  Problem :

  Warning, using s16 intermediate sample format for resampling

  I've also tried changing the parameter

  From

  -ar 44100

  to

  -ar 11025

  Thanks !

  This audio file cannot be played in some players and I think it is

  Error while decoding stream #0.0

  What that mean and how can I avoid this ?

  Update :
  If you want to help, you may want to test that MP4 file, so, here is link - https://dl.dropbox.com/u/34111231/in.mp4

• FFmpeg saving rtmp live stream cuts off after 3 minutes

  20 janvier 2013, par user1636922

  I was playing with ffmpeg and was able to save a live stream to a file. The command to do so is :

  ffmpeg -re -i "rtmp://<ip addr="addr">/livestream live=1" -f h264 test.flv
  
  </ip>

  However, I have tested this twice, and both times ffmpeg stops after grabbing 3:28 worth of live video.

  The entire output is here :

  bash-4.2$ ffmpeg -re -i "rtmp://<ip addr="addr">/livestream live=1" -vcodec libx264 -f h264 test.flv

  Although I don't see any errors. It just looks like ffmpeg thought the stream had ended ? But that's not possible since it's a live stream.
