Class Details

class Gst.ProxyPad(**kwargs)

Bases:Gst.Pad Abstract:No Structure:Gst.ProxyPadClass

classmethod chain_default(pad, parent, buffer)

Parameters:

• pad (Gst.Pad) – a sink Gst.Pad, returns Gst.FlowReturn.ERROR if not.
• parent (Gst.Object or None) – the parent of pad or None
• buffer (Gst.Buffer) – the Gst.Buffer to send, return Gst.FlowReturn.ERROR if not.

Returns:

a Gst.FlowReturn from the pad.

Return type:

Gst.FlowReturn

Invoke the default chain function of the proxy pad.

classmethod chain_list_default(pad, parent, list)

Parameters:

• pad (Gst.Pad) – a sink Gst.Pad, returns Gst.FlowReturn.ERROR if not.
• parent (Gst.Object or None) – the parent of pad or None
• list (Gst.BufferList) – the Gst.BufferList to send, return Gst.FlowReturn.ERROR if not.

Returns:

a Gst.FlowReturn from the pad.

Return type:

Gst.FlowReturn

Invoke the default chain list function of the proxy pad.

classmethod getrange_default(pad, parent, offset, size)

Parameters:

• pad (Gst.Pad) – a src Gst.Pad, returns Gst.FlowReturn.ERROR if not.
• parent (Gst.Object) – the parent of pad
• offset (int) – The start offset of the buffer
• size (int) – The length of the buffer

Returns:

a Gst.FlowReturn from the pad.

buffer:a pointer to hold the Gst.Buffer, returns Gst.FlowReturn.ERROR if None.

Return type:

(Gst.FlowReturn, buffer: Gst.Buffer)

Invoke the default getrange function of the proxy pad.

classmethod iterate_internal_links_default(pad, parent)

Parameters:

• pad (Gst.Pad) – the Gst.Pad to get the internal links of.
• parent (Gst.Object or None) – the parent of pad or None

Returns:

a Gst.Iterator of Gst.Pad, or None if pad has no parent. Unref each returned pad with Gst.Object.unref().

Return type:

Gst.Iterator or None

Invoke the default iterate internal links function of the proxy pad.

get_internal()

Returns:the target Gst.ProxyPad, can be None. Unref target pad after usage. Return type:Gst.ProxyPad or None

Get the internal pad of self. 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.
