在windows上安装php ffmpeg

Question

我下载了ffmpeg并安装它 Composer 。当我尝试使用基本使用代码时，我收到了这个错误。在 bin 文件夹中，我有 ffmpeg , ffplay和 ffprobe exe文件。我还为 c:ffmpeg\bin 设置了环境变量.

Fatal error: Uncaught exception
'Alchemy\BinaryDriver\Exception\ExecutableNotFoundException' with message 'Executable not found, proposed : c:\ffmpeg\bin\binffprobe.exe' in C:\xampp\htdocs\core\vendor\alchemy\binary-driver\src\Alchemy\BinaryDriver\AbstractBinary.php:160 Stack trace: #0

这是我的 php 代码；

  require_once 'vendor/autoload.php';
  $ffmpeg = \FFMpeg\FFMpeg::create([
'ffmpeg.binaries'  => 'c:\ffmpeg\bin\binffmpeg.exe',
'ffprobe.binaries' => 'c:\ffmpeg\bin\binffprobe.exe' 
  ]);

  $video = $ffmpeg->open('video.mpg');
 $video
->filters()
->resize(new FFMpeg\Coordinate\Dimension(320, 240))
->synchronize();
 $video
->frame(FFMpeg\Coordinate\TimeCode::fromSeconds(10))
->save('frame.jpg');
$video
->save(new FFMpeg\Format\Video\X264(), 'export-x264.mp4')
->save(new FFMpeg\Format\Video\WMV(), 'export-wmv.wmv')
->save(new FFMpeg\Format\Video\WebM(), 'export-webm.webm');`

确保您提供正确的二进制文件路径，此错误只是因为脚本无法找到二进制文件，

所以也许如果我没有错，你给出了错误的 exe 文件名

改变这个

$ffmpeg = \FFMpeg\FFMpeg::create([
    'ffmpeg.binaries'  => 'c:\ffmpeg\bin\binffmpeg.exe',
    'ffprobe.binaries' => 'c:\ffmpeg\bin\binffprobe.exe' 
]);

进入这个

$ffmpeg = \FFMpeg\FFMpeg::create([
    'ffmpeg.binaries'  => 'c:\ffmpeg\bin\ffmpeg.exe',
    'ffprobe.binaries' => 'c:\ffmpeg\bin\ffprobe.exe' 
]);

你重复 bin\bin 两次，

c:\ffmpeg\bin\binffprobe.exe

祝你好运，

这里只是将视频转换为 mp3 的示例代码

require_once 'vendor/autoload.php';
$ffmpeg = \FFMpeg\FFMpeg::create([
     'ffmpeg.binaries'  => 'ffmpeg\bin\ffmpeg.exe',
     'ffprobe.binaries' => 'ffmpeg\bin\ffprobe.exe' 
]);

$video = $ffmpeg->open('video.mp4');
//just in case you want to save thumbnail from video
$video
   ->frame(FFMpeg\Coordinate\TimeCode::fromSeconds(300))
   ->save('frame.jpg');
//extract audio
$video->save(new FFMpeg\Format\Audio\Mp3, 'audio.mp3');
