The VideoLAN Forums

Hi,

I am developing a small application with libvlc whose purpose is to stream and record video from a webcam.

For the moment, it works fine by sound is missing.

And now, I wish to add sound. In the command line, I do:
vlc v4l2:///dev/video0 :input-slave=pulse:// --gain=0 ...

But with libvlc I can't get the :input-slave: and --gain arguments to be considered.

I tried calling libvlc_new with these 2 arguments but still no sound.

I would like to know the right way to do it. If anyone has an idea, it would be great.

Thanks in advance for help.

Nicolas.

Please share your actual code. And verbose logs.

look into libvlc_media_add_option also

Hi mfkl.

I have tried to use libvlc_media_add_option and it works with it.

Thanks for help. Now audio is working fine !
