Nginx MP4 Pseudo Streaming won't stop when paused

Question

Here's my nginx configuration within the server block:

location /mp4/ {
    mp4;
    mp4_buffer_size     6M;
    mp4_max_buffer_size 20M;
    limit_rate 260k;
    limit_rate_after 3m;
}

I also have the following in the http block:

http {
    sendfile        on;
    tcp_nopush      on;
    tcp_nodelay     on;
    sendfile_max_chunk 512k;
}

I loaded the 1.2GB test file http://example.com/mp4/sample.mp4 directly in Chrome browser.

A default built-in player is shown and I can playback with seek and scrub without problem.

But when the video is paused, the rest of the clip is still being downloaded.

I noticed this by monitoring my bandwidth usage on the server side.

I read that the mp4_max_buffer_size and mp4_buffer_size are meant to be setting memory usage on the server side.

How do I prevent the client side from continuously downloading the video in the background when video is paused, so that it won't waste the client's and my server's bandwidth?

Answer 1

The server just fulfills requests. Its up the the browser how much data it requests.
