FFMPEG在命令行运行但不是PHP [英] FFMPEG running in Command Line but not PHP
问题描述
我正在使用ffmpeg构建窗口来制作视频缩略图。该命令在命令行中运行良好,但不适用于PHP exec方法。正在使用PHP 5.2.11
这是命令。
E:/ Documents and Settings / x / WINDOWS / ffmpeg-itsoffset -4 -vE:/ Program Files / Apache Software Foundation / Apache2.2 / htdocs / bs / files / videogal / c08c3d20eeb9083ed033577bd154cba6.flv-vcodec mjpeg -vframes 1 -an -f rawvideo -s 320x240E:/ Program Files / Apache Software Foundation / Apache2.2 / htdocs / bs / files / gallery / 8ff43b72b932d2a34e7a6733672ad4d6.jpg2>&$ 1
有人可以帮忙。我检查了他们似乎很好的权限。 GD已安装。
错误msg是'E:/ Documents'不被识别为内部或外部命令,可操作的程序或批处理文件
在我的路径中使用正斜杠,除了转义双引号
PHP函数
function ExtractThumb($ in,$ out)
{$ path = dbconf :: FFMPEG_PATH;
$ thumb_stdout;
$ errors;
$ retval = 0;
echo $ in;
//如果文件已经存在,请删除该文件
if(file_exists($ out)){unlink($ out); }
//使用ffmpeg从电影中生成一个缩略图
$ 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);
//排队处理
的错误if($ retval!= 0){$ errors [] =FFMPEG缩略图生成失败;
如果(!empty($ thumb_stdout))
{
foreach($ thumb_stdout as $ line)
{
echo $ line。 \\\
;
}
}
if(!empty($ errors))
{
foreach($ errors as $ error)
{
echo $ error。 \\\
;
}
}
}
$ in和$ out绝对路径这是我得到的

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))
{
foreach ($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;
