Le billet précédent est agrémenté d'une petite vidéo. Voici son histoire, ou comment illustrer ses billets de vidéos en utilisant des formats ouverts.

Au cas présent il s'agit de cette vidéo hébergée sur YouTube et intitulée « Aldo Maccione" la classe" ».
Pour récupérer cette vidéo sous GNU/Linux, il vous suffit d'aller chercher le fichier correspondant dans le répertoire /tmp de votre système une fois la vidéo intégralement chargée dans votre navigateur.

Pour la suite du billet, le fichier aura pour nom « source.flv ».

Pour réencoder la vidéo dans un format ouvert, nous allons utiliser le logiciel libre ffmpeg2theora, disponible sous la licence GNU GPL pour systèmes GNU/Linux, MacOS et Windows.

Comme indiqué précédemment, la résolution et le débit de la vidéo sont à choisir en fonction du type de vidéo. Au cas présent j'ai choisi un encodage à débit constant de 300 kbit/s qui est un débit particulièrement faible compte tenu que la séquence est un film de 320x192 pixels mais qui m'a paru – de façon complètement empirique – suffisant en l'espèce si l'on considère que la scène est assez peu animée et que les images composant la vidéo ont finalement assez peu de différences (le principe de base de la compression vidéo consiste à n'enregistrer complètement que quelques images clés appelées « trames I » puis à enregistrer les seules différences entre deux images clés pour composer les images intermédiaires appelées « trames P »).

La séquence présentait des bandes noires horizontales de part et d'autre de l'image qui nuisaient à la bonne intégration de la vidéo dans la page de mon billet. J'ai donc demandé à ffmpeg2theora de supprimer les bords de la vidéo en même temps qu'il la réencodait. L'opération n'est hélas pas automatique, aussi j'ai dû tâtonner pour définir en pixels la taille des bandes à supprimer (cette taille devant par ailleurs être, dans tous les cas, un multiple de deux)

Au final la commande pour réencoder et recadrer la vidéo est la suivante :
ffmpeg2theora -V 300 --croptop 24 --cropbottom 24 source.flv -o fichiertemp.ogg

D'une séquence audio-vidéo de 320x240 pixels encodée dans un format fermé (en H.264/AVC Video pour la vidéo et MPEG-4 AAC pour l'audio) nommée « source.flv », on passe à une séquence audio-vidéo recadrée en 320x192 pixels dans un format ouvert (Ogg Theora à débit constant de 300 kbit/s pour la vidéo, et Ogg Vorbis pour l'audio) nommée « fichiertemp.ogg ».

A noter qu'un encodage en deux passes (au lieu d'une comme dans l'exemple ci-dessus), toujours à débit constant, vous permettrait d'optimiser la qualité de la vidéo.

En savoir plus : consulter les commandes pour ffmpeg2theora ici et là.

La séquence téléchargée depuis YouTube et réencodée au format Ogg est en fait une compilation de plusieurs séquences différentes. Nous allons extraire le tronçon qui nous intéresse et qui correspond grosso modo aux huit première secondes.

Nous utiliserons pour cela les Ogg Video Tools (et spécialement l'outil oggCut), un logiciel disponible sous la licence GNU GPL pour systèmes GNU/Linux, MacOS et Windows.

A noter que le tronçonnage va être effectué sans recompression, donc très rapidement et sans perte de qualité. Les indications temporelles sont exprimées en millisecondes. Elles sont toutefois indicatives dans la mesure où le logiciel ne coupera qu'aux endroits des « trames I ».

La commande pour extraire la première séquence de la vidéo est :
oggCut -s 0 -e 8140 fichiertemp.ogg destination.ogg

D'une séquence audio-vidéo de presque trois minutes nommée « fichiertemp.ogg » on ne conserve que le début en un séquence nommée « destination.ogg ».

En savoir plus : voir les commandes pour les Ogg Video Tools.

L'intégration de la vidéo ainsi obtenue dans la page Web se fait au moyen des balises multimédias de HTML5 (un format ouvert).

A noter que la spécification HTML5 permet d'utiliser, au sein de la balise video, l'attribut poster pour spécifier une image à afficher en attendant que l'utilisateur ne lance la vidéo (si vous n'avez pas défini cet attribut alors c'est la première image de la vidéo qui sera affichée par défaut). Firefox 3.6 supporte cette fonctionnalité et il semblerait que ce soit le cas également d'Opera 10.50. En revanche les autres navigateurs compatibles HTML5 remplaceraient automatiquement cette image par la première image de la vidéo.

Sur le billet dont il s'agit, voici ce que vous voyez suivant que l'attribut n'est pas pris en compte (première capture, effectuée sous Firefox 3.5) ou l'est (deuxième capture, sous Firefox 3.6) :

Pour ma part je bénéficie de mon propre espace d'hébergement pour mon blogue sur le Web (lire ce précédent billet) de sorte qu'il me suffit d'y ajouter les séquences audio/vidéo pour les utiliser sur mon blogue. Sinon il existe des services d'hébergement de vidéos au format Ogg Theora.

Affirmatif. Quand bien même l'Å“uvre sur laquelle vous avez jeté votre dévolu n'autoriserait pas expressément et préalablement sa libre utilisation (au moyen d'une licence type Creative Commons), vous êtes autorisé par la loi à en reproduire à de courts extraits (c'est le droit de courte citation, une exception légale aux droits d'auteur).

Si vous avez mis en Å“uvre les différentes étapes décrites dans ce billet, vous devriez avoir noté différentes choses :

• L'encodage en Theora se fait à la vitesse de la lumière : c'est un des encodeurs les plus rapides de sa catégorie (certainement le plus rapide)
• La taille du fichier vidéo obtenu est particulièrement réduite : moins de 350 Kio quand même pour une vidéo de huit secondes !
• Malgré la vitesse élevée d'encodage et la très petite taille du fichier obtenu, la qualité de la vidéo est tout à fait satisfaisante (alors qu'il s'agit d'un réencodage !)

Qui a dit que Theora n'était pas un codec adapté au Web ?

Mozilla platform engineer Rob Sayre has probably had better ideas.

Hoping Microsoft might allow Firefox on their new Windows Phone 7 Series, Sayre wrote an open letter this morning to Microsoft CEO Steve Ballmer. “Hola, amigo. I know it’s been a long time since I rapped at ya,” is how it starts.

He then proceeds to make fun of Windows Phone 7 Series, the iPhone, Cocoa Touch, and Unix — all in three concise paragraphs. He notes that Windows Phone 7 Series has a “busted” UI, calls the iPhone’s UI “ugly jelly beans,” and mocks the “allegedly cool” Cocoa Touch “stuff.”

Once he’s done with all of that, he asks Ballmer to consider making an NDK for Windows Phone. An NDK is a companion tool for an SDK that allows you to build parts of apps in native code. For example, it’s the Android NDK that allows Mozilla to make Firefox for Android.

There’s currently no plans to make an NDK for Windows Phone 7 phones — hence Sayre’s post. Without it, a version of Firefox for the OS is probably unlikely. And that’s may be a good bet anyway, considering Microsoft seems to be pivoting its new phones closer to the iPhone’s closed model rather than Android’s open one.

Sayre’s approach to the post apparently didn’t go over too well — he quickly followed up with an apology post, “Things I’ve Learned.” “Blog posts that sound like Jim Anchower really irritate people for some reason. I won’t do it again, I promise,” he writes.

Siguiendo con su calendario, Canonical ya ha sacado la primera beta de Ubuntu 10.04 Lucid Lynx, junto con las correspondientes versiones de Kubuntu, Xubuntu y Lubuntu.

En esta versión se incluyen las últimas versiones de GNOME (2.28), KDE (4.4) y del kernel Linux (2.6.32-16.25). Además, se introducen otros cambios importantes, como el del motor de búsqueda por defecto de Firefox, que pasa a ser Yahoo!; la inclusión del driver libre de nVidia por defecto en lugar del propietario, integración con redes sociales, un nuevo tema y menor tiempo de arranque.

En la versión Kubuntu, encontramos una versión de Plasma específica para netbooks, una presentación de diapositivas que se muestra durante la instalación, al más puro estilo Windows, mejor soporte con touchpads de portátiles, y algo muy interesante, mejor integración de Firefox con KDE.

Esta es todavía una versión Beta, con fallos conocidos, y que solo debería ser usada para reportar fallos. La versión final está prevista para el 29 de abril.

Suite à une dépêche sur LinuxFr j’ai décidé de réessayé CairoDock dont j’avais un très mauvais souvenir... et il faut dire que depuis je suis totalement fan !

Le voici en vidéo (je me suis un peu raté dans le montage à la fin ) :

Prenez un navigateur moderne (Firefox, Chromium, ...) ou allez sur cette page. (ou alors c’est Wordpress qui m’a encore enlever la balise video... )

(J’en profite pour vous recommender l’excellent The Dada Weatherman.)

Voici ce que j’ai fait pour arriver à ça :

• J’utilise la version 2.1.4-0alpha1 (grâce à leur ppa).
• J’ai activé les plug-ins : «Â Afficher le bureau », «Â Déconnexion », «Â Dnd2share », «Â GMenu », «Â Horloge », «Â Poubelle », «Â PowerManager » et «Â systray ». Et j’ai crée des sous-dock pour y stocker des raccourcis et des plugins (vive le glisser-déposer et le «Â Déplacer vers un autre dock »)
• Je suis parti du thème «Â Humanity-Dock » pour arriver à ce thème modifié (packagé à La Rache) à placer dans .config/cairo-dock/themes.
• J’ai écrit un petit script au qui se lance au démarrage pour résoudre quelques problèmes : #!/bin/sh compiz --replace & # Non avec les réglages gconf ca ne fonctionne pas... gconftool-2 -s '/apps/panel/general/toplevel_id_list' --type liste --list-type string [] #Pour enlever le panel (il se remet à chaque fois...) cairo-dock -c & # Pour lancer Cairo-dock sans OpenGL

Voilà c’est tout simple .
Petite dédicace aux développeurs de CairoDock qui m’ont bien aidé sur le forum malgré que je n’arrivais vraiment pas à résoudre certains problèmes... et à leur courage pour développer CairoDock (surtout ce foutu systray ).
PS : Vous remarquerez que j’ai mis le systray en haut à gauche : il ne bloque pas l’expansion des fenêtres et ne cache rien d’utile (sauf dans Lucid Lynx où il faudra le mettre à droite ).

No really. I prefer GNOME, so clearly pretty isn’t the biggest factor here. When I first started using Ubuntu, I would drag the top GNOME panel to the bottom and have  it sit under what is normally the bottom panel. It looked ugly as sin, but this is how, as (back in 2005) a recent Windows refugee, I was used to working and so this is how I chose to organise my space.

Most importantly, it wasn’t hard for me to do this. My most recent installs, almost 4 years later, primarily on laptops rather than desktops tended to be left as is — a panel at the top  and a panel at the bottom. I find this seems to suit laptops better, and I’ve become accustomed to it. However, had I not been able to move the panel from the start, I might even have ended up on Kubuntu. Well, if it were not for the silly single-click thing that fires stuff off even when you don’t want it to, like when you bump the mouse accidentally. Ok, truth be told, I probably would have stuck with Ubuntu, because, well, all the functionality was still there. Just in a different place to where I was expecting

As with most computer users, I’ve never owned a Mac. When I was little, my school had a some (iirc) Mac II’s but I am pretty certain that the number of times that I, at 28, have used a Mac since would barely exceed the number of digits on my hands, and OS X is nothing like the first Macs I used. I think the last time I used a Mac was in 2005; for about 20 minutes.

But now with the sneaky Lucid UI changes, I might as well be using OS X as far as my learned behaviours are concerned. And lets just hope that my laptop trackpad doesn’t jump at an inopportune time — like it does sometimes when I go to open the system menu and instead hit the firefox icon right next to it instead — as trackpads are prone to.

I work 100% from a laptop and use the trackpad 90% of the time. The chance this ridiculous UI change will not bite me hard is pretty slim. The only plus I’ve come across so far is that it made it easier to close out of the awkwardly oversized evolution setup wizard that launched on my eeepc701.

However, putting even that glaring risk aside, the one thing that I am absolutely hating the most about these sneaky UI changes is the abolishment of informative tooltips. This is a loss of functionality.

My battery icon, my wifi connection icon, my xchat icon — they now tell me nothing when I merely nudge them, I now have to smack them over the head with the cursor. I cannot tell at quick glance if I have enough charge for something, on the wrong wifi network, or whether I can ignore that xchat message I missed the notification for. I have to exert time, energy, and most importantly brain focus to get what used to be a simple matter of an effortless enlightenment. I now have to go through what is sometimes several clicks. Extra clicks are bad. Clicks add obscurity. Extra clicks are effort.

This bleeps me right off. I can learn to move a mouse in a different direction (though I’m not at all believing that new windows migrants will cope), but I really do not have the capacity to circumvent the application to read the bytes from the disk myself to find out what my battery level is without clicking through some dialogs. The software is supposed to do that for me.

Alas, my software no longer does this for me, and ergo, my software no longer works for me.

To get this information, I now have to do stuff for my software. I should not be working for my software.

Mozilla knows that they have an unpatched flaw in their browser, and has promised to address the issue before the month is over. This flaw was recently discovered by security researcher Evgeny Legerov, where one is able to create a means to inject hostile code on vulnerable systems. Expect the fix to come in version 3.6 of Firefox this coming March 30th. If you can't wait and have the technical proficiency to do so, then you can always go ahead with the beta version of the 3.6.2 release that already plugs this flaw.

Back in June, Google launched Sputnik, a suite of tools that runs over 5,000 tests to check a web browser’s JavaScript conformance. Last week, they made the tool a lot easier for anyone to use, with a version that works in the web browser. The results are interesting.

Notably, both the Opera and Safari web browsers beat Google’s own Chrome browser in the test. As you can see in the picture above, Opera is the clear leader, with only 78 failures (the closer to the center, the less errors). Safari came in second with 159 errors, with Chrome in third with 218 errors. Firefox is close behind with 259 errors, while Internet Explorer is the outlier with 463 errors.

These tests were run on Windows machines, with the latest released version of each browser. Using the web tool on my Mac, though, shows similar results (at least for Opera, Chrome, Safari, and Firefox — there is no IE for Mac anymore).

While much of the focus on JavaScript is about speed (that’s what the SunSpider test measures, for example), Sputnik is interesting because it focuses on conformity, making it more like the Acid3 test, which tests web standards compliance. Chrome, Safari, and Opera have all passed Acid3, with Firefox getting very close (94/100 for Firefox 3.6). IE, meanwhile, again lags behind with just 20/100 for IE8. And even the new IE9 preview only scores 55/100.

Speaking of IE9, I tried to run the Sputnik tool in the preview build of the new browser on Windows 7. Unfortunately, it completely shut down several times after getting up to about 50 failures after only a few hundred of the 5,000+ tests — not a good sign. But again, it’s just a very early preview release of the browser, and early SunSpider results for the browser have been good.

The Ubuntu team is pleased to announce the first beta release of Ubuntu 10.04 LTS (Long-Term Support) Desktop, Server, and Netbook editions and of Ubuntu 10.04 Server for Ubuntu Enterprise Cloud (UEC) and Amazon’s EC2. Codenamed "Lucid Lynx", 10.04 LTS continues Ubuntu’s proud tradition of integrating the latest and greatest open source technologies into a high-quality, easy-to-use Linux distribution.

Ubuntu 10.04 LTS Desktop and Netbook Editions continue the trend of ever-faster boot speeds, with improved startup times and a streamlined, smoother boot experience.

Ubuntu 10.04 LTS Server Edition provides even better integration of the Ubuntu Enterprise Cloud, with its install-time cloud setup.

Ubuntu 10.04 LTS Server for UEC and EC2 brings the power and stability of the Ubuntu Server Edition to cloud computing, whether you’re using Amazon EC2 or your own Ubuntu Enterprise Cloud.

The Ubuntu 10.04 family of variants, Kubuntu, Xubuntu, Edubuntu, Ubuntu Studio, and Mythbuntu, also reach beta status today.

Desktop features
————————

Social from the start: We now feature built-in integration with Twitter, identi.ca, Facebook, and other social networks with the MeMenu in the panel.

New Design: Cleaner and faster boot, new notification area, new themes, new icons, and new wallpaper bring a dramatically updated look and feel to Ubuntu.

Ubuntu One: Choose any folder in your home directory to sync, choose from millions of songs for purchase in the Ubuntu One Music store.

Please see http://www.ubuntu.com/testing/lucid/beta1 for details.

Server features
———————-

Cloud computing: The Ubuntu Enterprise Cloud installer has been vastly improved in order to support alternative installation topologies. UEC components are now automatically discovered and registered, even with complex topologies. Finally, UEC is now powered by Eucalyptus 1.6.2 codebase.

UEC and EC2: Ubuntu 10.04 LTS continues the tradition of official Ubuntu Server image releases for UEC and for Amazon’s EC2, giving you everything you need for rapid deployment of Ubuntu instances in a cloud computing environment. UEC images, and information on running Ubuntu 10.04 on EC2, are available at:

http://uec-images.ubuntu.com/releases/10.04/beta1

Stability and security: Ubuntu 10.04 LTS brings many improvements over Ubuntu 8.04 LTS to keep your servers safe and secure for the next five years, including AppArmor profiles for many key services, kernel hardening, and an easy-to-configure firewall.

Ubuntu Netbook features
———————————-
Ubuntu Netbook Edition is optimised to run on Intel atom based netbooks. It includes a new consumer-friendly interface that allows users to quickly and easily get on-line and use their favourite applications. This interface is optimised for a retail sales environment.

It includes the same faster boot times and improved boot experience as Ubuntu desktop.

Kubuntu features
————————

Kubuntu 10.04 LTS will be the first LTS to feature KDE 4 Platform and Applications. KDE 4 has come a long way since its early releases and is now suitable for the high demands of LTS users. Being an LTS we have focused on bug fixing and stability for this release, but we did find time to add features such as touchpad configuration, Firefox KDE integration, Kubuntu notification improvements, and cross-desktop systray menu standardisation. Kubuntu features the Plasma Desktop while Kubuntu Netbook Remix comes out of preview status with the Plasma Netbook workspace.

See https://wiki.kubuntu.org/LucidLynx/Beta1/Kubuntu for more details.

Edubuntu features
————————-

Edubuntu in Lucid features a more complete live environment containing more software from universe and all existing language packs as well as our usual educational software in their current version. For Lucid the text installer has been removed and so is LTSP for the time being. We expect to have LTSP back on the DVD for the next beta. The DVD is then much smaller than it used to be but will still provide a complete education environment based on Ubuntu Lucid.

Also included on the Edubuntu DVD is a small repository containing the required packages to transform the regular Edubuntu desktop into a LTSP server or install the Netbook edition interface.

Mythbuntu features
—————————

Mythbuntu 10.04 introduces MythTV 0.23. This new version is significantly faster and should feel more responsive and stable than older versions. It also integrates better into the OS with better support for things like ConsoleKit and Upstart.

Please see http://www.mythtv.org/wiki/Release_Notes_-_0.23 for more details about changes introduced in 0.23.

See http://mythbuntu.org/10.04/beta for information about the Mythbuntu beta release.

Other
——-
