theora dev - Dec 2008 - Slideshow with Ken-Burns Effect

Hi everybody,

I've had some time and so I added a slideshow creator with the
Ken-Burns-Effect to the Ogg Video Tools. Feel free to visit the following page:

http://www.server.streamnik.de:88/test.html

It's best viewed with the Mozilla Firefox 3.1 Beta 2, but a Cortado Player
is also available for the other browsers.

The code is actually not publically available, as I would like to add a lot of
command line options to customize the slideshow. Additionally I will add some
other features. The next release will hopefully be before christmas, so stay
tuned!

Yorn

Nice one!
I'm curious how you created the Ken-Burns-Effect on the images and
turned that into Theora.
BTW: my firefox3.1 starts with a delay on the audio on that file and
then is very choppy.

Cheers,
Silvia.

Hmm, that is nice, although I see nothing on the website itself using ff
3.0.4 (I had to cut and paste the video file from the page source then dl
with wget).

I will have to add this so called Ken Burns effect to LiVES - actually I
have already been doing this by resizing, panning and then trimming the
center, I had no idea it had a name !


Whilst on the subject of LiVES, please note that LiVES 0.9.9.4 was released
a few days ago and it has the previously mentioned support for instant
opening of ogg/theora files. So I hope you will all go out and test this !

Theora encoding was also fixed in this release ! I am now working on
creating a library of VJ loops in ogg/theora format using LiVES. The first
of these is available here:

It's awesome to see people that are already starting to use the new
HTML 5 video element!

I only have a few (very pedantic, sorry) suggestions.

IMHO it's better to use the ".ogv" extension for Ogg/Theora
videos,
just in case people download the file and have the ".ogg" extension
associated with a music player program that can play Vorbis files but
not the video;

You are using a very high video quality setting that results in more
that 230 kBytes/s; maybe for internet streaming a smaller value would
be better while still giving sufficient quality?

The attributes "autoplay" and "controls" of the video
element are
boolean attributes, which means that they are enabled when they are
present; this implies that <video controls="false"> actually
*enable*
controls; the simplest way to use them is <video src="..."
autoplay>
(only the attribute name, without "=" and any value), but if you
prefer an XML-like attribute value you should specify
autoplay="autoplay" or simply autoplay="".

Yes, HTML is ugly. ;-)

To disable them, simply omit the attribute altogether.

Anyway, keep up the good job!

How old is your ff 3.1 version? It played well on latest trunk on
Linux. The only choppiness was when it needed to buffer due to slow
network.
