 > FYI, I'm still experiencing this issue in WP 4.7.3 when attempting to
 upload OGV (OGG Video) files.

 Are you comfortable enough with PHP to try and run a quickie test?

 If so, take the code below and save it to the root of your WordPress
 installation (same folder as `wp-load.php`), call it `test.php` or
 something:
 {{{#!php
 <?php
 require_once('wp-load.php');
 header("Content-type: text/plain");

 //This should point to an actual ogg file.
 $ogfile = 'test.ogv';

 try {
         $finfo = finfo_open(FILEINFO_MIME_TYPE);
         $real_mime = finfo_file($finfo, $ogfile);
         finfo_close($finfo);
         echo "MIME: $real_mime";
 } catch(Exception $e){
         echo 'Could not use fileinfo.';
 }
 }}}

 This tiny script is expecting an OGV file called `test.ogv` in that same
 directory. I recommend using FTP to upload a copy of the OGV you were
 unable to upload through WordPress (renamed thusly).

 Once the `test.php` and `test.ogv` are in place, visit
 http://yourdomain.com/test.php in a web browser. What does it output? On
 my server, I see: `MIME: video/ogg`

 (After you've gotten a response, feel free to delete the test files.)
