Question

我正在尝试使用avserver程序包重新传输我的IP摄像机的流，以便能够记录此流并从远程访问它而无需从摄像机流式传输两次，以避免超载无线网络。

在链接https://libav.org/avserver.html之后，我想出了以下命令：

avserver -f /etc/avserver.conf & avconv -i http://user:password@192.168.1.121/videostream.asf http://localhost:80/feed1.ffm

这给了我以下输出

当我尝试使用

通过VLC media player打开此流时

http://192.168.1.15/test.asf

我得到以下额外输出

Mon Jan 13 20:17:39 2014 192.168.1.6 - - [GET] "/test.asf HTTP/1.1" 200 115s dup=12210 drop=0

Mon Jan 13 20:17:39 2014 Codec for stream 1 does not use global headers but container format requires global headers

我对VLC媒体播放器一无所知。我不太确定发生了什么或如何解决它，所以任何对此的启发都会非常受欢迎。

Answer 1

请尝试使用其他格式，如mp3

只是

sudo vim /etc/avserver.conf

使用

注释掉该部分

#<stream test.asf>
#</Stream>

取消注释mp3部分并尝试使用它。

<stream test.mp3></Stream>

如果您正在处理仅仅是音频的流，这将有效。

视频

只需使用

的未注释部分

<Stream test1.mgp><Stream>

使用'avserver'将输入流输入到流输出
