|  | You need the CVS version of VLS. When you compile it, you must do a ./bootstrap and ./configure --enable-v4l --with-ffmpeg=PATH (where PATH is the absolute path to the directory where you compiled ffmpeg, and not the relative path !) . | 
There is no command line interface for this input for the moment, so you will have to use the configuration file .
Here is a typical configuration file vls.cfgto run VLS with a v4l device :
| 
# vls.cfg (VLS configuration file)
# Example of the VideoLAN HOWTO for the Video for Linux input
BEGIN "Inputs"
  webcam       = "v4l"
END
BEGIN "webcam"
  # V4L device
  Device        = "/dev/video"
  # Channel Source : Webcam is often "0"
  #                  TV Card, may be Tuner(0), Composite(1), Svideo(2)
  Channel       = "0"
  # Norm: PAL=0, NTSC=1, SECAM=2
  Norm          = "0"
  # Frequency of the channel in Mhz, multiplied by 16 (tuner cards only)
  Frequency     = "7668"
  # Size possibilities: can be either:
  # - empty string : default size
  # - width x height
  # - subQCIF(128x96), QSIF(160x120), QCIF(176x144), SIF(320x240),
  #   CIF(352x288), VGA (640x480)
  Size          = ""
  # DeInterlace: "0" = no ; "1" = yes
  DeInterlace   = "0"
  # Video compression format: "mpeg1" or "mpeg4"
  Compression   = "mpeg4"
  # Video bitrate (approx.) in kbps
  Bitrate       = "500"
  # Quality: "1.0" (good) to "31.0" (bad)
  Quality       = "1.0"
  # Sound device
  AudioDevice   = "/dev/dsp"
  # Audio compression format: "mp2", "mp3" or "ogg"
  AudioCompression = "mp2"
  # Audio bitrate in kpbs
  AudioBitrate  = "64"
  # Audio frequency ("16000", "22050", "24000", "32000", "44100" or "48000")
  AudioFreq     = "16000"
  # Audio channel: "1" = mono ; "2" = stereo
  AudioChannel  = "2"
END
BEGIN "Channels"
  channel1       = "network"
END
BEGIN "channel1"
  # Unicast or multicast IP address
  DstHost = "192.168.0.42"
  # Destination port
  DstPort = "1234"
  # If it's a multicast IP address, uncomment the line below
  #Type    = "multicast"
  # If it's a multicast IP address, set the "Time To Live" below
  #TTL     = "12"
END
BEGIN "LaunchOnStartUp"
  command1 = "start video channel1 webcam"
END

Once you have adapted the configuration file above, run VLS :
| % vls -vv -f vls.cfg |
