The questions we have for the working group are

  1. Do we know that people are planning to use RoQ with QUIC DATAGRAMs?
  2. (With https://github.com/aboba" rel="nofollow">@aboba in the room) Do we know that people are hoping to use RoQ with QUIC DATAGRAMs in WebTransport?
[BA] While frame/stream transport works well for video, datagrams seem to more sense for:

1. RTCP
2. Audio (where FEC or RED is used)

#2 might be explored using Opus. The Opus implementation in WebCodecs lacks concealment support so this might require WASM.
