# 8.3. Stream with VLS

| 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.cfg`to 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
