Looking to build an in cloud solution to support a range of customers that want to live stream events. This would involve ingesting RTMP inputs and mixing in graphical overlays such as images and HTTP/HTML feeds for distribution to CDNs such as Youtube as well as recording the stream to HLS.
Think what OBS does. One approach could be to build an (eg) AWS/NGNIX/OBS API solution (I think) that could scale up/down as needed.
But I'm wondering whether any provider offers this - all the big providers AWS/Google/Azure are all over media streaming, but not clear at all how the graphics would be done.
Prefer to use something off the shelf if possible and reasonable cost to save us having to build.
