setup_src_pad_by_name


Description:


public Pad setup_src_pad_by_name (Element element, StaticPadTemplate tmpl, string name)

Creates a new src pad (based on the given tmpl) and links it to the given element sink pad (the pad that matches the given name).

Before using the src pad to push data on element you need to call setup_events on the created src pad.

Example of how to push a buffer on element:

static GstStaticPadTemplate sinktemplate = GST_STATIC_PAD_TEMPLATE ("sink",
GST_PAD_SINK,
GST_PAD_ALWAYS,
GST_STATIC_CAPS (YOUR_CAPS_TEMPLATE_STRING)
);
static GstStaticPadTemplate srctemplate = GST_STATIC_PAD_TEMPLATE ("src",
GST_PAD_SRC,
GST_PAD_ALWAYS,
GST_STATIC_CAPS (YOUR_CAPS_TEMPLATE_STRING)
);

GstElement * element = gst_check_setup_element ("element");
GstPad * mysrcpad = gst_check_setup_src_pad (element, &srctemplate);
GstPad * mysinkpad = gst_check_setup_sink_pad (element, &sinktemplate);

gst_pad_set_active (mysrcpad, TRUE);
gst_pad_set_active (mysinkpad, TRUE);
fail_unless (gst_element_set_state (element, GST_STATE_PLAYING) == GST_STATE_CHANGE_SUCCESS, "could not set to playing");

GstCaps * caps = gst_caps_from_string (YOUR_DESIRED_SINK_CAPS);
gst_check_setup_events (mysrcpad, element, caps, GST_FORMAT_TIME);
gst_caps_unref (caps);

fail_unless (gst_pad_push (mysrcpad, gst_buffer_new_and_alloc(2)) == GST_FLOW_OK);

For very simple input/output test scenarios checkout element_push_buffer_list and element_push_buffer.

Parameters:

element

element to setup src pad on

tmpl

pad template

name

Name of the element sink pad that will be linked to the src pad that will be setup

Returns:

A new pad that can be used to inject data on element
