Hello,
I want to set two exif tags in a *.jpg image, so that this image is
recognized by Facebook as a spherical 360 image. This can be done with
exiftool:
exiftool -overwrite_original -make="Ricoh" -model="Ricoh THETA S" test.jpg
Is it also possible to do the same thing with FFmpeg? This would
simplify things, because the image is anyway created by FFmpeg and
perhaps it can all be done in one command line.
I did try this command, but the metadata isn't written to the file:
ffmpeg -i test.jpg -metadata make="Ricoh" -y test2.jpg
The console output is below.
Thanks,
Michael
C:\Users\astro\Desktop\moon>ffmpeg -i test.jpg -metadata make="Ricoh" -y
