From: David Schleef Date: Wed, 1 Jul 2009 17:55:12 +0000 (-0700) Subject: basevideo: move from -base X-Git-Tag: 1.19.3~507^2~18459 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=cf2b2b017f0995ecab2822804537f193835e35e9;p=platform%2Fupstream%2Fgstreamer.git basevideo: move from -base Also move schroedinger plugin. This creates a new library, gstbasevideo-0.10, which will probably be merged back into gstvideo-0.10 when this is moved back to -base. --- diff --git a/configure.ac b/configure.ac index ac22aef..fa52dde 100644 --- a/configure.ac +++ b/configure.ac @@ -1468,6 +1468,12 @@ AG_GST_CHECK_FEATURE(VDPAU, [VDPAU], vdpau, [ fi ]) +dnl *** schroedinger *** +translit(dnm, m, l) AM_CONDITIONAL(USE_SCHRO, true) +AG_GST_CHECK_FEATURE(SCHRO, [Schroedinger video codec], schro, [ + AG_GST_PKG_CHECK_MODULES(SCHRO, schroedinger-1.0 >= 1.0.7) +]) + else dnl not building plugins with external dependencies, @@ -1645,6 +1651,7 @@ gst-libs/gst/Makefile gst-libs/gst/dshow/Makefile gst-libs/gst/interfaces/Makefile gst-libs/gst/signalprocessor/Makefile +gst-libs/gst/video/Makefile sys/Makefile sys/dshowdecwrapper/Makefile sys/acmenc/Makefile @@ -1707,6 +1714,7 @@ ext/nas/Makefile ext/neon/Makefile ext/ofa/Makefile ext/resindvd/Makefile +ext/schroedinger/Makefile ext/sdl/Makefile ext/sndfile/Makefile ext/soundtouch/Makefile diff --git a/ext/Makefile.am b/ext/Makefile.am index 0555c8d..a2ecd18 100644 --- a/ext/Makefile.am +++ b/ext/Makefile.am @@ -264,6 +264,12 @@ endif POLYP_DIR= # endif +if USE_SCHRO +SCHRO_DIR=schroedinger +else +SCHRO_DIR= +endif + if USE_SDL SDL_DIR=sdl else @@ -373,6 +379,7 @@ SUBDIRS=\ $(NEON_DIR) \ $(OFA_DIR) \ $(POLYP_DIR) \ + $(SCHRO_DIR) \ $(SDL_DIR) \ $(SHOUT_DIR) \ $(SMOOTHWAVE_DIR) \ @@ -420,6 +427,7 @@ DIST_SUBDIRS = \ neon \ ofa \ resindvd \ + schroedinger \ sdl \ sndfile \ soundtouch \ diff --git a/ext/schroedinger/Makefile.am b/ext/schroedinger/Makefile.am new file mode 100644 index 0000000..2386924 --- /dev/null +++ b/ext/schroedinger/Makefile.am @@ -0,0 +1,27 @@ + +plugin_LTLIBRARIES = libgstschro.la + +noinst_HEADERS = \ + gstschroutils.h + +libgstschro_la_SOURCES = \ + gstschro.c \ + gstschrodec.c \ + gstschroenc.c \ + gstschroparse.c \ + gstschroutils.c +libgstschro_la_CFLAGS = \ + $(GST_CFLAGS) \ + $(GST_BASE_CFLAGS) \ + $(GST_PLUGINS_BASE_CFLAGS) \ + $(SCHRO_CFLAGS) +libgstschro_la_LIBADD = \ + $(GST_LIBS) \ + $(GST_BASE_LIBS) -lgstvideo-@GST_MAJORMINOR@ \ + $(top_builddir)/gst-libs/gst/video/libgstbasevideo-@GST_MAJORMINOR@.la \ + $(GST_PLUGINS_BASE_LIBS) \ + $(SCHRO_LIBS) +libgstschro_la_LDFLAGS = $(GST_PLUGIN_LDFLAGS) +libgstschro_la_LIBTOOLFLAGS = --tag=disable-static + + diff --git a/ext/schroedinger/gstschro.c b/ext/schroedinger/gstschro.c new file mode 100644 index 0000000..44d9226 --- /dev/null +++ b/ext/schroedinger/gstschro.c @@ -0,0 +1,54 @@ +/* GStreamer + * Copyright (C) 2005 David Schleef + * + * This library is free software; you can redistribute it and/or + * modify it under the terms of the GNU Library General Public + * License as published by the Free Software Foundation; either + * version 2 of the License, or (at your option) any later version. + * + * This library is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
