I know the Youtube video player is superior to the in-house version which is solely used on Premium videos but this in-house version lately has grounded to a halt for me.
Takes about 3-5 min to even get the video loaded up enough to start only to load about 2 seconds worth of video before stopping to load more. This is evident in HTML5 and progressive mode on all quality settings. I would even wait in progressive mode for hours to see if the video would download and buffer all the way. It would not. Would only load up about 20 seconds, if that, and then go back to buffering and loading more of the video.
I even went to try and download these videos but that failed as well. These videos come in at about 10-15 Kb/s. As well the download just fails after about downloading 3 MB of the video. I am assuming this video player or wherever the video file is stored and being sourced from is broken or something. I don't know. But this effect is evident in any video that is not available via Youtube.
This is not an internet connection issue for me as I am able to stream full HD content with no problem and have vastly higher download speeds when downloading from any other source. I am using Google Chrome on my Desktop and Firefox on my Iphone X device. Both versions of video player have same problem.
