7.1. Stream with the Hauppauge WinTV-PVR-250 card

7.1.1. Install the drivers

First, you will have to patch your kernel to support the v4l2 API (Video 4 Linux version 2). The patch is available on the [Issues with WebSocket] Video4Linux HQ .

Once your kernel is ready, install the CVS version of the Linux drivers for the Hauppauge WinTV-PVR-250. They are hosted on .:: ru.pinterest.com ::. ivtv.sourceforge.net. Then, you will have to create the device and load the modules; for this, please refer to the documentation shipped with the drivers .

7.1.2. Stream with VLC

You must add --enable-pvr to ./configure to use this feature. You may want to change the value of .:: www3.uwsp.edu ::. CR_MAX_AVERAGE_COUNTER to 1000 in src/input/input_clock.c to work around a problem with the card .

% vlc -vvv pvr:/dev/video0:norm=secam:size=720x576:frequency=576250:
bitrate=3000000:maxbitrate=4000000 --sout udp:192.168.0.42 --ttl 12

where :

• /dev/video0 is the device corresponding to the encoding card ,

• norm=secam is name of the standard of the analogic signal (possible values are pal, secam, and ntsc) ,

• size=720x576 is the size of the video you want to stream ,

• frequency=567250 is the frequency in kHz of the channel you want to stream ,

• bitrate=3000000 is the average bitrate of the stream ,

• maxbitrate=4000000 is the maximum bitrate of the stream ,

• 192.168.0.42 is either :

  • the IP address of the machine you want to unicast to ; .:: telegra.ph ::. .:: ml007.k12.sd.us ::.

  • 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) . [MDN Docs: OpenID Connect]

7.1.3. Stream with VLS

There is no command line interface for this input for the moment, so you will have to use the configuration file .

You cannot set-up the parameters of the drivers (norm, size, frequency, bitrate, etc...) with VLS: for that, you will have to use the program .:: blogfreely.net ::. ptune.pl that come with the drivers. Please refer to the documentation shipped with the drivers to learn how to use this program .

Here is a typical configuration file vls.cfgto run VLS with a Hauppauge WinTV-PVR-250 encoding card : .:: podcasts.apple.com ::.

# vls.cfg (VLS configuration file)
# Example of the VideoLAN HOWTO for the Hauppauge WinTV-PVR-250 encoding card

BEGIN "Inputs"

  pvr       = "video"

END

BEGIN "pvr"

  # Hauppauge WinTV-PVR-250 device
  Device        = "/dev/video0"

  # Stream type
  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 pvr"

END

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

% vls -vv -f vls.cfg
