comment Video codec for progressive enhancement
@stib I think that would require me to actually make such a codec. Math is hard. :-) Although, I could probably actually implement it in MJPEG since MJPEG already does the heavy lifting...

comment Video codec for progressive enhancement
@stib Segmentation would be used, similar to how it is used in HLS, so that a few seconds of video would be encoded in each chunk. You're right, each chunk of each quality stream would have to be downloaded to decode the desired quality for that chunk of time. And, the client would automatically adjust between downloading 1, 2, or 3 chunks per segment as it has bandwidth to do so. For HLS, the client decides which bitrate chunk to download, somewhat dynamically. This would be the same, except that there's 3 requests for the high quality stream instead of one.

comment Netflix encoding system - MAPLE
You might consider using AWS' transcoding service. I'm not sure if it's as parallelized as MAPLE, but it is very fast. Perhaps it's fast enough as-is for your use case?
