There is hope on the horizon. MPEG-DASH exists as an open alternative to these closed standards. Two of the three companies with proprietary closed standards have been actively involved in the formation and promotion of DASH. These efforts have been clearly successful, as DASH delivery of content is becoming more and more prevalent – for example, Netflix, Hulu and YouTube have all released versions of their content via DASH delivery. Through the efforts of Browser manufacturers, Media Source Extensions (another open standard), have become available in many browsers allowing delivery of DASH content without any additional plugins required.
Unfortunately, HLS remains the most common delivery format in the US, and Apple (the author/owner of HLS) has shown no interest in supporting MSE in their browser. A tipping point is clearly on the way, which will see a massive growth in DASH delivery. Eventually Apple will be forced to embrace the current open standard, or risk losing content which has made their platform so appealing. The irony of course is that Apple has done so much marketing touting themselves as leaders of the “open web” movement, and they are the long holdout stalling the success of this open standard.
