• FFMPEG to Youtube Live - YouTube is not currently receiving data

  13 mars 2018, par Mickael Tzanakakis

  Since a while, I would like to stream a video to the Youtube Live with FFMPEG. I tried a lot of configurations differents but nothing to the Youtube Dashboard. Every time Youtube feel something :

  Launch in progress

  and finally :

  "YouTube is not currently receiving
  data for this stream. If you believe this is incorrect, ensure you’re
  sending a stream and that it is configured with the correct stream
  key."

  I tried those scripts :

  https://gist.github.com/olasd/9841772

  https://github.com/scivision/PyLivestream

  and a lot ffmpeg command but ... no result.

  Exemple :

  ffmpeg -r 24 -f image2 -s 1920x1080 -i test.mp4 -vcodec libx264 -crf 25 -pix_fmt yuv420p -f flv rtmp://a.rtmp.youtube.com/live2/KEY
  
  
  
  ffmpeg -re -i test.mp4 -c:v libx264 -preset veryfast -maxrate 3000k \ -bufsize 6000k -pix_fmt yuv420p -g 50 -c:a aac -b:a 160k -ac 2 \ -ar 44100 -f flv rtmp://a.rtmp.youtube.com/live2/KEY

  If I replace rtmp ://a.rtmp.youtube.com/live2/ by "stream.flv" for exemple, I have the good result in this file.

  Unfortunately the differents topic on this didn’t help me ;
  Any idea please ?

  Thank you !

  PS : I success only with a desktop software : OBS Studio but is not my goal.

• How to configure ffmpeg for streaming videos from Red5 into Youtube using youtube-v3-api ?

  28 mai 2018, par Alfonso Valdes

  You’ll see my problem is next :

  Currently I’m working to configure youtube-v3-api for live streaming of .flv videos on my Youtube channel using Red 5 service as stated on next link https://www.red5pro.com/docs/server/ffmpegstreaming.html, this is using next commands for streaming on Linux :

  ffmpeg  -i rtmp://127.0.0.1:1935/live/streamname live=1 timeout=2 -vcodec libx264 -s 640x480 -vb 500k -acodec libfdk_aac -ab 128k  -f flv rtmp://a.rtmp.youtube.com/live2/{Stream name/key}
  
  
  
  
  
  ffmpeg -rtsp_transport tcp -i rtsp://127.0.0.1:8554/live/streamname -acodec copy -vcodec copy -f flv rtmp://a.rtmp.youtube.com/live2/{Stream name/key}

  On this, neither RMTP nor RTSP protocols are working for streaming. Also, I have tried several codecs for audio and video configuring different sizes for each one of them, but none of those have worked.

  The root streaming videos are generated by an IOS/Android app still on development phase.

  The problem comes when no video is displayed on Youtube screen, regardless the video is being sent by Red5 (I confirmed this on my Red5 dedicated server on AWS) and received correctly by Youtube (confirmed by validating on Console), so I have come into a dead end on which I hope you could help me get through.

  Any idea of what could be a possible solution ?

  Thank you.
