  • How to know if uploaded file is a video file [closed]

    How do I validate that an uploaded file is a video?

    How to know using exec with ffmpeg and php if the uploaded file or any file on the hard disk is a video or not?

    Turned out to use finfo for checking the mime, unsure if it is the best solution, but it appears everyone is happy by giving down votes instead of reasoning.

    Well, some of my videos have a mime of application octet-stream which makes finfo not the solution, LIKE I ASKED. I suppose with ffmpeg there might be an is_video() function somehow just that I couldn't find it.

    Trouble: http://mimeapplication.net/octet-stream
