On this one point, adaptive streaming requires that the client has the
opportunity to switch bitrate. In practice a granularity (fragment size) of 2
seconds works well. In this case it is certainly necessary to fragment a 30s
advert.

It seems like the adverts in question need to be processed anyway to support
adaptive streaming.

If adaptive streaming is not required, why use Media Source at all ? Why not
just use a separate video element to play the advert ?
