ubuntu - 使用 ffserver 开始流式传输简单的 mp4

Question

我想流式传输 mp4，为此我阅读了有关 ffserver 的内容。
所以我搜索并阅读了 ffserver 文档，但仍然无法流式传输一个简单的文件。
为此，我做了这些:
1-A win 8 和最后安装的 VLC。
2-带有最后一个 ffmpeg 包的 Ubuntu 13。
3-A ffserver.conf 文件保存到/etc/并从 http://ffmpeg.org/sample.html 复制(我只是将文本复制到一个新文件中)。
4-运行此命令:ffserver -f/etc/ffconfig.conf 结果如下:

avserver version 0.8.13-6:0.8.13-0ubuntu0.13.10.1, Copyright (c) 2000-2014 the Libav developers
  built on Jul 15 2014 13:53:49 with gcc 4.8.1
Tue Feb 10 07:29:07 2015 AVserver started.

5-检查 http://localhost:8090/stat.html服务器状态正常。它显示了 4 个流:test1.mpg、test.asf、stat.html、index.html。
6-运行此命令:ffmpeg -i test.mp4 http://localhost:8090/feed1.ffm 这是结果:

7-我查看错误，但找不到发生这种情况的原因和出错的地方!

到目前为止，我阅读了很多关于 ffserver 的示例和教程，但其中大部分是关于直播的，但我只想流式传输一些 mp4 文件。

编辑:

我像这个链接一样安装了真正的 ffmpeg:https://askubuntu.com/questions/373322/how-to-replace-avconv-with-the-real-ffmpeg-and-have-it-work-right但同样的错误(只需将 ppa 更改为上一个版本的 ppa:mc3man/trusty-media):

任何人都可以给我确切的命令，我应该为测试运行吗？
(我知道这就像初学者的问题，但我阅读了文档并尽我所能测试了所有内容，但仍然没有运气)

您无法直播 mp4使用 ffserver 的视频，因为它在文件头中包含全局元数据，这使得随机流访问变得不可能。您可以选择其他格式，例如 webm或使用 MPEG-2 传输流(Apple 的 HLS)。参见 https://superuser.com/questions/563591/streaming-mp4-with-ffmpeg
