• Trying to stream to multiple RTMPs with tee throws : Output file #0 does not contain any stream

  27 août 2020, par user33276346

  I'm trying to stream one file to multiple rtmps. The following command streams ok to one endpoint :

  


  ffmpeg -re -stream_loop 10 -i input.mp4 -c copy -f flv rtmps://x4t-myamsacc-usct.channel.media.azure.net:2935/live/x4t/x4t


  


  This one does not :

  


  ffmpeg -re -i input.mp4 -c copy -f tee "[f=flv]rtmps://x4t-myamsacc-usct.channel.media.azure.net:2935/live/x4t/x4t"


  


  Throws this error :

  


  Output file #0 does not contain any stream


  


  Once I can do it for one, I plan to do it for more. What could I be doing wrong ? This is the console log :

• How can I capture RTSP stream with FFMPEG continously and later decode a video

  17 avril 2020, par İsmet

  I have got a rtsp stream from camera. I don't want rtsp to mp4 file convert because that give a file like 10minute video,1 hour video. But I wanna search a specific date in stream (e.g 17.04.2020 15.00.00-16.15.00). So it have integrity data.

  



  

  



  Summary : how can I storage this rtsp stream and convert a video type (mp4,avi) with specific time part of data when I want it ?

  



  Note : Sorry for my weak Englis, I hope image tells what I want.
