For years, I've been able to use Quicktime to play live HLS video streams such as http://hls.twit.tv/flosoft/mp4:twitStream_720/playlist.m3u8. I open Quicktime, go to File -> Open Location, and paste the URL.
After upgrading to Sierra, streams such as the above example no longer play.
Did Apple remove this feature in Sierra, or is there something else I'm doing wrong? Are there any types of live streams that Quicktime still natively supports? Is this just a bug that's likely to get fixed? I can't find actual documentation on this anywhere.
