transcoding DVD to avi


Can anyone give me a good example command that you would use in mencoder to transcode a typical DVD to an avi file? Using say, the DivX or any popular sound codec.
(Something that will play under both windows and linux)

I find there are simply too many options to choose from and I have no idea what is good. If someone could give me a good command then I would have a basis to start from.

Having lots of problems! Any help would be greatly appreciated!

try this...

written by yours truly.
you can clearly see the resultant commands being run when it is encoding.

but a basic command would be somethign like this:
Code:
mencoder dvd://1 -ovc lavc -oac mp3lame -lameopts abr:br=128 -lavcopts vbitrate=900:v4mv:vhq:vcodec=mpeg4 -vf pp=de,scale=480:-2 -o film.avi

Using this program now: Pavtube DVD Ripper.
It converts DVD to AVI, DIVX Video, XVID Video, MPEG, WMV, MP4, MOV, 3GP, WMV, 3G2, WMA, MP3, etc.
Its advantage is that it's easy-to-use and cheap.

I would use ogmrip.

But you can also use vobcopy, then ffmpeg:

Code:
ffmpeg -i TWILIGHT_ZONE_VOL193-1.vob -b 900k -vcodec libxvid -s 640x480 -r 23.976 -aspect 4:3 -ab 128k -ar 48000 -async 48000 -ac 2 -acodec libmp3lame -threads 3 -f avi -g 300 -bf 2 camera.avi
(this is just an example I used recently)

see the documentation and adjust parameters as needed:

Actually this example seems to work better:

Code:
ffmpeg -i DVD_VIDEO1.vob -qscale 7 -vcodec libxvid -s 640x360 -r 23.976 -aspect 16:9 -ab 128k -ar 48000 -async 48000 -ac 2 -acodec libmp3lame -f avi -g 300 -bf 2 blues2.avi
I did some benchmarks and more threads = less performance, this is encoding ~2000 frames of the same movie:

Code:
1
video:5617kB audio:1320kB global headers:0kB muxing overhead 2.033539%

real	0m24.604s
user	0m24.477s
sys	0m0.093s

2
video:5654kB audio:1328kB global headers:0kB muxing overhead 2.031979%

real	0m32.787s
user	0m27.553s
sys	0m9.261s

3
video:5591kB audio:1312kB global headers:0kB muxing overhead 2.032629%

real	0m42.083s
user	0m31.680s
sys	0m25.580s

4
video:5585kB audio:1310kB global headers:0kB muxing overhead 2.032150%

real	1m25.249s
user	0m51.304s
sys	1m31.498s
So using 1 thread is the fastest.

For better quality you can use the 2 pass encoding:

Code:
ffmpeg -i DVD_VIDEO1.vob -qscale 7 -vcodec libxvid -s 640x360 -r 23.976 -aspect 16:9 -ab 128k -ar 48000 -async 48000 -ac 2 -acodec libmp3lame -g 300 -bf 2 -pass 1 -an -f rawvideo -y /dev/null
ffmpeg -i DVD_VIDEO1.vob -qscale 7 -vcodec libxvid -s 640x360 -r 23.976 -aspect 16:9 -ab 128k -ar 48000 -async 48000 -ac 2 -acodec libmp3lame -f avi -g 300 -bf 2 -pass 2 blues2.avi
