MP4 Content-Type Header

Hello All,

I am noticing when I run curl on a MP4 file I get the
application/octet-stream content type:

curl -I

HTTP/1.1 200 OK
Content-Type: application/octet-stream

Is there a reason why it wouldn't be "video/mp4"?

A few users have said "it is causing issues in players". (vague I know)

Here is the vhost: (very
long to paste in here IMO, if I am breaking a rule I am sorry, I will
paste it in the email from now on)

nginx version: nginx/1.2.0

configure arguments: --with-http_stub_status_module
--with-http_ssl_module --with-http_secure_link_module

Thanks in advance!
