FFMPEG running in Command Line but not PHP
I am using ffmpeg build for windows to make video thumbnails . The command works well in command line but not from PHP exec method. am using PHP 5.2.11
Here is the command.
"E:/Documents and Settings/x/WINDOWS/ffmpeg" -itsoffset -4 -v "E:/Program Files/Apache Software Foundation/Apache2.2/htdocs/bs/files/videogal/c08c3d20eeb9083ed033577bd154cba6.flv" -vcodec mjpeg -vframes 1 -an -f rawvideo -s 320x240 "E:/Program Files/Apache Software Foundation/Apache2.2/htdocs/bs/files/gallery/8ff43b72b932d2a34e7a6733672ad4d6.jpg" 2>&1
Can somebody help. I checked the permissions they seem fine. GD is installed.
The error msg is 'E:/Documents' is not recognized as an internal or external command, operable program or batch file
Am using forward slashes in my paths except when escaping double quotes
The PHP function
function ExtractThumb($in, $out)
{$path=dbconf::FFMPEG_PATH;
$thumb_stdout;
$errors;
$retval = 0;
echo $in;
// Delete the file if it already exists
if (file_exists($out)) { unlink($out); }
// Use ffmpeg to generate a thumbnail from the movie
$cmd = "$path -itsoffset -4 -i $in -vcodec mjpeg -vframes 1 -an -f rawvideo -s 320x240 $out 2>&1";
echo $cmd;
exec($cmd, $thumb_stdout, $retval);
// Queue up the error for processing
if ($retval != 0) { $errors[] = "FFMPEG thumbnail generation failed"; }
if (!empty($thumb_stdout))
{
foreach ($thumb_stdout as $line)
{
echo $line . "\n";
}
}
if (!empty($errors))
{
foreac开发者_开发知识库h ($errors as $error)
{
echo $error . "\n";
}
}
}
funny enough if I run without the $in and $out absolute path this is what I get

Here's one of mine I've used in the past (granted I'm on a LAMP stack):
$cmd = "/usr/bin/ffmpeg -i ".$in." -y -an -sameq -vframes 1 -s 100x56 -ss 3 -t 0.001 ".$out;
You may also consider: http://ffmpeg-php.sourceforge.net/
You need to escape your command properly:
exec(escapeshellcmd($cmd), $thumb_stdout, $retval);
Also do you have PHP safe mode on?
You should check that $in
is a real file before trying to encode too.
are you properly escaping your backslashes, quotes etc.? Is there any error message?
The error message says it doesn't recognize it as a command. Its most probably your quoting. Check your quoting of white spaces. Escape the white spaces when necessary using slash "\ ". And where is your code snippet that calls exec()
?
Maybe try this:
$cmd = "\"$path\" -itsoffset -4 -i \"$in\" -vcodec mjpeg -vframes 1 -an -f rawvideo -s 320x240 \"$out\" 2>&1";
I use it this way::
exec("C:/wamp/bin/ffmpeg -i ./output4.mp4 -sameq -acodec libmp3lame -ar 22050 -ab 32 -f flv -s 320x240 ./output8.flv -vcodec mjpeg -vframes 4 -an -f rawvideo -s 320x240 ./pic008.jpg 2>&1");
Directly connected from WAMP SERVER.
Notice the:
./output4.mp4
That tells PHP that I am dealing with the current directory.
