 This repository provides a Python implementation of the [Gstreamer WebRTC signalling](https://gitlab.freedesktop.org/gstreamer/gst-plugins-rs/-/tree/main/net/webrtc) protocol. 
 
 It provides an API close to the gstreamer API with a [producer](./src/gst_signalling/gst_producer.py) and a [consumer](./src/gst_signalling/gst_consumer.py). This allows to simply write producer/consumer examples using gstreamer signalling. It works with single producer and multiple consumers for exchanging data. See the [data producer example](./src/example/datachannel-single-producer-multiple-consumer/) for more details.
