The VideoLAN Forums

Hy !
I'm working on an encoding server project, using a Debian OS and a Osprey 210 card.
Newbie on video application under *nix plateform, i don't understand about devices etc...

I've try that command "successfully":
vlc -vvv --color v4l:/dev/video:norm=pal:frequency=543250:size=vga:channel=0:adev=/dev/audio:audio=1 --sout '#transcode{vcodec=mp4v,vb=512,scale=1,acodec=mpga,ab=96,channels=2,deinterlace}:std{access=http,mux=asf,url=:8080}'

-> With this, I can watch the video, but there's no sound...

I'm using RCA input stereo of the Osprey 210 card, but i don't know what device use...
adev=/dev/audio:audio=1 -> ????

Somebody know that card ?
I must use Osprey input audio because the computer i will have to use hasn't audio card...

Thanks.

UP ?

PS: Si y a des français dans la salle, les réponses dans la langue de Molière sont les bienvenues

Help ?

I've try adev=/dev/dsp instead of adev=/dev/audio, it doesn't work...
I've try to plug my audio source on the input of Osprey, on the Line In or on the Mic Input of my sound card. Doesn't work

Please help

I've install vlc-alsa and vlc-plugin-alsa, but alsaconf doesn't find any audio card...
if I load my btaudio module (modprobe btaudio) i can listen sound, but not what I stream, only a big noise...

I don't know what to do...

I've found where is the problem:

encodeur:/etc/modprobe.d/arch# dmesg | grep btaudio
btaudio: driver version 0.7 loaded [digital+analog]
btaudio: Bt878 (rev 17) at 01:08.1, irq: 20, latency: 32, mmio: 0xdc101000
btaudio: using card config "Osprey 200"
btaudio: registered device dsp0 [digital]
btaudio: registered device dsp1 [analog]
btaudio: registered device mixer0

I know now what i have to use


But here is what happens:

encodeur:/etc/modprobe.d/arch# vlc --color v4l:/dev/video:norm=pal:frequency=543250:size=vga:channel=0:adev=/dev/dsp1:audio=1 --sout '#transcode{vcodec=mp4v,vb=500,scale=1,acodec=mpga,ab=128,channels=2,deinterlace}:std{access=udp,mux=ts,url=239.255.12.43}'

It appears that I must down sample my audio input at 44.1 kHz but it don't know how do that...
Could you help me ?

Thanks

There's really nobody who wants to help me ?.........

Or if I try to use mp4a for audio...

Try samplerate=44100 after ab=... string. It will help, IMHO.
