  24       <div class="date"> 8th February 2015</div>
  25       <div class="body"><p>When running a TV station with both broadcast and web stream
  26 distribution, it is useful to know that the stream is working.  As I
  27 am involved in the Norwegian open channel
  28 <a href="http://www.frikanalen.no/">Frikanalen</a> as part of my
  29 activity in the <a href="http://www.nuug.no/">NUUG member
  30 organisation</a>, I wrote a script to use mplayer to connect to a
  31 video stream, pick two images 35 seconds apart and compare them.  If
  32 the images are missing or identical, something is probably wrong with
  33 the stream and an alarm should be triggered.  The script is written as
  34 a Nagios plugin, allowing us to use Nagios to run the check regularly
  35 and sound the alarm when something is wrong.  It is able to detect
  36 both a hanging and a broken video stream.</p>
  37
  38 <p>I just uploaded the code for the script into the
  39 <a href="https://github.com/Frikanalen/frikanalen/blob/master/nagios-plugin/check_video_stream_images">Frikanalen
  40 git repository</a> on github.  If you run a TV station with web
  41 streaming, perhaps you can find it useful too.</p>
  42
  43 <p>Last year, the Frikanalen public TV station transformed into using
  44 only Linux based free software to administrate, schedule and
  45 distribute the TV content.  The
  46 <a href="https://github.com/Frikanalen">source code for the entire TV
  47 station</a> is available from the Github project page.  Everyone can
  48 use it to send their content on national TV, and we provide both a web
  49 GUI and <a href="http://beta.frikanalen.tv/api/">a web API</a> to
  50 <a href="http://beta.frikanalen.tv/login/?next=/members/video/">add</a>
  51 and <a href="http://beta.frikanalen.tv/members/plan/">schedule
  52 content</a>.  And thanks to last weeks developer gathering and
  53 following activity, we now have the schedule
  54 <a href="http://beta.frikanalen.tv/xmltv/2015/01/01">available as
  55 XMLTV</a> too.  Still a lot of work left to do, especially with the
  56 process to add videos and with the scheduling, so your contribution is
  57 most welcome.  Perhaps you want to set up your own TV station?</p>
  58
  59 <p>Update 2015-02-25: Got a tip from Uninett about their
  60 <a href="https://scm.uninett.no/maalepaaler/qstream/">qstream
  61 monitoring system</a>, which gather connection time, jitter, packet
  62 loss and burst bandwidth usage.  It look useful to check if UDP
  63 streams are working as they should.</p>
