• ffmpeg : getting video from http page streamed to youtube

  28 novembre 2014, par M-T-A

  I’m trying to configure ffmpeg to stream to youtube from ubuntu machine.

  I have my wifi camera streaming with format ’video/x-ms-asf’ on local http page.

  Then I use these commands in attempt to stream to youtube

  VBR="2500k" # Bitrate 
  
  FPS="20" # FPS 
  
  QUAL="medium" #ffmpeg quality
  
  YOUTUBE_URL="rtmp://a.rtmp.youtube.com/live2" # URL base
  
  
  
  SOURCE="http://192.168.9.XX/videostream.asf?user=admin&pwd=***" # Source of video
  
  KEY="KEY HERE" # youtube event key
  
  
  
  ffmpeg \
  
  -i "$SOURCE"  \
  
  -vcodec copy -pix_fmt yuv420p -preset $QUAL -r $FPS -g $(($FPS * 2)) -b:v $VBR \
  
   -ar 44100 -threads 6 -qscale 3 -b:a 712000 -bufsize 512k \
  
  -f flv "$YOUTUBE_URL/$KEY" 

  I get this output

  Suddenly the streaming stops and the terminal hangs. I’m not sure why. Is it because the video has no audio in streaming ?
