=== DIVX (en 2 passes) : ===

==== VERSION 0.6.1 ====

<nowiki>

# Script pour faire les divx de bonne qualite generalement en 2 CD
# note: pour le debut et la fin d'encodage , il faut editer le script
# ce sera corrige dans la prochaine version ;-) J-Ch
# note : ayant eu des problemes avec les version successives de mplayer
# j'ai "arrete" la version a "0.90rc3-2.95.4"

# version 0.6.1 - 26/04/2033 - Oli (Olivier at skycode.org)
# Some bug fixing :
# 1) looping around every time something is interactively
# asked to the user to prevent the script from exiting
# and having to do the rest manually
# note : there is still some work to do on values checking

# version 0.6 - 25/04/2033 - Oli (Olivier at skycode.org)
#
# version 0.5 - J-Ch (dorian at be.linux.org)
#
# versions anterieures bulshit ;-)

# Script usage :
#
# mdivx.sh -endpos 0:00:00 -ss 0:00:00 -audiochannel 128 -xscale 640 -yscale 480
