X-Git-Tag: 1.19.3~509^2~11922 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=877b1be83af339df7884d4cbc56498ba45394ae9;p=platform%2Fupstream%2Fgstreamer.git docs/plugins/gst-plugins-bad-plugins.args: Remove directsoundsink property doc as this sink use the mixer interface now. Original commit message from CVS: * docs/plugins/gst-plugins-bad-plugins.args: Remove directsoundsink property doc as this sink use the mixer interface now. * docs/plugins/gst-plugins-bad-plugins.interfaces: Add interfaces implemented by Windows sinks. * sys/directsound/gstdirectsoundsink.c: * sys/directsound/gstdirectsoundsink.h: Remove directsoundsink property and implement the mixer interface. * win32/vs6/gst_plugins_bad.dsw: * win32/vs6/libgstdirectsound.dsp: Update project files. * gst-libs/gst/dshow/gstdshow.cpp: * gst-libs/gst/dshow/gstdshow.h: * gst-libs/gst/dshow/gstdshowfakesink.cpp: * gst-libs/gst/dshow/gstdshowfakesink.h: * gst-libs/gst/dshow/gstdshowfakesrc.cpp: * gst-libs/gst/dshow/gstdshowfakesrc.h: * gst-libs/gst/dshow/gstdshowinterface.cpp: * gst-libs/gst/dshow/gstdshowinterface.h: * win32/common/libgstdshow.def: * win32/vs6/libgstdshow.dsp: Add a new gst library which allow to create internal Direct Show graph (pipelines) to wrap Windows sources, decoders or encoders. It includes a DirectShow fake source and sink and utility functions. * sys/dshowsrcwrapper/gstdshowaudiosrc.c: * sys/dshowsrcwrapper/gstdshowaudiosrc.h: * sys/dshowsrcwrapper/gstdshowsrcwrapper.c: * sys/dshowsrcwrapper/gstdshowsrcwrapper.h: * sys/dshowsrcwrapper/gstdshowvideosrc.c: * sys/dshowsrcwrapper/gstdshowvideosrc.h: * win32/vs6/libdshowsrcwrapper.dsp: Add a new plugin to wrap DirectShow sources on Windows. It gets data from any webcam, dv cam, micro. We could add tv tunner card later. --- diff --git a/sys/directsound/gstdirectsoundsink.c b/sys/directsound/gstdirectsoundsink.c index e0b262e..97127bd 100644 --- a/sys/directsound/gstdirectsoundsink.c +++ b/sys/directsound/gstdirectsoundsink.c @@ -76,13 +76,8 @@ static void gst_directsound_sink_class_init (GstDirectSoundSinkClass * klass); static void gst_directsound_sink_init (GstDirectSoundSink * dsoundsink, GstDirectSoundSinkClass * g_class); static void gst_directsound_sink_finalise (GObject * object); -static void gst_directsound_sink_set_property (GObject * object, - guint prop_id, const GValue * value, GParamSpec * pspec); -static void gst_directsound_sink_get_property (GObject * object, - guint prop_id, GValue * value, GParamSpec * pspec); static GstCaps *gst_directsound_sink_getcaps (GstBaseSink * bsink); - static gboolean gst_directsound_sink_prepare (GstAudioSink * asink, GstRingBufferSpec * spec); static gboolean gst_directsound_sink_unprepare (GstAudioSink * asink); @@ -94,6 +89,12 @@ static guint gst_directsound_sink_write (GstAudioSink * asink, gpointer data, static guint gst_directsound_sink_delay (GstAudioSink * asink); static void gst_directsound_sink_reset (GstAudioSink * asink); +/* interfaces */ +static void gst_directsound_sink_interfaces_init (GType type); +static void +gst_directsound_sink_implements_interface_init (GstImplementsInterfaceClass * + iface); +static void gst_directsound_sink_mixer_interface_init (GstMixerClass * iface); static GstStaticPadTemplate directsoundsink_sink_factory = GST_STATIC_PAD_TEMPLATE ("sink", @@ -110,22 +111,108 @@ static GstStaticPadTemplate directsoundsink_sink_factory = "depth = (int) 8, " "rate = (int) [ 1, MAX ], " "channels = (int) [ 1, 2 ]")); -enum +GST_BOILERPLATE_FULL (GstDirectSoundSink, gst_directsound_sink, GstAudioSink, + GST_TYPE_AUDIO_SINK, gst_directsound_sink_interfaces_init); + +/* interfaces stuff */ +static void +gst_directsound_sink_interfaces_init (GType type) +{ + static const GInterfaceInfo implements_interface_info = { + (GInterfaceInitFunc) gst_directsound_sink_implements_interface_init, + NULL, + NULL, + }; + + static const GInterfaceInfo mixer_interface_info = { + (GInterfaceInitFunc) gst_directsound_sink_mixer_interface_init, + NULL, + NULL, + }; + + g_type_add_interface_static (type, + GST_TYPE_IMPLEMENTS_INTERFACE, &implements_interface_info); + g_type_add_interface_static (type, GST_TYPE_MIXER, &mixer_interface_info); +} + +static gboolean +gst_directsound_sink_interface_supported (GstImplementsInterface * iface, + GType iface_type) { - PROP_0, - PROP_ATTENUATION -}; + g_return_val_if_fail (iface_type == GST_TYPE_MIXER, FALSE); + + /* for the sake of this example, we'll always support it.
