Bonjour,

je viens de réaliser un player semblable à celui-là, qui fonctionne très bien, mais il me reste un petit problème :
Quand la vidéo tourne, les déplacements du slider son pris en compte. Mais quand elle est en pause, l'affichage ne s'actualise plus! Il faut obligatoirement refaire play pour que la vidéo saute d'un coup, c'est moche.

Comment faire pour que l'affichage de la vidéo se mette à jour même quand elle est en pause??
J'ai déjà essayé repaint() et validate(), tous les deux sans succès...

Merci à tous.

il te manque un codec ou ce code ne marche pas. Essaye avec une autre video compressée avec un autre codec.

ok, je verai aussi cet week end ce que ça va donner avec le passage de paramètres.

Je t'envoie les modifications que j'ai essayé pour la transforamtion en applet. ça ne marche pas pour le moment.

Tout d'abord vu que la méthode main peut recevoir des éléments args, il semble possible lors du lancement du jar exécutable de filer des paramètres. En le lançant avec un .bat ou un .sh par exemple.
Fais des sytem.out .println(args[n]) , tu verras les arguments passés en ligne de commande.

Ensuite pour le problème de transformer le code en applet je vais le faire ce week end.Si le code à évolué envoie le moi par mail comme çà tu auras la meilleure mise à jour possible.

J'ai essaye de faire un .jar executable, j'ai reussi mais je suis oblige de mettre l'adresse complete des images et de la video...donc mon .jar executable ne fonctionne que sur mon ordi forcement...Si je laisse
("videoPlayer/video/open.avi" ).setVisible( true );
comme on le trouve dans le main, le fichier de la video n'est pas trouve... j'ai essaye de mettre ./ ou ../ devant "videoPlayer" mais ca marche pas plus... est ce que qq'1 a reussi a resoudre ce probleme ?

Oui j ai une solution relativement facile et élégante:enfin je pense ...
tu fais un fichier jar avec le java mais tu transforme le java de maniere a ce que ce soit une applet qui prend comme parametre le nom du fichier et voila le tour est joué je le ferais ptet si j ai le temps et que tu sais pas comment faire sinon bon courage.
Le click permet de recharger la page avec la video insérée sous forme d 'applet paramétrée avec le nom sur lequel tu as cliqué.

Comment ( "java nomdufichier")? comme appelle d'un module externe? 'avec (exec (java nomdufichier))? mais pour ça, il faudra que la commande java soit reconnu.

en fait moi je suis sous linux et je travail avec le serveur apache. Mon souci est de permettre à partir d'un clik sur un nom de video(sous forme de lien) le document video joue dans le player.

Avez vous une solution pour ça?

19 juil. 2004 à 19:30
oui c possible, il suffit de creer à partir de ce fichier un exe et de le lancer par l intermédiaire de php en demarrant un processus qui demarrera le fichier java(on peut meme le lancer en lancant "java nomdufichier" depuis php).
On peut envisager aussi l'autre sens et lancer un fichier en php depuis le java à condition de posseder un serveur php.
Il faudrait que tu detailles ce que tu voudrais faire exactement à partir de ce fichier java.

Bon ben voila je te livre le fichier corrigé avec un thread en plus pour bouger la barre ca a l air de marcher mais c de l approximatif , je debute en multithread.
C est aussi de l approximatif pour la barre de scroll qui ne devrait pas etre la representation exacte de la longueur du film mais plutot d'un multiple de cette longueur afin de faire un entier sinon la derniere seconde risque de ne pas etre représentée sur la barre enfin bon tu me diras c pas si grave.
Parfois il arrive des erreurs mais non bloquantes.
