v4l2-adev parameter for pulseaudio?

[organesdescanales]

dear all,

i have been trying without success to get audio to work in streaming from the command line on a Ubuntu 10.04 with pulseaudio,

While i can capture the device via the GUI, leaving the setting for audio device blank, i fail to do the same from command line.

here s the start of my command:

% vlc -v v4l2:// :v4l2-vdev="/dev/video0" :v4l2-adev="/dev/audio" ...

Since vl4-adev defaults to "", i d expect that to work, but no luck either with

% ...... :v4l2-adev="" .....

Streaming audio from machines without pulseaudio is no problem.

feeling a bit stupid, and apologizing in case the solution is somewhere in this forum - and i just havent found it -
and grateful for any advice.

cheers,

sebastian

Uh?? V4L2 captures (silent) video, not audio. If you want to capture audio, you need to use the ALSA input. You can find a list of suggestions in the audio capture section of the playlist. alsa://plughw0,0.

Remy,

thank you for your answer.

However, if v4l2 is only for silent video,
what then is the

v4l2-audio-input <integer> : Card input to use for audio. default value: 0

parameter documented in the module doc, http://wiki.videolan.org/Documentation:Modules/v4l2 ?

once i know my alsa device, how do i tell vlc to use it, if not through this parameter?

thanks a lot,

sebastian

Looking at the input string with the "Show More Options" box checked in the GUI will display your default audio input like...

Code: Select all

vlc v4l2:// :input-slave=alsa:// :v4l2-standard=0

Which should work

big thanks, Greg and Remi! that works for me!

It proves that every once in a while, looking at the GUI can be helpful too.
