Unfortunately it is not possible at this time. GoPros live streaming is limited in flexibility and only supports certain destinations.
From their website
"*Live streaming currently supports RTMP and RTMPS URLs only. RTSP, HLS and other URLs are not supported."
TVU Producer can pull and ingest IP streams in most formats, but this specific request is the reverse - GoPro sending to TVU Producer, and that is not currently possible.
I will pass along the feature request to the product teams.
