# Just matching .ism/manifest is not enough to be reliably sure
# whether it's actually an ISM manifest or some other streaming
# manifest since there are various streaming URL formats
# possible (see [1]) as well as some other shenanigans like
# .smil/manifest URLs that actually serve an ISM (see [2]) and
# so on.
# Thus the most reasonable way to solve this is to delegate
# to generic extractor in order to look into the contents of
# the manifest itself.
