How can I use php-FFMpeg in laravel 4?

问题:

I am new to Laravel 4. I have installed php-ffmpeg in my local Laravel setup, but I need help on how to use this ffmpeg with Laravel 4?

Assuming that you already have ffmpeg installed on your localhost server, then in Laravel, you need to set the paths for the ffmpeg and ffprobe binaries, like so:

$ffmpeg = FFMpeg\FFMpeg::create(array(
         'ffmpeg.binaries'  => '/usr/local/Cellar/ffmpeg/2.1.3/bin/ffmpeg', 
         'ffprobe.binaries' => '/usr/local/Cellar/ffmpeg/2.1.3/bin/ffprobe', 
         'timeout'          => 3600, // The timeout for the underlying process
         'ffmpeg.threads'   => 12,   // The number of threads that FFMpeg should use
));

By doing so, then you can:

// set the path of the video file, which you might consider to get the input from the user 
$video = $ffmpeg->open('video.mpg');

// apply filters to resize the clip 
$video
  ->filters()
  ->resize(new FFMpeg\Coordinate\Dimension(320, 240))
  ->synchronize();

// crop a frame from a particular timecode
$video
  ->frame(FFMpeg\Coordinate\TimeCode::fromSeconds(10))
  ->save('frame.jpg');

// transcode clip
$video
  ->save(new FFMpeg\Format\Video\X264(), 'export-x264.mp4');

There are more examples provided in the PHP-FFMpeg documentation on github
