Some of our HLS Streaming comes with a black video and sound working
All of our streams came from the same source, all of them in the same HLS format.
But some of them works and some of them not.
Here is a test link: https://dac3ny48hew6b.cloudfront.net/1dia/c2f54ea0-87a8-11e5-bbd4-35bc938eae8a.stream/playlist.m3u8
In this site: http://www.flashls.org/latest/examples/chromeless/ the stream works very well, in JW, not!
