Bonjour,

Je cherche a "streamer" le son provenant de mon raspberry sur le reseau afin de pouvoir le r�cup�rer sur une autre machine.
Apr�s avoir parcouru le net, je suis tomb� sur trois m�thodes qui me posent le m�me probl�me.

Code :

S�lectionner tout - Visualiser dans une fen�tre � part

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

Code :

S�lectionner tout - Visualiser dans une fen�tre � part

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

Code :

S�lectionner tout - Visualiser dans une fen�tre � part

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 probl�me.
Mais pour streamer le micro pas moyen...

le vlc me ressort une erreur

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

Et avec avconc et ffmpeg

cannot set parameters (Input/output error)

Et pour info:

Bonjour,

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

Essaye la commande

Code :

S�lectionner tout - Visualiser dans une fen�tre � part

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

[kevinrolinbe]

En faite, j'ai d�ja test� un peu pour changer ces parametres...
Ex:
hw:1,0
hw:0,0
hw:1
hw:0

A chaque fois:

Code :

S�lectionner tout - Visualiser dans une fen�tre � part

Bonjour,

V�rifiez la pr�sence des r�pertoires /dev/snd/*, /dev/dsp*, et /dev/audio*

S'ils existent, testez la commande pass�e en SUDO ?

Code :

S�lectionner tout - Visualiser dans une fen�tre � part

 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 v�rifier les permissions de /dev/snd/*, /dev/dsp*, et /dev/audio* ?

Le probl�me pourrait se situer dans ces permissions. Alsa ne peut pas acc�der au fichier correspondant au device. Cela est donc peut �tre une question de droits du compte avec lequel vous passez votre commande.

Je vois l'id�e, j'avais d�ailleurs il me semble d�j� test�, mais quand vlc refuse de s�ex�cuter en sudo, c'est plus compliqu�.

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).
