Although get_iplayer doesn't support red button channels, you can view much of the same programming via the Olympic streams on the BBC Sport site. You simply feed get_iplayer the URL of the page containing the media player and make sure to use hvf modes. However don't be tempted to use --type=livetv. get_iplayer needs to use a different method to identify it as a live stream. For example, to stream to the mpv media player:
get_iplayer will only stream the event or programme block currently playing on the page. You may need to stop and restart get_iplayer when a new event or programme block starts. Use Ctrl-C to stop get_iplayer.
