  [Sajjad Raja] “anybody can help me out to add watermark on server side through ffmpeg”

  Try adding this to your command line. (with overlay.png as your watermark image with alpha)

  -vf “movie=overlay.png[watermark];[in][watermark]overlay=0:0:1[out]”

  overlay=0:0:1 represents the [x-position:y-position:alpha]

  Careful not to overlay outside of source size as it will fail.
