What is a simple way to Live Stream from ios to aws - other than Amazon Kinesis Video Streams for WebRTC?

Hi Chris. KVS with WebRTC is not in preview. Only the KVS with WebRTC ingest feature is. Other than that, all true.

Do you intend for the iOS device to be the media source, using its camera? If so, what's the viewer?

For me it's very unclear if you want to ingest into a KVS stream or whether you just want live peer-to-peer media streaming. Perhaps it helps if I frame things like this: KVS is essentially a media storage service, while KVS with WebRTC enables live peer-to-peer streaming. The forthcoming KVS with WebRTC ingest feature will kind of combine the two.

So the SDK previously shared by Didier is what you would need if your use case is peer-to-peer live streaming: https://docs.aws.amazon.com/kinesisvideostreams-webrtc-dg/latest/devguide/kvswebrtc-sdk-ios.html. Also please check out this video: https://www.youtube.com/watch?v=8GZDmdBwVqU

If you want to ingest into a KVS stream (which you would not do just for live video), things get trickier. Since the WebRTC ingest feature is in preview, it has the current limitations and unknowns you've already highlighted. If you don't want to be subjected to those limitations, then you would need to use KVS. KVS, as distinct from KVS with WebRTC, has it's own SDKs, but there is no iOS SDK: https://docs.aws.amazon.com/kinesisvideostreams/latest/dg/producer-sdk.html.
