Hi all

I'm testing  a multi-input video capture card on cvs-vls version. I 
tryed to configure it as a v4l input, but following vls message error 
 is shown:

VideoLAN Server v 0.5.5-cvs (May 12 2003) - (c)1999-2002 VideoLAN
2003-05-13 10:26:04 [ERROR/Vls]  Input type "v4l" invalid

Multi-input video capture card is a Spectra8 with a BT878 chipset.

But I'm tested a tuner card (Pinnacle PCTV with BT878 chipset) too and 
it run ok. I've used the composite input of it to capture video in real 
time.

The vls.cfg file is:


# Streams sources declaration
BEGIN "Inputs"
# --- Format:
# InputName     = "Type"
# --- Example:
#  local1       = "local"               # Local input example
#  kfir         = "video"               # Video input example (mpeg encoder)
#  dvb          = "dvb"                 # Video input example (DVB card)
#  webcam       = "v4l"            # Video For Linux example (webcam)
  tuner    = "v4l"            # Video For Linux example (composite)
END

#AudioChannel  = "2"              # 1=mono, 2=stereo
END


Any help any Idea ?

Thanks a lot and regards
