[英]Begin stream simple mp4 with ffserver
我想流一個mp4,為此我讀到了關於ffserver的內容。
所以我搜索和閱讀ffserver文檔,但仍然無法流式傳輸一個簡單的文件。
為此,我做了這些:
安裝了1-A win 8和最后一個VLC。
2-A Ubuntu 13,帶有最后一個ffmpeg包。
3-ffserver.conf文件保存到/ etc /並從http://ffmpeg.org/sample.html復制(我只是將文本復制到新文件中)。
4 - 運行此命令: ffserver -f /etc/ffconfig.conf
,結果如下:
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 - 檢查http:// localhost:8090 / stat.html ,服務器狀態是OK。它顯示了4個流:test1.mpg,test.asf,stat.html,index.html。
6 - 運行此命令: ffmpeg -i test.mp4 http://localhost:8090/feed1.ffm
,結果如下:

7-我看錯誤,我找不到為什么會發生這種情況,哪里出錯了!
到目前為止,我閱讀了很多關於ffserver的示例和教程,但其中大部分都是關於實時流式傳輸,但我只想流式傳輸一些mp4文件。
編輯:
我安裝了真正的ffmpeg像這樣的鏈接: https : //askubuntu.com/questions/373322/how-to-replace-avconv-with-the-real-ffmpeg-and-have-it-work-right但同樣的錯誤(Just將ppa更改為ppa:mc3man/trusty-media
for last release):

任何人都可以給我准確的命令,我應該運行測試嗎?
(我知道這就像初學者的問題,但我讀了doc並盡可能地測試了一切,但仍然沒有運氣)
您無法使用ffserver傳輸mp4
因為它在文件頭中包含全局元數據,這使得無法進行隨機流訪問。 您可以選擇其他格式,如webm
或使用MPEG-2傳輸流(Apple的HLS)。請參閱https://superuser.com/questions/563591/streaming-mp4-with-ffmpeg
