• Anomalie #2521 : Images dans upload et portfolio

  3 février 2012, par Suske -

  J’ajoute :

  En passant par le module documents de spip3, on peut insérer en quelques secondes 500 photos issues de /upload (c’est testé et rapide !) mais après, une fonctionnalité permettant un traitement global, par paquets de docs, serait un grand plus. Genre pouvoir sélectionner ou indiquer un (...)

• 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.
