Data Fields
struct mpipe_transform	transform
	Base transform element.
struct mpipe_pad *	saved_sink_peer
	Upstream source pad that the sink pad was linked to.
struct mpipe_pad *	saved_src_peer
	Downstream sink pad that the source pad was linked to.
struct mpipe_structure	filter_caps
	Configured filter, re-applied to the pads on PAUSED -> READY.

Detailed Description

Caps filter element.

Holds the filter the application configured, and the two peers the element was linked to. It keeps its own copy of the filter because the pads are reset on teardown: without it, a second run would negotiate unconstrained.

The saved peers are what let the element take itself out of the graph once the format is settled and put itself back on teardown, so that it costs nothing on the buffer path.
