下列的這，我正在嘗試透過網路串流傳輸影片。
設定為：
me@kaffeesatz:~$ vlc screen:// --screen-left=67 --screen-top=53 --screen-width=800 --screen-height=600 --screen-fps=60 --sout '#transcode{vcodec=theovb=800,scale=1,width=800,height=600,acodec=none}:http{mux=ogg,dst=localhost:8181/graph}'
但是當我嘗試在另一台電腦上從 vlc 開啟 the.ip.address:8181/graph 時，收到錯誤訊息：
Your input can't be opened:
VLC is unable to open the MRL 'http://the.ip.address:8181/graph'. Check the log for details.
我在這裡做錯了什麼？
同時，我驗證了我可以在我正在進行串流的機器上打開串流。但是從另一台電腦開啟串流仍然不起作用。
這是日誌輸出：

答案1
在伺服器上設定 VLC 時，不要指定 localhost 作為目標，只需指定連接埠號碼：
vlc screen:// --screen-left=67 --screen-top=53 --screen-width=800 --screen-height=600 --screen-fps=60 --sout '#transcode{vcodec=theovb=800,scale=1,width=800,height=600,acodec=none}:http{mux=ogg,dst=:8181/graph}'
