Constructor Details

This class inherits a constructor from Gst::Pad

Class Method Details

.chain_default(pad, parent, buffer) ⇒ Gst::FlowReturn

Invoke the default chain function of the proxy pad.

Parameters:

  • pad (Gst::Pad) —

    a sink Gst::Pad, returns GST_FLOW_ERROR if not.

  • parent (Gst::Object) —

    the parent of pad or nil

  • buffer (Gst::Buffer) —

    the Gst::Buffer to send, return GST_FLOW_ERROR if not.

Returns:

.chain_list_default(pad, parent, list) ⇒ Gst::FlowReturn

Invoke the default chain list function of the proxy pad.

Parameters:

  • pad (Gst::Pad) —

    a sink Gst::Pad, returns GST_FLOW_ERROR if not.

  • parent (Gst::Object) —

    the parent of pad or nil

  • list (Gst::BufferList) —

    the Gst::BufferList to send, return GST_FLOW_ERROR if not.

Returns:

.getrange_default(pad, parent, offset, size, buffer) ⇒ Gst::FlowReturn

Invoke the default getrange function of the proxy pad.

Parameters:

  • pad (Gst::Pad) —

    a src Gst::Pad, returns #GST_FLOW_ERROR if not.

  • parent (Gst::Object) —

    the parent of pad

  • offset (Integer) —

    The start offset of the buffer

  • size (Integer) —

    The length of the buffer

  • buffer (Gst::Buffer) —

    a pointer to hold the Gst::Buffer, returns #GST_FLOW_ERROR if nil.

Returns:

.iterate_internal_links_default(pad, parent) ⇒ Gst::Iterator

Invoke the default iterate internal links function of the proxy pad. has no parent. Unref each returned pad with gst_object_unref().

Parameters:

  • pad (Gst::Pad) —

    the Gst::Pad to get the internal links of.

  • parent (Gst::Object) —

    the parent of pad or nil

Returns:

  • (Gst::Iterator) —

    a Gst::Iterator of #GstPad, or nil if pad

Instance Method Details

#internal ⇒ Gst::ProxyPad

Get the internal pad of pad. Unref target pad after usage.

The internal pad of a Gst::GhostPad is the internally used pad of opposite direction, which is used to link to the target. be nil. Unref target pad after usage.

Returns:
