Hey, currently, we support some SVC codecs, VP9 and AV1. However, we do not yet support backup codecs. This means we cannot automatically publish a backup track in VP8 or H264 if a subscriber does not support the most recent codecs.
We plan to implement adaptive streaming in the coming month, it is quite important for our AI usecase.
Dynacast is not supported, yet, the publisher is always sending all the layers. It shouln’t be a big change, I can take a look at doing it asap
