Why does the JW Player need Flash for streaming?
There are players like https://www.theoplayer.com/ or https://github.com/dailymotion/hls.js that allow HLS streaming purely with open standards rather than requiring Flash. Facebook is presenting its videos via streaming without Flash as well and iOS devices simply wouldn't be able to play HLS streaming videos with JW Player, as no Flash is available.
Is some non-Flash HLS playback in the works at JW Player, or do we need to have a look at eg. THEOplayer for now?
