</a>
31 <p>Recently I have spent some time evaluating the multimedia browser
32 plugins available in Debian Lenny, to see which one we should use by
33 default in Debian Edu. We need an embedded video playing plugin with
34 control buttons to pause or stop the video, and capable of streaming
35 all the multimedia content available on the web. The test results and
36 notes are available on
37 <a href=
"http://wiki.debian.org/DebianEdu/BrowserMultimedia">the
38 Debian wiki
</a>. I was surprised how few of the plugins are able to
39 fill this need. My personal video player favorite, VLC, has a really
40 bad plugin which fail on a lot of the test pages. A lot of the MIME
41 types I would expect to work with any free software player (like
42 video/ogg), just do not work. And simple formats like the
43 audio/x-mplegurl format (m3u playlists), just isn't supported by the
44 totem and vlc plugins. I hope the situation will improve soon. No
45 wonder sites use the proprietary Adobe flash to play video.
</p>
47 <p>For Lenny, we seem to end up with the mplayer plugin. It seem to
48 be the only one fitting our needs. :/

69 <p>As part of the work we do in
<a href=
"http://www.nuug.no">NUUG
</a>
70 to publish video recordings of our monthly presentations, we provide a
71 page with embedded video for easy access to the recording. Putting a
72 good set of HTML tags together to get working embedded video in all
73 browsers and across all operating systems is not easy. I hope this
74 will become easier when the
<video
> tag is implemented in all
75 browsers, but I am not sure. We provide the recordings in several
76 formats, MPEG1, Ogg Theora, H
.264 and Quicktime, and want the
77 browser/media plugin to pick one it support and use it to play the
78 recording, using whatever embed mechanism the browser understand.
79 There is at least four different tags to use for this, the new HTML5
80 <video
> tag, the
<object
> tag, the
<embed
> tag and
81 the
<applet
> tag. All of these take a lot of options, and
82 finding the best options is a major challenge.
</p>
84 <p>I just tested the experimental Opera browser available from
<a
85 href=
"http://labs.opera.com">labs.opera.com
</a>, to see how it handled
86 a
<video
> tag with a few video sources and no extra attributes.
87 I was not very impressed. The browser start by fetching a picture
88 from the video stream. Not sure if it is the first frame, but it is
89 definitely very early in the recording. So far, so good. Next,
90 instead of streaming the
76 MiB video file, it start to download all
91 of it, but do not start to play the video. This mean I have to wait
92 for several minutes for the downloading to finish. When the download
93 is done, the playing of the video do not start! Waiting for the
94 download, but I do not get to see the video? Some testing later, I
95 discover that I have to add the
controls="true" attribute to be able
96 to get a play button to pres to start the video. Adding
97 autoplay="true" did not help. I sure hope this is a misfeature of the
98 test version of Opera, and that future implementations of the
99 <video
> tag will stream recordings by default, or at least start
100 playing when the download is done.
</p>
102 <p>The test page I used (since changed to add more attributes) is
103 <a href=
"http://www.nuug.no/aktiviteter/20090113-foredrag-om-foredrag/">available
104 from the nuug site
</a>. Will have to test it with the new Firefox
107 <p>In the test process, I discovered a missing feature. I was unable
108 to find a way to get the URL of the playing video out of Opera, so I
109 am not quite sure it picked the Ogg Theora version of the video. I
110 sure hope it was using the announced Ogg Theora support. :)

139 spesifikasjoner overordnet styrt av xiph.org, som er en
140 ikke-kommersiell organisasjon. Etablerte og anerkjente
141 standardiseringsorganisasjoner, som Oasis, W3C og Ecma, har en godt
142 innarbeidet vedlikeholds- og forvaltningsprosess av en standard.
143 Det er derimot helt opp til hver enkelt organisasjon å bestemme
144 hvordan tekniske spesifikasjoner videreutvikles og endres, og disse
145 spesifikasjonene bør derfor ikke defineres som åpne
146 standarder."</blockquote></p>
148 <p>De vokter seg vel for å nevne den anerkjente
149 standardiseringsorganisasjonen IETF, som er organisasjonen bak HTTP,
150 IP og det meste av protokoller på Internet, og RFC-standardene som
151 IETF står bak. Ogg er spesifisert i
152 <a href=
"http://ietf.org/rfc/rfc3533.txt">RFC
3533</a>, og er uten
153 tvil å anse som en åpen standard. Vorbis er
154 <a href=

159 skrevet i stein ennå, men det blir neppe endringer som ikke er

161 jeg ikke finner tegn til at

162 href=
"http://flac.sourceforge.net/format.html">spesifikasjonen

164 standardiseringsorganisasjon, men i og med at folkene bak Ogg, Theora
165 og Vorbis også har involvert seg i Flac siden
2003, så ser jeg ikke
166 bort fra at også den organiseres via IETF. Jeg kjenner personlig lite

170 spesielt når det er så enkelt i dagens Internet-hverdag å gå

197 faktisk var vedtatt etter

</a>.
199 De fleste av de valgte åpne standardene er gode og vil bidra til at
200 alle kan delta på like vilkår i å lage løsninger for staten, men
201 noen av dem blokkerer for de som ikke har anledning til å benytte
202 spesifikasjoner som krever betaling for bruk (såkalt
203 royalty-betaling). Det gjelder spesifikt for H
.264 for video og MP3
204 for lyd. Så lenge bruk av disse var valgfritt mens Ogg Theora og Ogg
205 Vorbis var påkrevd, kunne alle som ønsket å spille av video og lyd
206 fra statens websider gjøre dette uten å måtte bruke programmer der
207 betaling for bruk var nødvendig. Når det nå er gjort valgfritt for
208 de statlige etatene å bruke enten H
.264 eller Theora (og MP3 eler
209 Vorbis), så vil en bli tvunget til å forholde seg til
210 royalty-belastede standarder for å få tilgang til videoen og
213 <p>Det gjør meg veldig trist at regjeringen har forlatt prinsippet om
214 at alle standarder som ble valgt til å være påkrevd i katalogen skulle
215 være uten royalty-betaling. Jeg håper det ikke betyr at en har mistet
216 all forståelse for hvilke prinsipper som må følges for å oppnå
217 likeverdig konkurranse mellom aktørene i IT-bransjen. NUUG advarte

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

">Some notes on Flash in Debian and Debian Edu</a>
281 <p>In the <a href="http://popcon.debian.org/unknown/by_vote
">Debian
282 popularity-contest numbers</a>, the adobe-flashplugin package the
283 second most popular used package that is missing in Debian. The sixth
284 most popular is flashplayer-mozilla. This is a clear indication that
285 working flash is important for Debian users. Around 10 percent of the
286 users submitting data to popcon.debian.org have this package
289 <p>In the report written by Lars Risan in August 2008
290 («<a href="http://wiki.skolelinux.no/Dokumentasjon/Rapporter?action=AttachFile&do=view&target=Skolelinux_i_bruk_rapport_1.0.pdf
">Skolelinux
291 i bruk – Rapport for Hurum kommune, Universitetet i Agder og
292 stiftelsen SLX Debian Labs</a>»), one of the most important problems
293 schools experienced with <a href="http://www.skolelinux.org/
">Debian
294 Edu/Skolelinux</a> was the lack of working Flash. A lot of educational
295 web sites require Flash to work, and lacking working Flash support in
296 the web browser and the problems with installing it was perceived as a
297 good reason to stay with Windows.</p>
299 <p>I once saw a funny and sad comment in a web forum, where Linux was
300 said to be the retarded cousin that did not really understand
301 everything you told him but could work fairly well. This was a
302 comment regarding the problems Linux have with proprietary formats and
303 non-standard web pages, and is sad because it exposes a fairly common
304 understanding of whose fault it is if web pages that only work in for
305 example Internet Explorer 6 fail to work on Firefox, and funny because
306 it explain very well how annoying it is for users when Linux
307 distributions do not work with the documents they receive or the web
308 pages they want to visit.</p>
310 <p>This is part of the reason why I believe it is important for Debian
311 and Debian Edu to have a well working Flash implementation in the
312 distribution, to get at least popular sites as Youtube and Google
313 Video to working out of the box. For Squeeze, Debian have the chance
314 to include the latest version of Gnash that will make this happen, as
315 the new release 0.8.8 was published a few weeks ago and is resting in
316 unstable. The new version work with more sites that version 0.8.7.
317 The Gnash maintainers have asked for a freeze exception, but the
318 release team have not had time to reply to it yet. I hope they agree
319 with me that Flash is important for the Debian desktop users, and thus
320 accept the new package into Squeeze.</p>

">Terms of use for video produced by a Canon IXUS 130 digital camera</a>
341 <p>A few days ago I had the mixed pleasure of bying a new digital
342 camera, a Canon IXUS 130. It was instructive and very disturbing to
343 be able to verify that also this camera producer have the nerve to
344 specify how I can or can not use the videos produced with the camera.
345 Even thought I was aware of the issue, the options with new cameras
346 are limited and I ended up bying the camera anyway. What is the
347 problem, you might ask? It is software patents, MPEG-4, H.264 and the
348 MPEG-LA that is the problem, and our right to record our experiences
349 without asking for permissions that is at risk.
351 <p>On page 27 of the Danish instruction manual, this section is
355 <p>This product is licensed under AT&T patents for the MPEG-4 standard
356 and may be used for encoding MPEG-4 compliant video and/or decoding
357 MPEG-4 compliant video that was encoded only (1) for a personal and
358 non-commercial purpose or (2) by a video provider licensed under the
359 AT&T patents to provide MPEG-4 compliant video.</p>
361 <p>No license is granted or implied for any other use for MPEG-4
365 <p>In short, the camera producer have chosen to use technology
366 (MPEG-4/H.264) that is only provided if I used it for personal and
367 non-commercial purposes, or ask for permission from the organisations
368 holding the knowledge monopoly (patent) for technology used.</p>

401 <p><a href="http://www.getgnash.org/
">The Gnash project</a> is the
402 most promising solution for a Free Software Flash implementation. It
403 has done great so far, but there is still far to go, and recently its
404 funding has dried up. I believe AVM2 support in Gnash is vital to the
405 continued progress of the project, as more and more sites show up with
406 AVM2 flash files.</p>
408 <p>To try to get funding for developing such support, I have started
409 <a href="http://www.pledgebank.com/gnash-avm2
">a pledge</a> with the
414 <p>"I will pay
100$ to the Gnash project to develop AVM2 support but
415 only if
10 other people will do the same.
"</p>
417 <p>- Petter Reinholdtsen, free software developer</p>
419 <p>Deadline to sign up by: 24th December 2010</p>
421 <p>The Gnash project need to get support for the new Flash file
422 format AVM2 to work with a lot of sites using Flash on the
423 web. Gnash already work with a lot of Flash sites using the old AVM1
424 format, but more and more sites are using the AVM2 format these
425 days. The project web page is available from
426 http://www.getgnash.org/ . Gnash is a free software implementation
427 of Adobe Flash, allowing those of us that do not accept the terms of
428 the Adobe Flash license to get access to Flash sites.</p>
430 <p>The project need funding to get developers to put aside enough
431 time to develop the AVM2 support, and this pledge is my way to try
432 to get this to happen.</p>
434 <p>The project accept donations via the OpenMediaNow foundation,
435 <a href="http://www.openmedianow.org/?q=node/
32">http://www.openmedianow.org/?q=node/32</a> .</p>
439 <p>I hope you will support this effort too. I hope more than 10
440 people will participate to make this happen. The more money the
441 project gets, the more features it can develop using these funds.

472 <p>On the #gnash IRC channel on irc.freenode.net, I was just tipped
473 about what appear to be a great code coverage tool capable of
474 generating code coverage stats without any changes to the source code.
476 <a href="http://simonkagstrom.github.com/kcov/index.html
">kcov</a>,
477 and can be used using <tt>kcov <directory> <binary></tt>.
478 It is missing in Debian, but the git source built just fine in Squeeze
479 after I installed libelf-dev, libdwarf-dev, pkg-config and
480 libglib2.0-dev. Failed to build in Lenny, but suspect that is
481 solvable. I hope kcov make it into Debian soon.</p>
483 <p>Finally found time to wrap up the release notes for <a
484 href="http://lists.debian.org/debian-edu-announce/
2010/
10/msg00002.html
">a
485 new alpha release of Debian Edu</a>, and just published the second
486 alpha test release of the Squeeze based Debian Edu /
487 <a href="http://www.skolelinux.org/
">Skolelinux</a>
488 release. Give it a try if you need a complete linux solution for your
489 school, including central infrastructure server, workstations, thin
490 client servers and diskless workstations. A nice touch added
491 yesterday is RDP support on the thin client servers, for windows
492 clients to get a Linux desktop on request.</p>

</p>
593 <p>Godt å se at du er enig i at dette er en interessant diskusjon. Den
594 vil nok fortsette en stund til. :)
</p>
596 <p>Må innrømme at jeg synes det er merkelig å lese at dere i NRK med
597 vitende og vilje ønsker å forlede rettighetshaverne for å kunne
598 fortsette å legge ut arkivmateriale.
</p>
600 <p>Kommentarer og diskusjoner i bloggene til NRK Beta påvirker jo ikke
601 faktum, som er at streaming er det samme som nedlasting, og at innhold
602 som er lagt ut på nett kan lagres lokalt for avspilling når en ønsker
605 <p>Det du sier er jo at klarering av arkivmateriale for publisering på
606 web krever at en holder faktum skjult fra debattfeltet på NRKBeta.
607 Det er ikke et argument som holder vann. :)

</p>
613 <p>Personlig ønsker jeg at NRK skal slutte å stikke hodet i sanden og
614 heller være åpne på hvordan virkeligheten fungerer, samt ta opp kampen
615 mot de som vil låse kulturen inne. Jeg synes det er en skam at NRK
616 godtar å forlede publikum. Ville heller at NRK krever at innhold som
617 skal sendes skal være uten bruksbegresninger og kan publiseres i
618 formater som heller ikke har bruksbegresninger (bruksbegresningene til
619 H
.264 burde få varselbjellene i NRK til å ringe).
</p>
621 <p>At NRK er med på DRM-tåkeleggingen og at det kommer feilaktive
622 påstander om at "streaming beskytter mot nedlasting" som bare er egnet
623 til å bygge opp om en myte som er skadelig for samfunnet som helhet.

630 <p>Hvis dette innebærer at NRK må være åpne med at arkivmaterialet ikke
631 kan brukes før rettighetshaverene også innser at de er med på å skade

"http://people.skolelinux.org/pere/blog/Why_isn_t_Debian_Edu_using_VLC_.html">Why isn't Debian Edu using VLC?
</a>
674 <p>In the latest issue of Linux Journal, the readers choices were
675 presented, and the winner among the multimedia player were VLC.
676 Personally, I like VLC, and it is my player of choice when I first try
677 to play a video file or stream. Only if VLC fail will I drag out
678 gmplayer to see if it can do better. The reason is mostly the failure
679 model and trust. When VLC fail, it normally pop up a error message
680 reporting the problem. When mplayer fail, it normally segfault or
681 just hangs. The latter failure mode drain my trust in the program.
<p>
683 <p>But even if VLC is my player of choice, we have choosen to use
684 mplayer in
<a href=
"http://www.skolelinux.org/">Debian
685 Edu/Skolelinux
</a>. The reason is simple. We need a good browser
686 plugin to play web videos seamlessly, and the VLC browser plugin is
687 not very good. For example, it lack in-line control buttons, so there
688 is no way for the user to pause the video. Also, when I
689 <a href=
"http://wiki.debian.org/DebianEdu/BrowserMultimedia">last
690 tested the browser plugins
</a> available in Debian, the VLC plugin
691 failed on several video pages where mplayer based plugins worked. If
692 the browser plugin for VLC was as good as the gecko-mediaplayer
693 package (which uses mplayer), we would switch.
</P>
695 <p>While VLC is a good player, its user interface is slightly
696 annoying. The most annoying feature is its inconsistent use of
697 keyboard shortcuts. When the player is in full screen mode, its
698 shortcuts are different from when it is playing the video in a window.
699 For example, space only work as pause when in full screen mode. I
700 wish it had consisten shortcuts and that space also would work when in
701 window mode. Another nice shortcut in gmplayer is [enter] to restart
702 the current video. It is very nice when playing short videos from the
703 web and want to restart it when new people arrive to have a look at
704 what is going on.

</a>
752 <p>While at Debconf11, I have several times during discussions
753 mentioned the issues I believe should be improved in Debian for its
754 desktop to be useful for more people. The use case for this is my
755 parents, which are currently running Kubuntu which solve the
758 <p>I suspect these four missing features are not very hard to
759 implement. After all, they are present in Ubuntu, so if we wanted to
760 do this in Debian we would have a source.
</p>
764 <li><strong>Simple GUI based upgrade of packages.
</strong> When there
765 are new packages available for upgrades, a icon in the KDE status bar
766 indicate this, and clicking on it will activate the simple upgrade
767 tool to handle it. I have no problem guiding both of my parents
768 through the process over the phone. If a kernel reboot is required,
769 this too is indicated by the status bars and the upgrade tool. Last
770 time I checked, nothing with the same features was working in KDE in
773 <li><strong>Simple handling of missing Firefox browser
774 plugins.
</strong> When the browser encounter a MIME type it do not
775 currently have a handler for, it will ask the user if the system
776 should search for a package that would add support for this MIME type,
777 and if the user say yes, the APT sources will be searched for packages
778 advertising the MIME type in their control file (visible in the
779 Packages file in the APT archive). If one or more packages are found,
780 it is a simple click of the mouse to add support for the missing mime
781 type. If the package require the user to accept some non-free
782 license, this is explained to the user. The entire process make it
783 more clear to the user why something do not work in the browser, and
784 make the chances higher for the user to blame the web page authors and
785 not the browser for any missing features.
</li>
787 <li><strong>Simple handling of missing multimedia codec/format
788 handlers.
</strong> When the media players encounter a format or codec
789 it is not supporting, a dialog pop up asking the user if the system
790 should search for a package that would add support for it. This
791 happen with things like MP3, Windows Media or H
.264. The selection
792 and installation procedure is very similar to the Firefox browser
793 plugin handling. This is as far as I know implemented using a
794 gstreamer hook. The end result is that the user easily get access to
795 the codecs that are present from the APT archives available, while
796 explaining more on why a given format is unsupported by Ubuntu.
</li>
798 <li><strong>Better browser handling of some MIME types.
</strong> When
799 displaying a text/plain file in my Debian browser, it will propose to
800 start emacs to show it. If I remember correctly, when doing the same
801 in Kunbutu it show the file as a text file in the browser. At least I
802 know Opera will show text files within the browser. I much prefer the
803 latter behaviour.
</li>
807 <p>There are other nice features as well, like the simplified suite
808 upgrader, but given that I am the one mostly doing the dist-upgrade,
809 it do not matter much.
</p>
811 <p>I really hope we could get these features in place for the next
812 Debian release. It would require the coordinated effort of several
813 maintainers, but would make the end user experience a lot better.

</a>
834 <p>Ofte har jeg lyst til å laste ned et innslag fra NRKs nettsted for
835 å se det senere når jeg ikke er på nett, eller for å ha det
836 tilgjengelig når jeg en gang i fremtiden ønsker å referere til
837 innslaget selv om NRK har fjernet det fra sine nettsider. I dag fant
838 jeg et lite script som fikser jobben.
</p>
840 <p>Scriptet er laget av Jan Henning Thorsen og tilgjengelig fra
