FAQ no audio

From DVD-Slideshow

Jump to: navigation, search

Built a DVD containing:

  • video from a DV camera (high school musical)
  • slideshow (credits and slideshow) created using dvd-slideshow

I used dvd-menu to build the menu and dvd file system.

Tested the individual pieces on the computer, sounded good, looked good. Tested the dvd image on the computer - xine and totem had no problems...

Then I burned the disk and tried it on the standalone dvd player... No audio on the video, but I did get audio on the slideshows. If I changed the audio settings on the player (5.1 vs 2ch) I could reverse which parts had audio.

Did some digging - mplayer -identify is useful for debugging audio. Turns out that dvd-menu and dvd-slideshow default to 5.1 audio. (ID_AUDIO_FORMAT=8192)

The video from the camera was 2channel (ID_AUDIO_FORMAT=80)

There is a switch (-mp2) on both dvd-slideshow and dvd-menu that will force mpeg2 audio. You can also place a "ac3=0" in the slideshow .txt input file.

In my case, both the call to dvd-slideshow for the credits and the call to dvd-menu needed the -mp2 switch.
