For a project we have going at Oasis Digital, we have explored various libraries for creating video DVDs from computer-generated content until program/script control. There are quite a few ways to do this; one that is appealing for a command-line junkie is the combination of ffmpeg, dvdauthor, and mkisofs. It took considerable research to figure out what commands to string together for a simple scenario:
- you have some video in AVI format (for example, an MJPEG AVI from a DV video camera)
- you have some background music in mp3 format
- you want a simple one-title one-chapter DVD with that video and audio
There are plenty of sites with long and complex sets of commands to accomplish these things. But for this simplest case, the essential commands are:
ffmpeg -y -i video.avi -i audio.mp3 -target ntsc-dvd -aspect 4:3 dvd.mpg
dvdauthor -x file.xml # there is a way to avoid the file by putting a few more options here
mkisofs -dvd-video -o dvd.iso DVD
Of course, there is considerable other work involved in wiring up a full solution, but that is more project specific. I hope these example commands shorten the research time for the next fellow who needs to do this core processing.
