I am working on a script that lets you upload all kinds of video and images. I am wornding if ImageMagick can be used to take a snapshoot of the video and then display it as a image. showing the image on main page.

the script I am using is wrote in php. also my hosting company has imagemagick installed.

thanks for any information . if a script has been written you someone tell me where to get it and if not any information link would be great!

ffmpeg does the job
especially if you have multiple video formats i would doubt magicks ability to extract (key) frames
ffmpeg has lots of filters for almost every possible codec

I think it can and would search the user section as this would have come up before.

thanks my hosting company does not support ffmpeg that is why I am looking to program something different

I searched and did not see a answer. I guess I could have mist it. thanks

I believe that IM uses ffmpeg to do its work on video. That delegate library is needed with IM.

I found this
http://www.imagemagick.org/Usage/video/
and using below code and it will not create a .gif file any thoughts?

<?php

$name = 'cat.avi';
$new_name = 'cat.gif';
$max_width = "90";
$max_height = "90";

exec("convert -quiet -delay 1 $name $max_widthx$max_height $new_name");
print("New image size:".$new_name.$name." ");

echo "<img src=\"".$name."\">";
echo "<img src=\"".$new_name."\">";
?>

you probably need the full path to convert, usually at /usr/local/bin or /usr/bin

try this

<?php
exec("/usr/local/bin/convert -version",$out,$returnval);
print_r($out[0]);
?>

or

in command line try

find /usr | grep "convert"

or

sudo find / | grep "convert"

or

sudo find / | grep "convert"

my paths are

ImageMagick /usr/bin/
ImageMagick (C) /usr/local/bin/convert

I tried this and still will not work

<?php

$name = 'cat.avi';
$new_name = 'cat.gif';
$max_width = "90";
$max_height = "90";

exec(" /usr/local/bin/convert -quiet -delay 1 $name $max_widthx$max_height $new_name");
print("Names:".$new_name.$name." ");

echo "<img src=\"".$name."\">";
echo "<img src=\"".$new_name."\">";
?>

see if it runs from the command line or what errors it tells you and report back.

On the surface this makes no sense for correct syntax:

convert -quiet -delay 1 $name $max_widthx$max_height $new_name

to what does the WidthxHeight refer?

Is that a subsection of the image or a crop or a resize? If the latter two, then you need some operator such as -crop or -resize, if the former, then the size must be specified as image.png[WidthxHeight+xoffset+yoffset] the brackets are important as are the offsets

I changed to

http://www.imagemagick.org/Usage/video/

<?php

$name = 'cat.avi';
$new_name = 'cat.gif';

exec(" /usr/local/bin/convert -quiet -delay 1 $name $new_name");
print("Names:".$new_name.$name." ");

echo "<img src=\"".$name."\">";
echo "<img src=\"".$new_name."\">";
?>

but still do not get a cat.gif I can not run from command line. is there away to output error message to screen?

try adding the returnval and print_r as in

<?php
exec("/usr/local/bin/convert -version",$out,$returnval);
print_r($out[0]);
?>

when I add

<?php
exec("convert -version",$out,$returnval);
print_r($out[0]);
?>[/quote]

I get
Version: ImageMagick 6.3.9 12/10/08 Q16 http://www.imagemagick.org

Try:

Code: Select all

<?php

$name = 'cat.avi';
$new_name = 'cat.gif';

$array=array();
echo "<pre>";
exec(" /usr/local/bin/convert $name -quiet -delay 1 $new_name 2>&1", $array); 
echo "<br>".print_r($array)."<br>"; 
echo "</pre>";
print("<b>Names:</b>".$new_name.$name."<br>"); 

echo "<img src=\"".$name."\">";
echo "<img src=\"".$new_name."\">";
?>

When I run this I get:

Array
(
[0] => convert: no tag found `avi:decode' @ delegate.c/InvokeDelegate/863.
[1] => convert: missing an image filename `cat.gif' @ convert.c/ConvertImageCommand/2822.
