Installation de la libcec4 pour hdmi-CEC
Bonjour a tous,
Un petit message de détresse sur l'utilisation de la libcec non pas pour un Raspberry mais pour un mini pc et une tv toshiba regza.J'ai trouvé un article du 26 janvier 2017 très bien fait, qui parle de tout ce qu'on voudrait savoir sur la libcec et l'utilisation de l'hmdi cec ( http://alexandre-laurent.developpez....-cec/#LIII-B-2 ).
Je suis en train de developper une application web qui pourrait permettre de faire des appels videos depuis une télévision.
Lorsque je lance des commandes pour faire des tests, les commande
Code:
echo "scan" | cec-client -s
Code:
echo "standby 0" | cec-client -s
marche bien, mais dès que j'essaye d'envoyer des valeurs, comme par exemple pour passer la TV en mode active par exemple
Code:
echo "tx 10 82" | cec-client -s
voici ce qu'il me rend :

Donc je me suis dis que ca venait peut etre de la version de libcec, j'utilise actuellement la libcec3.0.1 .
Je suis donc partie dans l'idée d'installer la libcec4 en suivant votre article dans la rubrique "III-B-2-a. Installation".
Mais quand je lance make -j4 une erreur intervient :
Code:

if (strncmp(buffer, "q", 1) == 0 || strncmp(buffer, "quit", 4) == 0)

Quand je vais voir le code sur github, voici la fonction :

static int cec_process_console_command(const char* buffer)
{
size_t buflen;
buflen = strlen(buffer);
if (strncmp(buffer, "q", 1) == 0 || strncmp(buffer, "quit", 4) == 0)
return 0;
cec_process_command_as(buffer) ||
cec_process_command_scan(buffer);
//TODO
return 1;
} |
Je vois le petit TODO qui veut bien dire que la fonction n'est pas encore faite :p .
Est il possible d'ignorer cette fonction ? , car du coup l'installation de la libcec4 échoue.
Ma priorité serait de pouvoir lancer une commande pour switcher entre la box, et la tv, et la tv à la box.
Voila, j'espère avoir été assez clair sur mon problème en espérant que vous pourrez me venir en aide.
Cordialement,
Jules PAGET
