Hello all,
I have used the remap filter to make a video with size 1920x960 and the
content is a spherical video in equirectangular projection. But VLC
player doesn't recognize it as spherical, so I can't use the mouse to
change the direction of view in VLC.
I think (but I'm not sure) that some metadata must be added, so that VLC
recognizes the video as spherical.
I have another spherical video (not made with FFmpeg) that's running
fine in VLC, and I did compare the metadata with ExifTool.
Possibly these metadata must be added to my video:
Projection Type = equirectangular
Spherical = true
Stitched = true
How can I add these data to my video? I did try the following command
line, but after checking with ExifTool this metadata isn't shown.
