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.
dvd-slideshow
I am running the command dvd-slideshow -o show -f list.txt -n Photos list.txt is a test file with entries as follows
imgp1364.jpg:5:: imgp1365.jpg:5:: and so on....
When I run this I get the following in the output messages
[mpeg2enc] Could not read YUV4MPEG2 header: stream requires unsupported features!
Any help offered would be greatly appreciated.

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

Cheers Chris, I was thrown slightly by qdvdauthor only accepting mp3 or wav files and rejecting ac3 files. It seems that there is a step missing in the scripts that qdvdauthor generates (namely the step that does the ffmpeg conversion) Also the man page for mplex sort of suggests that it should accept mp3 audio files.
I think after using qdvdauthor a bit that I should have paid more attention to you and done it your way :-)
Also I have solved the dvd-slideshow problem by modifying the dvd-slideshow scripts to add -S 420mpeg2 to every instance where ppmtoy4m is called.
Have you tried creating menus yet?
Took me ages last time I tried using the Gimp to do it. Ended up with a slightly distorted menu as I told dvdauthor it was 16:9 when it should be 4:3 DOH! :-)

That was the bit that I really needed qdvdauthor's help for, now I have seen the output xml I think I have enough understanding to do it by hand.
I was failing to understand how the option highlighting worked and how to define submenus, still haven't worked out how to do a fancy menu transition (where it will play a short transition mpeg as you change to a submenu) but I am getting there.
The main problem with doing this stuff is the constant rebuilding of the DVD structure to test stuff like the menus, I have streamlined this process a bit by putting placeholder 2 frame snips in where the real footage should be.

Yeh doing stuff for TV does that to you, careful choice of fonts is also required as it is easy to forget what poor resolution does to small typefaces...also been caught out once today by dvd-slideshow defaulting to NTSC output.
Do you know how much different (hardware) players drift from spec (beyond some not liking some recordable media) If my menus and transitions and stuff all work on player A then it is reasonable to assume that it is likely to play on all players (remembering early versions of Xine DVD-NAV not liking some disks here) ?

Yep I know all about doing stuff for TV. I'm the nightshift engineer looking after BBC1 at the moment :-)

Some players are not very tolerent of some MPEG2 clips. I've found that some DVB mpeg2 will not play on cheaper players. I put the first 4 episodes of Lost onto DVD, which my 5 year old Panasonic player was fine with, but my parents Cyberhome player had massive lip sync errors.
I'm going to keep fighting with doing menus. After I've done it a few times, I think I might be able to get it right!
