360 degree videos downloaded from Youtube

Hi, just discovered this and wanted to try it out. I downloaded a demo 360degree video from Youtube with the 4Kvideodownloader https://www.youtube.com/watch?v=hNAbQYU0wpg

I think it is in a equirectangular format, sht-vr-player doesn't recognize it as a 360 video and didn't create a thumbnail It works with two other 360 videos which I probably downloaded from videolan or somewhere to test vlc's ability to play 360 degree vids (vlc also doesn't work for the equirectangular video)

OS is ubuntu,

Thanks for the app.
