By now, you should have
assembled a script file in
PPML format,
encoded the video into an mpeg video file (in our example,
output.m2v), and
extracted the audio to a
separate file (audio.ac3 in our example). The next step is to
combine the audio and video tracks into a single mpeg file, using
mplex from the mjpegtools suite:
mplex -f 8 -M -V -o output-%d.mpg output.m2v audio.ac3
By default, mplex will split up files into chunks that are no
larger than 2GB. In the above example, the chunks will be saved as
output-1.mpg, output-2.mpg, etc. This behavior is an
outdated defensive tactic intended to protect against systems with
inadequate support for large files. Since modern linux is not
such a system, it is recommended to recombine the files into one large
output.mpg file to simplify the next step:
cat output-*.mpg > output.mpg
Find or make a directory with lots of free space (such as
/dvd), and run the following series of commands from the
dvdauthor suite:
dvddirgen -o /dvd
dvdauthor -o /dvd -a ac3+ja output.mpg
dvdauthor -o /dvd -T
ac3 with mp2 or pcm if your audio track is one
of these formats, and replace ja with the two letter language
code of the actual language used in the audio track (en for
English, ja for Japanese, fr for French, de for German,
and so on).
There are two ways to create a DVD having multiple chapters. The
simplest is to give multiple MPEG files on the dvdauthor command
line, e.g.:
dvdauthor -o /dvd -a ac3+ja output1.mpg output2.mpg output3.mpg output4.mpg
H:MM:SS.SS times to
dvdauthor using the --chapter flag, e.g.:
dvdauthor -o /dvd -a ac3+ja --chapter 0:24:36.52,0:48:15.98,1:12:42.10 output.mpg
Make an ISO filesystem:
mkisofs -dvd-video -udf -r -o /dvd.iso /dvd
and burn it using dvdrecord if you have a DVD-R drive:
dvdrecord -v -dao -speed=4 -dev=0,0,0 -driveropts=burnproof /dvd.iso
or using growisofs if you have a DVD+R drive:
dvd+rw-format -f /dev/scd0
growisofs -Z /dev/scd0=/dvd.iso
You're done. Enjoy!
