It would be nice to generate DVD discs from video files or cameras in a simple automated way.

Video specs

  • mpeg2 av muxed stream
  • Bit rate from 4Mb/s - 10 Mb/s

Audio specs

  • mpeg1-layer2
  • AC3
  • PCM
  • Must be 48kHz sample rate


  • A directory of video files numbered to indicate their order


  • A DVD image file, or
  • A finished DVD if the machine has a DVD writer


apt-get install debian-multimedia-keyring dvdauthor mjpegtools imagemagick toolame


Here is the basis of a Make file that will eventually perform the whole process from file encoding to burning. It does not work at the moment, but is well documented.

	dd if=/dev/zero bs=4 count=1920 | toolame -b 128 -s 48 /dev/stdin menu/audio.mp2
