I think I understand the problem of the author of this question.
I've added an answere there - most likely, it has ssi or something
like enabled for all MIME types.

The 206 code indicates that "this was 200, but due to Range header
only part of the actual response is returned".

If you don't see the Accept-Ranges header added to a response, then
range requests are not supported.

If you don't see Accept-Ranges header added to responses to a
static mp4 file, then there is something wrong in your config.
Either a response is handled in a wrong location and ends up being
handled not by nginx, or there is a filter active for some/all
responses which may modify them and hence disables range support.

If you can't trace the problematic configuration and/or not sure
it's the case, you may start testing with a clean config. E.g.,
with trivial configuration like this:

http {
include mime.types;

server {
listen 8080;

location / {
mp4;
}
}
}

A request to static mp4 file results in:

$ curl -I http://localhost:8080/mp4/test.mp4
HTTP/1.1 200 OK
Server: nginx/1.7.3
Date: Fri, 27 Jun 2014 18:38:24 GMT
Content-Type: video/mp4
Content-Length: 7147296
Last-Modified: Fri, 15 Jun 2012 15:50:37 GMT
Connection: keep-alive
ETag: "4fdb59cd-6d0f20"
Accept-Ranges: bytes
