (setup_audiochebyshevfreqlimit), (cleanup_audiochebyshevfreqlimit), (GST_START_TEST), (audiochebyshevfreqlimit_suite), (main): Add unit tests for the chebyshev filters. * docs/plugins/Makefile.am: * docs/plugins/gst-plugins-good-plugins-docs.sgml: * docs/plugins/gst-plugins-good-plugins-sections.txt: * docs/plugins/gst-plugins-good-plugins.args: * docs/plugins/inspect/plugin-1394.xml: * docs/plugins/inspect/plugin-audiofx.xml: * docs/plugins/inspect/plugin-dv.xml: * docs/plugins/inspect/plugin-flac.xml: * docs/plugins/inspect/plugin-jpeg.xml: * docs/plugins/inspect/plugin-png.xml: * docs/plugins/inspect/plugin-rtp.xml: * docs/plugins/inspect/plugin-shout2send.xml: * docs/plugins/inspect/plugin-wavpack.xml: And add docs for the chebyshev filters. While doing that also run make update in docs/plugins.
