MEncoder can encode from files or directly
from a DVD or VCD disc.
Simply include the filename on the command line to encode from a file,
tracknumber to encode
from a DVD title or VCD track.
If you have already copied a DVD to your hard drive (you can use a tool
such as dvdbackup, available on most systems),
and wish to encode from the copy, you should still use the
dvd:// syntax, along with -dvd-device
followed by the path to the copied DVD root.
The -dvd-device and -cdrom-device
options can also be used to override the paths to the device nodes
for reading directly from disc, if the defaults of
/dev/dvd and /dev/cdrom do
not work on your system.
When encoding from DVD, it is often desirable to select a chapter or
range of chapters to encode.
You can use the -chapter option for this purpose.
For example, -chapter
will only encode chapters 1 through 4 from the DVD.
This is especially useful if you will be making a 1400 MB encode
targetted for two CDs, since you can ensure the split occurs exactly
at a chapter boundary rather than in the middle of a scene.
If you have a supported TV capture card, you can also encode from the
the filename, and -tv to configure various capture
DVB input works similarly.
