Aula2: Utilizando O Canivete Suíço Mencoder Capacitação 2010
Capacitação realizada através de parceria entre o Núcleo de Tecnologia Educacional Municipal - NTM Núcleo de Tecnologia Educacional Estadual - NTE de Volta Redonda CapacitaçãoCapacitação 20102010 Aula2:Aula2: UtilizandoUtilizando oo CaniveteCanivete SuíçoSuíço MencoderMencoder O MEncoder é uma ferramenta em linha de comando para encodação de vídeos sob a Licença Pública Geral (GPL). O MEncoder é distribuído juntamente com o MPlayer e permite converter todos os formatos de vídeo aceitos pelo MPlayer para um grande número de outros players. Possui diversos filtros de áudio e vídeo para a manipulação dos arquivos. Devido a enorme quantidade de opções, o MEncoder pode parecer pouco amigável no começo, mas ele é uma ferramenta extremamente poderosa para conversão de vídeo. Alguns frontends foram desenvolvidos para torná- lo mais acessível. O Básico Um mal entendido muito comum é o de que o MPlayer, por ser capaz de reproduzir diversos containers e codecs de áudio e vídeo, seria também capaz de codificar arquivos nestes mesmos formatos. A lista de codecs para codificação de mídia é muito longa, mas alguns de código livre não estão inclusos por exemplo: FLAC e Theora. Mas não é algo com o que se preocupar, ainda restam diversas opções, até mesmo se você deseja codificar um arquivo para reprodução em Windows ou Mac. Antes de entrar em detalhes, vamos observar o funcionamento básico num processo de re-codificação de um arquivo em um formato que o MPlayer não pode reproduzir, para o formato MPEG4: mencoder arquivo.flv -o arquivo.avi -ovc lavc -oac pcm Explicando cada opção -arquivo.flv: nome do arquivo de vídeo original que você deseja recodificar. -

A Health Index of Open Source Projects Focusing on Pareto Distribution of Developer’s Contribution Hirohisa Aman∗, Aji Ery Burhandennyy, Sousuke Amasakiz, Tomoyuki Yokogawaz and Minoru Kawahara∗ ∗Center for Information Technology, Ehime University, Matsuyama, Ehime 790-8577, Japan yGraduate School of Science and Engineering, Ehime University, Matsuyama, Ehime 790-8577, Japan zFaculty of Computer Science and Systems Engineering, Okayama Prefectural University, Soja, Okayama 719–1197, Japan Abstract—Open source software (OSS) products have been the popularity and the user assessment, they are based on the broadly utilized for the IT business as well as the personal use products rather than the project. Recently, there have been in recent years. Software companies can receive much benefit some studies focusing on the project operation, including the from OSS products in terms of cost to develop and maintain their products. However, there are also risks that products of contributions of OSS developers [2]. It would be promising to interest might become no longer being successfully maintained focus on the developers in order to discuss the project’s health by the OSS developers because a successful maintenance is not because their contributions drive the OSS project. While an obligation of developers. In order to evaluate a project’s health analysis of individual’s contribution must be beneficial, such from a perspective of a macroscopic trend analysis, this paper a detailed analysis tend to be unfit for capturing the entire focuses on the distribution of the developer’s contribution to an OSS project, and analyzes the relationships of distribution spectrum of the project. Therefore, in this paper, we will features with the quality of products. -

Video - Dive Into HTML5
Video - Dive Into HTML5 You are here: Home ‣ Dive Into HTML5 ‣ Video on the Web ❧ Diving In nyone who has visited YouTube.com in the past four years knows that you can embed video in a web page. But prior to HTML5, there was no standards- based way to do this. Virtually all the video you’ve ever watched “on the web” has been funneled through a third-party plugin — maybe QuickTime, maybe RealPlayer, maybe Flash. (YouTube uses Flash.) These plugins integrate with your browser well enough that you may not even be aware that you’re using them. That is, until you try to watch a video on a platform that doesn’t support that plugin. HTML5 defines a standard way to embed video in a web page, using a <video> element. Support for the <video> element is still evolving, which is a polite way of saying it doesn’t work yet. At least, it doesn’t work everywhere. But don’t despair! There are alternatives and fallbacks and options galore. <video> element support IE Firefox Safari Chrome Opera iPhone Android 9.0+ 3.5+ 3.0+ 3.0+ 10.5+ 1.0+ 2.0+ But support for the <video> element itself is really only a small part of the story. Before we can talk about HTML5 video, you first need to understand a little about video itself. (If you know about video already, you can skip ahead to What Works on the Web.) ❧ http://diveintohtml5.org/video.html (1 of 50) [6/8/2011 6:36:23 PM] Video - Dive Into HTML5 Video Containers You may think of video files as “AVI files” or “MP4 files.” In reality, “AVI” and “MP4″ are just container formats. -
Tehnoloogiad, Millel Põhineb Kodune Multimeedium
Multimeedium kodus Tehnoloogiad, millel põhineb kodune multimeedium Kodune multimeedium sai alguse tavalistest CD-DA (aasta 1980) plaatidest, digifotodest (esimene müügile jõudnud digifotoaparaat oli Dycam Model 1 aastast 1988). Video lisandus QuickTime (aastast 1991) ning Windows Media (algselt Video for Windows, aastast 1992) videoklippidena, mida oma koduarvutil enam-vähem kuulata/vaadata õnnestus. Tänu meedia- kompressiooni arengule (mp3, mpg, aac, ogg jms) on digitaalne meedia muutunud jõukohaseks ka kodusele arvutivõrgule ning tekkinud on hulk seadmeid, mis seda kõike jagada/kasutada suudavad. Praeguses mõistes on kodune multimeedium eelkõige oma meedia jagamine erinevate seadmete vahel. Järgnevalt lühiülevaade olulisematest tehnoloogiatest, mis selle võimalikuks teevad. Taskuhääling ehk podcast podcastMõiste „podcasting“ võeti kasutusele aastal 2004 ja see kombineerib sõnu „iPod“ ning „broadcast“. Podcasti avaldamine kannab nimetust podcasting, omaniku (avaldaja) nimetuseks podcaster, kasutamine podcatching ja vastavat tarkvara podcatcher. Eestikeelse mõiste „taskuhääling“ pakkus välja Valli Voor (tõlkefirmast Tilde) paralleeliks mõistele „ringhääling“. Taskuhäälingust räägitakse sageli ka kui asünkroonsest raadiost või nõuderaadiost (ondemand radio) kuid nende vahel on teatav erinevus – taskuhäälingu puhul ei pea kasutaja ise kontrollimas käima, kas on uusi saateid lisandunud. Eesti taskuhäälingu näitena võib nimetada KUKU taskuhäälingut: http://podcast.kuku.ee/ Taskuhääling põhineb RSS (Really Simple Syndication) tehnoloogial -
Remote Access of Home Network from Mobile Device Using DLNA and Linux
Remote Access of Home Network from Mobile Device using DLNA and Linux RIKARD GUSTAFSSON AND GUSTAV REIZ Master’s Thesis at the Department of Computer Science Advisor/Examiner: Boris Magnusson Advisor: Stefan Ekenberg February 15, 2010 Abstract In today’s technically aware society comfort has become a big demand. From this demand the DLNA standard rose up in order to let people fuse all of their technical devices together, to share, to view and to transfer their digital content. In parallel with this development, our mobile phones are evolving into more and more advanced multi-purpose devices which we rely on in many of our daily activities. In this Master’s Thesis the aim is to conjoin these two trends in order to develop a prototype system in which a user is able to control his home network with the use of a mobile phone over the cellular network or when connected to the Internet through Wi-Fi. The user will be able to connect to, and control, his home network and the devices within. Analysis of available related solutions, the advantages and disad- vantages of them, are first presented. A new, more suitable, solution is thereafter proposed. Referat I dagens tekniskt medvetna samhälle så har bekvämlighet blivit ett stort krav och det är utifrån detta krav som den nya DLNA standarden växte fram. Med hjälp av DLNA möjliggör man för användare att integrera sina tekniska enheter med varandra. Därigenom förenklas möjligheterna att dela, titta på och hantera digital media. Parallellt med denna utveck- ling så blir våra mobiltelefoner mer och mer avancerade och spelar en allt större roll i vår vardag. -
Video Encoding with Open Source Tools
Video Encoding with Open Source Tools Steffen Bauer, 26/1/2010 LUG Linux User Group Frankfurt am Main Overview Basic concepts of video compression Video formats and codecs How to do it with Open Source and Linux 1. Basic concepts of video compression Characteristics of video streams Framerate Number of still pictures per unit of time of video; up to 120 frames/s for professional equipment. PAL video specifies 25 frames/s. Interlacing / Progressive Video Interlaced: Lines of one frame are drawn alternatively in two half-frames Progressive: All lines of one frame are drawn in sequence Resolution Size of a video image (measured in pixels for digital video) 768/720×576 for PAL resolution Up to 1920×1080p for HDTV resolution Aspect Ratio Dimensions of the video screen; ratio between width and height. Pixels used in digital video can have non-square aspect ratios! Usual ratios are 4:3 (traditional TV) and 16:9 (anamorphic widescreen) Why video encoding? Example: 52 seconds of DVD PAL movie (16:9, 720x576p, 25 fps, progressive scan) Compression Video codec Raw Size factor Comment 1300 single frames, MotionTarga, Raw frames 1.1 GB - uncompressed HUFFYUV 459 MB 2.2 / 55% Lossless compression MJPEG 60 MB 20 / 95% Motion JPEG; lossy; intraframe only lavc MPEG-2 24 MB 50 / 98% Standard DVD quality X.264 MPEG-4 5.3 MB 200 / 99.5% High efficient video codec AVC Basic principles of multimedia encoding Video compression Lossy compression Lossless (irreversible; (reversible; using shortcomings statistical encoding) in human perception) Intraframe encoding
