MetavidWiki extension has been written to take advantage of some of the
scalability features of mediaWiki. So performance should be scalable in
the same way that mediaWiki scales. (ie use a php accelerator,
memchache, squid proxies, mysql slaves & masters etc).
So while its requirements are certainly higher than just vanilla
mediaWiki (metavidWiki also includes semantic mediaWiki)... it should
scale in a similar way.
I can share the relative speed of the two ogg segmenting media serving
solutions:
mod_annodex ... is not that scalable since it does not cache seek
offsets and rewrites ogg pages as it sends out the stream. It takes
around ~700ms for both a cold and hot seek segmented media serving.
oggz-chop .. is faster ~190ms for cold seek and since its just byte wise
serving (does not rewrite media pages) the second request for that
segment will come from OS RAM disk cache ie ~10ms so with a good raid
and sizable amount of ram you could likely only be limited by the
bandwidth of your media server.
oggz-chop is still kind of new but you can grab it from the svn at:
http://svn.annodex.net/liboggz/trunk/src/tools/oggz-chop/
It has a few minor issues with a few frames freezes in VLC and possibly
some audio sync issues with quick time component.
I think Conrad/kfish may be soon addressing the above mentioned issues
and pushing it into the Debian repos soon... I will have to check with him.

Hi guys ,
I'm looking the metavid source code , when I've read about a
imprintlogo.so
in this page , http://slugforge.cse.ucsc.edu/gf/project/metavid/scmsvn/?action=browse&path…
on the end of the code.
But I dont't find the source of this vhook module.
Where I can find it for study and see it in action?
Thanks for your help
Bye

Hello,
I started getting some minimal progress on the Flash video support
along the lines of what Michael suggested. You can see an example of
pulling an .flv video from archive.org here:
http://www.urbanstew.org/MediaWiki/index.php5?title=Stream:Congress
What is implemented so far:
* if your environment supports Flash, Flowplayer should be an option
* you can view an .flv stream using Flowplayer - but all time
information is ignored
Right now, when a stream file is added, metavidwiki system appends
.anx to it, so the flashEmbed script takes .anx out of the filename it
gets. How should I address this for the long run?
Cheers,
Stjepan
Hi all,
My semester is finally ending so I'm able to slowly start working
towards the Metavidwiki GSoC project - very exciting! After chatting
with Michael a while back I've started working on integrating
flowplayer with mv_embed
(http://metavid.opengov.org/irclog/metavid.log.20Apr2008.html).
Anyway, after updating from the repository today I ran into a few
snags that should perhaps be documented (and I'd be happy to add them
to the wiki if appropriate). One thing that came up was that
Metavidwiki has a dependency on GD, which might not be a problem for
most people but PHP that comes with OS X doesn't support GD :-(.
There are some downloadable packages that do (e.g.
http://www.entropy.ch/software/macosx/php/) so there's an easy fix -
should I add this info to the wiki?
Also, I needed to change permissions on the stream_images directory or
MV_StreamImage.php complains. I don't remember that from the install
instructions - should I add this info somewhere as well?
Thanks,
Stjepan
