• Can't publish stream on Wowza Streaming engine. Server creates and immediately destroy stream

  1er novembre 2016, par user2365252

  I have set up the Wowza Streaming Engine on the AWS with application name "live". I have opened all necessary ports for the Wowza on the AWS to receive and re transmit the video stream.

  I am taking stream from NVR in the LAN and publishing the video stream from Ubuntu machine using FFMPEG with below command on to Wowza Server.

  ffmpeg -v debug -i "rtsp://888888:888888@192.168.1.5:554/cam/realmonitor?channel=1&subtype=1"  -acodec copy -vcodec copy -sn -f flv "rtmp://xx.xx.xx.xx:1935/live/channel1 live=true pubUser=un pubPasswd=pw"

  It gives me following error after around 60 secs on the terminal.

  Successfully parsed a group of options.
  
  Opening an output file: rtmp://xx.xx.xx.xx:1935/live/channel1 live=true pubUser=un pubPasswd=pw.
  
  Parsing...
  
  Parsed protocol: 0
  
  Parsed host    : xx.xx.xx.xx

  RTMP_Connect0, failed to connect socket. 110 (Connection timed out)
  
  rtmp://xx.xx.xx.xx:1935/live/channel1 live=true pubUser=un pubPasswd=pw: Unknown error occurred

  So, I checked the Wowza server log for any clue and I found this.

  So basically the server authentication is done correct but server starts the stream and stops immediately.

  Can anyone please give me some pointer to look for this error ?
