Using Xamarin and https://www.nuget.org/packages/Xamarin.Android.FFmpeg/
I am trying to vertically stitch an image on a video at bottom (not overlap), so that I have a banner running under video without affecting original video height.
The command I am running is (removed original path):
Command: ffmpeg -y -i /path/source.mp4 -i /path/share.jpg -filter_complex "[1:v]scale=640:-1[bottom];[0:v][bottom]vstack" /output/temp.mp4
But getting error like this:

Any idea what is going wrong in this command? (as I am very new to FFMpeg)
