• The YouTube live stream encountered a failure

  12 février 2024, par kuldeep chopra

  We are currently utilizing the ffmpeg library for streaming on YouTube Live. However, we have faced issues in a recent live streaming session that initially functioned correctly but encountered errors around the 13 to 15-minute mark. The error logs from FFmpeg during this session are as follows :

  


  Live Stream 1 Error :(Attempt 1)

  


  


  ffmpeg [flv @ 0x555c4bdfe680] Failed to update header with correct

  Live Stream 2 Error (Attempt 2) :

  


  


  Slave muxer #1 failed : Connection reset by peer, continuing with 1/2
slaves.

  


  


  It is crucial to note that we have conducted numerous live streams on YouTube without encountering this error previously ; this is the first instance of such an issue.

  


  We kindly request your assistance in investigating and providing insights into the underlying problem causing these error messages. Any guidance or support you can offer in resolving this issue would be greatly appreciated.

  


• Streaming live video from Windows to Android with FFmpeg

  29 avril 2018, par Alan Daniels

  I am capturing live video on a Windows PC and encoding it with FFmpeg. I can stream the content live to another PC using rtsp://[dest_ip:port]/live.sdp as FFmpeg’s output on the sender and using ffplay -rtsp_flags listen rtsp://[dest_ip:port]/live.sdp on the receiver. However, I have to run FFplay before starting the sender. Also, VLC cannot play the rtsp path :

  main debug: net: connecting to 127.0.0.1 port 5555
  
  main error: connection failed: Connection refused by peer
  
  access_realrtsp error: cannot connect to 127.0.0.1:5555
  
  access_realrtsp debug: could not connect to: 127.0.0.1:5555/live.sdp

  However, FFplay and VLC can play something like ffplay rtsp://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mov.

  On the Android side, I am using the Media API which can play content from a URI. It works with HTTP and RTSP (as far as I know).

  I’ve looked at FFmpeg’s streaming guide : https://trac.ffmpeg.org/wiki/StreamingGuide, but I am still confused about the difference between my path rtsp://[dest_ip:port]/live.sdp and rtsp://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mov.

  Do I need a streaming server in order to have my content accessible by URI ? Any recommendations since FFserver is depreciated ?
