PVVideo is a class designed to manipulate video files and transcoding to various formats.
PVVideo works with all kinds of audio files: mp4, mov, ogg, etc. It utilizes command tools like FFMPEG to do the transcoding and will return the results from the command line.
Example:
//Set the file to be converted
$old_file = '/path/to/file/video.mov';
//Set the path of the new file
$new_file = '/path/to/file/video.mp4';
//Options to pass to the FFmpeg or other conversion tools
//The following will place a -f infront of the input
$options = array('input_f' => '');
//Run the conversion
PVVideo::init();
PVVideo::convertAudioFile($old_file, $new_file , $options );

This can either be the name of the class or an object whose methods will be adapted to another class. The class should be included or be autoloaded by this point.
