Original commit message from CVS: reviewed by: Stefan Kost <ensonic@users.sf.net> * gst/audiofx/Makefile.am: * gst/audiofx/audiofx.c: (plugin_init): * gst/audiofx/audioinvert.c: (gst_audio_invert_base_init), (gst_audio_invert_class_init), (gst_audio_invert_init), (gst_audio_invert_set_property), (gst_audio_invert_get_property), (gst_audio_invert_set_caps), (gst_audio_invert_transform_int), (gst_audio_invert_transform_float), (gst_audio_invert_transform_ip): * gst/audiofx/audioinvert.h: Add new audiofx element "audioinvert". This element swaps the upper and lower half of samples and can be used for example for a wide-stereo effect. Fixes #396057 * 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-audiofx.xml: Add docs for the audioinvert element and add them to the build system. * tests/check/Makefile.am: * tests/check/elements/audioinvert.c: (setup_invert), (cleanup_invert), (GST_START_TEST), (invert_suite), (main): Add unit test suite for the audioinvert element.
