• FFMPEG - Stream discovered after head already parsed [on hold]

  7 février 2014, par John Doe

  I am trying to live transcode an RTMP stream to another RTMP HLS stream using the following command :

  ffmpeg -re -i rtmp://localhost/videochat/testing -c:v libx264 -c:a:0 libfaac -b:a:0 480k -f flv rtmp://localhost:12345/hls/mystream;

  However I receive the following error and the transcoding never begins :

  Consider increasing the value for the 'analyzeduration' and 'probesize' options

  Stream #0:1: Data: none
  
  Codec AVOption b (set bitrate (in bits/s)) specified for output file #0 (rtmp://localhost:12345/hls/mystream) has not been used for any stream. The most likely reason is either wrong type (e.g. a video option with no video streams) or that it is a private option of some encoder which was not actually used for any stream.
  
  Output #0, flv, to 'rtmp://localhost:12345/hls/mystream':

  If anyone has ever dealt/solved this problem before, can you please share as I have been trying to solve this for 2 days but to no avail !
