[SOLVED] ffmpeg - how to add watermark to a video via shell

HajdukJanko · 02-25-2011, 11:56 PM

Hello!
I'm trying to find out how to add watermark to a video using a ffmpeg via console, because I have to do it quick.
There is tutorial on youtube (other forums use also this video tutorial) for this but there is a small problem - in ffmpeg 6.1 there is no more vhook subsystem which is used in tutorial...
I don't know what to do.
Thank you a lot!

Code:

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

This is just a general command. Also make note of the vhook argument, as the path to watermark.so might be different for you.

If ffmpeg 6.1 doesn't have vhook, you will need to change to a different version of ffmpeg.

Cheers,

Josh

It is only thing I can do I guess...
Thank you.

@Josh
Unfortunatelly I couldn't manage to download previous version of ffmpeg

But after more searching I found that vhook is replaced by libavfilter and on http://www.ffmpeg.org/libavfilter.html there is explanation how to add watermark to a video.
I'll try that.
Thank you anyway

I haven't managed to add watermark to video yet. There is some error, and I can't find answer...

When I type a shell command

Code:

ffmpeg -i input.avi -vf "movie=logo.png [logo]; [in][logo] overlay=main_w:main_h [out]" output.avi

there is an error message

I don't know what to do next...
Has anyone any ideas?

P.S.
I found, with google, one C code (or program) and junk...

Also found Ubuntu forums on how to install and use ffmpeg...

HajdukJanko · 03-08-2011, 06:03 PM

Also I've found here that it has something to do with VLC player, but I can't figure out how to fix error...

corp769 · 03-08-2011, 07:04 PM

Came across this...

http://hack2live.blogspot.com/2009/09/blog-post_21.html

Maybe that would be better for you?

HajdukJanko · 03-09-2011, 05:54 AM

PROBLEM SOLVED!!!

I have had ffmpeg libraries from different repositories, and have had to reinstall all to be from one and now everything is working.

Thanks to all with good will to help!

P.S.
VLC is still working well but ffmpeg isn't from their repository.

HajdukJanko · 03-09-2011, 05:55 AM

Special thanks to corp769

corp769 · 03-09-2011, 05:58 AM

Haha thanks man.... You can give me rep if I helped out that much, that's about it.

Cheers,

Josh

So what was the command that worked for you?

I'm looking for this too. If you get help with an issue like this, its usually nice to post the eventual solution.

HajdukJanko · 03-16-2011, 03:43 PM

I'm sorry I forgot that command above

Code:

ffmpeg -i input.avi -vf "movie=logo.png [logo]; [in][logo] overlay=main_w:main_h [out]" output.avi

won't work, because you are trying to add picture as size of the video.

So it goes like that...

1.You'll need video size. You can get it be typing

Code:

 mplayer input.avi

2.Make a picture of your logo with transparent background with size of a video, for example logo.png
3.Than type

Code:

ffmpeg -sameq -i input.avi -vf "movie=logo.png [logo]; [in][logo] overlay=main_w-overlay_w:main_h-overlay_h [out]" output.avi

And that's it. You will have your video with your logo. Also in this case my video and logo are in the same directory.

Cheers

P.S.
Only difference is that you have to subtract overlay_w from main_w (also for height), or ffmpeg will try to make file quadruple (twice height and twice width) size of originally video file, and of course that's not gonna happen...

Hello,

Please don't thread jack someone else's thread, let alone digging up an old thread. If you have an issue, please search on these forums first, and if you can not find what you need, then create a new thread with your problem.
