Stream audio - Alsa cannot set parameters (Input/output error)

Bonjour,

Je cherche a "streamer" le son provenant de mon raspberry sur le reseau afin de pouvoir le récupérer sur une autre machine.
Après avoir parcouru le net, je suis tombé sur trois méthodes qui me posent le même problème.

Code:

cvlc -vvv alsa://hw:1,0 --sout '#transcode{acodec=mp3,ab=128}:standard{access=http,mux=ts,dst=:1234}'

Code:

avconv -f alsa -ac 1 -i hw:1,0 -acodec libmp3lame -ab 64k -f rtp rtp://127.0.0.1:1234

Code:

ffmpeg -re -f alsa -i hw:1,0 -acodec mp2 -ab 192000 -ar 44100 -ac 1 -filter 'bandpass=f=1000:csg=0:width_type=q:w=.806' -f rtp rtp://127.0.0.1:1234

Avec la solution vlc, j'ai pu stream un fichier mp3 sans problème.
Mais pour streamer le micro pas moyen...

le vlc me ressort une erreur

Citation:

core input error: open of `alsa://hw:1,0' failed

Et avec avconc et ffmpeg

Citation:

cannot set parameters (Input/output error)

Et pour info:

Bonjour,

A la vue des config postées, il me semble que le device alsa est 0, or dans ta commande VLC tu appelle le subdevice 0 de la carte 1, d’où l'erreur.

Essaye la commande

Code:

cvlc -vvv alsa://hw:0,0 --sout '#transcode{acodec=mp3,ab=128}:standard{access=http,mux=ts,dst=:1234}'

En faite, j'ai déja testé un peu pour changer ces parametres...
Ex:
hw:1,0
hw:0,0
hw:1
hw:0

A chaque fois:

Bonjour,

Vérifiez la présence des répertoires /dev/snd/*, /dev/dsp*, et /dev/audio*

S'ils existent, testez la commande passée en SUDO ?

Code:

sudo cvlc -vvv alsa://hw:0,0 --sout '#transcode{acodec=mp3,ab=128}:standard{access=http,mux=ts,dst=:1234}'

Si cela fonctionne normalement, il vous faut vérifier les permissions de /dev/snd/*, /dev/dsp*, et /dev/audio* ?

Le problème pourrait se situer dans ces permissions. Alsa ne peut pas accéder au fichier correspondant au device. Cela est donc peut être une question de droits du compte avec lequel vous passez votre commande.

Je vois l'idée, j'avais d’ailleurs il me semble déjà testé, mais quand vlc refuse de s’exécuter en sudo, c'est plus compliqué.

Citation:

VLC is not supposed to be run as root. Sorry.
If you need to use real-time priorities and/or privileged TCP ports
you can use /usr/bin/vlc-wrapper (make sure it is Set-UID root and
cannot be run by non-trusted users first).

J'ai édité mon message...

Vérifiez la présence et les droits des répertoires que je vous ai indiqué

Après verification, seul le dossier /dev/snd existait.
J'ai créé les deux autres, modifier les droits mais toujours la même erreur.

Je pense retenter une installation mais je ne sais pas ce qui vraiment nécessaire

Effectivement, le plus simple est de commencer par une install propre.

Pour cela, vous pouvez :

Code:

sudo apt-get --purge remove linux-sound-base alsa-base alsa-utils

qui désinstalle et purge la config précédente. puis :

Code:

sudo apt-get install linux-sound-base alsa-base alsa-utils

Attention il me semble que cette install, sous Ubuntu supprime quelques paquets qu'il faudra réinstaller avec

Code:

sudo apt-get install gdm ubuntu-desktop

Après un redémarrage, la commande :

Code:

aplay -l

doit normalement lister la carte.

Il faudra ensuite configurer alsamixer. Depuis un terminal

Code:

alsamixer

L'interface se lance, on peut effectuer les réglages. Une fois terminé, il est possible de sauvegarder les réglage afin de les reprendre systématiquement. Cela se fait avec

Code:

sudo alsactl store 0

Bon je viens de tout résintaller sur une nouvelle sd en suivant tes indications...

Et ça marche !!!

Je suppose qu'a force de faire des tests dans tous les sens, j'ai du dégommer des paramètres :/

Enfin le principal est la, le son transit correctement !!!

Merci beaucoup à toi !
