• FFMPEG & MistServer : RTMP Input/Output error

  17 octobre 2017, par brewcrazy

  I have an IP camera that outputs a RTSP stream that I’m trying to use to display a live feed on my website. This is a small site that only my wife and I will access so I’m trying to use a free streaming service. For that reason, I’ve decided to try MistServer’s open source option.

  I currently have downloaded MistServer and have it running without installation on my mac (sudo ./MistController). With MistServer running, I have a stream set up and default protocols configured. The stream is configured as follows :

  stream name: ipcam
  
  source: push://

  The configuration page gives me the following source to push to :

  RTMP full url: rtmp://127.0.0.1/live/ipcam
  
  RTMP url: rtmp://127.0.0.1/live/
  
  RTMP stream key: ipcam

  In the streams view, the stream’s status is unavailable, but I’m assuming this is because it isn’t receiving an input. I haven’t been able to confirm this via documentation.

  Here is the FFMPEG command that I am running and the error that I’m getting :

  ffmpeg -rtsp_transport tcp -i rtsp://<user>:@:554/live0.264 -acodec copy -vcodec copy -f flv rtmp://127.0.0.1/live/ipcam

  I can’t determine from this error if the issue is the FFMPEG command or my MistServer configuration.
