Here it is! I has been developing quietly, but some of its features can be already seen implemented using the newly released Mozilla Firefox 3.5 or latter. The standard specification is still a work in progress, and what has been done can be read in the draft outlined by W3C in this page. In the first issue of the Virtual Poetry Project, the video tag, which is part of the html 5 standard, can be seen side by side with flash. I put video in both OGG and FLV formats, the first one embedded using this tag:

<video src="" id="caceria" controls> Theora decoder not found. You need <a href="" target="_blank">Mozilla Firefox 3.5 or higher</a> to see this page.</video>

This piece of code allows the embedding of ogg files, which have buit-in support in the latest releases of Firefox and Google Chrome, and also in some development versions of Opera (this will be implemented probably in the next stable release). The choice of the ogg format was a recommendation done by Opera Software Chief Technical Officer, HÃ¥kon Wium Lie, who explained that a royalty free format should be universally supported in the same way the PNG image format is today supported in all browsers. The aim is to make the embedding of audio an video as easy as the embedding of images in html is today. However, the WATHWG (in charge of the specification) got cold feet. They rejected the recommendation advocated by Opera and Mozilla. The change done in the text of the specification can be seen here. The text of You can read more on the controversy in this Wikipedia article and also in the W3C Q&A blog. For a full explanation and examples of code, you can see this page in the Mozilla Developer Center.
