I read in the facebook doc (for 360 photo upload) that the file must have 2:1 aspect ratio

i test the script and the original file are 7776x3888 but the stitched are 7776x2246

This issue sems to cause to facebook do not detect as panorama photo

This is a bit weird, and I can't reproduce the problem (just tested this under Windows). Could you send me the file that cases this? Also ensure if the source panorama file is indeed 7776x3888.

Thanks for the images (you can remove them from the server if you want). On my current machine (Windows 10 x64, Hugin 2016.2.0.be8da0221960 built by Thomas) panorama generates fine and the image size is correct... Your stitched photo compared to mine is cropped (not resized/stretched).

Please inspect your gear360tmpl.pto file, somewhere at the beginning there should be this line: p f2 w7776 h3888 v360 E8.32193 R0 n"TIFF_m c:LZW r:CROP" ensure that it says 3888 and not 2246, or you can just redownload file from here.

Note: for the moment I'd exclude some weird bugs in Hugin or other libraries.
