Question

我想要流式传输mp4，为此我读到了关于ffserver的信息所以我搜索和阅读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：
安装了1-A win 8和最后一个VLC 2-A Ubuntu 13，最后一个ffmpeg包。
3-ffserver.conf文件保存到/ etc /并从http://ffmpeg.org/sample.html复制（我只是复制新文件中的文本）。
4 - 运行此命令：ffserver -f /etc/ffconfig.conf，结果为：

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，结果如下：

7-我看错了，我找不到为什么会这样，我哪里出错了！

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

编辑：

我安装了真实的ffmpeg，例如此链接：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ppa:mc3man/trusty-media以获取最后一个版本）：

任何人都可以给我一些我应该进行测试的确切命令吗？（我知道这就像初学者问题，但我读了doc并尽可能地测试了一切，但仍然没有运气）

您无法使用ffserver传输mp4个视频，因为它在文件头中包含全局元数据，这使得无法进行随机流访问。您可以选择其他格式，例如webm或使用MPEG-2传输流（Apple的HLS）。请参阅https://superuser.com/questions/563591/streaming-mp4-with-ffmpeg
