我試圖使用avserver包來重新流式傳輸我的IP攝像機的流，以便能夠記錄此流並以remotelly方式訪問它，而不必從第攝像頭，以避免無線網絡過載。使用'avserver'流輸入到流輸出
繼鏈接https://libav.org/avserver.html，我想出了下面的命令：
avserver -f /etc/avserver.conf & avconv -i http://user:[email protected]/videostream.asf http://localhost:80/feed1.ffm
這給了我下面的輸出

當我嘗試通過VLC media player打開這個流，使用
http://192.168.1.15/test.asf
我收到以下附加信息輸出

Mon Jan 13 20:17:39 2014 Codec for stream 0 does not use global headers but container format requires global headers
Mon Jan 13 20:17:39 2014 Codec for stream 1 does not use global headers but container format requires global headers
而我在VLC媒體播放器上什麼也沒得到。我不太確定究竟發生了什麼或如何修復，所以對此的任何啓發都將非常受歡迎。
的註釋掉部分添加'AVOptionVideo標誌+ global_header''AVOptionAudio標誌+ global_header'在avserver.conf
