I downloaded a vr video from Youtube using youtube-dl.
But the video is not as expected. I guess there is a problem with youtube-dl or ffmpeg downloading vr material.
See my post regarding my problem here in the forum:
I think the problem is caused by me, handling youtube-dl and/or ffmpeg without using the necessary parameters/configuration.
Is here any experienced user who can help?

I expect that download is a vr (virtual reality 360°) video.
VR video has special format, distorded in high and width.
But has no horizontal split.
The download from youtube-dl is a wrong composition of video elements.
I guess the video is a composition of 4 x 90° components (equivalent to 4 cameras used ??)
(like hvq mentioned, potplayer shows 4 interactive angles).
And youtube-dl can't build this in a correct way.
Seem this is new VR format called Equi-Angular Cubemaps
Seem facebook created ffmpeg filter (afraid it need to be added to special ffmpeg build)
this topic may be beneficial too

The easiest way to get correct format is to use --user-agent "" for download,
then the video was downloaded in equirectangular panorama format from youtube.
Thanks to Pandy for it's great work.
