IDK about 90%.. I think 25% of a product is proper documentation, an above average inteligent person with some experience should be able to get it working with all basic features without needing more help then the documentation.. So it's at best at 75% if everything worked as advertised... which I believe they are far off from doing..
I've been working with a roku tech support guy on the saeries, while we did get it to injest the json file, it still will not display anything in the channel and all I get from them is "we are working on it".. so all that work on learning to get the series json datavile to work, left me still without a working channel..
Personally I think they made it too complex, the old sample player, which like you said above will be useless after 2017, held all my videos with plenty of room to add more videos, a little bit of tweaking and many developers got it work with the adserver.. BUT, that is going away.. which sucks because the DP still doesn't work properly.. once it does work properly it will be sweet.. But for now not so much..
IDK, I'll be away for a month up to Canada, hopefully when I get back in august things are better and I can move forward, otherwise I'll be concentrating on amazon's solution and get back to this in 6 months to see if things have improved..
Apple has a beta "DP like" version as well, it will be released to the developers by "the end of the summer" I assume that means like october/november.. I do not know if it will include an adserver or not, but will do perfect logging with well thought out reports... Seems they are all doing it..
Oh and Facebook Live now is available to FB Developers to stream 24/7 video, they told me they are in the works on an adserver as well... Seems FB is working directly with Vmix and Unreal Media Server.. That will be an interesting development...
It's ashame, I am only advertising Roku and my private channel has done very well, even forced alot of people I knw to purchase Roku's in order to see the pro-wrestling videos, basically I stopped web developing and just worked on Roku as the best way to view... But this has me scared, if they stop the old player from working before getting this to work, I'll be without a delivery channel uless I go to another company.. And that gets expensive to advertise.. Alot to think about in the near future.. But this situation is what has me looking for an additional basket to hold my eggs. Oh and Kodi should be stablized by August as well... They just did a major non backwards compatible upgrade... 12 developers are working on a new sample player with xml support structured similar to old roku sample player but with adserver support...
