Bonjour,
comme vous l'aurez deviné, je cherche à numériser mes films familiaux en VHS.
J'ai récemment acquis un grabby de chez Terratec qui est directement reconnu sur fedora, pour preuve :

C'est le Device or resource busy qui me bloque... J'ai essayé avec tvtime : pareil -> Device or resource busy

En gros je n'ai pas accès à /dev/video0, quelqu'un aurai une solution ?
Le fait que lsusb voit un périphérique connecté et sache donner son nom n'implique pas que tu aies le pilote approprié pour l'utiliser.
J'ai essayé ce périphérique sur une autre machine fedora 19 :

tout fonctionne parfaitement. :-D
La différence c'est que l'une est en x86_64 (la première) et l'autre en i686.PAE. un problème de libs 32/64 ?
Je dirais que c'est un truc à remonter au bugzilla de rpmfusion.
Après update, tout fonction correctement ou presque.
Le périphérique est fonctionnelle avec mplayer, plus de soucis de ce côté là.
En revanche le matérielle ne semble pas supporter pleinement le signal SECAM !?
ou c'est peut être la commande mplayer qu'il faut affiner ?
J'ai évidement essayer de brancher mes veille consoles pour le fun et aussi pour vérifier, çà fonctionne. Mais si je dis pas de conneries çà sort en PAL ou NTSC suivant la région d’origine ?
J'ai essayer sur ma partition 7 et j'obtiens strictement le même résultat.
