For a while I have been searching for a tool that would allow me to encode movies in Linux. I knew about ffmpeg but I was a little upset with Ubuntu because the ffmpeg application was not compiled to function with none free codecs. Those codecs might be: x264, mp3 among others codecs and containers like MP4.

Well the good news is that in Linux we do not need all those containers and Junk. I discover, and I know this is not new, that it is good enough with Theora/Vorbis. I know that there are other GUI tools to do all the encoding, but for some reason, I am happy enough with he fact that I can use a tool like ffmpeg to do the job of free and open source software. I got to tell you, it is neat and fast. Here is the command that I would use to encode any file into Theora/Vorbis video file: ffmpeg -i input.file -vcodec libtheora -ac 2 -acodec vorbis output.ogv

It is this simple. For more information you can always “man ffmpeg” command and learn more about it. One last thing, I usually like to rip the audio of any videos to put it on my Personal Media Player (PMP) and I would need to rip the audio and put it in Vorbis or OGG format. If you want to do that the command is: ffmpeg -i input.file -vn -ac 2 -acodec vorbis output.ogg

This should work. The reason why I am writing this is because the community is always giving me so much, this is just a way for me to give back to the community.

Until later.

オープンソースの技術を心から支持している私たちは、Firefox が新しい HTML の動画タグにこの夏から対応し始めたことにとても喜んでいました。この技術は将来のオンライン動画を根本的に変貌させる可能性を秘めている思っています。

動画タグへの全面対応は現在まだ作業の途中です。しかし、既にアップロードされている動画はすべて（通常の mp4 形式に加え）Theora/Ogg 形式でのエンコードが完了しました ! VideoPress* ユーザーは、メディアライブラリから Ogg ファイルの URL を取得できるようになっており、これらの動画は Firefox 3.5や Chrome などの HTML 5対応ブラウザから直接再生できます。

Firefox 3.5 でサンプル動画をご覧ください。

* VideoPress を使えば、HD クオリティの動画を挿入できます。

この記事は Hailin が WordPress.com 英語版ブログに投稿した「VideoPress Supports Ogg」の訳です。本文内のリンクはすべて英語です。

Fervorosos defensores de tecnologias de código aberto que somos, ficámos muito contentes quando o Firefox começou a suportar o novo tag HTML de vídeo no verão passado. Ele tem o potencial para transformar o futuro do vídeo online.

Enquanto ainda estamos a trabalhar para suportar completamente o novo tag de vídeo, é com muito prazer que anunciamos que temos já codificado todo o nosso inventário em formato Theora/Ogg, além do habitual mp4. Os utilizadores de Videopress podem aceder à URL do arquivo Ogg na biblioteca de mídia e o vídeo pode ser reproduzido directamente em browsers que suportem HTML 5, como o Firefox 3.5 e o Chrome. Tente abrir este vídeo com Firefox 3.5!

Google Chrome linux version playing Ogg theora video file

Google making braking news in every morning in recent times. All the geeks digging for google wave, chrome browser, chromesOS, leaked ChromeOS running top of ubuntu etc….

In the latest developing version of google chrome for linux platform [v4.222.5], it integrated html 5 audio/video support. It is very surprising chrome also support and playerd other multimedia formats than HTML 5 standard’s. Beacasue of HTML 5 support chrome naturally played Ogg theora and ogg vorbis (.ogg/.ogv) just like other browsers in the league. But supporting other multimedia formats like mp3 and mp4 is very surprising. In my test it support and playing Ogg,ogm,mp3 and mp4 without third party plugin support, even from local hadrdisk. But mp4 is supported but not played well. Other formats like wmv,wma,and avi is not supported without plugins.

Martes sin X comienza con Shrip.

Shrip es la version CLI de OGMRip, utileria para ripear respaldar DVD de video, que utiliza herramientas como mplayer, mencoder, mkvtoolnix, mp4box, oggenc, lame, faac. Entre las caracteristicas de este programa se encuentra soporte para multiples formatos de salida (OGM, AVI, MP4, MKV), soporte para diversos codecs (Mp3, Vorbis, X264, XviD, Theora, etc), extraccion de subtitulos, deteccion automatica la escala del video y mas.

Un comando seria:

shrip encode -t 1 -a 01 -C mp4 -V x264 -A aac /directorio/de/salida.mp4

Para Ubuntu/Debian pueden usar este paquete deb.

En Arch Linux se encuentra en los repositorio AUR

Espero que les sirva.

Mata ne!

Version 1.1 of the free video library has just been released. The developers did a complete rewrite, which features more quality at the same size, as well as more speed and stability.

source (via t3n)

Come saprete (se non lo sapete leggetevi la pagina su Wikipedia) ogg e’ un formato di file che puo’ contenere vari formati, sia video sia audio sia testo (con i sottotitoli per intenderci) sia misto, e cosa importante, e’ libero. Vediamo quindi come trasformare i nostri file video e audio in formato ogg.

Il pesce di Vorbis non e' muto

Avete un file audio in wav (ma il discorso vale anche per altri formati audio) e lo volete convertire in formato ogg. Tutto quello che ci serve e’ ffmpeg (piu’ i codec che daro’ per scontato abbiate gia’). Da terminale posizioniamoci nella directory contenete il nostro file audio in formato proprietario e scriviamo:
$ ffmpeg -i fileaudio.wav -acodec libvorbis -ab 128k -ac 2 fileaudio.ogg
Nel dettaglio, stiamo dicendo a ffmpeg di prendere il file fileaudio.wav (-i), usando i codec audio libvorbis (-acodec) utilizzando un bitrate audio pari a 128k (-ab), settando il numero di canali a 2 (-ac). E ovviamente creando l’output fileaudio.ogg. Le opzioni possono essere cambiate, magari volete un solo canale audio, o un bitrate differente o che so io.

Ora invece volete convertire il vostro file video da wmv ad ogg. In questo caso useremo le librerie Theora di ffmpeg:
$ ffmpeg -i filevideo.wmv -vcodec libtheora -acodec libvorbis filevideo.ogg
Ecco fatto.

Se volete solo il video senza l’audio:
$ ffmpeg -i filevideo.wmv -vcodec libtheora -an filevideo.ogg
Se invece volete solo l’audio senza il video:
$ ffmpeg -i filevideo.wmv -vn -acodec libvorbis filevideo.ogg
L’opzione -vn dice senza video, quella -an dice senza audio.

Per le varie opzioni e per modificare quelle dell’esempio leggetevi l’output di questo magico comando:
$ man ffmpeg
Ovviamente ffmpeg non e’ l’unico ne’ il miglior metodo di conversione, esistono anche altri sistemi, cercateli.

Inserir vídeos ogg/theora en pàgines html.

Index:

1- Convertir vídeos avi o mpg al format ogg/theora

2- Propietats del vídeo convertit al format *.ogv

3- Baixar l’applet cortado.jar

4- Inserir vídeos ogv amb l’eXelearning que llegirà qualsevol navegador.

5- Inserir vídeos que sols llegirà Firefox.

1- Convertir vídeos avi o mpg al format ogg/theora

Convertir vídeos *.avi o *.mpg al format *.ogv és molt fàcil en Ubuntu i no necessitarem utilitzar controladors privatius si sols volem que els llegisca Firefox.

Instal·la el programa conversor de formats de vídeo ffmpeg amb el gestor de programes synaptic d’Ubuntu ,o amb el gestor de programes adept de Kubuntu o amb la gestor de programes apt-get a la línia de terminal.

Obre un terminal d’ordres amb ALT+F2 i escriu gnome-terminal ( o konsole).

Ves a la carpeta on tens el vídeo *.avi o *.mpg que vols convertir al format *.ogv amb una ordre semblant a

(El teu vídeo està en un lloc diferent , et caldrà canviar el camí).

Per convertir el format del vídeo ara utilitzem el ffmpeg amb l’ordre.

(canvia input.mpg pel nom del fitxer que vols converir, en el meu cas és mov07035.mpg i canvia output.ogv per el nom del fitxer que vols d’eixida en format ogv, en el meu cas mov07035.ogv , així jo he posat com ordre ffmpeg -i mov07035.mpg -vcodec theora -y mov07035.ogv ).

2- Propietats del vídeo convertit al format *.ogv

El vídeo original que he emprat (mov07035.mpg) tenia una mida de 5,4 MB i el vídeo d’eixida (mov07035.ogv) tenia una mida de 1,6 MB , això vol dir que ffmpeg al convertir-lo al format ogg/theora l’ha comprimit un 70,37%, evidentment això ens permet estalviar espai web als servidors on pengem html i ens fa guanyar velocitat quan els alumnes es baixen el vídeos incrustats a les pàgines html (ja sabem que les velocitats d’internet van com van).

Ens cal anotar una propietat del vídeo convertit al format ogv (o del mpg o avi original) , i és la mida del vídeo. Per saber això premem sobre el vídeo ogv amb el botó dret i cerquem les propietats. Anotem en full l’amplada x alçada. ( En el nostre cas 640 x 480 píxels).

3- Baixar l’applet cortado.jar

Ara ens cal baixar l’applet cortador.jar per inserir vídeos ogv i permetre que qualsevol navegador inclòs el Internet Explorer (que no dona suport al format lliure ogg/theora) puga mostrar el nostre vídeo. L’applet cortado.jar el podeu baixar de http://theora.org/cortado.jar .

4- Inserir vídeos ogv amb l’eXelearning que llegirà qualsevol navegador.

Anem a mostrar com inserir vídeos ogv amb l’eXelearning que és editor d’unitats didàctiques adreçat especialment a docents (també per als maldestres) per fer pàgines web.

Prem sobre l’iDevice Aplicació de java a la part esquerre deXelearning.

Prem el botó Afegir arxius (1) , cerca el fitxer cortador.jar a la carpeta on estiga (2) , prem el botó Càrrega (3) , i t’apareixerà carregat dins la teua unitat (4) , repeteix el procediment per carregar el teu vídeo ogv.

Ara cal que copies el codi següent:

Canvia al costat del paràmetre value (1) el nom mov07035.ogv pel del teu vídeo ogv.

Canvia al costat dels paràmetres width , height (2) l’amplada x alçada en pixels que hem anotat abans.

Ja podem alçar la unitat amb el vídeo incrustat. Si exportem la unitat en format htmlzip , SCORM, o IMS podrem veure el vídeo incrustat al moodle del nostre centre.

Ací tens una unitat que utilitze amb els alumnes amb vídeos ogg/theora incrustats.

5- Inserir vídeos que sols llegirà Firefox.

Si no volem utilitzar cap màquina virtual de java jre , també podem incrustar vídeos a les nostres pàgines html però en aquest cas sols el llegirà Firefox i pocs navegadors més.

Ho farem amb les etiquetes de <video> </video> canviant la src del vídeo amb el format següent:

En aquest cas és absolutament recomanable que mireu aquestes fonts.

Font1: https://developer.mozilla.org/en/Using_audio_and_video_in_Firefox

Font2: http://wiki.xiph.org/HTML5

Desde hace tiempo ha sido un objetivo perseguido por muchos,  ya que tanto el plugin Flash Player de Adobe al ser cerrado,  supone un dolor de cabeza para los desarrolladores de los navegadores, ya que en gran parte las fugas de memoria procedían de este plugin. Por otro lado el flash libre “Gnash” aún está muy verde,  y su consumo de RAM en muchos casos es superior.

Desde la versión 3.1 de Firefox (versión preliminar a la estable 3.5) soporta las etiquetas <audio> y <video> de la especificación de HTML5,  que permiten a los desarrolladores web añadir fácilmente (<video src=”Dmiarchivo.ogg”></video>) y contenido multimedia,  sin tener que recurrir a los plugins antes mencionados.

Dailymotion para agrado de muchos entre ellos la FSF (Free Software Foundation) [en] desde hace dos meses da soporte para sus vídeos sin flash y dado que Mozilla Firefox contiene los codecs Ogg Theora y Vorbis. De momento la calidad y el sonido de los vídeos no es equiparable, pero ya veremos como se desarrolla en el futuro y nos han asegurado que lo mejorarán .

Si queréis ver los vídeos desde openvideo.dailymotion.com, primero debéis desactivar en Mozilla Firefox 3.5.x el plugin de flash player, para ello debéis dirigiros al menú Herramientas–> Complementos–> Plugins–> clic derecho sobre “Shockwave Flash”–> botón desactivar -para activarlo seguid los mismos pasos, pero al final pulsad el botón “activar”-.

El catálogo del que dispone Openvideo Dailymotion ya cuenta con cientos de miles de vídeos,  listos para reproducir con el formato Ogg, Theora + Vorbis.

Deseo y espero que otros portales de emisión de vídeos, se sumen a dailymotion, así como otros navegadores,  para mejorar y potenciar este estandar abierto.

I’m not sure who got to it first but Dailymotion, Youtube, and my site (http://NumberedHumanIndustries.com) are the only sites that are using the HTML5 video tag.

Dailymotion’s page is at http://openvideo.dailymotion.com and as far as I can tell is using the Vorbis/Theora Firefox 3.5 compatible spec.

Youtube’s HTML5 site is at http://www.youtube.com/html5 and is using H.264 and doesn’t seem to work in Firefox 3.5

My HTML5 page is http://NumberedHumanIndustries.com/video and it is Vorbis/Theora and works in Firefox 3.5

If you know of any other pages that are using are using the proposed HTML5 video tags please comment here, email me three [at] threethirty [dot] us, or @threethirty on identi.ca

إن صيغة Theora  وكما قرأتم عنها في مقالة سابقة تتحسن باستمرار ، وتقترب في أداءها مع الصيغة التجارية H.264 ، وهو أداء فوق الحاجة لأغراض العرض على مواقع الوب.

ما هي OGG ؟
حسنا ، إن ogg هي صيغة حاوية معيارية حرة ومفتوحة المصدر ترعاها مؤسسة Xiph.org ، وهي غير مقيدة ببراءات اختراع وصممت خصيصا لتقديم جودة عالية في الملتيمديا الرقمية.
انتبه إلى أن ogg  مجرد حاوية ، يمكن أن تحوي عدة صيغ أو codec حرة ومفتوحة للصوت والفيديو.
في بيئة Ogg الملتيمدية : صيغة Theora تقدم طبقة فيديو مضغوطة ، بينما صيغة Vorbis تقدم طبقة صوتية مضغوطة، إذن يمكننا القول أن صيغة Vorbis ogg منافسة لصيغة mp3 لكن السؤال لماذا نحتاج إلى صيغة مفتوحة المصدر لسماع الأصوات ومشاهدة الفيديو؟.

حسنا ، ما ترخيص ogg ؟
إن ترخيص هذه الهيئة هو ترخيص حر يناسب القطاعات التجارية و الحرة ، فهي تحت رخصة BSD وهذا ما شجع الكثير من منتجي المشغلات الصوتية على دعم هذه الصيغة.

وما هو ترخيص MP3؟

إن صيغة MP3 الشهيرة مملوكة تجارية ، وتتقاضي مبالغ مالية كثمن استخدام براءة الاختراع ، حيث تتقاضي 25 $ لكل برنامج ينتج هذه الصيغة ، بالإضافة إلى 1% من قيمة أي ملف صوتي يباع منها.
لذى لجأ الكثيرون من منتجي الألعاب إلى استخدام صيغة ogg وذلك لتفادي شراء حقوق استخدام براءات الاختراع الخاصة بـ MP3.
ما الذي يميز ogg Vorbis عن بقية الصيغ التجارية؟
قد تكلمت أنه حر و استخدامه تجاريا أو غير تجارية لا يكلف أي شيء، هذا أحد المميزات الكبيرة بالإضافة إلى أنه يمتلك برامج حرة و مفتوحة المصدر قامت بتطبيق مواصفات ogg بشكل كامل وهي متوفرة للاستخدام و الإعداد و التخصيص على حسب الحاجة بالمجان.
قد تكون هذه المميزات غير مشجعة كثيرا ، ولكن صيغة ogg Vorbis تمتلك مميزات أخرى تجعل استخدامه أمرا ممتعا:
- في مقارنة مع الصيغ التجارية WMA  و LC-AAC تفوقت صيغة ogg في الجودة في ميدان معدل البت المنخفض ( أقل من 64 كليوبت في الثانية ).
- في معدلات البت المتوسطة والمنخفضة ( أقل من 128 كليو بت في الثانية ) أظهرت الاختبارات تفوق Ogg Vorbis على صيغ التجارية المنافسة (LC-AAC, HE-AAC, MP3, MPC, WMA).
- في معدلات البت العالية ( فوق 128 كليو بت في الثانية ) أظهرت صيغة Ogg Vorbis  تفوقها على صيغة MP3 و LC-AAC.
- في كل الأحوال صيغة Ogg  تنتج حجم ملفات أصغر مع الصيغ المنافسة.

هل يمكنني أن أحول ملفاتي MP3 إلى Ogg ؟
نعم يمكنك أن تحول جميع الملفات إلى ogg. ولكن يجب عليك الانتباه أن التحويل من صيغة مضغوطة إلى صيغة مضغوطة أخرى في الغالب فكرة سيئة. لأن هدف كل من MP3  و Vorbis  تحقيق أعلى مقدار من معدل الضغط وذلك بالتخلي عن أجزاء من الملف الصوتي ، فإذا قمت بالتحويل بين الصيغ ستحصل على ملف صوتي جودته أقل من ملف MP3.
إن موقع vorbis.com ينصح بعدم التحويل وذلك للحفاظ على جودة المقطع ، ولكن يشجعك على استخدام vorbis  منذ البداية عندما تريد تحويل القرص الأصلي إلى صيغة إلكترونية فهذا الطريقة تعطي نتائج أفضل ، بحيث تعطي حجم أقل و جودة أعلى.

ماذا عن Theroa ؟
حسنا ، إن هذه الصيغة تتطور بشكل متسارع وذلك لتواكب المستجدات القادمة ، وهي في وقتها الحالي تصلح للاستخدام على مواقع الوب ، وذلك لأنها تنتج بحجم أصغر مما يحافظ على كمية مرور البيانات من النفاذ.
وهناك جهود كبيرة من شركة ردهات و مؤسسة موزيلا و مؤسسة ويكيميديا لتطوير هذه الصيغة لتنافس الصيغة التجارية H.264.

ما البرامج التي تشغل صيغة Ogg ؟
يوجد العديد من البرامج الحرة التي تشغل هذه الصيغة و أشهرها VLC للمزيد حول هذه البرامج راجع هذا الموقع.

في نهاية هذه المقالة أتمنى أني قدمت شيئا جديدا إلى معلومات أيها القارئ الكريم ، وإذا أعجبتك هذه المقالة فانشرها في مدونتك أو موقعك ، وبين أصدقائك .

What is theora:

Theora is a free and open video compression format from the Xiph.org Foundation as part of their Ogg project.

What is Ogg? What is Vorbis? What is Xiph.org?

Vorbis is an audio codec, Theora is a video codec. Ogg is the transport layer that both are stored in, so a video file will be Theora-encoded data inside an Ogg file, while audio is normally Vorbis-encoded data inside an ogg file.

It is a free & open souce software.

Compiling theora on ubuntu 9.o4

compiling  theora is a simple process. As ubuntu is more specific for desktop user you have to ensure whether necessary packages are present.

for compiling you need GCC , make  etc like utilities. The best way to get these utilities is “build-essential” package. for that you required ubuntu 9.04 cd. Issue following command on terminal.

This install necessary packages.

Compiling & install theora

To install theora first you need to install libogg. download libogg-1.1.4 & use following procedure to install libogg.

Now you are ready to install theora

download libtheora-1.1.4 & use following procedure to install libogg.

now you  can convert any video file into theora format.

Finally all credits to shirish who told me to work with theora & gave valuable information about theora. This is my first attempt to do something in opensource. Once again thanks to shirish

So what’s the problem with the Theora decoder? From what I can see, there is no problem.  The story ranges from it’s not good enough to some unnamed “IP” problem that supposedly lurks down the proverbial dark alley.  Theora serves the purpose of a good quality, open, general-purpose web video decoder that everyone can use today without taking licenses.  Sure, there may be other codecs for different use cases, but for now we need at least one good, open, and unencumbered codec.

Two objections come up: one related to quality at given bit rates, the other related to unspecified IP encumbrances.  As to the first, there are ample discussions on quality by folks far more qualified than myself.  As to the second, I don’t see a problem and here’s why.

Does Theora comply with the W3C licensing policy? Yes. The licensing goals articulated by the W3C in Section 2 of the Patent Policy are to promote the widest adoption of Web standards that can be implemented on a Royalty-Free (RF) basis.  Thus, to qualify to be a W3C standard for the HTML 5 video tag, any codec must comply with the W3C Royalty-Free (RF) Licensing Requirements. (At the risk of over-simplifying, a bunch of folks who know alot and have many valid opinions have to agree as well).  The RF requirements provide in relevant part that “With respect to a Recommendation developed under this policy, a W3C Royalty-Free license shall mean a non-assignable, non-sublicensable license to make, have made, use, sell, have sold, offer to sell, import, and distribute and dispose of implementations of the Recommendation…” The policy further enumerates ten conditions that define detailed terms of the license requirements.

In this case, we know that Theora was derived directly from the VP3 codec originally developed by On2. In 2001, On2 open-sourced the VP3 codec and gave xiph.org a license to further develop and redistribute VP3 as part of Ogg under a BSD license.  The VP3 codec is what we now know as Theora. See FAQ on VP3 and Theora.  It’s nearly identical to VP3, varying only in framing headers.  At about the same time On2 open sourced VP3, On2 issued an express and unequivocal patent non-assertion statement related to VP3.  The statement, shown below, can be found publicly in the  VP3 libraries under libtheora 1.0:

“In addition to and irrespective of the copyright license associated with this software, On2 Technologies, Inc. makes the following statement regarding technology used in this software: On2 represents and warrants that it shall not assert any rights relating to infringement of On2’s registered patents, nor initiate any litigation asserting such rights, against any person who, or  entity which utilizes the On2 VP3 Codec Software, including any use, distribution, and sale of said Software; which make changes, modifications, and improvements in said Software; and to use, distribute, and sell said changes as well as applications for other fields of use. This reference implementation is originally derived from the On2 VP3 Codec Software, and the Theora video format is essentially compatible with the VP3 video format, consisting of a backward-compatible superset. On2 represents and warrants that it shall not assert any rights relating to infringement of On2’s registered patents, nor initiate any litigation asserting such rights, against any person who, or entity which utilizes the On2 VP3 Codec Software, including any use, distribution, and sale of said Software; which make changes, modifications, and improvements in said Software; and to use, distribute, and sell said changes as well as applications for other fields of use.”

Thus, we have an affirmative non-assertion statement by On2 declaring the use of VP3 (Theora) free of any patents owned by On2.  The statement is unconditioned and unqualified, unlike most actual licenses (meaning you can’t breach their non-assertion statement) and in substance it meets all of the W3C Royalty Free (RF) Licensing Requirements. The RF policy expressly allows the grant of a license to be “limited to implementations of the Recommendation and to what is required by the Recommendation.” Thus, it’s my interpretation the non-assertion statement applies to any and all On2 patents that cover the Theora reference implementation.

It seems clear that On2 intended that VP3 (implemented as Theora) would be available on an unencumbered basis for anyone to use. Perhaps On2 will further clarify or restate its intentions. Conversely, I don’t see a scenario where On2 could successfully assert a patent claim against anyone for implementing Theora (not to mention that it would contravene their good intentions).

Is Theora encumbered by patents? The process generally consists of looking at any patents held by the creator of the specification.  We did that and found On2 relinquished any claims on the Theora implementation consistent with the W3C policy.  The inquiry usually ends here.

Additional investigation further suggests that Theora is not encumbered. Theora has been around for a long time absent any claims as far we know.  Undoubtedly, VP3 has also received significant due diligence from customers of On2.  More importantly, VP3 was designed specifically to avoid any relevant patent thickets.   For more on this point, see the video from a recent Mozilla brown-bag discussion featuring Dan Miller, a co-founder of On2, along with Davis Freeberg, a video codec enthusiast, where Dan talks about the genesis of Theora. We also know that several companies have distributed Theora, including Apple which at one time made VP3 available for download as a Quicktime component.

Some additional precepts also inform the resulting conclusion. First, no recommendation or standard is ever “patent proof.”  At best, participants of the working group grant licenses, but that only covers participants. Similarly there are patent pools that grant licenses, but again, those only cover rights for the participants in the pool. So there’s always the possibility of a claim from those outside the standards group or patent pool.  Note, this is not to say in any way, that there’s no value in such groups, but the perception that they operate as a guaranteed prophylactic is false.

Based on what we actually know, Theora looks good.  It complies with the W3C patent policy and goals, and there haven’t been any patent claims that would indicate otherwise.  I welcome any comments, or better yet, anyone that wants to shed some further light in that dark alley.

En una entrevista realizada a Erik Möller, se dan a conocer nuevas herramientas de wikipedia que permitirán facilitar el subir vídeos en el formato ogg Theora.

Este es un formato 100% libre que puede ser utilizado sin limitaciones y sin tener que pagar ningún tipo de licencia (ver Licencia), el cual ya ah sido adoptado por el popular navegador Firefox, y próximamente también será soportado por Opera y Chrome.

Dentro de las cosas nuevas que se esperan encontramos: un nuevo reproductor de vídeo, plug-in de Firefox y herramientas en el servidor que facilitarán la conversión de formatos de vídeo.

My brother showed me this post at hacks.mozilla.org on how to do the much bitched about html5 video tags. So I totally had to do it, and I did.

Here is my page http://numberedhumanindustries.com/video

The cool thing is that you can have it degrade codecs and and even all the way to flash. The first (intro) video is this way, but the rest are theora/vorbis file (yeay freedom!) So here is a little howto.

First You need a place to store the vids that you can link to. If you have dropbox you could put the vids in your public folder and link there.

To have a just theora/vorbis vid (because you love freedom) the code looks like this:

</video

To have a theora/vorbis vid that degrades to mpeg4 the code looks like this:

Now if you need it to degrade all the way to flash (puke) then it would look like this:

ok that is the long and short of it. Not bad at all but you need to have Firefox 3.5 and some versions of Opera/Chrome/and possibly Safari with some extra codecs that screws the whole idea.

**EDIT: ok so I’m not smart enough to get the code to show up so just check out the mozilla hack page I was just copying from them anyway

La nueva versión del navegador más popular, aunque no el más usado, ya esta disponible en muchos idiomas, incluyendo varios en español.

La versión 3.5,  según dice la página oficial, es el primero con HTML 5, es el doble de rápido y trae soporte nativo, para Ogg Vorbis y Ogg Theora, esto significa , que no habrá necesidad de plug-in’s extras, para audio y video en este formato, por último me enteré de que es el navegador que ocupa menos RAM sin embargo no puedo encontrar el link a ese post :S..a actualizar!

Bajalo en español desde aqui

We now support the new [[video]] HTML tag when viewing movies from our site.

You’ll need Firefox v3.5+ (full or beta release) or Safari v4+ for us to show you a “try the new [[video]] tag” section under the “click to play” video area.

You can even persist a choice to always use it on our site (by us setting a cookie for you) (and you can change your mind and go back to the normal flash plugin based option).
