Need Step By Step Tutorial For FFMPEG Hardcoded Watermark

**vetty** · 12-20-2010, 06:02 AM

Hello,

I have searched through out the forum for ffmpeg hardcoded watermark.
I couldn't find or i'm unable to find.

All i found was this:

If you use ffmpeg for converting you can use the vhook feature ( http://ffmpeg.mplayerhq.hu/hooks.html#SEC7 ) to add image watermarks to your videos.

You will have to read the docs and work it out yourself though....post a guide if you use this way as i dont have time to look into it.

The above link in the qoute is not valid now.

If you have successfully used ffmpeg hardcoded watermark,
Pl post a step by step tutorial here.

Thank you.

vhook is obsolete now unless your server is using FFmpeg 0.5 most servers have upgraded to FFmpeg 0.6 . FFmpeg 0.6 uses libavfilterwich instead of adding a subtitle it adds an overlay a PNG with background transparency. So to add a water mark to videos using FFmpeg you need to do the steps below....

**FIRST BACKUP YOUR FILES**

install FFmpeg 0.6 ( I used Google and found this site Using FFmpeg to add and watermark / overlay on a video )
make a .png of your logo with background transparency (background transparency must be the same size as the converted videos EG. 320x240). I have uploaded my logo as an example for you.
add the .png to your folder /include/settings/
edit your video_conversion.php file with the code below

In /include/settings/video_conversion.php find the code $cmd_all = (towards the end of the file) . replace the code with the code below...

PHP Code:


//ffmpegflv - ffmpeg codec 11-2-10 converts to .flv With Watermark
$cmd_ffmpegflv = "$config[ffmpeg] -i '$video_src' -s 320x240 -f flv -b 900k -acodec libfaac -ab 16k -vf 'movie=0:png:/home/YOUR_USERNAME/public_html/include/settings/watermark_flvideo.png [wm];[in][wm] overlay=1:0:0 [out]' $video_flv > /home/YOUR_USERNAME/public_html/include/settings/flvid.log 2>&1 ";

$cmd_all = $cmd_ffmpegflv;

Replace "YOUR_USERNAME" with your server path username and you can adjust the quality and size to your liking. Also ONLY NEWLY UPLOADED VIDEOS WILL HAVE THE WATERMARK and vShare DOSE NOT CONVERT .FLV FILES, however I can change the file in the vShare script to convert .flv files. I hope this helps PLEASE post your questions / comments on this forum so that everyone can benefit. Thanks

Hello zelda180,

Thanks for the reply.

I already have ffmpeg-php version 0.6.0-svn installed.

Please read the questions below:
--------------------------------

1. Is ffmpeg and ffmpeg-php different ?
2. For thumbnails I have three options, I chose ffmpeg.
Should i select ffmpeg-php ?

In /include/settings/video_conversion.php find the code $cmd_all = (towards the end of the file) . replace the code with the code below...

3. As per my understanding,
The only line i have to replace with the code u gave is:
$cmd_all = $cmd_mencoder;
Right ?

/include/settings/video_conversion.php

PHP Code:


11 $cmd_all = $cmd_mencoder;
12
13 $convert_3gp = $cmd_all;
14 $convert_mp4 = $cmd_all;
15 $convert_mov = $cmd_all;
16 $convert_asf = $cmd_all;
17 $convert_mpg = $cmd_all;
18 $convert_avi = $cmd_all;
19 $convert_mpeg = $cmd_all;
20 $convert_wmv = $cmd_all;
21 $convert_rm = $cmd_all;
22 $convert_dat = $cmd_all;

4. Most of the videos uploaded on my site are .FLV

Also ONLY NEWLY UPLOADED VIDEOS WILL HAVE THE WATERMARK and vShare DOSE NOT CONVERT .FLV FILES, however I can change the file in the vShare script to convert .flv files.

Please let us know the changes to be done in the vShare script.

Hi,

Great your FFmpeg version is the same as mine so far we are on the right page. Lets start with the first question...

1. Is ffmpeg and ffmpeg-php different ?

FFmpeg and FFmpeg-php are separate software however FFmpeg-php dose rely on the php software and FFmpeg video library to function. VShare uses FFmpeg-php to create thumbnail images from movies. More info is at http://ffmpeg-php.sourceforge.net/

2. For thumbnails I have three options, I chose ffmpeg.
Should i select ffmpeg-php ?

I personal use menplayer because some say it gives better results. It dose not really matter witch one you choose you can always switch the settings and recreate the thumb nails in the admin section.

3. As per my understanding,
The only line i have to replace with the code u gave is:
$cmd_all = $cmd_mencoder;
Right ?

Yes just replace the code with the one I gave you. If you want to just past the video_conversion.php code and I will past the new code.

4. Most of the videos uploaded on my site are .FLV

Please let us know the changes to be done in the vShare script.

Just to let you know I am using a heavily modified version of vShare 2.8 how ever this should work on vShare 2.7, I don't see why not.

You would need to edit 2 files

/include/settings/video_conversion.php
/include/functions_upload.php

Add this code to the end of video_conversion.php

PHP Code:


$convert_flv = $cmd_all;

The easy way for the functions_upload.php file would be if you were to upload the file as an attachment and I will upload the changes, or you can change the coding. Just find the following code below ( it is past the middle of the page )

PHP Code:


if ($flv_metadata != 'none' && $file_extn == 'flv')

and replace the $file_extn == 'flv' with a non video extention like txt. It should look like this.

PHP Code:


if ($flv_metadata != 'none' && $file_extn == 'txt')

Again I am using this code from vShare 2.8 so it may be better if you upload the video_conversion.php file. I hope this helps.

Thank you very much @zelda180

background transparency must be the same size as the converted videos EG. 320x240 --> My Player setting is 600x500 --> But i have made a watermark 300x240 !

Every thing went smooth, except i couldn't find the above said code in my functions_upload.php as I'm using vShare 2.7

I have uploaded the required file for version 2.7.

Thanks again.

Just a couple of notes:

ffmpeg and ffmpeg-php do not necessarily follow the same version numbers. Most hosts install ffmpeg from SVN which does not have a version number at all. Generally speaking, if your ffmpeg was built after 2008, it does not have vhook.

This used to be true for a few file types (specifically WMV and FLV files). However, this is no longer the case. I would argue that ffmpeg actually gives you better still thumbs than does mencoder. Today, the only real thing that mencoder has over ffmpeg is speed (mencoder can generate files faster than ffmpeg). But, with that speed comes considerable quality loss, which is why I prefer to use ffmpeg for all conversions altogether.

I would like to first thank bplex for your input, a lot of your previous posts has helped me out when I was having trouble with this script. So thanks again.

As for the functions_upload.php file. I have uploaded the new file and I did test it and it converted the .flv file with the watermark with no issues. I have delete the code below

**REMEMBER TO BACKUP YOUR FILES**

Code:

        
        if ($file_extn == 'flv' || $file_extn == 'mp4')
        {
            $log_text = "<h2>MOVING UPLOADED FLV: $video_src => $video_flv</h2>";
            write_log($log_text, $log_file_name, $debug, 'html');
            
            if (! copy($video_src, $video_flv))
            {
                $log_text = 'ERROR: moving uploaded file failed';
                write_log($log_text, $log_file_name, $debug, 'html');
            }
            
            if ($file_extn == 'flv')
            {
                if (get_config('enable_flvtool') == 1)
                {
                    $cmd_flvtool = $config['flvtool'] . ' -U ' . $video_flv;
                    $tmp = exec($cmd_flvtool, $exec_result);
                    $log_text = "<h2>Running flvtool2: $cmd_flvtool</h2>";
                    write_log($log_text, $log_file_name, $debug, 'html');
                }
            }
        }
        else

This tells vshare to skip the encoding process for .flv files and only insert the meta data in to the .flv file. Now vShare wil convert all .flv files and add the watermark to all uploaded videos.

Please let me know if this did or did not work. Thanks

**vetty** · 12-22-2010, 08:48 PM

Thank you zelda180,

I have uploaded the file and made the necessary changes.

PHP Code:


/home/YOUR_USERNAME/public_html/include/settings/flvid.log 2>&1 ";

I don't have a file named flvid.log include settings.
The only files inside are upload.php, video_conversion.php and watermark_flvideo.png
I have changed YOUR_USERNAME in TWO instances of the code given (ie., cpanel username)

After uploading a video, It said uploaded successfully.
Previously it used to give a message as:

This time it was different:- It gave as, pl refer image.

Below is the result:

Admin Panel:

Edit Video:

Uploaded videos was not published on the site.Where i went wrong ???

**zelda180** · 12-23-2010, 03:27 AM

It sounds like there is something wrong with your video_conversion.php file. That is also why you recived the "uploaded successfully" message. Can you copy and past the /include/settings/video_conversion.php code or upload the file so that I can check.

Also....

1. What dose the status say in your Process Queue in your admin panel?

2. Did you add the code below at the end of your video_conversion.php file?

Code:

$convert_flv = $cmd_all;

3. The /include/settings/flvid.log file is a more detail conversion log that is created during the video conversion and for some reason it is not being created.

This is my video_conversion.php file code

Code:

<?php

//ffmpegflv - ffmpeg codec 11-2-10 converts to .flv With Watermark
$cmd_ffmpegflv = "$config[ffmpeg] -i '$video_src' -s 320x240 -f flv -b 600k -acodec libfaac -ab 16k -vf 'movie=0:png:/home/YOUR CPANEL NAME/public_html/include/settings/watermark_flvideo.png [wm];[in][wm] overlay=1:0:0 [out]' $video_flv > /home/YOUR CPANEL NAME/public_html/include/settings/flvid.log 2>&1 ";

$cmd_all = $cmd_ffmpegflv;

$convert_3gp = $cmd_all;
$convert_mp4 = $cmd_all;
$convert_mov = $cmd_all;
$convert_asf = $cmd_all;
$convert_mpg = $cmd_all;
$convert_avi = $cmd_all;
$convert_mpeg = $cmd_all;
$convert_wmv = $cmd_all;
$convert_rm = $cmd_all;
$convert_dat = $cmd_all;
$convert_flv = $cmd_all;
