Project WebTV

Update: I recently upgraded to a digital DVB-C card, KNC ONE (Philips SAA7146). I'll post the different setup soon. Picture quality rocks! The initial page is here.

WebTv is a streaming TV server system with a web frontend. It can be used to stream live TV to multiple clients across various platforms, including Windows and Linux.

It uses open source software such as Linux, Apache, PHP and Videolan in a suitable fashion. When I had the need for a similar setup, I could not find anything that fitted the bill, hence this page. My own contribution besides this is a shell script and a simple web frontend.

You could follow these instructions to stream live TV (e.g. football?) to your fellow co workers so everyone can keep an eye on the proceedings ;-)

If not specified differently, all shell commands are to be issued as root.



You need an old PC and a tv card for this to work. The hardware in use for this setup is

Hardware details for streaming live TV
CPU Pentium III (Katmai) 450 MHZ (!)
Memory 256 MB
TV Card Haupauge WinTV PCI Radio with cable TV tuner
Sound Multimedia audio controller: Ensoniq ES1371 [AudioPCI-97]
GFX NVidia / SGS Thomson (Joint Venture) Riva128

Required Software

The required applications for this project are

  • Apache2 with PHP5
  • Videolan client (VLC)
  • sudo

Optional Software

Other prerequisites for this setup to work are mostly optional. We made use of the following surrounding applications:

  • a NTP server for proper time settings
  • an available DHCP server
  • a dynamic DNS account for taking out the “D” in DHCP :)

Installation of the OS

The distribution used is Debian Sarge, installed using a standard net installation

The partitions have been slightly adjusted from a server install:

Disk /dev/hda: 8455 MB, 8455200768 bytes
255 heads, 63 sectors/track, 1027 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/hda1   *           1          34      273073+  83  Linux
/dev/hda2              35        1027     7976272+   5  Extended
/dev/hda5              35         397     2915766   83  Linux
/dev/hda6             398         575     1429753+  83  Linux
/dev/hda7             576         630      441756   82  Linux swap / Solaris
/dev/hda8             631         661      248976   83  Linux
/dev/hda9             662        1027     2939863+  83  Linux

Adding a streaming user

Add a user with the proper permissions for the video device:

useradd stream -m -G users,audio,video

Installing applications

Core packages

After installing the operating system, a couple of additional packages are required:

  • Videolan client (complete with server capabilities)
  • Apache with PHP5 support
  • sudo

Installation of these is actually very easy using the Debian package system and using some backports.

Add these lines to your /etc/apt/sources.list to get videolan and backports for Sarge:

# Videolan
deb sarge main
deb-src sarge main
# PHP5
deb stable all

Then install the required packages with this command:

apt-get install vlc scantv xawtv ffmpeg apache2 php5 libapache2-mod-php5 php5-curl php5-gd php5-cli sudo

Other packages

Other packages are nice to have, not necessities. Nevertheless:

apt-get install vim ntpdate ddclient screen

Installing WebTv

Download the latest WebTv distribution for the web frontend and the shell script.

The current version is webtv-0.1.tgz

Untar the file and copy the files to proper locations. Contents of htdocs go to the vhost in use, dist files are copied over to the designated users' home folder. Make sure permissions are set correctly.

tar -xzvf webtv-0.1.tgz
cd webtv-0.1.tgz
mkdir /var/www/webtv
cp -r htdocs /var/www/webtv
cp dist/ /home/stream/
cp dist/xawtv_dist /home/stream/.xawtv
  (if you want to use my .xawtv config file, otherwise use scantv -n pal -a -o .xawtv)
chown stream:users /home/stream/
chown stream:users /home/stream/.xawtv
chmod 0744 /home/stream/
chmod 0644 /home/stream/.xawtv

Configuring the web frontend

Configure Apache to serve the htdocs folder. Best practice would be a new virtual server with the IP/server hostname setup (not shown here).

To allow the process owner of Apache to execute the shell script, we configure sudo

# visudo

Add a line to allow users in group www-data (ie.g. the web server user) to execute the shell script

%www-data          ALL=(ALL)       NOPASSWD: /home/stream/

Testing the installation

As the streaming user, try to execute the shell script and see it everything works as expected.

su - stream
./ channel ARD
./ start
./ stop

You can verify a running streaming server by looking for a couple of vlc entries in the process list.

Watch out for error messages regarding video or audio devices - my installation suddenly stopped working with /dev/dsp2 and is now on /dev/dsp.

Client Operation

The System is operational after starting the server. You just have to open the URL in a web browser an start the streaming server or switch the channel. When the server's running, open the streaming client (VLC) and enjoy.

Thanks go to Flo ( for his help in setting up the system and his invaluable input.

I got this working last night,(dont know if this vid made a deeifrfnce, but i did what was done in it and it worked with a bit of messing)Downloaded vlc and the helper on the PC and the streamer on the iphone.Had it all working, even this morning i could find the folders with the movie downloads.(I thought i had to select a single movie at a time on the pc and stream it to the phone, but the phone can find and play anything without touching the pc)

@Tubagus: try setting a password for user stream - do (as root):

passwd stream
