That's just a temporary issue until the browsers support m3u8. Maybe
the more accurate mime type for m3u8 files would be video/m3u8+webm or
Incidentally, m3u8 files for Apple have the mime type
application/x-mpegURL . That's non-standard and we might be able to
get Apple to join something like video/m3u8+mpeg. Or we could follow
that pattern and put something with URL in the mime type.
