piti�, pour ne laisser que � vlc �, � gvlc � (gnome) et � fbvlc �
(framebuffer) ; les autres restent bien entendu accessibles avec
par exemple � vlc --vout ggi �.
. IMPORTANT - nouvelle option --synchro pour forcer un type de
synchro. Pour le moment les options possibles sont :
--synchro I /* n'affiche que les I */
--synchro IP /* affiche les I et toutes les P */
--synchro IP+ /* affiche les I, les P, et la moiti� des B */
--synchro IPB /* affiche toutes les images */
Toute autre valeur de --synchro sera ignor�e et c'est l'algo
par d�faut bas� sur la consommation de processeur qui sera
utilis�. Notez que si vous en demandez trop au vlc, il va
bien entendu planter, ou tout du moins remplir sa fifo comme
un gros cochon. On n'y peut pas grand chose, c'est la vie.
