Laravel 4 - PHP-FFMpeg - 进展

Question

I am using PHP-FFmpeg with laravel to create encodes of the clips uploaded to the app ( php-ffmpeg github ). The documentation says that transcoding progress can be monitored in realtime, by providing the 'progress' event callback.

$video  = $ffmpeg->open($originaldir);

$format = new $format_class();

$format->on('progress', function ($video, $format, $percentage) {
            echo("$percentage % transcoded");
});

The function is written in the controller but, how can I get the the $percentage variable out of the closure and show it in the view?

Update

I have tried to use this package to store the $percentage var into a js variable, so I could access it in the view: https://github.com/laracasts/PHP-Vars-To-Js-Transformer , but it doesn't seem to work. This is what I've tried to do in the controller:

JavaScript::put([
    'prog' => $percentage
]);

您需要将某个百分比 - 用户的会话，存储在某种类型的数据库中等 - 存储，并通过AJAX定期检索该值以显示给用户。
