[vlc] Sound problem when trying to read DV from input

[Sébastien Aperghis-Tramoni]

Hello,

First, thanks for all the people who made VideoLAN possible, it's a 
great product, which makes streaming video look like a easy task.

Now, I have a problem with (as said in the subject) the sound when I 
try to read a DV stream from standard input. I searched on VideoLAN web 
site and forums, and first made sure that the IEEE1394 subsystem worked 
properly with

     dvgrab - | mplayer -

and it works perfectly: the image and the sound are very good, with 
only a half-second delay due to the processing.

Next when I try

     dvgrab - | vlc -

it doesn't work. After searching even more on the forums, I found a 
post that advised to add :demux=rawdv

     dvgrab - | vlc - :demux=rawdv

Now I have the image and the sound, but the sound is extremely awful: 
there's a very loud noise which cover most of the normal sound. Trying 
with a headset to avoid a potential audio loop, I hear that it's the 
right channel which has this noise.

I was unable to fond documentation on this :demux option, or on this 
rawdv demuxer.


Does someone have an idea or know where I could find more documentation?

Thanks in advance
