Upload to Youtube with progress bar from Laravel , Dropzone , and Google Api.

Hi , i want to ask if there is a way that i can get the progress from youtube while the video is upload / processing ? I'm using Laravel 5.4 , Dropzone and this Youtube Wrapper https://github.com/JoeDawson/youtube for the Google API : Dropzone works fine and shows the progress until the file is upload to the server but hangs when the the video is processing in youtube , i tried to use some ob_flush but don't show the response. Anyone had done something like this ?

Thanks.
