• Sync voice with the music through ffmpeg. live karaoke FMS

  26 mars 2015, par LifeSoul

  Using the AMS (FMS) server.

  User voice broadcasts to the server.
  ffmpeg does mix of voice from rtmp and music from disk, and sends to the server

  The problem is that the voice or music, do not coincide in time.

  Is there a way to sync via ffmpeg ?

  Example

  -re -i DISK:/path/music.mp3 -i rtmp://x.x.x.x/karaoke/voice -filter_complex amix=inputs=2:duration=first,volume=2.000000 -ar 22050 -q:a 2 -ac 2 -f flv rtmp://x.x.x.x/karaoke/stream

  Time difference between 0.0-0.5 seconds (random)
