Bug in detect file type (open method)

[mostafa-norouzi]

I noticed that for some Mp3 files, PHP-FFMpeg detect them as video format and if you want to cut part of that :

$audio = $ffmpeg->open( $file );
$audio->filters()->clip($start,$length );
$format = new \FFMpeg\Format\Audio\Mp3();
$audio->save($format,$target);

Below error raised :

Fatal error: Uncaught TypeError: FFMpeg\Filters\Video\ClipFilter::apply(): Argument #2 ($format) must be of type FFMpeg\Format\VideoInterface, FFMpeg\Format\Audio\Mp3 given, called in D:\wamp330\www\demo\PHP-FFMPEG\vendor\php-ffmpeg\php-ffmpeg\src\FFMpeg\Media\AbstractVideo.php on line 168 and defined in D:\wamp330\www\demo\PHP-FFMPEG\vendor\php-ffmpeg\php-ffmpeg\src\FFMpeg\Filters\Video\ClipFilter.php on line 61

So I think that it would be better if we can pass file type manually to [open] method and force class that act as audio file:

public function open($pathfile,$type="audio")
    {
