Convert audio from one format to other using ffmpeg

  • Convert wav format to dts format
     ./ffmpeg -i ~/sine_440Hz_2ch.wav -codec dts -strict -2 ~/sine_440Hz_2ch.dts 
  • Use mka container for above dts file
     ./ffmpeg -i ~/sine_440Hz_2ch.dts -vn -acodec copy -f matroska ~/sine_440Hz_2ch.mka 
  • Convert file from one container format to other
     ffmpeg -i input.mp4 -vcodec copy -acodec copy output.mkv 
  • Convert wav to ac3 format
     ./ffmpeg -i ~/sine_500Hz_2ch.wav -acodec ac3_fixed -ab 768k -ar 48000 test.ac3 
  • Use mka container for ac3
     ./ffmpeg -i test.ac3 -vn -acodec copy -f matroska ~/sine_500Hz_2ch-ac3.mka
