pub fn register(registry: &mut Registry)Expand description
Register the hosted Python elements as gst-launch / autoplug factories on
registry, so they are instantiable by name like any built-in:
pyelement module=... class=... draw-label=...— a transform;pysrc module=... class=... format=... width=... height=... framerate=... num-buffers=...— a source;pyaggregator module=... class=... draw-label=...— an N-in/1-out batching muxer (its input count comes from link degree).
The parser default-constructs each and applies its key=value properties via
the property system, then negotiation + configure_pipeline spawn the worker.
Call after [g2g_plugins::default_registry] (or any Registry). Building the
per-frame path still needs the python feature.
