Cannot upload media files via Responsive File Manager

Question

Recently I started using Responsive File Manager tool as a plugin on TinyMCE, and it looked perfect at first but after some time I'm having problem uploading files of media type (mov, mpeg, m4v, mp4, avi, mpg, wma, flv...) throws an error :

Just my opinion:
I'm not good at complex level of programming but I think, maybe the error is generated by the attempt to create a Thumbnail of the uploading file (media type) so, is there any way to avoiding the creation of Thumbnails for mov, mpeg, m4v, mp4, avi, mpg, wma, flv...?

If need some extra details about anything please make me know. "Thank you before hand".

Answer 1

add this line to mime_type_lib.php

'mp4' => 'video/mp4',

on line 100

this worked for me.

Answer 2

Open filemanager/include/mime_type_lib.php and add 'mp4' => 'video/mp4', to the MIME types array. It will work.
