使用 ffserver 开始流简单的 mp4 [英] Begin stream simple mp4 with ffserver

问题描述

我想流式传输 mp4，为此我阅读了 ffserver.
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(我只是在新文件中复制文本).
4-运行此命令:ffserver -f/etc/ffconfig.conf，这是结果:

I want to stream a mp4 and for this I read about ffserver.
So I search and read ffserver documentations but still cant stream a simple file.
For this I done these:
1-A win 8 and last VLC installed.
2-A Ubuntu 13 with last ffmpeg package.
3-A ffserver.conf file saved to /etc/ and copied from http://ffmpeg.org/sample.html (I just copy text in a new file).
4-Run this command : ffserver -f /etc/ffconfig.conf and this is result :

  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.它向我展示了 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:

5-Check http://localhost:8090/stat.html and server status is OK.It shows me 4 stream : test1.mpg,test.asf,stat.html,index.html.
6-Run this command : ffmpeg -i test.mp4 http://localhost:8090/feed1.ffm and this is result :

7-我查看错误，但找不到为什么会发生这种情况以及我哪里出错了！

7-I look at error and I can not find why this happen and where I go wrong!

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.

Until now I read many sample and tutorials about ffserver but most of them is about live streaming but I just want to stream some mp4 files.

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 ppa:mc3man/trusty-media 即可获得最新版本):

I installed real ffmpeg like this link : https://askubuntu.com/questions/373322/how-to-replace-avconv-with-the-real-ffmpeg-and-have-it-work-right but same error (Just change ppa to ppa:mc3man/trusty-media for last release):

谁能给我确切的命令，我应该运行以进行测试吗?
(我知道这就像初学者的问题，但我阅读了文档并尽可能地测试了所有内容，但仍然没有运气)

Can any one give me exact commands that I should run for test?
(I know this is like beginners problem but I read doc and test everything as I can but still no luck)

推荐答案

您不能使用 ffserver 流式传输 mp4 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).请参阅 https://superuser.com/questions/563591/streaming-mp4-with-ffmpeg

You can't stream mp4 vidoes using ffserver because it contains global metadata in the file header, which makes random stream access impossible. You can choose another format like webm or use MPEG-2 Transport Streams (Apple's HLS).See https://superuser.com/questions/563591/streaming-mp4-with-ffmpeg
