Horas depois do lançamento do iPhone 4, twitei sobre como seriam revolucionárias as novas capabilidades de VoIP do iPhone, batizado de FaceTime. Fiz questão de vasculhar a Internet para encontrar empatia naquela visão, mas aparentemente todos estavam facinados somente com o aspecto “videochamada” do aplicativo.

Today I spent several hours testing the almost amazing Samsung LED TV on a local store. More specifically the UN40B7000 model.
The image quality is great and all but I was more interested in the digital multimedia features included in these new models, branded Medi@ 2.0 (or Media 2.0). You actually plug these TVs on your [...]

Here are some technical details an analysis about the formats used by the Apple iPhone 3GS to record video.
This is an annotated screenshot of the excellent Mediainfo by Jerome Martinez.
Some notes:

We made a point-to-point SIP high definition video conference over a local area network. Another test used H.323 protocol. We also included my SIP-enabled Nokia E61i in the conference over the office WiFi network in a direct multipoint call simply calling [...]

After a long study of months I found this method to be the best way to rip/encode or backup my DVDs. The resulting digital file uses the best standards and technologies (as H.264, MP4, Matroska, AC3 etc), looks practically lossless to human eyes and has reasonable good file size (about 1 to 1.4GB per [...]

Its a Nokia E61i.
The Nokia E Series smartphones are currently the most advanced in the market. Some may say iPhone but there is no more than great usability and fancy-ness on it.
These are a few characteristics I like in E61i:

WiFi with [...]

A Apple finalmente deu a data de lançamento do iPhone: 29 de junho.
Em seu site há 3 lindos videos mostrando a operação fácil do aparelho. Mas exige Quicktime e sem isso não funciona. Para um leigo.

Andei estudando tecnologias de compressão de vídeo e é um mundo fascinante. Tudo sobre Linux.
DivX e Xvid são compressores ainda bons mas de gerações anteriores. O mais moderno e avançado é o H.264 também conhecido por MPEG-4 AVC, padrão ISO. Uma das melhores implementações desse compressor é livre: o projeto x264.
E sobre containers, um dos [...]
