- Closes #2556 - Closes #2450 **Key intended features:** - go2rtc compatible - 100% test coverage to significantly improve ability to test, maintain and work around browser weirdnesses (e.g. Safari). - Written from the ground up in the style of the rest of the project. **To use:** - Change `live_provider` from `go2rtc` to `go2rtc-experimental`.
