我想流式传输 mp4,为此我阅读了有关 ffserver 的信息。
所以我搜索并阅读了 ffserver 文档,但仍然无法流式传输简单文件。
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-保存到 /etc/ 并从http://ffmpeg.org/sample.html复制的 ffserver.conf 文件(我只是将文本复制到新文件中)。
4-运行此命令:ffserver -f /etc/ffconfig.conf
这是结果:
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并且服务器状态正常。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:
ffmpeg 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

7-我查看错误,但找不到发生这种情况的原因以及哪里出错了!
到目前为止,我阅读了许多关于 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(只是将 ppa 更改ppa:mc3man/trusty-media
为最新版本):

任何人都可以给我应该运行测试的确切命令吗?
(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)
