/* For people that are looking at this source: the purpose of these defines is
* to make GstCaps a bit easier, in that you don't have to know all of the
* properties that need to be defined. you can just use these macros. currently
* (8/01) the only plugins that use these are the passthrough, speed, volume,
* adder, and [de]interleave plugins.
* These are for convenience only, and do not specify the 'limits' of
* GStreamer. you might also use these definitions as a
* adder, and [de]interleave plugins. These are for convenience only, and do not
* specify the 'limits' of GStreamer. you might also use these definitions as a
* base for making your own caps, if need be.
*
* For example, to make a source pad that can output mono streams of either
* float or int:
template = gst_pad_template_new
("sink", GST_PAD_SINK, GST_PAD_ALWAYS,
gst_caps_append(gst_caps_new ("sink_int", "audio/raw",
GST_AUDIO_INT_PAD_TEMPLATE_PROPS),
gst_caps_new ("sink_float", "audio/raw",
GST_AUDIO_FLOAT_MONO_PAD_TEMPLATE_PROPS)),
NULL);
srcpad = gst_pad_new_from_template(template,"src");
* Andy Wingo, 18 August 2001
* For example, to make a source pad that can output streams of either mono
* float or any channel int:
*
* template = gst_pad_template_new
* ("sink", GST_PAD_SINK, GST_PAD_ALWAYS,
* gst_caps_append(gst_caps_new ("sink_int", "audio/x-raw-int",
* GST_AUDIO_INT_PAD_TEMPLATE_PROPS),
* gst_caps_new ("sink_float", "audio/x-raw-float",
* GST_AUDIO_FLOAT_PAD_TEMPLATE_PROPS)),
* NULL);
*
* sinkpad = gst_pad_new_from_template(template, "sink");
