+Title: Nagios module to check if the Frikanalen video stream is working
+Tags: english, video, nuug, frikanalen
+Date: 2015-02-08 13:00
+
+<p>When running a TV station with both broadcast and web stream
+distribution, it is useful to know that the stream is working.  As I
+am involved in the Norwegian open channel
+<ahref="http://www.frikanalen.no/">Frikanalen</a> as part of my
+activity in the <ahref="http://www.nuug.no/">NUUG member
+organisation</a>, I wrote a script to use mplayer to connect to a
+video stream, pick two images 35 seconds apart and compare them.  If
+the images are missing or identical, something is probably wrong with
+the stream and an alarm should be triggered.  The script is written as
+a Nagios plugin, allowing us to use Nagios to run the check regularly
+and sound the alarm when something is wrong.  It is able to detect
+both a hanging and a broken video stream.</p>
+
+<p>I just uploaded the code for the script into the
+<a href="https://github.com/Frikanalen/frikanalen/blob/master/nagios-plugin/check_video_stream_images">Frikanalen
+git repository</a> on github.  If you run a TV station with web
+streaming, perhaps you can find it useful too.</p>
+
+<p>Last year, the Frikanalen public TV station transformed into using
+only Linux based free software to administrate, schedule and
+distribute the TV content.  The
+<a href="https://github.com/Frikanalen">source code for the entire TV
+station</a> is available from the Github project page.  Everyone can
+use it to send their content on national TV, and we provide both a web
+GUI and <a href="http://beta.frikanalen.tv/api/">a web API</a> to
+<a href="http://beta.frikanalen.tv/login/?next=/members/video/">add</a>
+and <a href="http://beta.frikanalen.tv/members/plan/">schedule
+content</a>.  And thanks to last weeks developer gathering and
+following activity, we now have the schedule
+<a href="http://beta.frikanalen.tv/xmltv/2015/01/01">available as
+XMLTV</a> too.  Still a lot of work left to do, especially with the
+process to add videos and with the scheduling, so your contribution is
+most welcome.  Perhaps you want to set up your own TV station?</p>
