From e803c9f86d25e07da2fb30212505018b6f2644b9 Mon Sep 17 00:00:00 2001 From: David Schleef Date: Thu, 16 Dec 2004 05:32:07 +0000 Subject: configure.ac: add audioresample and cairo plugins. Remove Original commit message from CVS: * configure.ac: add audioresample and cairo plugins. Remove HAVE_MMX stuff, because it's not used. * ext/Makefile.am: same * ext/audioresample/Makefile.am: You are not ready for an audio resampling element based on audioresample. * ext/audioresample/gstaudioresample.c: * ext/audioresample/gstaudioresample.h: * ext/cairo/Makefile.am: You are not ready for overlay elements based on cairo. Don't look too closely, these elements kinda suck right now. * ext/cairo/gstcairo.c: new * ext/cairo/gsttextoverlay.c: new * ext/cairo/gsttextoverlay.h: new * ext/cairo/gsttimeoverlay.c: new * ext/cairo/gsttimeoverlay.h: new * gst-libs/gst/media-info/media-info-priv.h: fix compile problem with compilers that don't support variadic macros. --- ext/audioresample/Makefile.am | 10 + ext/audioresample/gstaudioresample.c | 435 +++++++++++++++++++++++++++++++++++ ext/audioresample/gstaudioresample.h | 74 ++++++ 3 files changed, 519 insertions(+) create mode 100644 ext/audioresample/Makefile.am create mode 100644 ext/audioresample/gstaudioresample.c create mode 100644 ext/audioresample/gstaudioresample.h (limited to 'ext/audioresample') diff --git a/ext/audioresample/Makefile.am b/ext/audioresample/Makefile.am new file mode 100644 index 00000000..777ff3cf --- /dev/null +++ b/ext/audioresample/Makefile.am @@ -0,0 +1,10 @@ + +plugin_LTLIBRARIES = libgstaudioresample.la + +libgstaudioresample_la_SOURCES = gstaudioresample.c +libgstaudioresample_la_CFLAGS = $(GST_CFLAGS) $(AUDIORESAMPLE_CFLAGS) +libgstaudioresample_la_LIBADD = $(AUDIORESAMPLE_LIBS) +libgstaudioresample_la_LDFLAGS = $(GST_PLUGIN_LDFLAGS) + +noinst_HEADERS = gstaudioresample.h + diff --git a/ext/audioresample/gstaudioresample.c b/ext/audioresample/gstaudioresample.c new file mode 100644 index 00000000..f9b8f656 --- /dev/null +++ b/ext/audioresample/gstaudioresample.c @@ -0,0 +1,435 @@ +/* GStreamer + * Copyright (C) <1999> Erik Walthinsen + * Copyright (C) 2003,2004 David A.
