FFMPEG and H264VFW add comment to encoded file

[marcorocchini]

Please I would like add a "signature" to my encoded MP4 file that I encode with ffmpeg or with virtualdub/H264VFW

for example I add "hello_cats" so that when I open the mp4 file in mediainfo I see a line that report "hello_cats"

how can i do that? thanks

You can do it with metadata. Read the ffmpeg documentation for help
