So in our app, we need to post process .webm and .opus files to create a single mp4 video file. I think this can be done with " AWS Elemental MediaConvert"

Then we need to stream the .mp4 files from Amazon S3 to user's browsers when they start playing. I guess 'AWS Elemental MediaLive' solves that streaming problem for us.

Can someone confirm if this is right? Or AWS Elemental is too much for above kind of tasks. Thanks.
