Installation de la libcec4 pour hdmi-CEC

**boomfaar** · 06/07/2017, 09h59

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 :

Sélectionner tout - Visualiser dans une fenêtre à part

 echo "scan" | cec-client -s

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

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 :

Sélectionner tout - Visualiser dans une fenêtre à part

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 :

  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,

Bonjour,

Pouvez-vous me rappeler ce qu'est sensé faire le "tx 10 82" ? Je vois dans le log que vous donnez, que la télévision est en "on" (donc allumé). Il ne semble pas y avoir d'autre erreur.
~~Pour le problème avec libcec4, il faut lancer le programme en root.~~
Pour l'erreur de compilation :

/home/admin/libcec/src/cecc-client/cecc-client.c : In function 'cec_process_console_command' :
/home/admin/libcec/src/cecc-client/cecc-client.c:384:3: internal compiler error: Erreur du bus
if (strncmp(buffer, "q", 1) == 0 || strncmp(buffer, "quit", 4) == 0)

C'est une erreur interne du compilateur. C'est "inquiétant" dans le sens, ce n'est pas une erreur de code. Le compilateur a planté tout seul. Ne corrigez pas un tel code, car d'une : ça ne marchera sûrement pas à la fin, de deux, vu l'erreur, elle risque de se produire deux lignes plus loin.
Peut être avec un "make" sans l'option j4, ça passe. Peut être que la machine qui compile (j'imagine le mini PC) n'est pas assez puissant ? (du coup, viser la cross compilation). Peut être il manque de la mémoire ?

Le TODO peut aussi être un oubli, mais en effet, ça ne semble pas fini (libcec n'a pas de mode dynamique).

Bon courage

Bonjour,
Déja, merci de prendre du temps a répondre a mes questions

Donc oui on voit bien que quand on lance cette commande la TV passe active, mais j'ai l'impression qu'elle repasse en mode non active car quand je lance la commande scan, j'obtiens ceci :

Oui je n'avais pas l'intention de retoucher le code pour le faire marcher. J'ai réessayer avec juste make, j'ai exactement la même erreur qui se produit.
Pour la puissance du mini pc, voici quelques détails :

Donc je pense que ca peut le faire tourner, et voici les informations pour la mémoire :

Elle repasse en inactive, car le client quitte juste après l'exécution de la commande. Pour que cela soit persistent, il faut lancer et laisser tourner cec-client. Ensuite, vous pouvez utiliser "as" afin de rendre la source active et vous pourrez ainsi travailler.

Pour la compilation, est-ce que tous vos paquets sont à jour ?

**boomfaar** · 10/07/2017, 15h18

J'ai lancé un petit update pour mettre tout à jour, et j'ai retenter de compiler et je suis tombé sur le même problème.
Sinon je comprend mieux du coup pour cec-client

Mais du coup voila ce que ca donne :

Donc le fait de faire "as" rend le CECTester en active source, du coup après je lance la commande :
tx 10 82 (Je suis aller sur ce site http://www.cec-o-matic.com/ j'ai mis comme source recording 1 et comme destination TV, j'ai cliqué sur One Touche play, sélectionner Active Source, et mis comme adresse : 0.0.0.0 et ca ma rendu çà) pour pouvoir rendre la tv actif.

Je ne sais pas si j'ai bien exprimer mon problème, mais je cherche juste à switcher entre la tv classique, et le mini pc, donc je pense que c'est la bonne commande, mais la plupart du temps a la suite de celle-la j'obtiens un waiting for input......

Bon après quelques recherche, il me semble que ce que je veux faire n'est pas possible. Ce n'est simplement pas inclus dans la librairie CEC de passer de HDMI 1 à la tv interne.

Voulez-vous dire, changer la source ?

**boomfaar** · 17/07/2017, 09h04

Oui tout a fait

**boomfaar** · 20/07/2017, 11h02

Pensez-vous que c'est possible de changer de source via une commande ? car il me semble que dans la librairie hmdi cec il n'est pas possible de faire ca, ou du moins je n'ai pas trouvé comment faire....

**LittleWhite** · 21/07/2017, 16h56

Avec

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

echo h | cec-client -s -d 1

Vous pouvez obtenir la liste des commandes CEC disponibles.

En effet, il n'y a pas de commande pour changer de source sur la télévision. J'étais pourtant sur d'avoir réussi cette opération lors de l'écriture du tutoriel
