dvdauthor is a program that will generate a DVD movie from a valid
mpeg2 stream that should play when you put it in a DVD player.
To start you need mpeg files that contain the necessary DVD VOB
packets. These can be generated by passing '-f 8' to mplex. See the
included utility makevob.
There are 3 steps to building the DVD directory structure on your HDD.
1. Delete a previously authored dvd
dvddirdel [-o dir]
WARNING! This will delete without discrimination the contents of
the directory that you specify!
2. Create your titlesets
dvdauthor [-o dir] [audio/video/subpicture options] [chapters]
To create 1 chapter per mpeg, simply do
dvdauthor [-o dir] [a/v/s options] chap1.mpg chap2.mpg chap3.mpg...
To manually specify chapters, use the '--chapters' option
dvdauthor [-o dir] [a/v/s options] -c chap1a.mpg chap1b.mpg -c chap2a.mpg chap2b.mpg ....
To add chapters every fifteen minutes, do
dvdauthor [-o dir] [a/v/s options] -c 0,15:00,30:00,45:00,1:00:00,1:15:00... longvideo.mpg
Call dvdauthor for each titleset you want to create. Note that
due to the DVD standard, all audio, video, and subpicture options
must be set once for the entire titleset; i.e. you cannot mix pal
and ntsc video in the same titleset. For that you must generate
separate titlesets.
Run dvdauthor -h to see the audio, video, and subpicture options.
Note that dvdauthor can autodetect most parameters except the
language.
3. Create the table of contents
dvdauthor -T [-o dir]
Viola! You now have a DVD directory structure that will probably
work! You can now write this out to your DVD, mini-DVD (CD), or just
play it from your HDD. To generate the UDF image to burn to DVD, use
mkisofs from cdrtools-1.11a27 or later. Simply pass it the -dvd-video
option.
BTW, if you have an old HDD that you use for generating dvd images,
you can create /usr/local/etc/dvdauthor.conf or ~/.dvdauthorrc and add
the line:
WORKDIR=foo
Then you won't need to specify -o to dvddirgen or dvdauthor.
Alternatively, you could just set
WORKDIR=mydvd
to always have it create a DVD in the current working directory.
