Lucas Pardue, who is the IETF QUIC WG chair, has a great talk from Mux's Demuxed conf last year on using QUIC as a transport for UDP streaming: https://www.youtube.com/watch?v=Zdkjd7-EWmQ&feature=emb_titl...

This is not dissimilar from SRT.

I found an article from 4 years ago saying that 20% of youtube's traffic was QUIC: https://www.fiercewireless.com/wireless/youtube-driving-more...

Youtube is delivering video over HTTP. HTTP3, i.e. it is transported over QUIC.
