+ <p>Did you know there is a TV channel broadcasting talks from DebConf
+16 across an entire country? Or that there is a TV channel
+broadcasting talks by or about
+<a href="http://beta.frikanalen.no/video/625529/">Linus Torvalds</a>,
+<a href="http://beta.frikanalen.no/video/625599/">Tor</a>,
+<a href="http://beta.frikanalen.no/video/624019/">OpenID</A>,
+<a href="http://beta.frikanalen.no/video/625624/">Common Lisp</a>,
+<a href="http://beta.frikanalen.no/video/625446/">Civic Tech</a>,
+<a href="http://beta.frikanalen.no/video/625090/">EFF founder John Barlow</a>,
+<a href="http://beta.frikanalen.no/video/625432/">how to make 3D
+printer electronics</a> and many more fascinating topics? It works
+using only free software (all of it
+<a href="http://github.com/Frikanalen">available from Github</a>), and
+is administrated using a web browser and a web API.</p>
+
+<p>The TV channel is the Norwegian open channel
+<a href="http://www.frikanalen.no/">Frikanalen</a>, and I am involved
+via <a href="https://www.nuug.no/">the NUUG member association</a> in
+running and developing the software for the channel. The channel is
+organised as a member organisation where its members can upload and
+broadcast what they want (think of it as Youtube for national
+broadcasting television). Individuals can broadcast too. The time
+slots are handled on a first come, first serve basis. Because the
+channel have almost no viewers and very few active members, we can
+experiment with TV technology without too much flack when we make
+mistakes. And thanks to the few active members, most of the slots on
+the schedule are free. I see this as an opportunity to spread
+knowledge about technology and free software, and have a script I run
+regularly to fill up all the open slots the next few days with
+technology related video. The end result is a channel I like to
+describe as Techno TV - filled with interesting talks and
+presentations.</p>
+
+<p>It is available on channel 50 on the Norwegian national digital TV
+network (RiksTV). It is also available as a multicast stream on
+Uninett. And finally, it is available as
+<a href="http://beta.frikanalen.no/">a WebM unicast stream</a> from
+Frikanalen and NUUG. Check it out. :)</p>

+ </div>
+ <div class="date">
+ 6th June 2016
+ </div>
+ <div class="body">
+ <p>When I set out a few weeks ago to figure out
+<a href="http://people.skolelinux.org/pere/blog/What_is_the_best_multimedia_player_in_Debian_.html">which
+multimedia player in Debian claimed to support most file formats /
+MIME types</a>, I was a bit surprised how varied the sets of MIME types
+the various players claimed support for. The range was from 55 to 130
+MIME types. I suspect most media formats are supported by all
+players, but this is not really reflected in the MimeTypes values in
+their desktop files. There are probably also some bogus MIME types
+listed, but it is hard to identify which one this is.</p>
+
+<p>Anyway, in the mean time I got in touch with upstream for some of
+the players suggesting to add more MIME types to their desktop files,
+and decided to spend some time myself improving the situation for my
+favorite media player VLC. The fixes for VLC entered Debian unstable
+yesterday. The complete list of MIME types can be seen on the
+<a href="https://wiki.debian.org/DebianMultimedia/PlayerSupport">Multimedia
+player MIME type support status</a> Debian wiki page.</p>
+
+<p>The new "best" multimedia player in Debian? It is VLC, followed by
+totem, parole, kplayer, gnome-mpv, mpv, smplayer, mplayer-gui and
+kmplayer. I am sure some of the other players desktop files support
+several of the formats currently listed as working only with vlc,
+toten and parole.</p>
+
+<p>A sad observation is that only 14 MIME types are listed as
+supported by all the tested multimedia players in Debian in their
+desktop files: audio/mpeg, audio/vnd.rn-realaudio, audio/x-mpegurl,
+audio/x-ms-wma, audio/x-scpls, audio/x-wav, video/mp4, video/mpeg,
+video/quicktime, video/vnd.rn-realvideo, video/x-matroska,
+video/x-ms-asf, video/x-ms-wmv and video/x-msvideo. Personally I find
+it sad that video/ogg and video/webm is not supported by all the media
+players in Debian. As far as I can tell, all of them can handle both
+formats.</p>

+ <div class="body">
+ <p>A little more than 11 years ago, one of the creators of Tor, and
+the current President of <a href="https://www.torproject.org/">the Tor
+project</a>, Roger Dingledine, gave a talk for the members of the
+<a href="http://www.nuug.no/">Norwegian Unix User group</a> (NUUG). A
+video of the talk was recorded, and today, thanks to the great help
+from David Noble, I finally was able to publish the video of the talk
+on Frikanalen, the Norwegian open channel TV station where NUUG
+currently publishes its talks. You can
+<a href="http://frikanalen.no/se">watch the live stream using a web
+browser</a> with WebM support, or check out the recording on the video
+on demand page for the talk
+"<a href="http://beta.frikanalen.no/video/625599">Tor: Anonymous
+communication for the US Department of Defence...and you.</a>".</p>
+
+<p>Here is the video included for those of you using browsers with
+HTML video and Ogg Theora support:</p>

+</video></p>
+
+<p>I guess the gist of the talk can be summarised quite simply: If you
+want to help the military in USA (and everyone else), use Tor. :)</p>

+ <p><strong>Where I set out to figure out which multimedia player in
+Debian claim support for most file formats.</strong></p>
+
+<p>A few years ago, I had a look at the media support for Browser
+plugins in Debian, to get an idea which plugins to include in Debian
+Edu. I created a script to extract the set of supported MIME types
+for each plugin, and used this to find out which multimedia browser
+plugin supported most file formats / media types.
+<a href="https://wiki.debian.org/DebianEdu/BrowserMultimedia">The
+result</a> can still be seen on the Debian wiki, even though it have
+not been updated for a while. But browser plugins are less relevant
+these days, so I thought it was time to look at standalone
+players.</p>
+
+<p>A few days ago I was tired of VLC not being listed as a viable
+player when I wanted to play videos from the Norwegian National
+Broadcasting Company, and decided to investigate why. The cause is a
+<a href="https://bugs.debian.org/822245">missing MIME type in the VLC
+desktop file</a>. In the process I wrote a script to compare the set
+of MIME types announced in the desktop file and the browser plugin,
+only to discover that there is quite a large difference between the
+two for VLC. This discovery made me dig up the script I used to
+compare browser plugins, and adjust it to compare desktop files
+instead, to try to figure out which multimedia player in Debian
+support most file formats.</p>
+
+<p>The result can be seen on the Debian Wiki, as
+<a href="https://wiki.debian.org/DebianMultimedia/PlayerSupport">a
+table listing all MIME types supported by one of the packages included
+in the table</a>, with the package supporting most MIME types being
+listed first in the table.</p>
+
+</p>The best multimedia player in Debian? It is totem, followed by
+parole, kplayer, mpv, vlc, smplayer mplayer-gui gnome-mpv and
+kmplayer. Time for the other players to update their announced MIME
+support?</p>

+ <p>Det kommer stadig nye løsninger for å ta lagre unna innslag fra NRK
+for å se på det senere. For en stund tilbake kom jeg over et script
+nrkopptak laget av Ingvar Hagelund. Han fjernet riktignok sitt script
+etter forespørsel fra Erik Bolstad i NRK, men noen tok heldigvis og
+gjorde det <a href="https://github.com/liangqi/nrkopptak">tilgjengelig
+via github</a>.</p>
+
+<p>Scriptet kan lagre som MPEG4 eller Matroska, og bake inn
+undertekster i fila på et vis som blant annet VLC forstår. For å
+bruke scriptet, kopier ned git-arkivet og kjør</p>
+
+<p><pre>
+nrkopptak/bin/nrk-opptak k <ahref="https://tv.nrk.no/serie/bmi-turne/MUHH45000115/sesong-1/episode-1">https://tv.nrk.no/serie/bmi-turne/MUHH45000115/sesong-1/episode-1</a>
+</pre></p>
+
+<p>URL-eksemplet er dagens toppsak på tv.nrk.no. Argument 'k' ber
+scriptet laste ned og lagre som Matroska. Det finnes en rekke andre
+muligheter for valg av kvalitet og format.</p>
+
+<p>Jeg foretrekker dette scriptet fremfor youtube-dl, som
+<a href="http://people.skolelinux.org/pere/blog/Hvordan_enkelt_laste_ned_filmer_fra_NRK_med_den__nye__l_sningen.html">
+nevnt i 2014 støtter NRK</a> og en rekke andre videokilder, på grunn
+av at nrkopptak samler undertekster og video i en enkelt fil, hvilket
+gjør håndtering enklere på disk.</p>
