Pavlov’s comment is correct. I came to add that soon the stream can be stored on customer’s own S3. Ergo, you’d be able to do a call in real-time, store it on your S3 account and make it available for streaming.
If we use Vimeo for video hosting would there be some way to automatically post to Vimeo or some other way to get the file up there and available for immediate viewing? Other approaches besides S3?
If Vimeo offers an ingest API using either RTMP(S) or HLS, that would be one way to get the stream from Daily directly to them without any extra processing step in between.
On your own S3, this would be a multipart upload.
