theora - Nov 2008 - Theora promotion material

Hi all,

A while back I wrote in about wanting a theora promotion video. Having a
few lazy minutes left in the day, I decided to do some coding to create
a small movie. However, I encountered two problems:
- The artwork completely &$@(%sses, but then again I'm no artist.
- How do you actually embed the movie into a SVG file? Otherwise I'd go
for HTML but a working example would be cool.

The attached program can be used to create a banner movie. It will
scroll the image you give it as the first argument over a smaller image
and then use ffmpeg2theora to create a theora movie from the sequence of
images.

After extracting and installing ffmpeg2theora on your system, running:
./theora_banner.py theora_on_the_move.png

Should result in a small movie and a directory filled with images. The
movie looks horrible (again, I'm no artist) but the idea should be
clear. So if anybody can help me with artwork and a working theora in
SVG example, I'd be very pleased to trade for my page of code ;)

Greets,
  Bram

You can embed it in HTML with a compatible browser using:

<video src='foo.ogg'></video>

In SVG you can also embed it using SVG video in a compatible browser:

<svg xmlns='http://www.w3.org/2000/svg'
xmlns:xlink='http://www.w3.org/1999/xlink'>
  <video xlink:href="foo.ogg"/>
</svg>

If the browser doesn not support video in SVG, but does support it it
in HTML, you can use foreignObject:


<svg xmlns='http://www.w3.org/2000/svg'
xmlns:xlink='http://www.w3.org/1999/xlink'>
<foreignObject>
  <div xmlns="http://www.w3.org/1999/xhtml">
    <video src="foo.ogg"/>
  </div>
</foreignObject>
</svg>

Unfortunately the 'compatible browser' is the issue. Opera supports
video in SVG. Firefox does not. Firefox and Opera have experimental
HTML video support for Theora. Safari has HTML video support but not
built in for Theora, it needs XiphQT plugins.
