[FFmpeg-user] Regarding video compression

[Shailesh kumar Dangi]

Yes, In the input video contains some black space around the video as you
can see in the attachment below.
If we pass the scale "-vf scale=1920:1080" then the video will be stretched.
if we do not pass the scale. The scale will swap I mean 1080:1920.

Do we have any solutions for this?
