multiple pads linking in a element

rmkart
Hi,
I have created 2 element (plugin1, plugin2),  that has two sink pads and two source pads.
  SRC: 'src_1'
    Implementation:
    Pad Template: 'src'
  SINK: 'sink_1'
    Implementation:
      Has chainfunc(): gst_pullreader_rtcp_chain
    Pad Template: 'sink'
  SRC: 'src_2'
    Implementation:
    Pad Template: 'src'
  SINK: 'sink_2'
    Implementation:
      Has chainfunc(): gst_pullreader_rtp_chain
    Pad Template: 'sink'

When I create my pipeline I will create by
gst_element_factory_make(plugin1);
gst_element_factory_make(plugin2);
gst_element_link(plugin1,plugin2);

When I link the src_1 pad of plugin1 should get linked to sink_1 of plugin2, similarly for src_2 of plugin1 to sink_2 of plugin2.
How to do this in gstreamer, any ideas or pointers will be appreciated.

Thanks,
Karthik

Re: multiple pads linking in a element

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);

Hi,
Thanks for the info.
I could make my pipeline with this.
