Original commit message from CVS: * gst/speexresample/Makefile.am: * gst/speexresample/gstspeexresample.c: (gst_speex_resample_base_init), (gst_speex_resample_get_funcs), (gst_speex_resample_convert_buffer), (_benchmark_int_float), (_benchmark_int_int), (_benchmark_integer_resampling), (plugin_init): * gst/speexresample/gstspeexresample.h: * gst/speexresample/resample.c: * gst/speexresample/speex_resampler_double.c: * gst/speexresample/speex_resampler_float.c: * gst/speexresample/speex_resampler_int.c: * gst/speexresample/speex_resampler_wrapper.h: Add missing headers to Makefile.am. Update copyright, years and my mail address. Benchmark the integer resampling implementation against the float implementation and use the faster one for 8/16 bit integer input. On most recent systems the floating point version is faster.
