【nginx】rtmpt(tunnel by http:80) to rtmp:1935

Posted on | In , , , ,

目標

  1. 透過 nginx，將 流 透過 rtmpt:80 的 protocol 轉送給 rtmp:1935 protocol
  2. 推流 ffmpeg / OBS, protocol : rtmpt
  3. 收流 VLC player, protocol : rtmp
  4. 額外測試 : 送 rtmpt 給 ossrs
  5. 延伸
    1. 透過 rtmpts (tunnel by https)，加入 ssl
    2. 透過 rtmps，直接接收 rtmps 流，並 proxy 轉送給 ossrs

env

  • push streaming tool
    • ffmpeg 3.4 :
      • 將桌面影像上傳 : ffmpeg -f avfoundation -i "1" -vcodec libx264 -preset ultrafast -acodec libfaac -f flv rtmpt://localhost/demo/desktop
    • OBS
      • 將制式的 mp4 檔案丟到 rtmpt://localhost/demo/video
    • wrong : [tcp @ 0x7f830d5153c0] Connection to tcp://localhost:80 failed (Connection refused), trying next address
      • 會自動檢查 127.0.0.1
  • watch streaming tool
    • VLC player
  • docker :
    • ossrs
    • nginx:latest (1.13.6)
      • rtmp server
      • rtmpt server
  • compiler first
