Lecture & Capture Video

Un ordinateur Pentium4 2,6 ghz en dual boot Precise Pangolin / XP, équipé d'une carte TV MIRO Pro (TV, Composite et SVideo) et une liaison avec le caméscope par Cable SVIDEO ( le camescope est relié par un adaptateur peritel qui dispose d'une sortieTV , une composite et une SVideo)

Après des essais infructueux pour installer xdtv et suite aux conseils reçus sur le Forum je me tourne vers d'autres solutions

Avec VLC/Periph de Capture, je ne peux utiliser que /dev/video0, qui ne me donne aucun résultat : j'avais cru comprendre (dans la Documentation sur Internet que dans le schéma de liaison dont je dispose , l'entrée Svideo de ma carte était /dev/video2 ???, mais je n'ai aucun moyen de forcer cette référence . En outre, à l'ouverture de vlc j'ai les messages suivants :

Avec mencoder , dans la nombreuse Doc que j'ai lu je n'ai pas trouvé comment lire et encor moins capturer le signal à partir de l'entrée SVideo

Merci d'avance pour toute aide
