Nginx - MP4 HTTP 流问题

Question

我目前正在使用 Nginx 通过 HTTP 将我的 Mp4 文件提供给客户端。 我的大多数客户都在使用 XBMC 观看视频。其中一些报告错误：他们无法打开文件。 在我这边，我没有看到任何错误。每次访问都被授权（200），但我可以在我的日志中看到一个模式。当客户可以访问视频时，我只看到 2 行这样的：

123.456.789.123 - - [12/Jan/2014:01:19:34 -0500] "HEAD /myvideo.mp4?key=abc123456789 HTTP/1.1" 200 0 "-" "XBMC/11.0 Git:20120321-14feb09 (Windows NT 6.1;WOW64;Win64;x64; http://www.xbmc.org)"
123.456.789.123 - - [12/Jan/2014:01:20:05 -0500] "GET /myvideo.mp4?key=abc123456789 HTTP/1.1" 200 5964015 "-" "XBMC/11.0 Git:20120321-14feb09 (Windows NT 6.1;WOW64;Win64;x64; http://www.xbmc.org)"

并在错误日志中

2014/01/12 01:20:05 [info] 8661#0: *24936 writev() failed (104: Connection reset by peer) while sending mp4 to client, client: 123.456.789.123, server: cdn.domain.com, request: "GET /myvideo.mp4?key=abc123456789 HTTP/1.1"

当它起作用时：

在错误日志中

大多数情况下，客户在观看超过 90 分钟的视频时会遇到问题。

这是我的配置：

worker_processes  4;

pid         nginx.pid;

events {
    worker_connections  19000;
}

worker_rlimit_nofile    20000;

                mp4_max_buffer_size 5m;
        }

        location = /auth {

                proxy_pass_request_body off;

        location = /50x.html {

        }

    }



}

你知道有什么问题吗？

谢谢

Answer 1

你需要添加：

mp4_max_buffer_size 4096M;

对于 90 分钟以上的视频，您的缓冲区太小。
