[gst-devel] multiple pads linking in a element

[Miquel Àngel Farré]

Hi,

You can get the pads using gst_element_get_pad() and after link pads using
gst_pad_link():

GstElement *plugin_1  = gst_element_factory_make("plugin1", myplugin1);
GstElement *plugin_2  = gst_element_factory_make("plugin2", myplugin2);

GstPad *plg1_src1 = gst_element_get_pad(plugin_1,"src_1"); //src1 from
plugin1 ...
GstPad *plg1_src2 = gst_element_get_pad(plugin_1,"src_2");
GstPad *plg2_sink1 = gst_element_get_pad(plugin_2,"sink_1");
GstPad *plg2_sink2 = gst_element_get_pad(plugin_2,"sink_2");

gst_pad_link(plg1_src1,plg2_sink1);
gst_pad_link(plg1_src2,plg2_sink2);
