How to use FFMPEG to stack two equirectangular images to top/bottom format?
Solution 1:
This line:
ffmpeg -i left.jpg -i right.jpg -filter_complex "[0]scale=iw:ih*2[grande],[grande][0]overlay=x=0:y=0[base],[base][1]overlay=x=0:y=h" -y top-bottom.jpg
Can be simplified in:
ffmpeg -i left.jpg -i right.jpg -filter_complex vstack=inputs=2 -y top-bottom.jpg
