                <description>&lt;p&gt;Recently I have spent some time evaluating the multimedia browser
plugins available in Debian Lenny, to see which one we should use by
default in Debian Edu.  We need an embedded video playing plugin with
control buttons to pause or stop the video, and capable of streaming
all the multimedia content available on the web.  The test results and
notes are available on
&lt;a href=&quot;http://wiki.debian.org/DebianEdu/BrowserMultimedia&quot;&gt;the
Debian wiki&lt;/a&gt;.  I was surprised how few of the plugins are able to
fill this need.  My personal video player favorite, VLC, has a really
bad plugin which fail on a lot of the test pages.  A lot of the MIME
types I would expect to work with any free software player (like
video/ogg), just do not work.  And simple formats like the
audio/x-mplegurl format (m3u playlists), just isn&#39;t supported by the
totem and vlc plugins.  I hope the situation will improve soon.  No
wonder sites use the proprietary Adobe flash to play video.&lt;/p&gt;

&lt;p&gt;For Lenny, we seem to end up with the mplayer plugin.  It seem to
be the only one fitting our needs. :/&lt;/p&gt;

                <description>&lt;p&gt;As part of the work we do in &lt;a href=&quot;http://www.nuug.no&quot;&gt;NUUG&lt;/a&gt;
to publish video recordings of our monthly presentations, we provide a
page with embedded video for easy access to the recording.  Putting a
good set of HTML tags together to get working embedded video in all
browsers and across all operating systems is not easy.  I hope this
will become easier when the &amp;lt;video&amp;gt; tag is implemented in all
browsers, but I am not sure.  We provide the recordings in several
formats, MPEG1, Ogg Theora, H.264 and Quicktime, and want the
browser/media plugin to pick one it support and use it to play the
recording, using whatever embed mechanism the browser understand.
There is at least four different tags to use for this, the new HTML5
&amp;lt;video&amp;gt; tag, the &amp;lt;object&amp;gt; tag, the &amp;lt;embed&amp;gt; tag and
the &amp;lt;applet&amp;gt; tag.  All of these take a lot of options, and
finding the best options is a major challenge.&lt;/p&gt;

&lt;p&gt;I just tested the experimental Opera browser available from &lt;a
href=&quot;http://labs.opera.com&quot;&gt;labs.opera.com&lt;/a&gt;, to see how it handled
a &amp;lt;video&amp;gt; tag with a few video sources and no extra attributes.
I was not very impressed.  The browser start by fetching a picture
from the video stream.  Not sure if it is the first frame, but it is
definitely very early in the recording.  So far, so good. Next,
instead of streaming the 76 MiB video file, it start to download all
of it, but do not start to play the video.  This mean I have to wait
for several minutes for the downloading to finish.  When the download
is done, the playing of the video do not start!  Waiting for the
download, but I do not get to see the video?  Some testing later, I
discover that I have to add the controls=&quot;true&quot; attribute to be able
to get a play button to pres to start the video.  Adding
autoplay=&quot;true&quot; did not help.  I sure hope this is a misfeature of the
test version of Opera, and that future implementations of the
&amp;lt;video&amp;gt; tag will stream recordings by default, or at least start
playing when the download is done.&lt;/p&gt;

&lt;p&gt;The test page I used (since changed to add more attributes) is
&lt;a href=&quot;http://www.nuug.no/aktiviteter/20090113-foredrag-om-foredrag/&quot;&gt;available
from the nuug site&lt;/a&gt;.  Will have to test it with the new Firefox
too.&lt;/p&gt;

&lt;p&gt;In the test process, I discovered a missing feature.  I was unable
to find a way to get the URL of the playing video out of Opera, so I
am not quite sure it picked the Ogg Theora version of the video.  I
sure hope it was using the announced Ogg Theora support. :)&lt;/p&gt;

                <description>&lt;p&gt;I
&lt;a href=&quot;http://www.regjeringen.no/upload/FAD/Vedlegg/Hoeringer/Refkat_V2/MicrosoftNorge.pdf&quot;&gt;Microsoft
sin høringsuttalelse&lt;/a&gt; til
&lt;a href=&quot;http://www.regjeringen.no/nb/dep/fad/dok/horinger/horingsdokumenter/2009/horing---referansekatalog-versjon-2.html?id=549422&quot;&gt;forslag
til versjon 2 av statens referansekatalog over standarder&lt;/a&gt;, lirer
de av seg følgende FUD-perle:&lt;/p&gt;

&lt;p&gt;&lt;blockquote&gt;&quot;Vorbis, OGG, Theora og FLAC er alle tekniske
  spesifikasjoner overordnet styrt av xiph.org, som er en
  ikke-kommersiell organisasjon.  Etablerte og anerkjente
  standardiseringsorganisasjoner, som Oasis, W3C og Ecma, har en godt
  innarbeidet vedlikeholds- og forvaltningsprosess av en standard.
  Det er derimot helt opp til hver enkelt organisasjon å bestemme
  hvordan tekniske spesifikasjoner videreutvikles og endres, og disse
  spesifikasjonene bør derfor ikke defineres som åpne
  standarder.&quot;&lt;/blockquote&gt;&lt;/p&gt;

&lt;p&gt;De vokter seg vel for å nevne den anerkjente
standardiseringsorganisasjonen IETF, som er organisasjonen bak HTTP,
IP og det meste av protokoller på Internet, og RFC-standardene som
IETF står bak.  Ogg er spesifisert i
&lt;a href=&quot;http://ietf.org/rfc/rfc3533.txt&quot;&gt;RFC 3533&lt;/a&gt;, og er uten
tvil å anse som en åpen standard.  Vorbis er
&lt;a href=&quot;http://ietf.org/rfc/rfc5215.txt&quot;&gt;RFC 5215&lt;/a&gt;.  Theora er

under standardisering via IETF, med
&lt;a href=&quot;http://svn.xiph.org/trunk/theora/doc/draft-ietf-avt-rtp-theora-00.txt&quot;&gt;siste
utkast publisert 2006-07-21&lt;/a&gt; (riktignok er dermed teksten ikke
skrevet i stein ennå, men det blir neppe endringer som ikke er
bakoverkompatibel).  De kan være inne på noe når det gjelder FLAC da
jeg ikke finner tegn til at &lt;a
href=&quot;http://flac.sourceforge.net/format.html&quot;&gt;spesifikasjonen
tilgjengelig på web&lt;/a&gt; er på tur via noen
standardiseringsorganisasjon, men i og med at folkene bak Ogg, Theora
og Vorbis også har involvert seg i Flac siden 2003, så ser jeg ikke
bort fra at også den organiseres via IETF.  Jeg kjenner personlig lite
til FLAC.&lt;/p&gt;

&lt;p&gt;Uredelig argumentasjon bør en holde seg for god til å komme med,
spesielt når det er så enkelt i dagens Internet-hverdag å gå
misvisende påstander etter i sømmene.&lt;/p&gt;

                <title>Regjerningen forlater prinsippet om ingen royalty-betaling i standardkatalogen versjon 2</title>
                <link>http://people.skolelinux.org/pere/blog/Regjerningen_forlater_prinsippet_om_ingen_royalty_betaling_i_standardkatalogen_versjon_2.html</link>        
                <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Regjerningen_forlater_prinsippet_om_ingen_royalty_betaling_i_standardkatalogen_versjon_2.html</guid>
                <pubDate>Mon, 6 Jul 2009 21:00:00 +0200</pubDate>
                <description>&lt;p&gt;Jeg ble glad da regjeringen
&lt;a href=&quot;http://www.digi.no/817635/her-er-statens-nye-it-standarder&quot;&gt;annonserte&lt;/a&gt;
versjon 2 av
&lt;a href=&quot;http://www.regjeringen.no/upload/FAD/Vedlegg/IKT-politikk/Referansekatalogen_versjon2.pdf&quot;&gt;statens
referansekatalog over standarder&lt;/a&gt;, men trist da jeg leste hva som
faktisk var vedtatt etter
&lt;a href=&quot;http://www.regjeringen.no/nb/dep/fad/dok/horinger/horingsdokumenter/2009/horing---referansekatalog-versjon-2.html&quot;&gt;høringen&lt;/a&gt;.
De fleste av de valgte åpne standardene er gode og vil bidra til at
alle kan delta på like vilkår i å lage løsninger for staten, men
noen av dem blokkerer for de som ikke har anledning til å benytte
spesifikasjoner som krever betaling for bruk (såkalt
royalty-betaling).  Det gjelder spesifikt for H.264 for video og MP3
for lyd.  Så lenge bruk av disse var valgfritt mens Ogg Theora og Ogg
Vorbis var påkrevd, kunne alle som ønsket å spille av video og lyd
fra statens websider gjøre dette uten å måtte bruke programmer der
betaling for bruk var nødvendig.  Når det nå er gjort valgfritt for
de statlige etatene å bruke enten H.264 eller Theora (og MP3 eler
Vorbis), så vil en bli tvunget til å forholde seg til
royalty-belastede standarder for å få tilgang til videoen og
lyden.&lt;/p&gt;

&lt;p&gt;Det gjør meg veldig trist at regjeringen har forlatt prinsippet om
at alle standarder som ble valgt til å være påkrevd i katalogen skulle
være uten royalty-betaling.  Jeg håper det ikke betyr at en har mistet
all forståelse for hvilke prinsipper som må følges for å oppnå
likeverdig konkurranse mellom aktørene i IT-bransjen.  NUUG advarte
mot dette i
&lt;a href=&quot;http://wiki.nuug.no/uttalelser/200901-standardkatalog-v2&quot;&gt;sin
høringsuttalelse&lt;/a&gt;, men ser ut til å ha blitt ignorert.&lt;/p&gt;

                <link>http://people.skolelinux.org/pere/blog/Regjerningens_oppsummering_av_h_ringen_om_standardkatalogen_versjon_2.html</link>        
                <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Regjerningens_oppsummering_av_h_ringen_om_standardkatalogen_versjon_2.html</guid>
                <pubDate>Thu, 9 Jul 2009 14:40:00 +0200</pubDate>
                <description>&lt;p&gt;For å forstå mer om hvorfor standardkatalogens versjon 2 ble som
den ble, har jeg bedt om kopi fra FAD av dokumentene som ble lagt frem
for regjeringen da de tok sin avgjørelse.  De er nå lagt ut på NUUGs
wiki, direkte tilgjengelig via &quot;&lt;a
href=&quot;http://wiki.nuug.no/uttalelser/200901-standardkatalog-v2?action=AttachFile&amp;do=get&amp;target=kongelig-resolusjon.pdf&quot;&gt;Referansekatalogen
v2.0 - Oppsummering av høring&lt;/a&gt;&quot; og &quot;&lt;a
href=&quot;http://wiki.nuug.no/uttalelser/200901-standardkatalog-v2?action=AttachFile&amp;do=get&amp;target=kongelig-resolusjon-katalogutkast.pdf&quot;&gt;Referansekatalog
for IT-standarder i offentlig sektor Versjon 2.0, dd.mm.åååå -
UTKAST&lt;/a&gt;&quot;.&lt;/p&gt;

&lt;p&gt;Det er tre ting jeg merker meg i oppsummeringen fra
høringsuttalelsen da jeg skummet igjennom den.  Det første er at
forståelsen av hvordan programvarepatenter påvirker fri
programvareutvikling også i Norge når en argumenterer med at
royalty-betaling ikke er et relevant problem i Norge.  Det andre er at
FAD ikke har en prinsipiell forståelse av verdien av en enkelt
standard innenfor hvert område.  Det siste er at påstander i
høringsuttalelsene ikke blir etterprøvd (f.eks. påstanden fra
Microsoft om hvordan Ogg blir standardisert og påstanden fra
politidirektoratet om patentproblemer i Theora).&lt;/p&gt;

                <title>Some notes on Flash in Debian and Debian Edu</title>
                <link>http://people.skolelinux.org/pere/blog/Some_notes_on_Flash_in_Debian_and_Debian_Edu.html</link>        
                <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Some_notes_on_Flash_in_Debian_and_Debian_Edu.html</guid>
                <pubDate>Sat, 4 Sep 2010 10:10:00 +0200</pubDate>
                <description>&lt;p&gt;In the &lt;a href=&quot;http://popcon.debian.org/unknown/by_vote&quot;&gt;Debian
popularity-contest numbers&lt;/a&gt;, the adobe-flashplugin package the
second most popular used package that is missing in Debian.  The sixth
most popular is flashplayer-mozilla.  This is a clear indication that
working flash is important for Debian users.  Around 10 percent of the
users submitting data to popcon.debian.org have this package
installed.&lt;/p&gt;

&lt;p&gt;In the report written by Lars Risan in August 2008
(«&lt;a href=&quot;http://wiki.skolelinux.no/Dokumentasjon/Rapporter?action=AttachFile&amp;do=view&amp;target=Skolelinux_i_bruk_rapport_1.0.pdf&quot;&gt;Skolelinux
i bruk – Rapport for Hurum kommune, Universitetet i Agder og
stiftelsen SLX Debian Labs&lt;/a&gt;»), one of the most important problems
schools experienced with &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Debian
Edu/Skolelinux&lt;/a&gt; was the lack of working Flash.  A lot of educational
web sites require Flash to work, and lacking working Flash support in
the web browser and the problems with installing it was perceived as a
good reason to stay with Windows.&lt;/p&gt;

&lt;p&gt;I once saw a funny and sad comment in a web forum, where Linux was
said to be the retarded cousin that did not really understand
everything you told him but could work fairly well.  This was a
comment regarding the problems Linux have with proprietary formats and
non-standard web pages, and is sad because it exposes a fairly common
understanding of whose fault it is if web pages that only work in for
example Internet Explorer 6 fail to work on Firefox, and funny because
it explain very well how annoying it is for users when Linux
distributions do not work with the documents they receive or the web
pages they want to visit.&lt;/p&gt;

&lt;p&gt;This is part of the reason why I believe it is important for Debian
and Debian Edu to have a well working Flash implementation in the
distribution, to get at least popular sites as Youtube and Google
Video to working out of the box.  For Squeeze, Debian have the chance
to include the latest version of Gnash that will make this happen, as
the new release 0.8.8 was published a few weeks ago and is resting in
unstable.  The new version work with more sites that version 0.8.7.
The Gnash maintainers have asked for a freeze exception, but the
release team have not had time to reply to it yet.  I hope they agree
with me that Flash is important for the Debian desktop users, and thus
accept the new package into Squeeze.&lt;/p&gt;

                <title>Terms of use for video produced by a Canon IXUS 130 digital camera</title>
                <link>http://people.skolelinux.org/pere/blog/Terms_of_use_for_video_produced_by_a_Canon_IXUS_130_digital_camera.html</link>

                <pubDate>Thu, 9 Sep 2010 23:55:00 +0200</pubDate>
                <description>&lt;p&gt;A few days ago I had the mixed pleasure of bying a new digital
camera, a Canon IXUS 130.  It was instructive and very disturbing to
be able to verify that also this camera producer have the nerve to
specify how I can or can not use the videos produced with the camera.
Even thought I was aware of the issue, the options with new cameras
are limited and I ended up bying the camera anyway.  What is the
problem, you might ask?  It is software patents, MPEG-4, H.264 and the
MPEG-LA that is the problem, and our right to record our experiences
without asking for permissions that is at risk.

&lt;p&gt;On page 27 of the Danish instruction manual, this section is
written:&lt;/p&gt;

&lt;blockquote&gt;
&lt;p&gt;This product is licensed under AT&amp;T patents for the MPEG-4 standard
and may be used for encoding MPEG-4 compliant video and/or decoding
MPEG-4 compliant video that was encoded only (1) for a personal and
non-commercial purpose or (2) by a video provider licensed under the
AT&amp;T patents to provide MPEG-4 compliant video.&lt;/p&gt;

&lt;p&gt;No license is granted or implied for any other use for MPEG-4
standard.&lt;/p&gt;
&lt;/blockquote&gt;

&lt;p&gt;In short, the camera producer have chosen to use technology
(MPEG-4/H.264) that is only provided if I used it for personal and
non-commercial purposes, or ask for permission from the organisations
holding the knowledge monopoly (patent) for technology used.&lt;/p&gt;

&lt;p&gt;This issue has been brewing for a while, and I recommend you to
read
&quot;&lt;a href=&quot;http://www.osnews.com/story/23236/Why_Our_Civilization_s_Video_Art_and_Culture_is_Threatened_by_the_MPEG-LA&quot;&gt;Why
Our Civilization&#39;s Video Art and Culture is Threatened by the
MPEG-LA&lt;/a&gt;&quot; by Eugenia Loli-Queru and
&quot;&lt;a href=&quot;http://webmink.com/2010/09/03/h-264-and-foss/&quot;&gt;H.264 Is Not
The Sort Of Free That Matters&lt;/a&gt;&quot; by Simon Phipps to learn more about
the issue.  The solution is to support the
&lt;a href=&quot;http://www.digistan.org/open-standard:definition&quot;&gt;free and
open standards&lt;/a&gt; for video, like &lt;a href=&quot;http://www.theora.org/&quot;&gt;Ogg
Theora&lt;/a&gt;, and avoid MPEG-4 and H.264 if you can.&lt;/p&gt;

                <title>Pledge for funding to the Gnash project to get AVM2 support</title>
                <link>http://people.skolelinux.org/pere/blog/Pledge_for_funding_to_the_Gnash_project_to_get_AVM2_support.html</link>        
                <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Pledge_for_funding_to_the_Gnash_project_to_get_AVM2_support.html</guid>
                <pubDate>Tue, 19 Oct 2010 14:45:00 +0200</pubDate>
                <description>&lt;p&gt;&lt;a href=&quot;http://www.getgnash.org/&quot;&gt;The Gnash project&lt;/a&gt; is the
most promising solution for a Free Software Flash implementation. It
has done great so far, but there is still far to go, and recently its
funding has dried up.  I believe AVM2 support in Gnash is vital to the
continued progress of the project, as more and more sites show up with
AVM2 flash files.&lt;/p&gt;

&lt;p&gt;To try to get funding for developing such support, I have started
&lt;a href=&quot;http://www.pledgebank.com/gnash-avm2&quot;&gt;a pledge&lt;/a&gt; with the
following text:&lt;/P&gt;

&lt;p&gt;&lt;blockquote&gt;

  &lt;p&gt;&quot;I will pay 100$ to the Gnash project to develop AVM2 support but
  only if 10 other people will do the same.&quot;&lt;/p&gt;

  &lt;p&gt;- Petter Reinholdtsen, free software developer&lt;/p&gt;

  &lt;p&gt;Deadline to sign up by: 24th December 2010&lt;/p&gt;

  &lt;p&gt;The Gnash project need to get support for the new Flash file
  format AVM2 to work with a lot of sites using Flash on the
  web. Gnash already work with a lot of Flash sites using the old AVM1
  format, but more and more sites are using the AVM2 format these
  days. The project web page is available from
  http://www.getgnash.org/ . Gnash is a free software implementation
  of Adobe Flash, allowing those of us that do not accept the terms of
  the Adobe Flash license to get access to Flash sites.&lt;/p&gt;

  &lt;p&gt;The project need funding to get developers to put aside enough
  time to develop the AVM2 support, and this pledge is my way to try
  to get this to happen.&lt;/p&gt;

  &lt;p&gt;The project accept donations via the OpenMediaNow foundation,
  &lt;a href=&quot;http://www.openmedianow.org/?q=node/32&quot;&gt;http://www.openmedianow.org/?q=node/32&lt;/a&gt; .&lt;/p&gt;

&lt;/blockquote&gt;&lt;/p&gt;

&lt;p&gt;I hope you will support this effort too.  I hope more than 10
people will participate to make this happen.  The more money the
project gets, the more features it can develop using these funds.
:)&lt;/p&gt;

&lt;p&gt;My &lt;a href=&quot;http://pledgebank.com/gnash-avm2&quot;&gt;gnash pledge&lt;/a&gt; to
raise money for the project is going well.  The lower limit of 10
signers was reached in 24 hours, and so far 13 people have signed it.
More signers and more funding is most welcome, and I am really curious
how far we can get before the time limit of December 24 is reached.
:)&lt;/p&gt;

&lt;p&gt;On the #gnash IRC channel on irc.freenode.net, I was just tipped
about what appear to be a great code coverage tool capable of
generating code coverage stats without any changes to the source code.
It is called
&lt;a href=&quot;http://simonkagstrom.github.com/kcov/index.html&quot;&gt;kcov&lt;/a&gt;,
and can be used using &lt;tt&gt;kcov &amp;lt;directory&amp;gt; &amp;lt;binary&amp;gt;&lt;/tt&gt;.
It is missing in Debian, but the git source built just fine in Squeeze
after I installed libelf-dev, libdwarf-dev, pkg-config and
libglib2.0-dev.  Failed to build in Lenny, but suspect that is
solvable.  I hope kcov make it into Debian soon.&lt;/p&gt;

&lt;p&gt;Finally found time to wrap up the release notes for &lt;a
href=&quot;http://lists.debian.org/debian-edu-announce/2010/10/msg00002.html&quot;&gt;a
new alpha release of Debian Edu&lt;/a&gt;, and just published the second
alpha test release of the Squeeze based Debian Edu /
&lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Skolelinux&lt;/a&gt;
release.  Give it a try if you need a complete linux solution for your
school, including central infrastructure server, workstations, thin
client servers and diskless workstations.  A nice touch added
yesterday is RDP support on the thin client servers, for windows
clients to get a Linux desktop on request.&lt;/p&gt;

                <pubDate>Sat, 30 Oct 2010 11:20:00 +0200</pubDate>
                <description>&lt;p&gt;I dag la jeg inn en kommentar på en sak hos NRKBeta
&lt;a href=&quot;http://nrkbeta.no/2010/10/27/bakom-blindpassasjer-del-1/&quot;&gt;om
hvordan TV-serien Blindpassasjer ble laget&lt;/a&gt; i forbindelse med at
filmene NRK la ut ikke var tilgjengelig i et
&lt;a href=&quot;http://www.digistan.org/open-standard:definition&quot;&gt;fritt og
åpent format&lt;/a&gt;.  Dette var det jeg skrev publiserte der 07:39.&lt;/p&gt;

&lt;p&gt;&lt;blockquote&gt;
&lt;p&gt;&quot;Vi fikk en kommentar rundt måten streamet innhold er beskyttet fra
nedlasting.  Mange av oss som kan mer enn gjennomsnittet om systemer
som dette, vet at det stort sett er mulig å lure ut ting med den
nødvendige forkunnskapen.&quot;&lt;/p&gt;

&lt;p&gt;Haha.  Å streame innhold er det samme som å laste ned innhold, så å
beskytte en stream mot nedlasting er ikke mulig.  Å skrive noe slikt
er å forlede leseren.&lt;/p&gt;

&lt;p&gt;Med den bakgrunn blir forklaringen om at noen rettighetshavere kun
vil tillate streaming men ikke nedlasting meningsløs.&lt;/p&gt;

&lt;p&gt;Anbefaler forresten å lese
&lt;a href=&quot;http://blogs.computerworlduk.com/simon-says/2010/10/drm-is-toxic-to-culture/index.htm&quot;&gt;http://blogs.computerworlduk.com/simon-says/2010/10/drm-is-toxic-to-culture/index.htm&lt;/a&gt;
om hva som ville være konsekvensen hvis digitale avspillingssperrer
(DRM) fungerte.  Det gjør de naturligvis ikke teknisk - det er jo
derfor de må ha totalitære juridiske beskyttelsesmekanismer på plass,
men det er skremmende hva samfunnet tillater og NRK er med på å bygge
opp under.&lt;/p&gt;
&lt;/blockquote&gt;&lt;/p&gt;

&lt;p&gt;Ca. 20 minutter senere får jeg følgende epost fra Anders Hofseth i
NRKBeta:&lt;/p&gt;

&lt;p&gt;Hei Petter.
&lt;br&gt;Det du forsøker dra igang er egentlig en interessant diskusjon,
men om vi skal kjøre den i kommentarfeltet her, vil vi kunne bli bedt
om å fjerne blindpassasjer fra nett- tv og det vil heller ikke bli
særlig lett å klarere ut noe annet arkivmateriale på lang tid.&lt;/p&gt;

&lt;p&gt;Dette er en situasjon NRKbeta ikke ønsker, så kommentaren er
fjernet og den delen av diskusjonen er avsluttet på nrkbeta, vi antar
konsekvensene vi beskriver ikke er noe du ønsker heller...&lt;/p&gt;

&lt;p&gt;Med hilsen,
&lt;br&gt;-anders&lt;/p&gt;

&lt;p&gt;Ring meg om noe er uklart: 95XXXXXXX&lt;/p&gt;
&lt;/blockquote&gt;&lt;/p&gt;

&lt;p&gt;Ble så fascinert over denne holdningen, at jeg forfattet og sendte
over følgende svar.  I og med at debatten er fjernet fra NRK Betas
kommentarfelt, så velger jeg å publisere her på bloggen min i stedet.
Har fjernet epostadresser og telefonnummer til de involverte, for å
unngå at de tiltrekker seg uønskede direkte kontaktforsøk.&lt;/p&gt;

&lt;p&gt;[Anders Hofseth]
&lt;br&gt;&gt; Hei Petter.&lt;/p&gt;

&lt;p&gt;Hei.&lt;/p&gt;

&lt;p&gt;&gt; Det du forsøker dra igang er egentlig en interessant diskusjon, men
&lt;br&gt;&gt; om vi skal kjøre den i kommentarfeltet her, vil vi kunne bli bedt om
&lt;br&gt;&gt; å fjerne blindpassasjer fra nett- tv og det vil heller ikke bli
&lt;br&gt;&gt; særlig lett å klarere ut noe annet arkivmateriale på lang tid.&lt;/p&gt;

&lt;p&gt;Godt å se at du er enig i at dette er en interessant diskusjon.  Den
vil nok fortsette en stund til.  :)&lt;/p&gt;

&lt;p&gt;Må innrømme at jeg synes det er merkelig å lese at dere i NRK med
vitende og vilje ønsker å forlede rettighetshaverne for å kunne
fortsette å legge ut arkivmateriale.&lt;/p&gt;

&lt;p&gt;Kommentarer og diskusjoner i bloggene til NRK Beta påvirker jo ikke
faktum, som er at streaming er det samme som nedlasting, og at innhold
som er lagt ut på nett kan lagres lokalt for avspilling når en ønsker
det.&lt;/p&gt;

&lt;p&gt;Det du sier er jo at klarering av arkivmateriale for publisering på
web krever at en holder faktum skjult fra debattfeltet på NRKBeta.
Det er ikke et argument som holder vann. :)&lt;/p&gt;

&lt;p&gt;&gt; Dette er en situasjon NRKbeta ikke ønsker, så kommentaren er fjernet
&lt;br&gt;&gt; og den delen av diskusjonen er avsluttet på nrkbeta, vi antar
&lt;br&gt;&gt; konsekvensene vi beskriver ikke er noe du ønsker heller...&lt;/p&gt;

&lt;p&gt;Personlig ønsker jeg at NRK skal slutte å stikke hodet i sanden og
heller være åpne på hvordan virkeligheten fungerer, samt ta opp kampen
mot de som vil låse kulturen inne.  Jeg synes det er en skam at NRK
godtar å forlede publikum.  Ville heller at NRK krever at innhold som
skal sendes skal være uten bruksbegresninger og kan publiseres i
formater som heller ikke har bruksbegresninger (bruksbegresningene til
H.264 burde få varselbjellene i NRK til å ringe).&lt;/p&gt;

&lt;p&gt;At NRK er med på DRM-tåkeleggingen og at det kommer feilaktive
påstander om at &quot;streaming beskytter mot nedlasting&quot; som bare er egnet
til å bygge opp om en myte som er skadelig for samfunnet som helhet.&lt;/p&gt;

&lt;p&gt;Anbefaler &amp;lt;URL:&lt;a href=&quot;http://webmink.com/2010/09/03/h-264-and-foss/&quot;&gt;http://webmink.com/2010/09/03/h-264-and-foss/&lt;/a&gt;&gt; og en
titt på
&amp;lt;URL: &lt;a href=&quot;http://people.skolelinux.org/pere/blog/Terms_of_use_for_video_produced_by_a_Canon_IXUS_130_digital_camera.html&quot;&gt;http://people.skolelinux.org/pere/blog/Terms_of_use_for_video_produced_by_a_Canon_IXUS_130_digital_camera.html&lt;/a&gt; &gt;.
for å se hva slags bruksbegresninger H.264 innebærer.&lt;/p&gt;

&lt;p&gt;Hvis dette innebærer at NRK må være åpne med at arkivmaterialet ikke
kan brukes før rettighetshaverene også innser at de er med på å skade
samfunnets kultur og kollektive hukommelse, så får en i hvert fall
synliggjort konsekvensene og antagelig mer flammer på en debatt som er
langt på overtid.&lt;/p&gt;

&lt;p&gt;&gt; Ring meg om noe er uklart: XXX&lt;/p&gt;

&lt;p&gt;Intet uklart, men ikke imponert over måten dere håndterer debatten på.
Hadde du i stedet kommet med et tilsvar i kommentarfeltet der en
gjorde det klart at blindpassasjer-blogpostingen ikke var riktig sted
for videre diskusjon hadde dere i mine øyne kommet fra det med
ryggraden på plass.&lt;/p&gt;

&lt;p&gt;PS: Interessant å se at NRK-ansatte ikke bruker NRK-epostadresser.&lt;/p&gt;

&lt;p&gt;Som en liten avslutning, her er noen litt morsomme innslag om temaet.
&amp;lt;URL: &lt;a href=&quot;http://www.archive.org/details/CopyingIsNotTheft&quot;&gt;http://www.archive.org/details/CopyingIsNotTheft&lt;/a&gt; &gt; og
&amp;lt;URL: &lt;a href=&quot;http://patentabsurdity.com/&quot;&gt;http://patentabsurdity.com/&lt;/a&gt; &gt; hadde vært noe å kringkaste på
NRK1. :)&lt;/p&gt;

                <title>Why isn&#39;t Debian Edu using VLC?</title>
                <link>http://people.skolelinux.org/pere/blog/Why_isn_t_Debian_Edu_using_VLC_.html</link>        
                <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Why_isn_t_Debian_Edu_using_VLC_.html</guid>
                <pubDate>Sat, 27 Nov 2010 11:30:00 +0100</pubDate>
                <description>&lt;p&gt;In the latest issue of Linux Journal, the readers choices were
presented, and the winner among the multimedia player were VLC.
Personally, I like VLC, and it is my player of choice when I first try
to play a video file or stream.  Only if VLC fail will I drag out
gmplayer to see if it can do better.  The reason is mostly the failure
model and trust.  When VLC fail, it normally pop up a error message
reporting the problem.  When mplayer fail, it normally segfault or
just hangs.  The latter failure mode drain my trust in the program.&lt;p&gt;

&lt;p&gt;But even if VLC is my player of choice, we have choosen to use
mplayer in &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Debian
Edu/Skolelinux&lt;/a&gt;.  The reason is simple.  We need a good browser
plugin to play web videos seamlessly, and the VLC browser plugin is
not very good.  For example, it lack in-line control buttons, so there
is no way for the user to pause the video.  Also, when I
&lt;a href=&quot;http://wiki.debian.org/DebianEdu/BrowserMultimedia&quot;&gt;last
tested the browser plugins&lt;/a&gt; available in Debian, the VLC plugin
failed on several video pages where mplayer based plugins worked.  If
the browser plugin for VLC was as good as the gecko-mediaplayer
package (which uses mplayer), we would switch.&lt;/P&gt;

&lt;p&gt;While VLC is a good player, its user interface is slightly
annoying.  The most annoying feature is its inconsistent use of
keyboard shortcuts.  When the player is in full screen mode, its
shortcuts are different from when it is playing the video in a window.
For example, space only work as pause when in full screen mode.  I
wish it had consisten shortcuts and that space also would work when in
window mode.  Another nice shortcut in gmplayer is [enter] to restart
the current video.  It is very nice when playing short videos from the
web and want to restart it when new people arrive to have a look at
what is going on.&lt;/p&gt;

                <pubDate>Fri, 29 Jul 2011 08:10:00 +0200</pubDate>
                <description>&lt;p&gt;While at Debconf11, I have several times during discussions
mentioned the issues I believe should be improved in Debian for its
desktop to be useful for more people.  The use case for this is my
parents, which are currently running Kubuntu which solve the
issues.&lt;/p&gt;

&lt;p&gt;I suspect these four missing features are not very hard to
implement.  After all, they are present in Ubuntu, so if we wanted to
do this in Debian we would have a source.&lt;/p&gt;

&lt;ol&gt;

&lt;li&gt;&lt;strong&gt;Simple GUI based upgrade of packages.&lt;/strong&gt; When there
are new packages available for upgrades, a icon in the KDE status bar
indicate this, and clicking on it will activate the simple upgrade
tool to handle it.  I have no problem guiding both of my parents
through the process over the phone.  If a kernel reboot is required,
this too is indicated by the status bars and the upgrade tool.  Last
time I checked, nothing with the same features was working in KDE in
Debian.&lt;/li&gt;

&lt;li&gt;&lt;strong&gt;Simple handling of missing Firefox browser
plugins.&lt;/strong&gt; When the browser encounter a MIME type it do not
currently have a handler for, it will ask the user if the system
should search for a package that would add support for this MIME type,
and if the user say yes, the APT sources will be searched for packages
advertising the MIME type in their control file (visible in the
Packages file in the APT archive).  If one or more packages are found,
it is a simple click of the mouse to add support for the missing mime
type.  If the package require the user to accept some non-free
license, this is explained to the user.  The entire process make it
more clear to the user why something do not work in the browser, and
make the chances higher for the user to blame the web page authors and
not the browser for any missing features.&lt;/li&gt;

&lt;li&gt;&lt;strong&gt;Simple handling of missing multimedia codec/format
handlers.&lt;/strong&gt; When the media players encounter a format or codec
it is not supporting, a dialog pop up asking the user if the system
should search for a package that would add support for it.  This
happen with things like MP3, Windows Media or H.264.  The selection
and installation procedure is very similar to the Firefox browser
plugin handling.  This is as far as I know implemented using a
gstreamer hook.  The end result is that the user easily get access to
the codecs that are present from the APT archives available, while
explaining more on why a given format is unsupported by Ubuntu.&lt;/li&gt;

&lt;li&gt;&lt;strong&gt;Better browser handling of some MIME types.&lt;/strong&gt; When
displaying a text/plain file in my Debian browser, it will propose to
start emacs to show it.  If I remember correctly, when doing the same
in Kunbutu it show the file as a text file in the browser.  At least I
know Opera will show text files within the browser.  I much prefer the
latter behaviour.&lt;/li&gt;

&lt;/ol&gt; 

&lt;p&gt;There are other nice features as well, like the simplified suite
upgrader, but given that I am the one mostly doing the dist-upgrade,
it do not matter much.&lt;/p&gt;

&lt;p&gt;I really hope we could get these features in place for the next
Debian release.  It would require the coordinated effort of several
maintainers, but would make the end user experience a lot better.&lt;/p&gt;

                <title>Hvordan enkelt laste ned filmer fra NRK</title>
                <link>http://people.skolelinux.org/pere/blog/Hvordan_enkelt_laste_ned_filmer_fra_NRK.html</link>

                <pubDate>Sat, 5 Nov 2011 15:20:00 +0100</pubDate>
                <description>&lt;p&gt;Ofte har jeg lyst til å laste ned et innslag fra NRKs nettsted for
å se det senere når jeg ikke er på nett, eller for å ha det
tilgjengelig når jeg en gang i fremtiden ønsker å referere til
innslaget selv om NRK har fjernet det fra sine nettsider.  I dag fant
jeg et lite script som fikser jobben.&lt;/p&gt;

&lt;p&gt;Scriptet er laget av Jan Henning Thorsen og tilgjengelig fra
&lt;a href=&quot;http://jhthorsen.github.com/snippets/nrk-downloader/&quot;&gt;github&lt;/a&gt;,
og gjør det veldig enkelt å laste ned.  Kjør &lt;tt&gt;nrk-downloader.sh
http://www1.nrk.no/nett-tv/klipp/582810&lt;/tt&gt; for å hente ned et enkelt
innslag eller &lt;tt&gt;nrk-downloader.sh
http://www1.nrk.no/nett-tv/kategori/3521&lt;/tt&gt; for å laste ned alle
episodene i en serie.&lt;/p&gt;

&lt;p&gt;Det er ikke rakettforskning å laste ned NRK-&quot;strømmer&quot;, og
tidligere gjorde jeg dette manuelt med mplayer.  Scriptet til
Hr. Thorsen gjør det raskere og enklere for meg, men jeg vil ikke si
at det er en revolusjonerende løsning.  Jeg mener jo fortsatt at
påstanden fra NRKs ansatte om at det er
&lt;a href=&quot;http://people.skolelinux.org/pere/blog/Best___ikke_fortelle_noen_at_streaming_er_nedlasting___.html&quot;&gt;vesensforskjellig
å legge tilgjengelig for nedlasting og for streaming&lt;/a&gt; er
meningsløs.&lt;/p&gt;

                <link>http://people.skolelinux.org/pere/blog/RAND_terms___non_reasonable_and_discriminatory.html</link>        
                <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/RAND_terms___non_reasonable_and_discriminatory.html</guid>
                <pubDate>Thu, 19 Apr 2012 22:20:00 +0200</pubDate>
                <description>&lt;p&gt;Here in Norway, the
&lt;a href=&quot;http://www.regjeringen.no/nb/dep/fad.html?id=339&quot;&gt; Ministry of
Government Administration, Reform and Church Affairs&lt;/a&gt; is behind
a &lt;a href=&quot;http://standard.difi.no/forvaltningsstandarder&quot;&gt;directory of
standards&lt;/a&gt; that are recommended or mandatory for use by the
government.  When the directory was created, the people behind it made
an effort to ensure that everyone would be able to implement the
standards and compete on equal terms to supply software and solutions
to the government.  Free software and non-free software could compete
on the same level.&lt;/p&gt;

&lt;p&gt;But recently, some standards with RAND
(&lt;a href=&quot;http://en.wikipedia.org/wiki/Reasonable_and_non-discriminatory_licensing&quot;&gt;Reasonable
And Non-Discriminatory&lt;/a&gt;) terms have made their way into the
directory.  And while this might not sound too bad, the fact is that
standard specifications with RAND terms often block free software from
implementing them.  The reasonable part of RAND mean that the cost per
user/unit is low,and the non-discriminatory part mean that everyone
willing to pay will get a license.  Both sound great in theory.  In
practice, to get such license one need to be able to count users, and
be able to pay a small amount of money per unit or user.  By
definition, users of free software do not need to register their use.
So counting users or units is not possible for free software projects.
And given that people will use the software without handing any money
to the author, it is not really economically possible for a free
software author to pay a small amount of money to license the rights
to implement a standard when the income available is zero.  The result
in these situations is that free software are locked out from
implementing standards with RAND terms.&lt;/p&gt;

&lt;p&gt;Because of this, when I see someone claiming the terms of a
standard is reasonable and non-discriminatory, all I can think of is
how this really is non-reasonable and discriminatory.  Because free
software developers are working in a global market, it does not really
help to know that software patents are not supposed to be enforceable
in Norway.  The patent regimes in other countries affect us even here.
I really hope the people behind the standard directory will pay more
attention to these issues in the future.&lt;/p&gt;

&lt;p&gt;You can find more on the issues with RAND, FRAND and RAND-Z terms
from Simon Phipps
(&lt;a href=&quot;http://blogs.computerworlduk.com/simon-says/2010/11/rand-not-so-reasonable/&quot;&gt;RAND:
Not So Reasonable?&lt;/a&gt;).&lt;/p&gt;

&lt;p&gt;Update 2012-04-21: Just came across a
&lt;a href=&quot;http://blogs.computerworlduk.com/open-enterprise/2012/04/of-microsoft-netscape-patents-and-open-standards/index.htm&quot;&gt;blog
post from Glyn Moody&lt;/a&gt; over at Computer World UK warning about the
same issue, and urging people to speak out to the UK government.  I
can only urge Norwegian users to do the same for
&lt;a href=&quot;http://www.standard.difi.no/hoyring/hoyring-om-nye-anbefalte-it-standarder&quot;&gt;the
hearing taking place at the moment&lt;/a&gt; (respond before 2012-04-27).
It proposes to require video conferencing standards including
specifications with RAND terms.&lt;/p&gt;

                <description>&lt;p&gt;In &lt;a href=&quot;http://www.idg.no/computerworld/article243690.ece&quot;&gt;an
article today&lt;/a&gt; published by Computerworld Norway, the photographer
&lt;a href=&quot;http://www.urke.com/eirik/&quot;&gt;Eirik Helland Urke&lt;/a&gt; reports
that the video editor application included with
&lt;a href=&quot;http://www.htc.com/www/smartphones/htc-one-x/#specs&quot;&gt;HTC One
X&lt;/a&gt; have some quite surprising terms of use.  The article is mostly
based on the twitter message from mister Urke, stating:

&lt;p&gt;&lt;blockquote&gt;
&quot;&lt;a href=&quot;http://twitter.com/urke/status/194062269724897280&quot;&gt;Drøy
brukeravtale: HTC kan bruke MINE redigerte videoer kommersielt. Selv
kan jeg KUN bruke dem privat.&lt;/a&gt;&quot;
&lt;/blockquote&gt;&lt;/p&gt;

&lt;p&gt;I quickly translated it to this English message:&lt;/p&gt;

&lt;p&gt;&lt;blockquote&gt;
&quot;Arrogant user agreement: HTC can use MY edited videos
commercially.  Although I can ONLY use them privately.&quot;
&lt;/blockquote&gt;&lt;/p&gt;

&lt;p&gt;I&#39;ve been unable to find the text of the license term myself, but
suspect it is a variation of the MPEG-LA terms I
&lt;a href=&quot;http://people.skolelinux.org/pere/blog/Terms_of_use_for_video_produced_by_a_Canon_IXUS_130_digital_camera.html&quot;&gt;discovered
with my Canon IXUS 130&lt;/a&gt;.  The HTC One X specification specifies that
the recording format of the phone is .amr for audio and .mp3 for
video.  AMR is
&lt;a href=&quot;http://en.wikipedia.org/wiki/Adaptive_Multi-Rate_audio_codec#Licensing_and_patent_issues&quot;&gt;Adaptive
Multi-Rate audio codec&lt;/a&gt; with patents which according to the
Wikipedia article require an license agreement with
&lt;a href=&quot;http://www.voiceage.com/&quot;&gt;VoiceAge&lt;/a&gt;.  MP4 is
&lt;a href=&quot;http://en.wikipedia.org/wiki/H.264/MPEG-4_AVC#Patent_licensing&quot;&gt;MPEG4 with
H.264&lt;/a&gt;, which according to Wikipedia require a licence agreement
with &lt;a href=&quot;http://www.mpegla.com/&quot;&gt;MPEG-LA&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;I know why I prefer
&lt;a href=&quot;http://www.digistan.org/open-standard:definition&quot;&gt;free and open
standards&lt;/a&gt; also for video.&lt;/p&gt;

                <description>&lt;p&gt;Trengs det avtale med MPEG-LA for å ha lovlig rett til å
distribuere og kringkaste video i MPEG4 eller med videokodingen H.264?
&lt;a href=&quot;http://webmink.com/essays/h-264/&quot;&gt;H.264 og MPEG4 er jo ikke en
fri og åpen standard&lt;/a&gt; i henhold til
&lt;a href=&quot;http://people.skolelinux.org/pere/blog/Fri_og__pen_standard__slik_Digistan_ser_det.html&quot;&gt;definisjonen
til Digistan&lt;/a&gt;, så i enkelte land er det ingen tvil om at du må ha
en slik avtale, men jeg må innrømme at jeg ikke vet om det også
gjelder Norge.  Det ser uansett ut til å være en juridisk interessant
problemstilling.  Men jeg tenkte her om dagen som så, at hvis det er
nødvendig, så har store aktører som
&lt;a href=&quot;http://www.nrk.no/&quot;&gt;NRK&lt;/a&gt; og
&lt;a href=&quot;http://www.regjeringen.no/&quot;&gt;regjeringen&lt;/a&gt; skaffet seg en
slik avtale.  Jeg har derfor sendt forespørsel til begge (for
regjeringen sin del er det Departementenes Servicesenter som gjør
jobben), og bedt om kopi av eventuelle avtaler de har om bruk av MPEG
og/eller H.264 med MPEG-LA eller andre aktører som opererer på vegne
av MPEG-LA.  Her er kopi av eposten jeg har sendt til
&lt;a href=&quot;http://www.dss.dep.no/&quot;&gt;Departementenes Servicesenter&lt;/a&gt;.
Forespørselen til NRK er veldig lik.&lt;/p&gt;

&lt;br&gt;To: postmottak@dss.dep.no
&lt;br&gt;Subject: Innsynsbegjæring om MPEG/H.264-relaterte avtaler
 
&lt;p&gt;Hei.  Jeg ber herved om innsyn og kopi av dokumenter i DSS relatert
til avtaler rundt bruk av videoformatene MPEG og H.264.  Jeg er
spesielt interessert i å vite om DSS har lisensavtale med MPEG-LA
eller noen som representerer MPEG-LA i Norge.&lt;/p&gt;

&lt;p&gt;MPEG og H.264 er videoformater som brukes både til kringkasting
(f.eks. i bakkenett og kabel-TV) og videopublisering på web, deriblant
via Adobe Flash.  MPEG-LA, &amp;lt;URL:
&lt;a href=&quot;http://www.mpeg-la.com/&quot;&gt;http://www.mpeg-la.com/&lt;/a&gt; &amp;gt;, er
en organisasjon som har fått oppgaven, av de kjente rettighetshavere
av immaterielle rettigheter knyttet til MPEG og H.264, å selge
bruksrett for MPEG og H.264.&lt;/p&gt;

&lt;p&gt;Via regjeringen.no kringkastes med MPEG og H.264-baserte
videoformater, og dette ser ut til å være organisert av DSS.  Jeg
antar dermed at DSS har avtale med en eller annen aktør om dette.&lt;/p&gt;

&lt;p&gt;F.eks. har Adobe Premiere Pro har følgende klausul i følge &amp;lt;URL:
&lt;a href=&quot;http://news.cnet.com/8301-30685_3-20000101-264.html&quot;&gt;http://news.cnet.com/8301-30685_3-20000101-264.html&lt;/a&gt;
&amp;gt;:&lt;/p&gt;

&lt;p&gt;&lt;blockquote&gt;

  &lt;p&gt;6.17. AVC DISTRIBUTION. The following notice applies to software
  containing AVC import and export functionality: THIS PRODUCT IS
  LICENSED UNDER THE AVC PATENT PORTFOLIO LICENSE FOR THE PERSONAL AND
  NON-COMMERCIAL USE OF A CONSUMER TO (a) ENCODE VIDEO IN COMPLIANCE
  WITH THE AVC STANDARD (&quot;AVC VIDEO&quot;) AND/OR (b) DECODE AVC VIDEO THAT
  WAS ENCODED BY A CONSUMER ENGAGED IN A PERSONAL AND NON-COMMERCIAL
  ACTIVITY AND/OR AVC VIDEO THAT WAS OBTAINED FROM A VIDEO PROVIDER
  LICENSED TO PROVIDE AVC VIDEO. NO LICENSE IS GRANTED OR SHALL BE
  IMPLIED FOR ANY OTHER USE. ADDITIONAL INFORMATION MAY BE OBTAINED
  FROM MPEG LA L.L.C. SEE
  &lt;a href=&quot;http://www.mpegla.com&quot;&gt;http://www.mpegla.com&lt;/a&gt;.&lt;/p&gt;

&lt;/blockquote&gt;&lt;/p&gt;

&lt;p&gt;Her er det kun &quot;non-commercial&quot; og &quot;personal and non-commercial&quot;
aktivitet som er tillatt uten ekstra avtale med MPEG-LA.&lt;/p&gt;

&lt;p&gt;Et annet tilsvarende eksempel er Apple Final Cut Pro, som har
følgende klausul i følge &amp;lt;URL:
&lt;a href=&quot;http://images.apple.com/legal/sla/docs/finalcutstudio2.pdf&quot;&gt;http://images.apple.com/legal/sla/docs/finalcutstudio2.pdf&lt;/a&gt;
&amp;gt;:&lt;/p&gt;

&lt;p&gt;&lt;blockquote&gt;

  &lt;p&gt;15. Merknad om H.264/AVC. Hvis Apple-programvaren inneholder
  funksjonalitet for AVC-koding og/eller AVC-dekoding, krever
  kommersiell bruk ekstra lisensiering og følgende gjelder:
  AVC-FUNKSJONALITETEN I DETTE PRODUKTET KAN KUN ANVENDES AV
  FORBRUKERE OG KUN FOR PERSONLIG OG IKKE- KOMMERSIELL BRUK TIL (i)
  KODING AV VIDEO I OVERENSSTEMMELSE MED AVC-STANDARDEN (&quot;AVC-VIDEO&quot;)
  OG/ELLER (ii) DEKODING AV AVC-VIDEO SOM ER KODET AV EN FORBRUKER TIL
  PERSONLIG OG IKKE-KOMMERSIELL BRUK OG/ELLER DEKODING AV AVC-VIDEO
  FRA EN VIDEOLEVERANDØR SOM HAR LISENS TIL Å TILBY
  AVC-VIDEO. INFORMASJON OM ANNEN BRUK OG LISENSIERING KAN INNHENTES
  FRA MPEG LA L.L.C. SE HTTP://WWW.MPEGLA.COM.&lt;/p&gt;
&lt;/blockquote&gt;&lt;/p&gt;
  
&lt;p&gt;Tilsvarende gjelder for andre programvarepakker, kamera, etc som
bruker MPEG og H.264, at en må ha en avtale med MPEG-LA for å ha lov
til å bruke programmet/utstyret hvis en skal lage noe annet enn
private filmer og i ikke-kommersiell virksomhet.&lt;/p&gt;

&lt;p&gt;Jeg er altså interessert i kopi av avtaler DSS har som gjør at en
ikke er begrenset av de generelle bruksvilkårene som gjelder for
utstyr som bruker MPEG og/eller H.264.&lt;/p&gt;
&lt;/blockquote&gt;&lt;/p&gt;

&lt;p&gt;Nå venter jeg spent på svaret.  Jeg planlegger å blogge om svaret
her.&lt;/p&gt;

                <pubDate>Sun, 24 Jun 2012 13:30:00 +0200</pubDate>
                <description>&lt;p&gt;Many years ago, while studying Computer Science at the
&lt;a href=&quot;http://www.uit.no/&quot;&gt;University of Tromsø&lt;/a&gt;, I started
collecting computer related songs for use at parties.  The original
version was written in LaTeX, but a few years ago I got help from
Håkon W. Lie, one of the inventors of W3C CSS, to convert it to HTML
while keeping the ability to create a nice book in PDF format.  I have
not had time to maintain the book for a while now, and guess I should
put it up on some public version control repository where others can
help me extend and update the book.  If anyone is volunteering to help
me with this, send me an email.  Also let me know if there are songs
missing in my book.&lt;/p&gt;

&lt;p&gt;I have not mentioned the book on my blog so far, and it occured to
me today that I really should let all my readers share the joys of
singing out load about programming, computers and computer networks.
Especially now that &lt;a href=&quot;http://debconf12.debconf.org/&quot;&gt;Debconf
12&lt;/a&gt; is about to start (and I am not going).  Want to sing?  Check
out &lt;a href=&quot;http://www.hungry.com/~pere/cs-songbook/&quot;&gt;Petter&#39;s
Computer Science Songbook&lt;/a&gt;.
