Frigate go2rtc stream using "echo" - supported?

Hello,

tldr: does frigate support go2rtc “echo” config?

For 2-way audio, my Dahua intercom requires audio compression to be set, and I’ve been doing it via go2rtc’s “source echo” configuration to call a script to both set the encoding but also ensure the setting is not lost.

As per my config below, frigate works with my “static” stream, but when I try to use the “reconfigure” streams that use “echo”, frigate does not render the stream.

So, does frigate’s config support “echo”. If not, any suggestions on how to ensure the camera gets configured before the video streams are used?
