Bonjour,

Je cherche à développer une petite application permettant de visualiser un flux vidéo. J'ai trouvé un code sur internet qui donne ceci :

/*********tuto_vlc.cpp**********/

#include "tuto_vlc.moc"

ce code nessecite egalement d'utilisé (je n'ai pas compris à quoi sert se point pro????)

/********* tuto_vlc.pro ********************/

jusque la sa marche mais la ou je bloque c'est pour intégrer ceci a mon programme créé avec Kdevelop

Mais la j'ai les 3 erreurs suivante :

/home/rom/player/src/player.h:10: error: 'libvlc_exception_t' does not name a type
/home/rom/player/src/player.h:11: error: ISO C++ forbids declaration of 'libvlc_instance_t' with no type
/home/rom/player/src/player.h:11: error: expected ';' before '*' token

Quelqu'un a une idée pour corriger les erreurs ?

/home/rom/player/src/player.h:10: error: 'libvlc_exception_t' does not name a type

Il ne trouve pas ce qu'est libvlc_exception_t dans player.h.
Il ne te manque un include? Utilise tu un pointeur?
C'est ce .h qu'il aurais fallu montrer ;)

merci yan

voila le point h en question

la ligne
#include <vlc/libvlc.h>
doit être dans le fichier player.h puisque la déclaration de ta classe player en a besoin.

En effet je me suis trompé sur l'endroit ou j'ai placé l'include.

Mais il me retourne d'autre erreurs :

player.o: In function `player::playFile(QString)':
/home/romain/player/src/player.cpp:30: undefined reference to `libvlc_playlist_add'
/home/romain/player/src/player.cpp:32: undefined reference to `libvlc_playlist_play'
player.o: In function `player':
/home/romain/player/src/player.cpp:12: undefined reference to `libvlc_new'
/home/romain/player/src/player.cpp:18: undefined reference to `libvlc_video_set_parent'
/home/romain/player/src/player.cpp:12: undefined reference to `libvlc_new'
/home/romain/player/src/player.cpp:18: undefined reference to `libvlc_video_set_parent'

Ces erreurs veulent dire que la librairie vlc manque à l'édition de liens.
Avec Qt si on utilise qmake c'est à ajouter dans la ligne LIBS du fichier projet (le .pro)
Qqch du genre

Code:

---

1 2	LIBS += -lvlc

---

Oui je me doutais que l'équivalent du fichier /* tuto_vlc.pro */ était nècessaire mais je ne sais pas quel fichier de mon projet je dois modifier



/********* tuto_vlc.pro ********************/
SOURCES += tuto_vlc.cpp
LIBS += -lvlc
