Hi to All,

I'm trying to stream a v4l device with vlc. Everything works fine except that there's no audio. The tv-tuner audio is on the aux port. While streaming avi files there's no problem with the audio, so may be I have to tell vlc somehow to grab the audio from aux. How do I do that?

What I'm using now as a command syntax:

vlc -vvv v4l:/dev/video:adev=/dev/dsp:norm=PAL:frequency=-1:caching=300:chroma=RV32:samplerate=44100:channel=0:tuner=-1:audio=0:size=320x240:brightness=-1:colour=-1:hue=-1:contrast=-1 --sout '#transcode{vcodec=mp4v,acodec=mpga,vb=1800,ab=128,quality=1.0}:std{access=http,mux=ts}' --ttl 12

I forgot to mention:

VLC 0.8.5, Slackware Linux, MSI TV@nywhere Master, Creative Soundblaster Live Digital

I don't know what is the exact problem with this, but everything I tried seems not to work...
I have set up my alsamixer so it captures from aux. I try passing to vlc the tvnorm and etc. but it doesn't work. So I ended up with the following solution - I installed xawtv4 and setup only the channel I want to stream. I start vlc as follows:
vlc -vvv v4l:/dev/video:adev=/dev/dsp:norm=PAL-DK:frequency=191250:caching=300:chroma=RV32:channel=0:tuner=-1:audio=0:size=320x240:brightness=-1:colour=-1:hue=-1:contrast=-1 --sout '#transcode{vcodec=mp4v,acodec=mpga,vb=1536,ab=128,samplerate=44100,venc=ffmpeg{keyint=80,hurry-up,vt=800000},deinterlace}:std{access=http,mux=ts,dst=:8080}' --ttl 12 -I dummy &

It works, but without sound
After that I start xawtv with this:
xawtv -tvnorm PAL-DK &

It binds to the channel I have setup and there is a sound!

If somebody tells me how to get rid of xawtv, I will appriciate it...

Hi Muffty !

I have had the same problem. could it be that you have 2 or more sound-cards. you must disable the on boardcard in BIOS-setup or you type at the vlc command line "adev=/dev/dsp2 or 1". the clue in this solution is that the normal soundcard for linux was dsp2 in vlc and in gnome normally dsp ??
but it works.

greetings wolf

I have the same problem

Debian Linux

3x tv tuners
3x sound cards.

Three tuners work well but only 2 sound cards.

The third one connected on the aux-in input doesn't work :s

/dev/dsp and /dev/dsp2 work well
/dev/dsp1 doesn't

Any idea ?
