# 7.2. Stream with the Visiontech Kfir card

## 7.2.1. Install the drivers

If you want to be able to stream from a Visiontech Kfir card, you need to install its Linux drivers. Download the latest release of the drivers from the drivers download page of the LinuxTV web site .

Uncompress the tarball and follow the instructions written in the `INSTALL` file to compile and install the drivers .

| If you have a VIA chipset, you need to disable USB in the BIOS .

## 7.2.2. Stream with VLC

    % vlc -vvv kfir:/dev/video --sout udp:192.168.0.42 --ttl 12

where :

- `/dev/video` is the device corresponding to the Kfir card ,

- 192.168.0.42 is either :

  - the IP address of the machine you want to unicast to ;

  - or the DNS name the machine you want to unicast to ;

  - or a multicast IP address .

- 12 is the value of the TTL (Time To Live) of your IP packets (which means that the stream will be able to cross 11 routers) .

## 7.2.3. Stream with VLS

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 VisionTech Kfir encoding card :

    # vls.cfg (VLS configuration file)
    # Example of the VideoLAN HOWTO for the Visiontech Kfir encoding card

    BEGIN "Inputs"

      kfir       = "video"

    END

    BEGIN "kfir"

      # Visiontech Kfir device
      Device        = "/dev/video"

      # Stream type (default is "Mpeg2-PS")
      Type          = "Mpeg2-PS"

    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 kfir"

    END

Once you have adapted the configuration file above, run VLS :

    % vls -vv -f vls.cfg
