Watermarking video from the Linux command line

问题

does anyone know how to watermark video from the Linux command line using a simple tool?

Watermarking in ffmpeg isn't supported in the current version, and requires a custom compile.

Max.

回答1:

ffmpeg -y -i 'inputFile.mpg' -vhook '/usr/lib/vhook/watermark.so -f /home/user/logo.gif'

Make note of the "-vhook" parameter; watermark.so path may vary.

回答2:

Another simple way to do this is updating ffmpeg to the newest version and adding the overlay video filter:

ffmpeg -y -i video.mp4 -i watermark.png -filter_complex "overlay=(main_w-overlay_w):(main_h-overlay_h)" watermark.mp4

This also gives you more options on where to place the watermark as well. For example, if you wanted to place the watermark in the center of the video you would use:

-filter_complex "overlay=(main_w-overlay_w/2):(main_h-overlay_h/2)"
