Anyone here have much experience with dvd-author and/or dvd-slideshow
I am having a few problems with both (at the moment I am driving them from qdvdauthor, but the same issues seem to be present even if I do it from the command line)
I am trying to add background music (in the form of an mp3 file) to the VMGM menu (main menu)
I am trying to (or at least qdvdauthor is trying to) do the following mplex -f 8 -o "menu.mpg" "menu.m2v" "song1.mp3"
Where the m2v file is a MPEG2 stream of my menu background, the mpg file is the output that goes into DVD author and song1.mp3 is the music I want.
At this point I get ERROR:[mplex] File song1.mp3 unrecogniseable!
mp3 file is a straight 192kbs file that seems happy enough in any player I chuck it through.
Hi Wayne,
It seems the audio can't be MP3, MP2 would probably work. From the HOWTO I gave you a while ago, ac3 files should work.
Create some background audio for the menu: Code: ffmpeg -i your_music_file.mp3 -f wav menu_audio.wav
Use 'normalize' to make audio softer/louder if necessary: Code: normalize -a -10dB menu_audio.wav
Convert to AC3 audio: Code: ffmpeg -i menu_audio.wav -ab 224 -ar 48000 menu_audio.ac3
If you do not want any audio present in your menu, it is still necessary to create a silent audio file for mplex so the DVD menus will work correctly. Like this: Code: ffmpeg -ab 224 -ar 48000 -ac 2 -t 5 menu_audio.ac3
Merge background menu video/audio: Code: mplex -f 8 -o matrix_menu.mpg matrix_menu_background.m2v menu_audio.ac3
