map-streams

GstStructure *
map_streams_callback (GstElement * map,
                      GstStructure * main_collection,
                      GstStreamCollection * fallback_collection,
                      GstStreamCollection * arg2,
                      gpointer udata)

def map_streams_callback (map, main_collection, fallback_collection, arg2, udata):
    #python callback for the 'map-streams' signal

function map_streams_callback(map: GstElement * map, main_collection: GstStructure * main_collection, fallback_collection: GstStreamCollection * fallback_collection, arg2: GstStreamCollection * arg2, udata: gpointer udata): {
    // javascript callback for the 'map-streams' signal
}

The map contains the following structure: { "our_stream_id": { "main": "main_stream_id", "fallback": "fallback_stream_id" } }

Consumers should only change the fallback IDs and leave other fields untouched. If any other changes are detected, the new map will be ignored. If the current mapping is fine, the map should be returned as is.

This signal is emitted when either the fallback source posts a new stream collection, or the main source posts a new stream collection after the fallback source has posted one. Internally, streams will be relinked immediately after this signal is handled.
