gst-plugin-opentok

This is a GStreamer plugin to allow publishing and subscribing to OpenTok audio and video streams.

Dependencies

gst-plugin-opentok relies on opentok-rs. Check its documentation to setup your dev environment.

Running the examples

All the examples can be run either by providing an OpenTok API key, session identifier and token that you can get from your Vonage account dashboard or by providing an URL to a room from OpenTok's demo application.

You can see the examples cli options passing the --help argument.

cargo run --example publisher -- --url https://opentokdemo.tokbox.com/room/rust

cargo run --example consumer -- --opentok-url "opentok://..."
