video rv24 et beamer
salut
je souhaiterai lire une video qui utilise le codec rv24
pour l'instant vlc n'est pas capable de lire la video (ecran noir)
mplayer affiche l'image a l'envers
j'insers par la suite ces vidéos dans une présentation beamer , la aussi la video fonctionne mal
sous windows, la video fonctionne avec windows media player mais pas avec vlc
dasn la presentation ça fonctionne aussi
es ce qu'un conversion de format me permettrait de m'en sortir ou bien en truvant le bon codec :?:
je viens de faire un test, si je mis avec mplayer depuis le terminal ça fonctionne bien
mais toujours pas dans ma présentation

ce sont des videos que je fabrique sous matlab au boulot
j'utilise cette fonction
http://www.mathworks.com/access/helpdesk/help/techdoc/ref/avifile.html
avec 'compresssion', 'None'
les autres codecs ne fonctionnent pas mieux
je viens de faire quelques test
impossible de convertir avec mencoder, ou bien pas trouvé la bonne technique
vraiment une galère de lire ces petites vidéo en dehors de wmp
