no sound from capture card stream

Postby raden » 13 Jul 2006 10:50

hello

I have a problem since use vlc on debian sarge, this is command that i ran from console

vlc v4l:/dev/video:adev=/dev/dsp:norm=0:frequency=567250
:sout="#transcode{vcodec=mp4v,vb=1024,scale=1,acodec=mpga,ab=192,channels=2}
:standard{access=udp,mux=ts,url=239.255.255.255:1234}"

and the client side no sound can hear only the video

please help me to solve this problem

Obvious questions:
does it work localy ? (without streaming)
could you paste debug output from VLC on both the server and the client? (add -vvv --color to the command line)

This is the the debug output when am playing locally, but if I play movie file the sound and video can out properly

vlc -vvv --color v4l:/dev/video:adev=/dev/dsp:norm=0:frequency=583250 :sout-all

Thanks to Video LAN forums

Fnally I get a solution, at first this is my wrong when stream from capture card, vlc default is automatically set audio device with /dev/dsp but this is doesn't work on my machine, so I change audio device to /dsp/dsp2 and the sound is out, thats all

This is command line that I use :
vlc --color v4l:/dev/video:adev=/dev/dsp2:norm=0:frequency=567250:size=320x240 :sout="#transcode{vcodec=DIV3,vb=800,scale=1,acodec=vorb,ab=128,channels=2}:standard{access=http,mux=ogg,url=10.31.12.156:1234}"

This command stream capture card to http and the client side I use firefox with mozilla-plugin and this is work verry well.

What distribution are you using ? (you're just missing the mpga audio encoder)

I use Linux with Debian Sarge3.1r0 distribution, vlc is included on cd installer so i just install it and I am use Esound not ALSA and I have install vlc-plugin-esd too. From command line i just type command to use vlc, there is:

# vlc
VLC media player 0.8.2-svn Janus
libhal.c 767 : org.freedesktop.DBus.Error.ServiceDoesNotExist raised
"Service "org.freedesktop.Hal" does not exist"

If I am missing the mpga audio encoder, how to get that encoder?

VLC in debian doesn't ship with the mpga encoder for legal reasons. If you use debian sid, you can install a nightly build from http://nightlies.videolan.org . Those have the encoder. I'm afraid that on sarge you're pretty much on your own.

Oh no.. but when I stream from a file it's work for udp transport with mpga/mp3, why?
I have another question, I already set up vlc vcodec=DIV3 with vb=800 and acodec=Vorb with ab=128, is that mean vlc stream 928bps (800 + 128) to one client if use http protocols, is that true?
