method to create a menuless DVD

Happy 2008, everybody!

I keep forgetting the commands to create and burn DVD-ready files from Cinelerra. As the following commands worked well for me, I thought I'd write 'em down for folks. I won't concentrate on creating the DVD-ready file, but more on the latter steps using dvdauthor and burning an iso.

In order to get a working DVD, you're going to do the following:
1 - from Cinelerra, create a valid DVD-ready MPEG file
2 - with dvdauthor, create a DVD filesystem from that MPEG
3 - with dvdauthor, create a table of contents for the DVD filesystem
4 - with mkisofs, create a DVD-ready ISO image in prep for burning to DVD
5 - with growisofs, burn the DVD

PrerequisitesCinelerra
mplex
dvdauthor

1 - Create a valid DVD-ready MPEG file
In Cinelerra, create a project with the following specs:
Audio
Samplerate: 48000
Channels: 2

Video
Framerate: 29.97
Width: 720
Height: 480
W/H Ratios both 1
Color Model: YUVA-8bit
Aspect Ratio: 3:2 or check Auto
Interlace Mode: Not Interlaced

Render Options
Audio
File Format: MPEG Audio
Layer: II
Kbits per second: 384Kbps

Video
File Format: YUV4MPEG

Either mpeg2enc or ffmpeg presets should work. Just make sure the aspect ratio of the resultant video is 16:9, because dvdauthor will not create the DVD filesystem if this is not the case. The switch to ffmpeg is "-aspect 16:9" or "aspect 1.777" like so:
ffmpeg -f yuv4mpegpipe -i - -y -target dvd -aspect 1.777 -f mpeg2video %

Since multiplexing to DVD-ready file in ffmpeg doesn't work as expected, I combine the audio and video with MPLEX using this command:
mplex -f 8 -o test.mpg video.m2v audio.mp2

I will try to figure out the source of the ffmpeg issue later.

2 - Create a DVD filesystem from MPEG
Using dvdauthor, run this command to create a filesystem in a folder called "dvd" from your test mpeg:
[mule@ogre ~]# dvdauthor -o dvd/ -t test.mpg
DVDAuthor::dvdauthor, version 0.6.14.
Build options: gnugetopt iconv freetype fribidi
Send bugs to

INFO: dvdauthor creating VTS

STAT: Processing test.mpg...

INFO: Video pts = 0.133 .. 598.564

STAT: fixed 1499 VOBUS


3 - Create a Table of Contents
Using dvdauthor, run this command to create a table of contents for the DVD filesystem:
[mule@ogre ~]# dvdauthor -o dvd/ -T
DVDAuthor::dvdauthor, version 0.6.14.
Build options: gnugetopt iconv freetype fribidi
Send bugs to

INFO: Scanning dvd/VIDEO_TS/VTS_02_0.IFO
INFO: Scanning dvd/VIDEO_TS/VTS_03_0.IFO
INFO: Scanning dvd/VIDEO_TS/VTS_04_0.IFO


4 - Create a DVD-ready ISO image for burning
Using mkisofs, create an ISO image:
[mule@ogre ~]# mkisofs -dvd-video -o dvd.iso dvd/
I: -input-charset not specified, using utf-8 (detected in locale settings)
Unknown file type (unallocated) dvd/.. - ignoring and continuing.

Here's nice tip on testing your ISO by mouting it from your filesystem:

5 - Burn the ISO image to a DVD
Using growisofs, burn the ISO image to a DVD. Note that I used this command on a DVD RW:
[mule@ogre ~]# growisofs -dvd-compat -Z /dev/dvd=dvd.iso
Executing 'builtin_dd if=dvd.iso of=/dev/dvd obs=32k seek=0'
/dev/dvd: "Current Write Speed" is 2.0x1352KBps.

Appendix
Formatting a DVD RW
Using dvd+rw-format, format your DVD RW media:
[mule@ogre Desktop]# dvd+rw-format -f /dev/dvd
* BD/DVD±RW/-RAM format utility by , version 7.0.
* 4.7GB DVD-RW media in Restricted Overwrite mode detected.
* formatting 29.2/


That's it. Happy New Year!
The Mule
