Hello,
I want to be sure that user uploaded files are real videos or pictures, but not just a piece of text renamed to textfile.jpg. What are the ways to ensure?
I see the only way: detect type of file by it's extension and then, depending on file type, try to get information about it (by Imagemagick or ffmpeg).
Is there any other ways?
Thank you.
