The Labs - Design & Functionality For The NetHigh Quality Digital Movie Format
- Free DVD
- Players
- DeCSS
- DVD to AVI
- Authoring DVD with Open Source
During fall of 1999 a breakthrough of decrypting the DVD occured,
it was just a matter of time some skilled people
found a way to overcome that cumbersome and customer-unfriendly country-code
setting and inability to make copies of DVDs (unlike VHS, music cassettes, or
music CDs). That restrictive DVD copy-protection, along with non-support
of LINUX and *BSD provoked that de-cryption effort:
DVD-movies I consider a rip-off in Europe pricewise, in the US DVD-movies
are available for $10-$25 which is acceptable; I think the only movies
worth to buy are "Odyssey 2001", "Lawrence of Arabia", and a few others
as there the beauty of the pictures are worth the quality.
Otherwise I don't see any need for DVDs (status March 2001) until real
HDTV is coming (e.g. HDTV-720p: 1280x720, HDTV-1080i: 1920x1080), as
standard DVD comes with 720x480 only. So, DVD is an obsolete "transitional"
technology if you put aisde all the hype. "HD-DVD" might come soon
(more info in the DVD-FAQ).
A big fuss is made about the actual decss source-code, but who cares?
Note: It should be nothing illegal of having a program able to
convert your legally bought DVD into an uncrypted format, and even make
copies for your own; illegal is when you copy your DVD for others.
The funniest way (posted on /. and DeCSS Gallery) to retrieve the decss source-code goes this way
|
dig @138.195.138.195 goret.org. axfr | grep '^c..\..*A' | sort |\
|
|
cut -b5-36 | perl -e 'while(<>){print pack("H32",$_)}' | gzip -d
|
Best use mplayer, which includes mencoder, to convert a DVD proceed like this:
DVD Disk:
|
mencoder -dvd 1 -ovc lavc -lavcopts vcodec=mpeg4:vhq:vbitrate=1000 -oac copy -vop scale -zoom -xy 720 -o my_movie.avi
|
Instead of -dvd 1 use 2, 3 etc to select the correct title-id, you can also use -dvd 1-4.
VOB Files:
|
mencoder -ovc lavc -lavcopts vcodec=mpeg4:vhq:vbitrate=1000 -oac copy -vop scale -zoom -xy 720 *.VOB -o my_movie.avi
|
Best first try with mplayer to play the *.VOB files, if you get commentary audio track instead of the original
audio track, use -aid 128 (128-159) until you got the correct track.
