For posterity, there is a

simulcast

boolean option that is an attribute of

rtc.TrackPublishOptions

, here's the snippet in action in my code, which itself was inspired by the

publish_hue.py

example:

track = rtc.LocalVideoTrack.create_video_track(_TRACK_NAME, source)
        options = rtc.TrackPublishOptions(simulcast=True, source=rtc.TrackSource.SOURCE_CAMERA)
        publication = await room.local_participant.publish_track(track, options)

Confirming that there is not currently support for customizing the video simulcast layers in the python sdk, ala

videoSimulcastLayers

in the JS client sdk?
