使用ffserver开始流简单mp4
使用ffserver开始流简单mp4
提问于 2015-02-10 15:34:32
我想要流一个mp4，为此，我阅读了有关ffserver的内容。
因此，我搜索和读取ffserver文档，但仍然不能流一个简单的文件。
为此，我做了以下工作：
1-一个win 8和最后一个VLC安装。
2-一个Ubuntu 13与最后的ffmpeg包。
3-保存到/etc/并从http://ffmpeg.org/sample.html复制的http://ffmpeg.org/sample.html文件(我只是在一个新文件中复制文本)。
4-运行以下命令：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和服务器状态是OK.It显示了4流: test1.mpg、test.asf、stat.html、index.html。
6-运行以下命令：ffmpeg -i test.mp4 http://localhost:8090/feed1.ffm，这是结果：

Error opening filters!7-我看错了，我找不到为什么会发生这种事，也找不到我哪里出错了！
到目前为止，我阅读了许多有关ffserver的示例和教程，但大多数都是关于实时流的，但我只想流一些mp4文件。
编辑：
我安装了真正的ffmpeg，如以下链接：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，以便最后发布)：

Error opening filters!有人能给我准确的命令，我应该运行测试吗？
(我知道这就像初学者的问题，但我读了文档，并尽我所能测试一切，但仍然没有运气)

您不能使用ffserver对mp4进行流处理，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。您可以选择另一种格式，如webm或使用MPEG-2传输流(Apple的HLS).See https://superuser.com/questions/563591/streaming-mp4-with-ffmpeg
