Automated DVD production
From Organic Design wiki
It would be nice to generate DVD discs from video files or cameras in a simple automated way.
Video specs
- mpeg2 av muxed stream
- Bit rate from 4Mb/s - 10 Mb/s
Audio specs
- mpeg1-layer2
- AC3
- PCM
- Must be 48kHz sample rate
Input
- A directory of video files numbered to indicate their order
Output
- A DVD image file, or
- A finished DVD if the machine has a DVD writer
Packages
apt-get install debian-multimedia-keyring dvdauthor mjpegtools imagemagick toolame
tovid
High level python scripts that tie it all together - probably won't need the make file any more.
Makefile
Here is the basis of a Make file that will eventually perform the whole process from file encoding to burning. It does not work at the moment, but is well documented.
