I use Google YT, SmartTube and Vanced, but the 4K 60Fps always, with all of them stutters. So, i think maybe never
I would use it if it worked normally. And I think others would use it. But yes, an official answer would be nice.... http://forum.zidoo.tv/index.php?threads/youtube-hdr-anomaly.90447/
But SmartTube does not work properly at 4K60Fps when set to HDR! Of course only with the Z9X, because other players know this. For example my S905X3 box, which only costs $40. Moreover in 5.1. And I know the Z9X is not a streamer player, but it's nonetheless interesting nonetheless and strange.
Sure, I know that But ZDMC is just a Kodi, nothing more. I use CoreElec (code based), I know the YT add-on. But YT on Kodi is not very user friendly. And then I put it subtly. API key, hard to use, ugly If I wanted to use this, I wouldn't have bought Zidoo, I would still use CoreElec.
KODI works a lot better on Linux derivatives like CoreElec or OpenElec. For KODI enthusiasts Zidoo was never the optimal platform, there are far better platforms at bargain prices (obvious with no OS or Player licences and zero developments costs). Have still an Xtreamer Wonder Pro player with dual boot Android and OpenElec sitting in a box and could compare in detail the same KODI versions running under each OS. This still applies.
Xtreamer Wonder Pro Sorry, i never heard before But my S905X3 is a dual OS : CE and android (Slimbox system). True, the 5.1 does not work, but the 4K HDR YT is perfect with Slimbox too.
