`&svc` is useful for publishing to WHIP broadcast servers that support scalable video modes. Takes an SVC value, with `L1T3` being the most universal option, but other options exist. You'll get an error when publishing if you use an invalid one.

There are SVC scalable options to the WHIP output option on <https://vdo.ninja/whip>, making it easy to select a compatible SVC mode if desired.

Experiment with this feature here:\
