# encode2mpeglight is a program that can create VCD/SVCD/DVD mpegs
|
|
# and eventually extract VobSub subtitles from a DVD using only
|
|
# MEncoder/MPlayer.
|
|
#
|
|
# encode2mpeglight is a stripped release of encode2mpeg and therefore the
|
|
# code is redundant in several places, with many variables defined and
|
|
# used for no apparent reason. This cannot be avoided easily.
|
|
# A command line like:
|
|
# encode2mpeglight <encode2mpeglight options>
|
|
# will produce almost the same results as:
|
|
# encode2mpeg -mpeg -mpegonly <encode2mpeglight options>
|
|
#
|
|
# If you need more features like:
|
|
# - two or more audio streams, chapters, subtitles, menu
|
|
# - creation, burn and verification of the disk image
|
|
# - creation of MPEG-4 avi and subtitles for a hardware player
|
|
# and more, consider to use the full release (http://encode2mpeg.sf.net)
|
|
#
|
|
# encode2mpeglight is mainly tested with the stable release of MPlayer,
|
|
# I try to make it work with CVS too, but due to the "instable" nature of
|
|
# CVS, bugs may suddenly appear. If you find any, please report it to me.
